- Rolling_shutter abstract "Rolling shutter is a method of image acquisition in which a picture or each frame of a video is recorded not from a snapshot of a single point in time, but rather by scanning across the frame either vertically or horizontally. In other words, not all parts of the image are recorded at exactly the same time, even though the whole frame is displayed at the same time during playback. This produces predictable distortions of fast-moving objects or when the sensor captures rapid flashes of light. This is in contrast with global shutter in which the entire frame is exposed for the same time window. This is equivalent to the focal plane shutter in film cameras where curtains go across the film with an opening between them, adjusting exposure by adjusting the width of the slit. (The focal plane is where the image is captured, and the focal plane shutter is very near it, between the image capturing plane and the lens.)Electronic flashes with a single short exposure can only illuminate the image area if the slit is the width (or height, for vertical shutters) of the entire area. That is why use of electronic flash is often limited to 1/60 second though a camera may support 1/4000 second exposure time with continuous light like daylight.This method is implemented by rolling (moving) the shutter across the exposable image area instead of exposing the image area all at the same time. The shutter could be either mechanical or electronic. The advantage of this method is that the image sensor can continue to gather photons during the acquisition process, thus increasing sensitivity. It is found on many analogue photo cameras - practically all SLRs use a rolling shutter at higher shutter speeds -- as well as digital still and video cameras using CMOS sensors. The effect is most noticeable when imaging extreme conditions of motion or the fast flashing of light. While some CMOS sensors use a global shutter, the majority found in the consumer market utilize a rolling shutter.CCDs (charge-coupled devices) are alternatives to CMOS sensors. CCDs utilize what is referred to as global shutters, which take a snapshot representing a single point of time and therefore do not suffer from these motion artifacts.".
