Improving Your Color Image
The color response of the P4 color camera is quite good even when using white LED's
without color correction. A
color response for those using white LEDs.
If you are using a different light source, a suitable color correction matrix should be entered
in the camera. You will require a Gretag Macbeth ColorChecker with 4 x 6 color elements
that you can scan past the camera to complete the generation of the matrix.
