DESCRIPTION
HB7122B is a highly integrated single chip CMOS B/W image sensor using Hyundai 0.5um CMOS process developed for image application to realize high efficiency photo sensor. The sensor has 414X314 pixels total, and 400X300 pixels effective. Each pixel is high photo sensitive, small size active pixel element that converts photons to analog voltage signal. The sensor has three on-chip 8 bit Digital to Analog Convert (DAC) and 414 comparators to digitize the pixel output. The three on-chip 8 bit DAC can be used for independent gain control. Hyundai proprietary on-chip Correlated Double Sampling (CDS) circuit can reduce Fixed Pattern Noise (FPN) dramatically. The whole 8 bit digital B/W raw data is directly available on the package pins and just a few control signals are needed for whole chip control, so it is very ease to configure a system using the sensor.
