Image Superimposition
The user has the capabilities to superimpose over a live image the following
test patterns. The user can change the brightness of the superimposed image
from black (invisible) to white “
Crosshair
” – Crosshair watermark (2 pixels
and 2 lines thickness) indicating the absolute image center of the image.
-
“
H & V Lines
” – A pair of Horizontal and Vertical lines can be positioned
in the image. The user can enable the lines in horizontal, vertical or both
directions, and to position them at any pixel/line in the image.
Since the H
& V lines can be used as a measuring tool, the pixel and line positions are
referenced to the CCD pixels and lines, not to the image pixels and lines
.
The spacing between the lines can be displayed in:
1.
Pixels
- Natively, the spacing between the lines is shown in pixels
2.
Metrical units
- In addition, the user can use these lines as a measuring
tool. The user can apply a scale coefficient and thus, to calculate the
spacing in linear measuring units (micrometers, millimeters or meters).
