• If the values for both features are reversed, so that
ContrastAutoIntensityMax
is set to a value lower than the value of
ContrastAutoIntensityMin
, than the affected area of the image turns into

Frame memory
Goldeye cameras capture and transmit each image in consecutive steps. The image
is taken, read out from the sensor, digitized, and transmitted to the host computer
over the connection used, either Camera Link or Gigabit Ethernet.
For buffering the frames before transmission, a certain amount of RAM is available.
The number of frames in the frame memory depends on the defined ROI and the
pixel format.
Table 140 shows the memory size and the number of frames
(StreamHoldCapacity) that can be stored by each model.
