Chunk Data Function
The Chunk Data function adds camera configuration information to the image data that is output from
the camera.
Embedding camera configuration information in the image data allows you to use the serial number of
the camera as a search key and find specific image data from among large volumes of image data. In
addition, when images are shot with a single camera in sequence under multiple setting conditions,
you can search for images by their setting conditions.
The following information can be added to image data as chunk data.
