General Description  
Applications  
Digital still cameras  
PC camera/dual mode  
Video conference applications  
Machine vision  
Security cameras  
Biometrics  
The OV9625 (color) and OV9121 (black and white) are  
high-performance 1.3 mega-pixel CAMERACHIPS  
digital still image and video camera products.  
TM  
for  
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.
