8.15 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.
Embedded image values are those in effect at the end of shutter integration.
Each piece of information takes up 32-bits (4 bytes) of the image. When the camera is using an 8- bit pixel format , this
is 4 pixels worth of data.
The following frame-specific information can be provided:
• Timestamp
• Gain
• Exposure
• Brightness
• White Balance
• Frame counter
• Strobe Pattern counter
• GPIO pin state
• ROI position
If you turned on all possible options the first 40 bytes of image data would contain camera information in the following
format, when accessed using the FlyCapture 2 API:
(assuming unsigned char* data = rawImage.GetData(); and an Image object rawImage):
• data[0] = first byte of Timestamp data
• data[4] = first byte of Gain data
• data[24] = first byte of Frame Counter data
If only Exposure embedding were enabled, then the first 4 bytes of the image would contain Exposure information for
that image. Similarly, if only Brightness embedding were enabled, the first 4 bytes would contain Brightness
information.
For black and white cameras, white balance is still included, but no valid data is provided.
