5.13 Shutter or Shutter Limit
When the shutter released button is pressed, the shutter curtain will be opened, and the CMOS
sensor which is behind the shutter curtain will receive the light. The light will penetrate by the IRIS
of the camera. When the shutter is open, the light will irradiate on the CMOS sensor. After that,
the shutter curtain will go back to its original place to cover the CMOS sensor and the light will be
stopped by the shutter curtain. This is the process for taking a picture. The time length that the
CMOS sensor is irradiated by the light is called “Exposure Time”. If the time length is 1 second, it
means that the exposure time is 1 second. Different shutter speed can achieve different function
and performance. Generally speaking, “high shutter speed” can freeze each moment. However,
the slow shutter speed can record the scenario such as the cars are flowing on the road.

Note: It is recommended to set the shutter speed to be two times of the frame rate. For example,
if the frame rate is set as 25p, the shutter speed must be set at 1/50. If the frame rate is 29.97p,
the shutter speed must be set at 1/60.
