[Capella Microsystem Inc.]

Description
CM3323 Color Sensor senses Red, Green, Blue and White light and incorporates photodiode, amplifiers and analog/digital circuits into a single chip using CMOS process. The active programmable color sensor interruption features offer the best utilization on the microcontroller. With the color sensor applied, the brightness and color temperature of backlight can be adjusted base on ambient light source that makes panel looks more comfortable for end user’s eyes. The adoption of Capella’s patented Filtron™ technology achieves the closest ambient light spectral sensitivity to real human eye responses.
