Ai338
1/3 inch CCD Image Sensor for NTSC Camera
1.1 General Description
The Ai338 is a 380K pixels CCD area sensor
for NTSC 1/3 inch video cameras. Buried
photodiodes and micro lenses are adopted for
low noise, low smear and high sensitivity. A
chrominance signal is achieved by the adoption
of Yellow, Magenta, Cyan and Green
complementary color mosaic filters. This
product also has the features of strong anti-
blooming and electronic shutter with variable
charge-storage time.

3.3.4. Vertical transfer efficiency
1) Set 1.0 lx illumination condition, then measure the signal output.
2) Detect average value of horizontal last line in effective area ( V_EFF ).
3) Detect average value of horizontal first line in OB area ( V_OB ).
4) Detect average value of horizontal line in reference area ( V_REF ).
5) Detect Vertical transfer efficiency with the following formula
6) See figure 3 below for the Test area.
