Technical content

The OV2655 is a single-chip, high-performance 2 megapixel CMOS CameraChip sensor with a 1/5-inch optical format. The OV2655 is based on OmniVision’s 1.75 micron OmniPixel3-HS™ architecture which uses Ultra Low Stack Height (ULSH) pixels to acheive industry- leading low-light sensitivity of 1030 mV/(Lux-sec), which is vital for high frame rate video applications. The small form factor of the OV2655 also makes it possible for it to fit in a 6.5 x 6.5 mm camera module. The OV2655 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 available in a lead-free package OV2655 2 megapixel high sensitivity 1/5-inch 2 megapixel CameraChip™ sensor product brief high-speed serial interface. The DVP can also be used for input from an external secondary camera, enabling the advanced ISP of the OV2655 to be used by the secondary camera with continued output through the MIPI interface. Despite its small form factor, the OV2655 has an advanced image signal processor embedded with all functions required by a high-performance camera. For identification purposes, the OV2655 includes one-time programmable (OTP) memory.
