Mode 0
Mode 0 allows only for specifying a region of interest, and does not perform any binning. This mode uses a faster pixel
clock compared to Mode 7, which can result in faster frame rates when ROI height is reduced.
Mode 1
Mode 1 implements 2X vertical and 2X horizontal additive binning. On color models, both horizontal and vertical binning
are performed as subsampling on the FPGA of the camera. In Mono, YUV and RGB color encoding formats, subsampling
occurs after color processing. On monochrome models, vertical binning is performed on the sensor, and horizontal
binning is performed on the FPGA. This mode results in a resolution that is both half the width and half the height of the
original image. Mode 1 may result in an increase in brightness and improved signal-to-noise ratio, however no frame
rate increase is achieved.
Mode 4
Mode 4 implements 2X vertical binning and 2X horizontal subsampling, and is available on color models only. Horizontal
subsampling is performed prior to color processing. Although image quality may be poorer than in Mode 1, a frame rate
increase is possible in this mode.
Mode 5
Mode 5 implements a combination of 4X horizontal and 4X vertical additive binning, resulting in a resolution that is both
one quarter the width and one quarter the height of the original image. In color models, all binning is performed after
the analog to digital conversion. In monochrome models, vertical binning is performed before the analog to digital
conversion, while horizontal binning is performed after the conversion to digital. Mode 5 may result in an increase in
brightness and improved signal- to-noise ratio. On monochrome models frame rates increase; however, on color
models, no frame rate increase is achieved.
Mode 6
Mode 6 implements a combination of 4X horizontal and 4X vertical binning. This mode is available on color models only,
and produces only monochrome output. Vertical binning is performed prior to color processing, and horizontal binning
