LC822152
Built-in I2C master for CCD/CMOS module control. Without paying attention to the
I2C from the CPU, it is accessible to the CCD/CMOS module as well as the normal
register (write/read).
CCD output is a VGA size (640×480). The output is reduced/cropped to meet the LCD
display range with a scaler. Low-pass filter and enhancer are equipped.
The YUV422/YUV420 image data is compressed into JPEG code, and the JPEG code
data is expanded to the YUV422/YUV420 image data.
It performs thinning out, scaling down and cropping the LCD output images to an
image size of maximum 40×40.
LSI includes PLL and it multiplies the clock input from outside to make a main clock.
It divides this multiplied frequency to output to CCD/CMOS module as the clock.
