Abstract: A monitoring device includes an image capturing module, a photosensitive element, a first processing module and a second processing module. The photosensitive element obtains a lighting parameter of a monitored environment. The first processing module is electrically connected to the photosensitive element, stores the lighting parameter, and continuously updates the lighting parameter. The second processing module is electrically connected to the image capturing module and the first processing module, and the second processing module has a sleep mode. The second processing module includes an exposure function control unit. When the second processing module is awakened and converted to a recording mode, the exposure function control unit receives the updated lighting parameter from the first processing module and calculates an exposure parameter according to the lighting parameter to control the image capturing module.
