14.9 Using Sequential Pattern Filtering The disadvantage, as we have seen, of sequential pattern ďŹ ltering is that there is a danger of getting interference patterns between the frequency of a pattern on the set and the frequency of the pixels on the sensor. The simple answer is to have a much higher pixel count on the sensor. As sequential patterned sensors are usually CCD devices and are therefore already expensive, substantially increasing the pixel count will put that already considerable cost up at what may be an alarming rate. If you can afford to do this then all will be well and you should have an excellent image from your camera that gives an RGB output with little or no after-processing being needed. This could be a considerable advantage when you get to post-production.
