Description
Master clock: Camera works with external clock generator. Used for
synchronizing several camera systems. For timing information, see section
2.9 Timing.
External synchronization: Camera is externally triggered and delivers image
data in response to a trigger signal. For timing information, see section 2.9
Timing.
Constant frame rate: Ensures constant frame rate (data quantity) so that the
camera delivers only a limited number of images/second (at constant
exposure time). You can set the number of images/second. For timing
information, see section 2.9 Timing.
Skimming: Increases small signal gain at the sensor level and increases
camera sensitivity. See section 1.7 Gain Response for details.
Turns image upside down. See section 1.11 Flip Image Mode for details.
Camera delivers 8 bit data (Gray levels 0...255).
Linear-Feedback-Shift-Register: Generates a pseudo-random image so errors
can be identified in the complete image processing system. See Appendix D
