Technical content

The OV3640 is a feature-rich, high-performance

3.1 Megapixel CMOS CameraChip™ sensor in a

1/4 inch optical format. It is based on OmniVision's new 1.75μm OmniPixel3™ architecture with ultra low stack height (ULSH) for excellent low light sensitivity (500mV/lux-sec) and significantly improved noise and dynamic range (65dB). The highly integrated OV3640 incorporates an extremely advanced Image Signal Processor (ISP) with new features such as an advanced image stabilization/anti-shake (AS) engine that requires no external components. An embedded microcontroller supports the internal auto focus (AF) engine and the programmable general purpose I/O modules enable external auto focus control. available in a lead-free package OV3640 3.1 Megapixel 1/4-inch, high-performance 3 Megapixel CameraChip™ sensor with image stabilization and MIPI product brief The OV3640's image array operates at up to 15 frames per second (fps) in full 3-megapixel resolution (QXGA) transferred over a two lane MIPI interface or a traditional digital video port (DVP). The sensor also contains an integrated compression engine (JPEG), simplifying bandwidth limited interfaces. The fully integrated and feature-rich OV3640 is small enough to fit standard 8 x 8 mm fixed focus sockets as well as 8.5 x 8.5mm AF sockets, making it ideal for drop-in upgrades of existing camera modules used in existing lower mega-pixel camera phone designs. The OV3640's ISP can also be used by an external secondary camera via its DVP while providing continued output through the MIPI interface for the primary camera. For identification purposes, the OV3640 also includes a one time programmable (OTP) memory. All required image processing functions are programmable through the SCCB interface or the integrated micro-controller.
