6.7 Smart Features on the A102f
6.7.1 Extended Data Stream
The extended data stream feature has two functions:
• When it is enabled, information such as image height, image width, and AOI size is added to
the basic pixel data for each image.
• It must be enabled before you can use any other smart feature that adds information to the
image data stream.
With the extended data stream feature enabled, the basic pixel data for each image and the added
information such as the image height and width are included in an “extended data chunk”. Refer
to the extended data chunk layout below for a complete description of the information included in
the extended data chunk.

The extended data stream feature must be enabled in order to use any of the other
smart feature that adds information to the image data stream. Disabling the extended
data stream feature switches off all smart features that add information to the image
data stream.
The extended data stream feature and any other smart features which add informa-
tion to the image data stream will only work when the camera is set for video format 7.
