1/4-inch, 5-megapixel soc image sensor optimized for high-volume mobile markets OV5640 5-megapixel product brief lead free available in a lead-free package the OV5640 delivers a complete 5-megapixel camera solution on a single chip, aimed at offering cost efficiencies that serve the high- volume autofocus (af) camera phone market. the system-on-a- chip (soc) sensor features omnivision's 1.4 micron omnibsi? backside illumination architecture to deliver excellent pixel performance and best-in-class low-light sensitivity, while enabling ultra compact camera module designs of 8.5 mm x 8.5 mm with <6 mm z-height. the OV5640 provides the full functionality of a complete camera, including anti-shake technology, af control, and mipi while being easier to tune then two-chip solutions, making it an ideal choice in terms of cost, time-to-market and ease of platform integration. the OV5640 enables 720p hd video at 60 frames per second (fps) and 1080p hd video at 30 fps with complete user control over formatting and output data transfer. the 720p/60 hd video is captured in full field of view (fov) with 2 x 2 binning, which doubles the sensitivity and improves the signal-to-noise ratio (snr). additionally, a unique post-binning re-sampling filter function removes zigzag artifacts around slant edges and minimizes spatial artifacts to deliver even sharper, crisper color images. to further improve camera performance and user experience, the OV5640 features an internal anti-shake engine for image stabilization, and it supports scalado? tagging for faster image preview and zoom. the OV5640 offers a digital video port (dvp) parallel interface and a high-speed dual lane mipi interface, supporting multiple output formats. an integrated jpeg compression engine simplifies data transfer for bandwidth-limited interfaces. the sensor's automatic image control functions include automatic exposure control (aec), automatic white balance (awb), automatic band filter (abf), 50/60 hz automatic luminance detection, and automatic black level calibration (ablc). the OV5640 delivers programmable controls for frame rate, aec/agc 16-zone size/position/weight control, mirror and flip, cropping, windowing, and panning. it also offers color saturation, hue, gamma, sharpness (edge enhancement), lens correction, defective pixel canceling, and noise canceling to improve image quality. find out more at www.ovt.com.
