HV7131GP

HV7131GP is a highly integrated single chip CMOS color image sensor implemented by proprietary MagnaChip 0.35um CMOS sensor process realizing high sensitivity and wide dynamic range. Total pixel array size is 652x492, and 652x488 pixels are active. 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, 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 HV7131GP especially very suitable for mobile imaging systems such as IMT-2000 phone's video part that requires very low power and system compactness.
