The Camera module is fully functional camera module with embedded lens. A low-noise low-power
color CMOS image sensor, and an image signal processor, produce high-quality digital video output
including CCIR656 format with maximum 30 frames per second for full frame readout. The CMOS
image sensor, fabricated by SAMSUNG 0.35μm CMOS image sensor process technology which is
dedicated to higher-sensitivity and lower-dark level compared to standard CMOS process technology
and on-chip CDS and 10-bit column ADC circuit makes high signal-to-noise ratio with low power
consumption. The image sensor, signal processor and some passive components are packed with
IR-cut filter and lens units to have very small volume of whole camera system. It needs only 2.8V
single power supply and a main clock supplied to operate. All the function can be controlled by control
register setting through the standard 2-wire serial interface.
