IMAGE AND DATA FORMATTING
NOTE: Only even values are expected to be entered at the ROI command.
The actual Region of Interest can be read back from the camera.
Command syntax: ROI?
Reply message: x;y;w;h
Where x, y, w and h are representing the values as described above
NOTE: Selecting a Region of Interest can be performed together with Burst Mode. In doing so, the
amount of images stored im memory increases relative to full image Burst Mode.
NOTE: ROI0;0;max. image width;max. image height disables the selected ROI.
Burst mode (optional) 8.4
The camera can be equipped with a ringbuffer memory. This memory can be used to temporarily delay
the output of the images when the camera is operated in control mode MO1. Acquisition and readout
are decoupled and may take place asynchronously when using Burst Mode. Not that Burst mode does
not increase the maximum framespeed, because the maximum frame speed is determined by sensor
characteristics. A predefined number of images in the buffer will be released at request.
Write images to memory
Read images from memory
Circular representation of the ringbuffer memory Figure 8.1:
The memory size is limited. Table 8.4 shows an overview of the number of images that can be stored
at full resolution. When using Region of Interest, the number of images increases, depending on the
size of the ROI.
