 The cpa command takes several seconds to complete. The slower the line rate, the
longer it will take.
 On completion of the ‗cpa' command, you should see an image from the camera that
is white balanced with all three colors at the target level you set.
You are now ready to evaluate the image quality of the camera under your operating
conditions.
6. Improving Your Color Image
The color response of the camera is quite good even when using white LED's and even
without color correction. The camera has a factory set white LED color correction matrix
that can be selected to improve color response for those using white LED's. If you are using
a different light source, a suitable color correction matrix can be downloaded to the camera.
A software tool to generate this is available with the Sapera processing applications, which
can be downloaded from the Teledyne DALSA web site (60 day free trial). You will require a
©
MacBeth chart with 4 x 6 color elements that you can scan past the camera to complete
the generation of the matrix.
Contact Teledyne DALSA's technical support for further details.
