6.18.1 ImageBLITZ® processing
When ImageBLITZ® is activated with :r7
h
[0] = 1:
1. Wait for an active edge on the EXP input.
2. The MC13xx exposes a line, that was chosen with :rC[9..0] and is called trigger line, for an
exposure time defined by :r2[9..0]. It compares the intensity of a group of 10 pixel along the
selected trigger line against an adjustable threshold (:rA
h
[7..0], Range: 255..0).
3. The number of exceedings (:rA
h
[8] = 0) or fall backs (:rA
h
[8] = 1), are counted, and the re-
sult is compared to a second threshold (:rB
h
[6..0], Range: 127..0).
4. Each time this threshold is exceeded (release condition); an “inhibit counter” (:rD
h
[9..0],
Range 1..255) is loaded.
5. The inhibit counter” :rD
h
[9..0] is counted down, each time the “release condition” was not
reached. Once this “inhibit counter” has expired, a new image is exposed and output.After
image is output, repeat at 1.
6.18.2 ImageBLITZ® programming
ImageBLITZ® is programmed by registers r8..rD
h
and activated with r7[0].
6.18.2.1 Address of trigger line
The register rC
h
determines the vertical position of the trigger line in the image.

... range 00h ...3ffh
Response: none
Example: :rc100

L
In pixelbinning mode the value of rC is internally
doubled. The value must not be higher than
1ffh/511.
6.18.2.2 Leftmost pixel of the trigger line
The value of register r8 / 10 is the number of the leftmost pixel in the trigger line.
