There is a certain advantage of easier measurementin exposure starting time comparing with rolling shutter.Shutter mode comparison 3Global reset(rolling shutter＋global reset)1st line: exposureTrigger input2nd line: exposureData reading各ラインごとに露光開始タイミングが異なる。3rd line: exposure・・・・・Last line: exposureExposure time length is different in each line・・・Output image1 2 3 ・・・・123・・・・・・・・Resetting andstarting exposurein all the lines atthe same timeStarting time of exposure is same in each line. However, exposuretime length are longer in lower line. Hence distortion andluminance difference in image is caused under constant light.Aptina_5MAs no difference in exposure starting time in lines like rollingshutter, exposure starting time can be measured easily asglobal shutter.However, as exposure ending time is different in each line,image of moving subject under constant light is distortive dueto luminance difference.2015/12/25
