3.10.2 Controls
Data00, Data01, Data02, Data03
Data00 to Data03 can be used to store custom data in the non-volatile memory
of the camera. This preserves the data for later use, even if the camera power
gets switched off.

3.11 ImageBlitz
3.11.1 Overview
The ImageBLITZ is a camera internal trigger unit that generates trigger pulses
in dependency of changes in a predefined area (ROI) of the camera sensor. At
a user defined time the current content of the area is saved and subsequently
compared with the same area in each new captured image for trigger gen-
eration. The trigger pulse is used to stop cyclic recording in the same manner
as described by the external trigger feature.
Size and position of the ROI can be freely defined within the sensor area but
the total number of pixels within the trigger area may not exceed 20480 pixels.
The trigger condition within the area is defined by a threshold for the amount
of changes in the brightness of a pixel and the number of pixels (Release
Condition) that have to change to release the trigger.
The pixels in the ROI are sub-packed to sets of 10 pixels. If one or more pixel in
a set exceeds the threshold a counter is incremented by one. If the counter
exceeds the release condition a trigger signal is generated. The counter will be
set to 0 for each new frame captured by the camera.
To ease the positioning of the ImageBLITZ area and the definition of the
threshold and release condition, the upper and lower border of the ROI can be
displayed as dotted lines in the captured images if the camera is in live mode.
To visualize the trigger point, the dotted lines gets inverted each time the trig-
ger releases.
