DESCRIPTION
PRELIMINARY
HV7131B
CMOS IMAGE SENSOR
With 8-bit ADC
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 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.
