7.13 Embedded Image Information
This setting controls the frame-specific information that is embedded into the first several pixels of the image. The first
byte of embedded image data starts at pixel 0,0 (column 0, row 0) and continues in the first row of the image data: (1,
0), (2,0), and so forth. Users using color cameras that perform Bayer color processing on the computer must extract
the value from the non-color processed image in order for the data to be valid.
Each piece of information takes up 32-bits (4 bytes) of the image. When the camera is operating in Y8 (8bits/pixel)
mode, this is therefore 4 pixels worth of data.
The following frame-specific information can be provided:
