HV7131B

HV7131B is a highly integrated single chip CMOS color image sensor using Hyundai 0.5um CMOS process developed for image application to realize high efficiency R/G/B photo sensor. The sensor has 648X488 pixel array, and in general color interpolation method using 3x3 spatial mask with window size 642X482 pixels may be used for VGA(640X480) display mode. Each compact active pixel element has high photo-sensitivity and converts photon energy to analog voltage signal. The sensor HV7131B has three on-chip 8 bit Digital to Analog Convert (DAC) and 648 comparators to digitize the pixel output. The three on-chip 8 bit DAC can be used for independent R/G/B gain control. Hyundai proprietary on-chip Correlated Double Sampling (CDS) circuit can reduce Fixed Pattern Noise (FPN) dramatically. The whole 8 bit digital color raw data is directly available on the package pins and just a few control signals are needed for whole chip control so that it is very easy to configure CMOS imaging system.
