GENERAL DESCRIPTION
The VV5430 is a highly-integrated VLSI
camera device based on VISION’s unique
CMOS sensor technology. It is suitable for
applications requiring minimum external
circuitry, digitisation of the video signal or
external microprocessor control.
The device incorporates a 388 x 295 pixel
image sensor and all the necessary support
circuits to generate composite video into a 75Ω
load. Additional control signals support pixel
locked digitisation of the video signal.
A bi-directional serial interface and internal
register set allow full control and monitoring of
all camera functions. Automatic control of
exposure, gain and black level give a wide
range of operating conditions. All major control
functions are pin selectable giving maximum
flexibility with ease of use.
The VV5430 offers a complete camera system
ideally suited for integration into digital imaging
systems.
