Binning

The VX6953CB also has a binning mode that offers a reduced size full field of view image.

The binning mode averages row and column pixel data.

The binning mode results in a reduced number of lines and so can be used to give a higher

image frame rate. Compared to subsampling, binning makes use of the light gathered from

the whole pixel array and it results in higher image quality.

The binning mode will scale by 2 x 2 in the X and Y directions.

Entering and exiting binning mode may or may not be performed when the sensor is in

software standby.

Table 33 summarizes the register settings for each of the binning modes. Refer to the

personality file for further image quality settings.
