IMAGE_SIZE
Width [0-15]
Width of requested image region (pixels)
Width = Hunit * n2

A.3.2.2 COLOR_CODING_ID and COLOR_CODING_INQ
The COLOR_CODING_INQ register describes the color-coding capability of the system. Each coding scheme has its
own ID number. The required color-coding scheme must be set to COLOR_CODING_ID register as the ID number.

Format:
A.3.2.3 PACKET_PARA_INQ, BYTE_PER_PACKET, and PACKET_PER_FRAME
If the Presence bit in the VALUE_ SETTING register (page 148) is zero, values of these fields will be updated by writing
the new value to the IMAGE_POSITION, IMAGE_SIZE (page 145) and COLOR_CODING_ID (page 146) registers with the
value of the ISO_Speed register (page 91).
First, the ISO_Speed register must be written. Then the IMAGE_ POSITION, IMAGE_ SIZE and COLOR_CODING_ID
registers should be updated.
If the Presence bit in the VALUE_SETTING register is one, the values of these fields will be updated by writing one to
the Setting_1 bit in the VALUE_SETTING register. If the ErrorFlag_1 bit is zero after the Setting_1 bit returns to zero,
the values of these fields are valid.
