ICX274AQ
20 pin DIP (Plastic)
Description
The ICX274AQ is a diagonal 8.923mm (Type 1/1.8)
interline CCD solid-state image sensor with a square
pixel array and 2.01M effective pixels. Progressive
scan allows all pixels' signals to be output
independently within approximately 1/15 second,
and output is also possible using various addition
and pulse elimination methods. This chip features an
electronic shutter with variable charge-storage time
which makes it possible to realize full-frame still
images without a mechanical shutter. High resolution
and high color reproductivity are achieved through
the use of R, G, B primary color mosaic filters as the
color filters. Further, high sensitivity and low dark
current are achieved through the adoption of Super
HAD CCD technology.
This chip is suitable for applications such as
electronic still cameras, PC input cameras, etc.
