With the aforementioned flexible windowing capability of the sensor, the user is able to
read out different resolution formats from default of QXGA to UXGA, SXGA, XGA, SVGA,
VGA, CIF, QVGA, QCIF, etc. Below are some examples of programmable register settings
to obtain the estimated frame rates for the desired formats.
The user can change the values of R0x05 and R0x06 to obtain different frame rates. The
field of view of the image is reduced since the programmed settings effectively reduce
the read out window to the specified settings without skipping any rows or columns.
If the user only changes the register settings mentioned above without changing the row
and column start address, the read out window would start from that coordinate. To read
out the center of the image or any portion that is desired, the user would need to
program R0x01 and R0x02, thus performing electronic panning.
To maintain the same field of view while reducing the read out resolution, the user
would need to perform row and column skip. For example, if the desired read out resolu-
tion needs to be XGA (1,024H x 7,68V) instead of QXGA (2,048H x 1,536V). To maintain
the same field of view, the user can select column skip 2X and row skip 2X modes. This
effectively reduces the horizontal and vertical resolution by 2X for a factor of 4X reduc-
tion in overall number of pixels that are read out.
To perform this read out mode, the user would need to set the following:
