5.11 Defective Pixels Correction
The sensor may present defective pixels. Hot pixels have a higher value than the average of
their neighbor pixels. A correction can be applied by replacing these defective pixels by the aver-
age value of their neighbors. The threshold which determines if a pixel is defective can be
programmed. This threshold is defined in LSB value above the average value of the neighbor
pixels.
See register Defective Pixel Control @ 2C4H, Internal Register Mapping on page 16.
See register Hot Pixel Detection Threshold @ 2C0H, Internal Register Mapping on page 16.
5.12 LED Indicator
The green LED on the rear panel gives information on the internal state of the camera. On
power up, after internal configuration, the LED flashes on and has the following behavior
(decreasing priority order):
• Internal hardware error or configuration error: fast blinking
• Waiting for external trigger (triggered and ITC modes): slow blinking
• All other situation: continuous
