CCD Area Image Sensor
MW3795H, MW3795S
11mm (2/3 inch) CCD Area Image Sensors for HDTV
s
Overview
The MW3795H and MW3795S are 11mm (2/3 inch) Frame Interline
Transfer CCD (FIT-CCD) solid state image sensor device.
This device uses photodiodes in the optoelectric conversion section
and CCDs for signal read out. The electronic shutter function has
made possible an exposure time of 1/10000 seconds. Further, this
device has the features of high sensitivity, low noise, broad dynamic
range, and low smear.
This device has a total of 1410K pixels (1326 horizontal
×
1045
vertical) and provides stable and clear images with a resolution of 900
horizontal TV-lines and 730 vertical TV-lines.

Note 1) The standard light input is the one when the exposure is done at an aperture of F/11 using a light source of 2856K and
920nt, and placing a color temperature conversion filter LB-40 (t=2.5mm, Hoya) and an IR cutting filter CAW-500
(t=2.5mm, Hoya) in the light path.
Note 2) V
Sub
shall be adjusted so that the smears appearing at the top and the bottom of the imaged area (the top and bottom
smears) are equal when a target is imaged at the center of the screen with 3/10V of the specified exposure and the readout
pulse is turned OFF.
*1
V
Sub(2)
is the applied voltage during frame transfer.
V
Sub(3)
is the applied voltage during electronic shutter operation.
