the less the frame rate is. This control defines the frequency of polling the camera for its
image stream.
Decimation
Use the
Decimation
drop-down box to decimate (sub-sample) the picture by 2, 3, 4, 5,
6, 7 or 8. The decimation means excluding pixels and rows from the scan process (for
example, every second pixel and second row for the 1:2 decimation). This mode thus
allows viewing the picture at the higher frame rate.
The higher decimation can be used for preview, when 1600 x 1200 image can be
displayed as 800 x 600 with the frame rate two times higher.
Viewport
Viewport is a rectangular area of the sensor on which the image is scanned. It can have
variable size: from the full sensor field of view to the small area of 8 x 8 pixels. The
smaller vertical size (in lines) of the viewport, the faster the scan process and the higher
the frame rate is.
To change the viewport:
