: Horizontal effective image start position, 12 bits (write/read)

: Vertical effective image start position, 12 bits (write/read)

: Horizontal effective image size, 12 bits (write/read)

: Vertical effective image size, 12 bits (write/read)

: Horizontal direction pixel thinning rate, 3 bits (write/read)

: Vertical direction pixel thinning rate, 3 bits (write/read)

: Frame thinning rate, 4 bits (write/read)

: Data buffer X address, 8-pixel unit

: Data buffer Y address, 1- (or 8-) line unit

12 bits (write/read)

At a write, starts image capture when “1” is written, and stops forcibly when “0” is written.

At a read, “1” indicates capturing, and “0” indicates the completion of capture.

“0”: 1 frame capture

“1”: Continuous frame capture

“000”: 1/1, “001”: 1/2, “010”: 1/4, “011”: 1/8, “100”: 1/16

“0000”: 1/1, “0001”: 1/2, …, “1110”: 1/15, “1111”: 1/16
