1 / 43 page  Version 1.6, February 28, 2006 Proprietary to OmniVision Technologies 1 Advanced Information Preliminary Datasheet OV2640 Color CMOS UXGA (2.0 MegaPixel) CAMERACHIPTM Omni ision ® with OmniPixel2TM Technology General Description The OV2640 CAMERACHIPTM is a low voltage CMOS image sensor that provides the full functionality of a single-chip UXGA (1632x1232) camera and image processor in a small footprint package. The OV2640 provides full-frame, sub-sampled, scaled or windowed 8-bit/10-bit images in a wide range of formats, controlled through the Serial Camera Control Bus (SCCB) interface. This product has an image array capable of operating at up to 15 frames per second (fps) in UXGA resolution 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, white pixel canceling, noise canceling, and more, are also programmable through the SCCB interface. The OV2640 also includes a compression engine for increased processing power. In addition, OmniVision CAMERACHIPS use proprietary sensor technology to improve image quality by reducing or eliminating common lighting/electrical sources of image contamination, such as fixed pattern noise, smearing, etc., to produce a clean, fully stable color image. Features • High sensitivity for low-light operation • Low operating voltage for embedded portable apps • Standard SCCB interface • Output support for Raw RGB, RGB (RGB565/555), GRB422, YUV (422/420) and YCbCr (4:2:2) formats • Supports image sizes: UXGA, SXGA, SVGA, and any size scaling down from SXGA to 40x30 •VarioPixel® method for sub-sampling • Automatic image control functions including Automatic Exposure Control (AEC), Automatic Gain Control (AGC), Automatic White Balance (AWB), Automatic Band Filter (ABF), and Automatic Black-Level Calibration (ABLC) • Image quality controls including color saturation, gamma, sharpness (edge enhancement), lens correction, white pixel canceling, noise canceling, and 50/60 Hz luminance detection • Line optical black level output capability • Video or snapshot operation • Zooming, panning, and windowing functions • Internal/external frame synchronization • Variable frame rate control • Supports LED and flash strobe mode • Supports scaling • Supports compression • Embedded microcontroller Ordering Information Pb Note: The OV2640 uses a lead-free package.
