The exposure and the readout method of the CMOS image sensor is rolling shutter.
In the rolling shutter, the exposure and readout are done line by line. Therefore, the exposure
timing is different on one screen. (Figure 9-2)
But even if the object moves during the exposure, the affect of rolling shutter is very small.
