6.5 Window Of Interest

The Window Of Interest (WOI) (also called region of interest) is defined as a rectangle

[x, y, w, h] where

X coordinate of upper left corner, starting with 0

Y coordinate of upper left corner, starting with 0

w Width of window

h Height of window

The rows and columns are counted beginning at 0, i.e. the last row and the last column have the address 1023.

Please note that certain restrictions apply to the start and stop value of horizontal direction (X):

If this is not the case, the LinePause value is automatically increased to avoid image artefacts.

The LineHopping attribute defines the line readout stepping. For example, a number of

2 skips all odd lines.

6.6 MROI / Mask Mode

When activated, the MROI mode applies a maximum number of 16 masks to the current window of interest. A mask is defined as a range of scan lines which are skipped and not read out which further speeds up the image acquisition. Note that mask windows may not overlap and are not checked for sanity. The parent window (Main WOI) must include the first mask, but may exclude trailing, unused masks.

A mask is defined by its Y start value and the height H. These are entered analogous to the main ROI.
