Description
The CH5001 is a single chip active pixel CMOS color
video camera with digital video output in several formats.
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.
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. 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.
