Figure 7-1: (Color Only) Bayer pattern for a color camera with ReverseX and ReverseY set to false.
The Bayer phase of the color camera with deactivated functions is defined in Figure 7-1. Pixel(0;0) is the first
pixel from the camera (left-top pixel in image), the corresponding Bayer phase is GBRG. If the
ReverseX
and
ReverseY
functions are activated, the Bayer phase changes (
PixelFormat
) according to the table below.

No test pattern is shown.
AdimecTestPattern
Specific Adimec test pattern with grey bars, color bars (only active in a
color camera) and contour lines, see Figure 7-2.
UniformVideoLevel
Uniform test pattern to verify corrections. The video level can be set with
the TestImageVideoLevel feature.
DiagonalPattern
The diagonal test pattern is defined by
V
x,y
= (x + y) modulo 2
N
where N
represents the bit depth and V
x,y
the digital pixel value at pixel (x,y). See
Figure 7-3 for the resulting pattern.
DiagonalPatternRunning
(ISSUE 2 ONLY)
This running test pattern is different from the diagonal test pattern by the
addition of the frame counter in the defining formula:
V
x,y
= (x + y + frame
counter) modulo 2
N
.
See Figure 7-3 for the resulting pattern.
The camera can generate test patterns in the mode the camera is currently working. The camera will continue to
work in the selected mode, but instead of the usual image an artificial image is displayed.
NOTE:
The test patterns are amplified with the set gain.
NOTE:
The test image is resized when a different width and/or height is set.
