OV9620/OV9120 DATASHEET Description
Applications
The OV9620 (color) and OV9120 (black and white) are highperformance 1.3 mega-pixel CameraChips for digital still image and video camera products.
. Digital Still Camera . PC Camera/Dual Mode . Video Conference . Machine Vision . Security Cameras . Biometrics
Both devices incorporate a 1280x1024(SXGA) image array and an on-chip 10-bit A/D converter capable of operating at up to 15 frames per second (FPS) with full resolution. Proprietary sensor technology utilizes advanced algorithms to cancel Fixed Pattern Noise (FPN), eliminate smearing, and drastically reduce blooming. The control registers allow for flexible control of timing, polarity, and CameraChip operation, which in turn allow the engineer a great deal of freedom in product design.
Features Optical Black Level Calibration Video or Snapshot Operations Programmable/Auto Exposure and Gain Control Programmable/Auto White Balance Control Horizontal & Vertical Sub-sampling (4:2 & 4:2) Programmable Image Windowing Variable Frame Rate Control On-Chip R/G/B Channel and Luminance Average Counter Internal/External Frame Synchronization SCCB Slave Interface Power on Reset and Power Down Mode
