TRIGGER READY OUTPUT

The trigger ready output is useful to make the frame intervals as short as possible in External

trigger mode. For example, when the camera is working in Edge trigger mode, the next frame

can start after the previous frame exposure and sensor readout are done. Thus, the camera

cannot accept a trigger for the next frame during the exposure and readout period. To reduce

useless time to be as short as possible, it is necessary to know the period when the camera can

accept a trigger for the next frame. The trigger ready output shows the trigger ready period when

the camera can accept an external trigger in External trigger mode.

9-9

The camera features an on-chip gain control capability that can multiply the analog signal in CMOS

sensor prior to converting it into a digital signal. The setting range for analog gain is 0 dB to 24 dB

and the minimum setting step is 0.1 dB.

9-10

There is a chance that the data from variant pixels caused by illumination and optics cannot be

negligible in the imaging with camera. The camera has the variant pixel correction feature for a

further image quality improvement. The correction can be effective in real-time without scarifying

the readout speed at all.
