14. 000 camera has an electronic rolling shutter a snapshot of a moving object can give a slanted image This effect is caused by the time difference of each line that is exposed to light To overcome this the flash mode can be useful In normal operation the electronic shutter is opened at the same speed as pixel readout the opening shutter rolling over the sensor like a curtain When the camera is set to flash mode the shutter is opened very quickly approx 30 ms for a full frame and stays open during the programmed integration time During this period an optional flash ready signal can be set on the trigger output This signal can be used to trigger an external flash unit After the integration time the imager is readout at normal speed Please note that during the readout period the image sensor is still sensitive to light causing the last line to be exposed to light longer than the previous lines With constant lighting this would create an image with a gradient from darker first line to lighter last line The flash mode is therefor best used in dark or low light conditions Alternatively the user can compensate for this effect in software Shutter opening E Integration time Readout time 1 1 1 1 1 Trigger Readout and closing of shutter Imager lines Time 1 Flash ready Trigger Output Actual exposure time of first line Actual exposure time of last line
