Description

The ICX228AK is an interline CCD solid-state image sensor suitable for NTSC color video cameras. Compared with the current product ICX208AK, smear characteristics are improved drastically and power consumption is reduced. High resolution is achieved through the use of Ye, Cy, Mg, and G complementary color mosaic filters. High sensitivity and high saturation signal are achieved by Super HAD CCD technology. This chip features a field period readout system and an electronic shutter with variable charge-storage time. The package is a 10mm-square 14-pin DIP (Plastic).

Application Scenarios

This interline CCD solid-state image sensor, ICX228AK, is mainly used in NTSC color video cameras. It is suitable for various environments and applications that require high sensitivity, high resolution, and low power consumption. Its anti-blooming characteristics make it ideal for capturing images with excellent picture quality and preventing overexposure in bright conditions. The continuous variable-speed shutter allows for flexibility in adjusting the exposure time to capture the desired image.
