HV7131RP
General Description
HV7131RP is a highly integrated single chip CMOS color image sensor implemented by proprietary
MagnaChip 0.30um CMOS sensor process realizing high sensitivity and wide dynamic range. Total
Pixel Array are 660x507 pixels. Each active pixel composed of 4 transistors has a micro-lens to
enhance sensitivity, and converts photon energy to analog pixel voltage. On-chip 10bit Analog to
Digital Converter (ADC) digitizes analog pixel voltage, and on-chip Correlated Double Sampling (CDS)
scheme reduces Fixed Pattern Noise (FPN) dramatically. General image processing functions such as
gamma correction, color interpolation, color correction, color space conversion, H/V Edge
Enhancement, Image Enhancement, auto exposure, and auto white balance are implemented to
diversify its applications, and various output formats are supported for the sensor to easily interface
with different video codec chips. The integration of sensor function and image processing functions
make HV7131RP especially very suitable for mobile imaging systems such as IMT-2000 phone’s video
part that requires very low power and system compactness.
