Technical content

The OV3642 is the most advanced 1/4-inch, 3 megapixel SOC CameraChip sensor on the market today, both in terms of pixel quality as well as the new embedded TrueFocus ISP (image signal processing). Featuring OmniVision's high sensitivity 1.75 micron OmniPixel3-HS™ architecture, the OV3642 achieves a sensitivity of 960mV/(Lux-sec), delivering unparalleled low-light performance, which is crucial for all new high frame rate video applications and taking pictures without a flash. The embedded TrueFocus ISP (image signal processing) provides all functionality of a complete camera on a single chip, and features extended depth of field (EDoF) capabilities. The unique TrueFocus capabilities can be used with either wave front coded (WFC) lenses as well as standard traditional lenses, generating sharper and clearer images and videos to give the ultimate imaging experience for all camera phone applications. The OV3642 has an embedded microcontroller to support an internal auto focus engine, a programmable general available in a lead-free package OV3642 3 megapixel 1/4-inch, 3 megapixel CameraChip™ sensor with embedded TrueFocus™ technology product brief purpose I/O for external auto focus control, and an internal anti-shake engine for image stabilization. It uses proprietary sensor technology to improve image quality by reducing or eliminating common lighting and/or electrical sources of image contamination to produce a clean, fully stable, color image. All required image processing functions are programmable through the SCCB interface, MIPI interface or the integrated microcontroller. The OV3642 image array operates at up to 15 frames per second (fps) in full resolution (QXGA) transferred over a two-lane MIPI interface, or a traditional digital video port (DVP). The sensor contains an integrated JPEG compression engine, simplifying bandwidth limited interfaces. The OV3642's advanced TrueFocus ISP can also be used by an external secondary camera via its DVP while providing continued output through the MIPI interface. With all its added capabilities, the OV3642 still fits in a standard 8.5 x 8.5mm socket!
