Windowing
For certain applications it may not be desirable to acquire full 640x512 frames. The Wildcat
offers the capability to set a certain window or Region Of Interest (ROI) for the acquired
frames.
Windowing options can be found under
Image format control
. The
Width
and
Height
settings define the width and height of the window. The
Offset X
and
Offset Y
settings
indicate the coordinates of the top-left pixel of the window. The coordinates of the top-left
pixel in the full image are (0, 0).
Windowing has a minimal granularity of 8 pixels in both dimensions. These settings will
automatically adjust to the nearest valid values that are smaller than the window entered.
Sensor dimensions and full image are also noted in the user interface.
Windowing the sensor may significantly reduce readout time, as less pixels must be
sampled and processed by the camera for each frame.
Note that these settings are only accessible when image acquisition is stopped.
The corresponding camera registers may be found in Chapter 9.1.3.
