Chrontel CH5001A
The CH5001 is a single chip active pixel CMOS color video camera with digital video output in several formats. The CH5001 uses a proprietary autoshutter algorithm to dynamically control the shutter time, analog gain, and black clamp level, providing optimum picture and contrast under all lighting conditions. The CH5001 also incorporates extensive on-chip programmable digital signal processing to maximize the usefulness of the device in processor driven applications.FEATURES

DESCRIPTION
Using sophisticated noise correction circuitry to minimize fixed pattern noise and dark current effects, the CH5001 provides a supurb quality picture in a low cost device. This includes 16 programmable zones for backlight compensation, allowing the user to adjust the image to their unique lighting environment. Additionally, at power-up the backlight compensation zone, power-up condition, and direct A/D output modes are selectable without IIC control by using the PUD pins. Requiring a minimum of parts for operation, the CH5001 provides a low cost camera for the next generation video conferencing, videophone, and surveillance products.
