Integrated CMOS Image Sensor
with Digital Output and
Timing Controller
(352 x 288 Resolution)
Technical Data
Description
A CMOS active pixel sensor (APS) array, available in both color and
monochrome, containing an array of 352 x 288 pixels. This product offers
excellent image quality with low power consumption, low dark current,
high sensitivity and anti-blooming characteristics. High temperature
tolerant color filter array enables machine solderability. Operating from a
single bias voltage, this sensor simplifies overall system design.
Features
· CIF (352 x 288 pixels) array size in two options. Color or
monochrome versions available
· Random access and windowing capability to zoom to any sized
window on 4 x 4 pixel boundaries
· Panning capability to any location within the sensor array
· Video rates up to 45 frames per second for CIF window size
· 4:1 sub-sampling capability of viewing window, providing up to
162 frames per second
· Still image capability
· Mechanical shutter and flash trigger
· Accumulation mode to aid in determining proper exposure time
· Low power/standby modes
· Machine solderable, high temperature tolerant color filter array
· Two 10-bit internal successive-approximation ADCs
· Automatic subtraction of column fixed pattern noise
· Color array using RGB Bayer filter pattern
· Integrated timing controller simplifying system design
· Digital output via l0-bit synchronous parallel interface
· Programmable features include: window size, integration time,
gain control (separate for red, green and blue), data rate,
interface timing, interrupt control, operation modes, selection of
8 or 10 bit output, drive level of output pads, access to status
signals via a synchronous serial or asynchronous UART interface
