Data Flow
[PC Scan]
1. An analog image data is output from CIS unit to IC503.
IC503 decode the analog data to digital data, and output to IC300.
Scanner I/F in IC300 process image data and store it in IC400
through SDRAM I/F.
Scanner I/F in IC300 process image data and store it in IC400
through SDRAM I/F.
2. If necessary, the data is compressed via DSP.
3. The data is output to PC through the USB I/F.
3. The data is output to PC through the USB I/F.
