Mono 10
With the camera set to Mono 10, the pixel data output is 10 bit monochrome, unsigned char and unpacked type.
This type is divided into two bytes when 10 bit pixel data are stored in the frame buffer. 8 bits of pixel data will be
stored in Byte 0, 2 bits of pixel data will be stored in Byte 1, and the rest 6 bits will not be used.
Mono 10 Packed
With the camera set to Mono 10 Packed, the pixel data output is 10 bit monochrome, unsigned char and
GigE Vision-specific packed type.
This type is divided into three bytes when 20 bit pixel data are stored in the frame buffer. 8 bits of pixel data 0 will
be stored in Byte 0 and the rest 2 bits will be stored in Byte 1. Pixel Data 1 will be stored in Byte 2 and the rest 2
bits will be stored in Byte 1.
