ICX074AK
Diagonal 8mm (Type 1/2) Progressive Scan CCD Image Sensor with Square Pixel for Color Video Cameras
Description
The ICX074AK is a diagonal 8mm (Type 1/2)
interline CCD solid-state image sensor with a
square pixel array which supports VGA format.
Progressive scan allows all pixels signals to be
output independently within approximately 1/60
second. This chip features an electronic shutter with
variable charge-storage time which makes it
possible to realize full-frame still image without a
mechanical shutter. High resolution and high color
reproductivity are achieved through the use of R, G,
B primary color mosaic filters.
Further, high sensitivity and low dark current are
achieved through the adoption of HAD (Hole-
Accumulation Diode) sensors.
This chip is suitable for image input and
processing applications.
