1.0 COMPREHENSIVE PICTURE SETTING OVERVIEW

1.0 COMPREHENSIVE PICTURE SETTING OVERVIEW During the manufacturing process, every units are will have slight differences. The Blackwing One are manufactured to obtain the most homogenous grey tracking and color balances to obtain vivid colors and correct flesh tones. Understanding colors and how the human eye detects them. The human eyes can detect the colors thanks to the development of specialized cells into the retina. These cells are classified into three categories. The first kind of cells is specialized and will easily detect a given spectrum centered on the green frequency; another one on the blue and the last one on the red. By exciting these cells, a given color will be detected and transmitted to the brain as three stimuli with different intensities and our brain will understand this particular color as a combination of green, blue and red. Two different persons will not see the same thing, and being a living part of our body, the eye evolves as we live and the our vision is modified. By example a baby can only see black and white and cannot detect small objects. The growing child will have his adult vision only between 4 and 6 years. It is important to remember that even if each color can be precisely measured, they are processed by the eye and interpreted by the human brain within a visible spectrum, which can vary from one to the other. And consequently a projector calibration is meant to be adapted to your customer visual perception and not to be adjusted strictly to a specific standard.

6.0 CALIBRATION STEPS

6.0 CALIBRATION STEPS In this paragraph, you can follow a step by step calibration method to enhance the projected picture. The calibration steps are not to be followed in this strict order to obtain an accurate calibration This document only intend to give a comprehensive explanation on how each picture setting impact on the resulting picture and to determine how they should be set depending on the projection system setup. You won’t need professional tools and software to obtain a very satisfying calibration.

6.1

General picture setup 1.1

Background Color

This setting will determine the background color, choose between light blue or black background to be displayed when there is no signal (video source is switched off, no synchro signal or out of range). It is recommended to select a blue background during the first install to quickly diagnose a source issue and once the installation is completed, switch back to the black background.

1.2

Keystone Adjustment

The Keystone adjustment is to be used only when the vertical and horizontal optical shifts needs exceed 30% horizontally and 60% vertically . Then the use of the Keystone video-processing correction is mandatory to achieve a picture that perfectly fits into the screen.

1.3

Alignment

A 3-Chip projector requires a pixel alignment adjustment when the vertical and horizontal offsets used are different from the default manufacturing setting. The Blackwing One panels are aligned at the factory with 0% vertical and 0% horizontal offset. When setting a different optical offset, the pixels will be slightly shifted due to the diffraction phenomenon into the light engine depending on their color and also because the light paths of each color channel do not ideally compensate each other when the lens is moved. • Typical Use: when the projector uses more than 20% vertical or horizontal offset. • You can detect a wrong Alignment with a white figure across a black background. It will display a colored contouring. The texts will also have a colored shadow. • An internal test pattern is generated during the Alignment setup.

6.2

Light configuration / optimization The Blackwing One projector is designed to perform in bright environments and dark rooms. By featuring two lamp modes and 10 lens aperture steps, it can easily be set to any lightning conditions.

2.1

Picture Mode (RCU)

There are three pre-configured picture modes and three user modes. When modifying or selecting a Picture Mode the settings are memorized and can be called back using the dedicated buttons on the remote control unit. You can switch between 6 Picture Modes: • Standard • Dynamic • Theatre • User1 • User2 • User3 Typical use: Select the most convenient Picture Mode depending on your video source and light environment. By example it is recommended to use the “dynamic” Mode in a bright living room, “standard” Mode for a DVD or TV projection in a dimmed environment and “theatre” for movie projection in a dedicated dark room. You can modify any parameter of a given picture mode and restore the initial default settings with a system reset (Menu->Initial Setup->System reset).

2.2

Lens aperture (RCU)

The lens aperture can dim down the light output of the projector. This setting is configured for each Picture Mode of any selected Input. Adjust the Lens Aperture from 100% down to 10%. The required light output is mostly determined by the ambient light environment and the screen specifications (size and gain). A small screen in a dark room will require a few light then the lens aperture will vary from 10% to 30%. Besides, a big screen in a bright environment will require a fully opened aperture. • Typical use: If the projector is used in a living room where the lights are not necessarily switched off, you can configure two Picture Modes using two different lens apertures: one when the lights are on, and the other one

6.3

Input dependant settings Some picture settings are input dependant and will not be modified upon switching between Picture Modes. They have to be configured for each input: HDMI1, HDMI2, VGA, Component, Video and S-Video. These settings will tell the projector how to deal with the sources before considering the setup environment. The following settings have to be configured prior to the Picture Modes.

3.1

Aspect ratio Selection (RCU)

The aspect ratio selection determines how the source will be displayed to the screen by the projector. As many of nowadays sources are able to output multi-format video signal, the Aspect Ratio can be select using directly the remote control button “Aspect” • Standard: this setting keeps the original aspect ratio of the source. • Full screen: this setting will distort the input signal to fit the entire screen. If your source is 4:3 the picture will be enlarged to fit the 16:9 aspect ratio of the screen. If your source is originally 16:9, this setting will be equivalent to standard setting. • Cinemascope: this setting is to be used with anamorphic lens. It will vertically stretch the picture. • Converted 16:9: this setting is to be used with a fixed anamorphic lens to display the entire 16:9 picture into the 2.35:1 screen when necessary. • Virtual Wide: this setting is available when the source is originally in 4:3 format and it will be enlarge non-linearly to fulfill the 16:9 screen.

3.2

Cinemascope AR (*), Converted 16:9 AR (**)

When the Blackwing One is installed with an anamorphic lens to display scope movies, the Blackwing One doesn’t need an external signal converted such as scalers. The Blackwing One is able to video-process the input source to display it into a 2.35:1 screen. The vertical stretch is performed by using the Cinemascope Aspect Ratio, and the horizontal squeeze is performed with the Converted 16:9 Aspect Ratio. There are two available anamorphic kits available: the Wide System and the 2.35 THEATRE System. • The Wide System is a fixed anamorphic lens system dedicated to 2.35:1 projection using the Cinemascope Aspect Ratio. But it can also display 16:9 content into a letter boxed 2.35:1 screen. (black bars on the left and right of the 16:9 picture) by using the Converted 16:9 Aspect Ratio. • The 2.35 THEATRE System is a motorized lens system that will perform the best performances for 16:9 using Full screen Aspect Ratio and 2.35:1 formats (using Cinemascope Aspect Ratio), maximizing both light output and resolution in any circumstances.

Cinemascope AR When selecting the Cinemascope Aspect Ratio, the coefficient of the distortion can be configured to finely adapt the movie format to your screen. In most latest Blu-ray releases, the movies are encoded in 2.37:1 but there are also 2.35:1 and 2.39:1 formats. The Cinemascope AR can be set up to 2.50:1

2

Converted 16:9 AR When the anamorphic system attached to the Blackwing One uses a fixed lens, the Converted Aspect Ratio is selected to restore the 16:9 source letter boxed into the 2.35:1 screen without loosing any picture information. You can configure the coefficient of distortion from 1.78 down to 1.30 to reduce the width of the black bars on the screen.

3.3

Black Level Setup (0IRE - 7.5IRE)

The first Black Level Setup can be configured to 0 IRE or 7.5 IRE. Historically the NTSC standard use a level of 7.5IRE to display a totally dark picture besides the PAL or SECAM formats use a 0 IRE level. During the move from analog to digital and during a format conversion such as Zone1 (USA) to Zone2 (Europe) the NTSC black level may be maintained or not to 7.5 IRE. Typical Use: When connecting a Zone 1 DVD-Player using Video or S-Video inputs, the black bars will be wrongly displayed as grey bars, select 7.5 IRE to restore the original blacks.

3.4

Black Level Adjustment (Input Black level)

The Black Level Adjustment is a very important setting during picture Calibration, it determines the minimum level attributed to the visible picture. With an incorrect setting of black level, you may loose details in dark scenes in a dark movie, even if you try to compensate with the brightness/contrast control. Typical use: The native black level of the projector is determined with its light output. To check the native black output you can select Converted 16:9 Aspect ratio and compare the vertical black bars obtained (projector black level) to the horizontal top and bottom black bars of a 2.35:1 movie (encoded black level). Typical Picture: Use the internal pattern of your source if available, if not, use a calibration DVD to obtain the darkest

6.0 CALIBRATION STEPS black and the whitest white that your source can display. Then raise or lower the black level adjustment from 0 to 100 until all the details in the black of your source matches the projector black level. Doing so ensures that the projector restores the picture at the maximum contrast possible. Test Pattern: Brightness pattern, also called black level pattern, super-black bars and below-black levels. NB: In order to obtain the blacker-than-black levels, you must have a video source that supports the so-called “super-black” function. If your source doesn’t support this function, it should be intended and doesn’t mean that your source is defective but that the source has already clamp the blacker-than-black levels to standard black. Then just lower the black level adjustment until the 4IRE black level of your test pattern is barely visible.

Wrong black level

The Black level is correctly set when the below-black bars of the PLUGE become invisible

3.5

White Level Adjustment (Input White level)

The White level Adjustment is a very important setting during picture Calibration. It determines the maximum level attributed to visible picture. With an incorrect setting, you may loose details in very bright scenes or obtain a low brightness for bright scenes. Typical use: The maximum brightness generated by the projector defines the brightest white that may be projected at the screen. This setting ensures that the projector uses the full available range to display colors and to obtain a smooth grey scale. Typical Picture: Use the internal test pattern of your video source if available and set the White Level adjustment from 0 to 100 until the 100 IRE output level from your video signal matches in the maximum brightness of the projector. Typical Test pattern: Contrast, White level also called super-white bars or above-white levels.

3.6

RGB Adjustment (RGB input must be selected)

When connecting an RGB input to the Blackwing One, you can finely tune the picture clock and clock tracking.

3.7

HDMI Signal (HDMI 1 or HDMI 2 inputs must be selected)

The Blackwing One HDMI inputs comply with the latest HDMI standard version 1.3. But they are also compatible with HDMI 1.2, HDMI 1.1, HDMI 1.0 and DVI-D. The HDMI inputs can detect which standard is currently used and will automatically apply the correct settings to decode the digital signal to restore the correct colorimetry (YCbCr or RGB colorspace) and the correct levels (PC levels, or Video levels). However, when using additional components between the video source and the Blackwing One projector such as DVI to HDMI adapters, video splitters or HDMI repeaters, the signal may be altered and report an incorrect HDMI format, leading in most case, to a wrong level detection, and in the worst cases to a wrong color decoding resulting to a pink or green picture. If this happens, manually select the correct HDMI level and HDMI Color Space.

6.4

Customizing the Picture Modes The Blackwing One projector has three pre-configured Picture Modes (standard, Dynamic and Theatre) and three user modes. They can be customized to perfectly match your projection setup. To restore the original settings you may perform a System Reset. To perform a picture calibration from scratch, it is recommended to begin with a User Picture Mode instead of the pre-configured Picture Modes.

4.1

Color Temperature

R599769 - Blackwing One Setting

7


6.0 CALIBRATION STEPS The Color Temperature can be set to low, medium or high. The recommended setting is medium for movies and TV projection. You can set to a warmer temperature by setting the color temperature to low or to colder temperature setting it to high. Typical use: to obtian a colorimetry that matches HDTV broadcast or Blu-Ray movies, choose the default setting: medium.

4.2

Custom Color Temperature

The user custom color temperature is used to define a custom color balance that will be assigned to one or more Picture Modes. Using the user color temperature can provide better results than the preset settings low, medium and high depending on your projection setup and light environment. You can also make a custom color balance to create a light ambiance that will better match your projection room interior and lightnings. Typical use: To define a custom User color temperature, you have to set a precise color balance for the black level and white level by doing so: Test Pattern: 100 IRE white, decrease the Red, Green and Blue gains to obtain the desired color temperature and a perfect white balance, depending on your objective, you may use a colormeter to achieve a given white target such as ITU-R BT709 CIE D65 White Reference (x,y = 0.3127, 0.3290) or DCI v1.2 White reference (x,y = 0.3140, 0.3510) Once the white level is correctly adjusted, display a black pattern between 0 IRE and 20 IRE depending on the sensitivity of your sensor. Set the correct Red, Green and Blue bias settings to obtain a neutral color balance in dark scenes.

4.3

Brightness / Contrast adjustment (onscreen Black Level and White Level)

The Brightness and Contrast setups (commonly called black level and white level setups) are very important because they will define the overall depth and dynamic of the picture at the screen within smooth color gradations. (to achieve the commonly called 3D effect). The brightness and contrast are two antagonist controls, the action on the value of one parameter requires a modification on the other one. As seen before section 3.3, page 5, the classical black levels and white levels can easily be set using the Black Level and White level Adjustments in the Input Signal menu. Once the input Levels are determined, you can configure many sets of brightness and contrast adjustments into different Picture Modes that will suit a particular setting of Color temperature, Lens aperture and Gamma value. Then you can use and recall each set when switching between Picture Modes. Typical use: When connecting a multi-media box or game console such as XBOX360 or PlayStation3 to the HDMI input in a bright environment, you can select the Dynamic Picture Profile (high brightness settings) for general purpose. But when you use the game console to display a movie with no light, you can set a User Picture Mode with higher gamma and a different lens aperture settings like Theatre Picture Mode. To do so, you will have to lower the picture brightness to display deep blacks and set the contrast to compensate the white level changes to obtain a great picture depth in the new darker projection conditions. Typical use: With the new light environment, set a new Picture Mode and adjust the picture brightness and contrast. NB: It is recommended to modify the Input Signal Black level and White Level adjustments (Input setting, not Picture mode settings) in the darkest environment possible. Then adjust the different Brightness and Contrast balance to brighter environments. Test Pattern to be used during this setting: Brightness, Contrast, White Level, Black level, super white and super black.

4.4

Color / Hue and Blue Only

The Color and Hue adjustments can be performed using a blue filter or by activating the Blue Only setting. Doing so will let only the blue channel to be displayed, making possible a fine tune of the color and hue adjustment using colored test pattern. Test pattern: Use the Color/Hue test pattern, with blinking blocks if available to make this adjustment easier. Use the filter or activate the Blue Only option and set the color value so that the blinking box disappear and until the bands appear uniform. It is important that you use the Color/Hue test pattern corresponding to your source format because the primary and secondary colors coordinates may vary from a standard to another. Use a NTSC calibration disc for a Zone 1 DVD

SMPTE colorbars

Incorrect Color and Hue settings

Color and Hue settings are correct when the blue bands appear uniform.

4.5

Sharpness

The Sharpness setting can be optimized by using the sharpness or frequency burst test patterns. Set the sharpness level until you can clearly see the small details without blur or white contouring. With HD sources, the sharpness control can be finely set when focusing on the lettering of the test pattern.

With SD sources, set the sharpness using multi burst patterns over white. background. Rise the sharpness until the bars turn from blurry to crisp. With HD source, you should focus on HD test patterns with white lettering over a grey background.

4.6

Detail Enhancement (RCU)

The detail Enhancement setting gives an alternate method to sharpen High Definition contents and to increase the perceived details for Standard Definition contents during the upscaling process to Full-HD resolution. It is

R599769 - Blackwing One Setting

9


6.0 CALIBRATION STEPS recommended to set it off with high quality video materials, set it to low with good quality Standard definition inputs, and set it to higher level for low quality materials such as compressed content and broadcast TV programs. This setting can also be accessed using the ”FOCUS“ button on the RCU.

4.7

Gamma selection

The gamma defines how grey scale is rendered at the screen by the projector. Depending of your screen gain and light environment, you may change the gamma response of the projector to obtain vivid colors and accurate grey scale. Lower the gamma setting to gamma1 in bright environment, use higher gamma values such as gamma 3 or gamma 4 for dark rooms to obtain cinema-like pictures. In a high contrast setup, ie: no parasite light reflecting to the screen, you may select higher gamma such as gamma 4. Test Pattern: display at the screen a step of grey shades, you must see each step of the bright area and in the dark portion of the test pattern.

6.5

Advanced Calibration The advanced calibration settings are hidden from the classic menu because they need advanced colorimetry knowledge and professional tools to perform an accurate adjustment. To access the advanced calibration settings, you must enter the Service Menu by pressing sequentially on the Remote Control Unit the following buttons: Ok, Esc, left, Right and Menu or from the back panel buttons, holding Ok+Esc+Source buttons

5.1

User Gamma

Each input can be configured with a different User1 to User3 gamma setting. All the Picture Modes for this input will share the User 1 to User3 settings. The User Gamma gives access to a wider range of gamma values and to a fine tuning of the grey scale balance: • You can then set a global value to gamma by modifying the three color channel RGB altogether, and check that the gamma curve obtained is correct with a colormeter. • You can also finely tune the greyscale balance by modifying independently each color for each IRE steps with black to white test patterns.

5.2

TNR

The Temporal Noise Reduction function is used to reduce the temporal digital noise on the picture. Adjust the TNR value to: Off, Low, Medium or High for each input. Temporal noise Reduction can be configured for each Picture Mode of each input independently.

5.3

MNR

The Mosquito Noise Reduction function is used to reduce the Mosquito noise generally found in compressed digital video signals such as television broadcast or compressed movies. Adjust the TNR value to: Off, Low, Medium or High for each input. Mosquito Noise Reduction can be configured for each Picture Mode of each input independently.

5.4

BAR

The Block Artifact Reduction function is used to reduce digital noise on the picture using a block scaling method. Using a large portion of the picture to reduce the digital noise ensures a higher quality filter. Adjust the BAR value to On or Off for each input. Block Artifact Reduction can be configured for each Picture Mode of each input independently.

5.5

Selective Color

The Selective Color menu gives a perfect control of the saturation and Luminance of each primary and secondary colors. The colors can be configured independently for each Picture Mode of each input so that you can easily compensate a given light ambiance when the projector is to be used with ambient light. Make sure to use the correct source pattern for each input as each primary and secondary colors coordinates vary from a standard to another.

5.6

LTI

Luminance transition Improvement can be configured for each Picture Mode of each input independently. The LTI is not approved for movie calibration because it dynamically change the color balance during the show. But it can be useful for still pictures like a slide show and low quality broadcast TV to enhance the picture quality.

5.7

CTI

Chrominance transition Improvement can be configured for each Picture Mode of each input independently. Same as LTI but applied to Chrominance.
