The OV2650 is a single-chip, high-performance

2 Megapixel CMOS CameraChip sensor with a

1/5” optical format. The OV2650 is based on OmniVision’s new 1.75 μm OmniPixel3™ architecture which uses Ultra Low Stack Height (ULSH) pixels that allows for improved low light sensitivity (520 mV/lux-sec). This new pixel architecture also makes it possible for the OV2650 to fit in a 6.5 x 6.5 mm camera module. Even with such a small footprint, the OV2650 is a feature-rich device that includes an advanced Image Signal Processor (ISP) and several new innovative features, such as image stabilization (anti-shake) and HDR mode. available in a lead-free package OV2650 2 Megapixel ultra small 1/5” 2 Megapixel CameraChip™ sensor with High Dynamic Range (HDR) and anti-shake functionality product brief The HDR mode of the OV2650 has a unique feature that enables it to increase the dynamic range from 65 dB in full resolution to about 85 dB in half resolution, a useful function for video capturing. The OV2650 operates at up to 15 frames per second (fps) in full resolution and 30 fps in SVGA mode. The captured data can be transferred either by a standard parallel digital video port (DVP) or by a single-lane MIPI high-speed serial interface. The DVP can also be used for input from an external secondary camera, enabling the advanced ISP of the OV2650 to be used by the secondary camera with continued output through the MIPI interface. All required image processing functions are programmable through the Serial Camera Control Bus (SCCB) interface. For identification purposes, the OV2650 includes a one-time programmable (OTP) memory.
