Image Filters

Kernels
The camera has a selection of image filters that can be used to reduce the noise in an
image.
The options are: no filtering, 1 x 3, and 1 x 5 filter kernels. The 1 x 3 and 1 x 5 filter kernels
are ―weighted average‖ filters.
The 1 x 3 filter kernel uses 75% of the original pixel and 12.5% of the adjacent pixels.
The 1 x 5 filter kernel uses 50% of the original pixel and 12.5% of the adjacent two pixels
on both sides of the original pixel.

Image Filter Contrast Ratio
The image filter contrast ratio control is used to turn on the filter in an active image.
The control looks at the ratio between two adjacent pixels (prior to filter processing) and
determines the difference, or contrast, between those pixels. If the contrast ratio is greater
than the value set by the user then the filter automatically turns off for those two pixels. If
the contrast is below the set value then the pixels are filtered. A value of 0 will turn off the
filters for all pixels and a value of 1 will keep the filter on for all pixels.

Number of horizontal photo-sensitive cells to
combine together. This increases the
intensity of the pixels but reduces the
horizontal resolution.
Note: horizontal binning cannot be enabled if
the GreenOnly mode or RGBG8 mode is
selected.
Number of vertical photo-sensitive cells to
combine together. This increases the
intensity of the pixels but reduces the vertical
resolution of the image.
