Figure 27. Camera Module Block Diagram
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 0.35
μ
m 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.
