Can anyone direct me on how to improve the quality of ICMDecompression?  I am decompressing MJPEG images from a network video camera.  The image looks good if I use NSImage to create an image and display it with ImageView.  But if I use an ICMDecompression Session and drawImage the image looks washed out.

I have tried setting kICMDecompressionSessionOptionsPropertyID_Accuracy with ICMDecompressionSessionOptionsSetProperty and it does not seem to do anything.  (I can see a difference with this in WackedTV using a miniDV camera)

BTW I am using GraphicsImportGetImageDescription() to create an ImageDescription fro the decompression session.

Thanks.
