Registers R0x01 column start, R0x02 Row Start, R0x03 window height (row size), and
R0x04 Window Width (column size) control the size and starting coordinates of the
window.
The values programmed in the window height and width registers are the exact window
height and width out of the sensor. The window start value should never be set below
four.
To read out the dark rows set bit 6 of R0x0D. In addition, bit 7 of R0x0D can be used to
display the dark columns in the image.
Horizontal blanking and vertical blanking registers R0x05 and R0x06 respectively control
the blanking time in a row (horizontal blanking) and between frames (vertical blanking).
• Horizontal blanking is specified in terms of pixel clocks.
• Vertical blanking is specified in terms of numbers of rows.
The actual imager timing can be calculated using Table 4 on page 13 and Table 5 on
page 14 which describe “Row Timing and FRAME_VALID/LINE_VALID signals.” The
minimum number of vertical blank rows is 4.
This register (along with the window width and horizontal blanking registers) controls
the integration time for the pixels.
The actual total integration time,
Typically, the value of R0x0B (total shutter width) is limited to the number of rows per
frame (which includes vertical blanking rows), such that the frame rate is not affected by
the integration time. If R0x0B is increased beyond the total number of rows per frame, it
is required to add additional blanking rows using R0x06 as needed. A second constraint
is that
60Hz flicker, this means frame time must be a multiple of 1/120 of a second. Under 50Hz
flicker, frame time must be a multiple of 1/100 of a second.
t
The number of rows integration is equal to the result of automatic exposure control
(AEC) which may vary from frame to frame, or, if AEC is disabled, the value in R0x0B
Row time = (R0x04 + R0x05) master clock periods
Overhead = (R0x04 + R0x05 – 255) master clock periods
INT = (Number of rows of integration × row time) + Overhead, where:

INT must be adjusted to avoid banding in the image from light flicker. Under
