=====Rolling shutter=====

The rolling shutter sensor is implemented as shown in the figure below.。The exposure starts from the first line and the second line is exposed only after one line cycle.And so on, after N-1 rows the Nth row is exposed.It takes one cycle time to read out a row of data after the first row is exposed.After the first line is completely read out, the second line just starts to be read out. In this order, the whole image is completely read out. The rolling shutter sensors are less technically difficult than global exposure sensors, cheaper, and have greater resolution, making them a good choice for some static or slow object photography.

===== Global shutter =====

The global shutter sensor implementation is shown in the figure below. All rows of the sensor start exposure at the same time and end exposure at the same time. At the end of the exposure, the sensor transfers all electrons from the sensing area to the storage area and then reads out the pixel data row by row.The advantage of such exposure is that the image will not be shifted and skewed when shooting moving objects.
