B/W Camera Module
General Description
This is a family of products based on the most
advance CMOS mixed signal technology. It inte-
grates image array, signal processing, timing and
control circuitry, all on a single chip, enabling all
aspects of B/W video camera applications. It is
ideal for applications requiring a small footprint,
low power and low cost.
