Flash pulse-on interval in dark scene
A graphic from patent 8,150,255 shows an example timing of an ERS exposure for which the flash pulse-on interval is longer than the overlap interval but shorter than then image-framing period when a dark scene is being indicated.
"When the scene is indicated to be dark," according to the patent, "the integration time is lengthened and the flash pulse-on interval is set to be shorter than the complete exposure interval, but longer than the row overlap time interval."
