OV07141-C01A (B&W with micolens)

OV07141-P01A (B&W with micolens)

The OV7640 (color) and OV7141 (black and white)

that provide the full functionality of a single-chip VGA

(640 x 480) camera and image processor in a small

footprint

full-frame, sub-sampled or windowed 8-bit images in a

wide range of formats, controlled through OmniVision’s

Serial Camera Control Bus (SCCB) interface. The

OV7640/OV7141 sensor has an image array capable of

operating at up to 30 frames per second (fps) with

complete user control over image quality, formatting and

output data transfer. All required image processing

functions, including exposure control, gamma, white

balance, color saturation, hue control etc., are also

programmable through the SCCB interface. In addition,

OmniVision

technology to improve image quality by reducing or

eliminating common lighting/electrical sources of image

contamination such as fixed pattern noise, smearing,

blooming, etc. to produce a clean, fully stable color image.
