ICX254AK
Diagonal 6mm (Type 1/3) CCD Image Sensor for NTSC Color Video Cameras
Description
The ICX254AK is an interline CCD solid-state
image sensor suitable for NTSC color video cameras
with a diagonal 6mm (Type 1/3) system. Compared
with the current product ICX054BK, basic
characteristics such as sensitivity, smear, dynamic
range and S/N are improved drastically through the
adoption of EXview HAD CCD
TM
technology.
This chip features a field period readout system and
an electronic shutter with variable charge-storage
time.
EXview HAD CCD
TM
has different spectral characteristics
from the current CCD.
