Diagonal 6mm (Type 1/3) CCD Image Sensor for PAL Color Video Cameras
Description
The ICX255AK is an interline CCD solid-state image sensor suitable for PAL color video cameras with a diagonal 6mm (Type1/3) system. Compared with the current product ICX055BK, basic characteristics such as sensitivity, smear, dynamic range and S/N are improved drastically through the adoption of EXview HAD CCDTM technology.
This chip features a field period readout system and an electronic shutter with variable charge-storage time.
EXview HAD CCDTM has different spectral characteristics from the current CCD.
Features
• High sensitivity (+6dB compared with the ICX055BK)
• Low smear (–20dB compared with the ICX055BK)
• High D range (+3dB compared with the ICX055BK)
• High SNR(Signal to Noise Ratio)
• Low dark current
• Excellent antiblooming characteristics
• Ye, Cy, Mg, and G complementary color mosaic filters on chip
• Continuous variable-speed shutter
• No voltage adjustment (Reset gate and substrate bias are not adjusted.)
• Reset gate: 5V drive
• Horizontal register: 5V drive
