ICX452AQ
Diagonal 9.04mm (Type 1/1.8) Frame Readout CCD Image Sensor with a Square Pixel for Color Cameras
Description
The ICX452AQ 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.

Note) Blacked out portions in the diagram indicate pixels which are not read out.
1. Frame readout mode
In this mode, all pixel signals are divided into three fields and output.
All pixel signals are read out independently, making this mode suitable for high resolution image capturing.
2. High frame rate readout mode
Output is performed at 30 frames per second by reading out 4 pixels for every 18 vertical pixels and adding
2 pixels in the horizontal CCD.
The number of output lines is 218 lines.
This readout mode emphasizes processing speed over vertical resolution.
