Description

The OV9625 (color) and OV9121 (black and white) are high-performance 1.3 mega-pixel CAMERACHIPS^TM for digital still image and video camera products.

OV9121 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 of OV9121 allow for flexible control of timing, polarity, and CameraChip operation, which, in turn, allows the engineer a great deal of freedom in product design.
