Description
The CH5101 is a single chip active pixel CMOS
monochrome video camera with digital video output in
several formats. Using sophisticated noise correction
circuitry to minimize fixed pattern noise and dark current
effects, the CH5101 provides a supurb quality picture in a
low cost device.
The CH5101 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 CH5101 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 CH5101
provides a low cost camera for the next generation
videophone, toy, and surveillance products.
