IMAGE AND DATA FORMATTING
NOTE:
the offset is defined at the camera output on a 12 bit scale. That means that if the camera is
switched to another output resolutions than 12 bit the actual offset seen on the output will be different.
Assuming the camera is running at a gain value equal to y and a black level equal to x:
Offset on Camera Output with an output resolution of 10 bit = x.y/4
Offset on Camera Output with an output resolution of 8 bit = x.y/16
See par 8.6 for information about output resolution and the the OR command.
For color cameras, the blacklevel command is not available. Use the offset command instead to alter
the output offset.
Defect pixels
8.12
Introduction
8.12.1.
The OPAL series camera do have a feature to correct for defect pixels real time.
This is done by interpolating the adjacent pixels according to the method illustrated in figures 8.6 and
8.7.
Defect pixel correction method on monochrome cameras.
Figure 8.6:
Defect pixel correction method on color cameras.
Figure 8.7:
Up to 3 adjacent pixels can be corrected by the above method. More than 3 adjacent defect pixels can
be user programmed, but may not result in a reliable correction.
Adimec does not release cameras with more than 3 adjacent defect pixels upon delivery.
Defect Pixel information
8.12.2.
At manufacturing, a table is generated for each individual camera in order to correct for defect pixels.
This table is stored in non volatile memory and can be read back from the camera. The number of
defect pixels and the locations of each defect pixel can be obtained.
Command syntax: DP?n
