BayerSensorAlignment
Purpose Specify sensor alignment for Bayer demosaicing
Description If the ReturnedColorSpace property is set to 'b ayer',thenImage
Acquisition Toolbo x will demosaic Bayer patterns returned by the
hardware. This color space setting w ill interpolat e Bayer patte r n
encoded images into standard RGB images. If your camera uses Bayer
filtering, the toolbox supports the Bayer pattern and can return color if
desired.
In order to perform the demosaicing, the toolbox needs to know the pixel
alignment of the sensor. T his is the order of the red, green, and blue
sensors and is normally specified by describing the four pixels in the
upper-left corner of the sensor. It is the band sensitivity alignment of
the pixels as interpreted by the camera’s internal hardware. You must
get this information from the camera’s documentation and then specify
the v alu e for the al ig nment, as described in the following table.
There are four possible sensor alignments.
