Could you provide more details, please ? The 12 bit resolution for each of 3 RGB color component is not enough ? How fast do you change the detectable object ? How is the light source ? What is the color range needed to detect ? Sorry for so much questions, but in last years I done a lot of test devices for Sony Bravia TV boards, where I detected the LEDs color, and I had to solve a lot of torubble around ambient light, etc., and I thing that these information are necessary to start similar project. Regards Zoltan P.S. Today I have got again a 6 LED/board color detection. I have designed an aprox. 5*8cm board with detectors and microcontroller which are pressed manually (pins contacts) to the tested pcb and switching on the LEDs and measuring the color of each one and make a decision PASS/FAIL indicating with a Green LED. If you want I can send you pictures about the proto and 2 weeks later about the final version.

hey, there is an easier way to do it : A webcam and a small laptop like the Asus eee-pc and a capture software... in any case, 500 different color is too much to guarantee a 100% rate recognition. at least, you need to integrate a lightening device (LEDs or Halogen) to always acquire color in the same conditions and put shades to shield against ambient daylight influence. For just the software, your budget is too high, I'll do it for $400 with the TWAIN API. Think about it : a four digits display is expensive. So are the chips to control it. To manage stored colors, you need flash or CMOS ram. Using existing standard hardware is cheaper.
