KC74125B 1/4 INCH CCD IMAGE SENSOR FOR EIA CAMERA
1
INTRODUCTION
The KC74125B is an interline transfer CCD area image
sensor developed for EIA 1/4 inch optical format video
cameras, surveillance cameras, object detectors and image
pattern recognizers. High sensitivity is achieved through on-
chip micro lenses and HAD (Hole Accumulated Diode)
photosensors.
This chip features a field integration read out system and an
electronic shutter with variable charge storage time.
