Horizontal and vertical binning can be controlled independently(e.g. this allows combinations such as 2v x 1h or 1v x 4h). The default value for the binning is 1x1.To enable binning, you must write a command (85h) to Register 2, followed by a data byte thatdefines how many horizontal and vertical pixels to bin.The binning command must be followed by a data byte where bits 0 through 2 (H nibble) definethe vertical binning mode and bits 4 through 6 (V nibble) define the horizontal binning mode. Bits3 and 7 are unused. Reference Table 13 for valid data bits. All invalid commands will default to1x1 binning.Example: Setting the camera to 2x2 binning modeH nibble = 2 = 010V nibble = 2 = 010∴ data byte = 0010 0010Command ValueBinary 1000 0101 0010 0010Hex 85h 22hunusedH nibbleV nibble
