Description
OV7670 VGA Camera Module
The compact OV7670 camera module operates at low voltage and integrates VGA image-sensor and image-processing functions. Through the SCCB control bus, it can output full or subsampled frames with 8-bit data. The source lists up to 30 frames per second at 640 × 480 VGA. Image quality, data format and transmission mode can be configured; processing settings such as gamma, white balance and saturation are programmable over SCCB.
