Internal Image Test Patterns
The Genie camera includes a built in test pattern generator that can be used to confirm camera Ethernet connections
or driver installations, without the need for a camera lens or proper lighting. The pattern generator inserts video just
after the sensor A/D converter, therefore Genie processing such as the LUT act on the generator images or on sensor
images.
CamExpert is used to easily enable and select the Genie test patterns. As shown in the following figure, select the
Sensor tab, then select one of the four patterns from the drop menu. Select live grab to see the pattern output.
Genie Test Pattern Selection – on Sensor Tab
The Genie test patterns are:
• Horizontal ramp: successive pixel's gray level is incremented by 1 to maximum pixel value then repeated until
the end of line. The gray level is reset to 0 on the following line.
• Vertical ramp: similar to the horizontal ramp, successive lines are incremented by 1 gray level then repeated
for the full frame.
• Moving diagonal ramp: combination of the 2 previous schemes, but first pixel in image is incremented by 1
between successive frames. This is a good pattern to indicate motion when doing a continuous grab.
• Purity: a purity pattern where all pixels have the same value. The gray value is incremented by one on
successive frames to maximum then repeated. This also provides motion for live grabs.
