OV9625 Color CMOS SXGA (1.3 MPixel) CAMERACHIPTM
OV9121 B&W CMOS SXGA (1.3 MPixel) CAMERACHIPTM
General Description
The OV9625 (color) and OV9121 (black and white) are
high-performance 1.3 mega-pixel CAMERACHIPSTM for
digital still image and video camera products.
Both devices incorporate a 1280 x 1024 (SXGA) image
array and an on-chip 10-bit A/D converter capable of
operating at up to 15 frames per second (fps) at full
resolution and an improved micro lens design to decrease
shading. 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, allows the engineer
a great deal of freedom in product design.
Features
• Optical Black Level Calibration (BLC)
• Improved micro lens design to decrease shading
• Video or snapshot operations
• Programmable/Auto Exposure and Gain Control
• Programmable/Auto White Balance Control
• Horizontal and vertical sub-sampling (4:2 and 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
Applications
• Digital still cameras
• PC camera/dual mode
• Video conference applications
• Machine vision
• Security cameras
• Biometrics
