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.
