TERMINOLOGY
Defective pixels
– these are pixels whose sensitivity deviates due to fluctuations in the CMOS
manufacturing process and materials.
Fast trigger mode
– a camera exposes a frame and then exposes the next frame while reading
out the previous frame. In this way, the camera overlaps the exposure and readout times. Fast
trigger mode requires a predictable and stable trigger period. The
TriggerOverlap
setting is On.
Free-running mode
– a camera runs without synchronization to an external trigger pulse
(untriggered mode).
Hot pixels
– these are pixels that in normal camera operation behave as normal pixels (sensitivity
equal to one of the adjacent pixels). But during long exposures or at elevated temperatures, the
pixel becomes far brighter than the average of the pixels surrounding it. In some cases, the pixel
becomes so bright that it saturates.
Standard trigger mode
– a camera waits for a trigger pulse, then exposes using an internal
exposure timer and reads out a frame and waits for next trigger pulse. The exposure and readout
do not overlap. The
TriggerOverlap
setting is Off.
Trigger mode
– a camera waits for a trigger pulse to start the image capture, synchronizing it to
either an internal or external event.
