CMOS Image Sensors

The company has released two additions to its line of Digital Science image sensors, the KAC-0310 VGA sensor and the KAC-1310 Megapixel sensor, both of which are based on CMOS technology.

The VGA CMOS sensor is a 640 x 480 pixel array in a 1/3" optical format using a 7.8 micron pinned photodiode active pixel structure. It incorporates "global shutter" technology, which reduces image blur by simultaneously exposing the entire pixel array rather than sequencing the exposure line by line. The image size is fully programmable to a user-defined window of interest and allows sub-sampling to provide the higher frame rates needed for auto-exposure and auto-focus functions. Housed in a 48 pin ceramic LCC package, it operates with a single 3.3V power supply and requires a single master clock to operate.

The 1.3 megapixel CMOS sensor shares many features of the KAC-0310. It is a 1280 x 1024 pixel array in a half-inch optical format using a 6 micron pinned photodiode pixel structure. The sensor output is 8 or 10 digital bits and it supports both progressive or interlace scan modes. The chip is in a 48-pin ceramic LCC package.
