13.1.3. Camera Block
<Basic Circuit Operation>
This CMOS image sensor which consolidates sensor section and image process DSP by the
0.35umCMOS process consists of one chip. Each pixel which consists of four transistors has a micro
lens for increased sensibility. It changes optical energy to analogue voltage. After that, analogue pixel
voltage is converted into digital using the 10 bit AD Converter (ADC). At that time, Correlated Double
Sampling (CDS) dramatically decreases Formulaic Pattern Noise (FPN).
Analogue pixel voltage data which is converted to digital is finished using Gammacorrection, Color
Correction and Color Space Conversion. Those signals are sent out as digital format 8bit span Y/UV
with PCLK, Hsync and Vsync signals as a timing interface. In addition, the Image Processing Function
of AE (Auto Iris) and AWB (Auto White Balance) is installed and it is automatically operated following an
algorithm in the chip.
Exposure control (Auto Iris) is adjusted by shutter speed.
Setting up of each chip register is set at I2C (IC701:22/23 pin) by CPU (IC101) on Main Board.
