HV7161SPA2
CMOS Image Sensor
With Image Signal Processing
General Description
1.3Mega pixel CIS is a highly integrated single chip CMOS color image sensor implemented by
proprietary MagnaChip 0.18um CMOS sensor process realizing high sensitivity and wide dynamic
range. Total active pixel array is 1.3Mega size. Each active pixel composed of 4 transistors has a
micro-lens to enhance sensitivity, and converts photon energy to analog pixel voltage. On-chip
11bit 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 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 1.3Mega pixel CIS especially very suitable
for mobile imaging systems such as digital still camera, PC input camera and IMT-2000 phone’s
video part that requires very low power and system compactness.
