ICX452AQF
Diagonal 9.04mm (Type 1/1.8) Frame Readout CCD Image Sensor with a Square Pixel for Color Cameras
Description
The ICX452AQF is a diagonal 9.04mm (Type 1/1.8)
interline CCD solid-state image sensor with a square
pixel array and 5.13M effective pixels. Adoption of a
3-field readout system ensures small size and high
performance. This chip features an electronic shutter
with variable charge-storage time.
R, G, B primary color mosaic filters are used as
the color filters, and at the same time high sensitivity
and low dark current are achieved through the
adoption of Super HAD CCD technology.
This chip is suitable for applications such as image
input of high resolution digital still camera and
multimedia system, etc.
