CMOS Block
This CMOS image sensor which consolidates sensor section and image process DSP consists of one chip. Each pixel 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).
Analogue pixel voltage data which is converted to digital colored image signal is finished using DSP. Those signals are sent out
as digital format 8 bit span YUV with PCLK, HD and VD 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.
Setting up of each chip register is set at I2C by CPU (IC101) on Main Board.
