0.3MP VGA global shutter camera module OV7251 PRELIMINARY SPECIFICATION 1/7.5" CMOS VGA(640 x 480) image sensor with OmniPixel3-GS™ technology
The global shutter OV7251 camera module
The OV7251 (b&w) image sensors are low voltage, high performance 1/7.5 inch VGA CMOS image sensors that provide the functionality of a single VGA (640x480) camera using OmniPixel3-GS™ technology. They
provide full-frame, sub-sampled, and windowed 8/10-bit MIPI images via the control of the Serial Camera Control Bus
(SCCB) interface.
