Abstract: A shooting device including a camera lens and a controller is provided. The camera lens is configured to shoot a picture. The controller, electronically coupled to the camera lens, divides the picture into a plurality of initial blocks each corresponding to an initial brightness value, selects at least one selection block from the initial blocks, and calculates an average brightness value according to the initial brightness value corresponding to the at least one selection block.

Abstract: A short pulse generating circuit including a pulse generating circuit, an actuation control circuit and a delay control circuit is provided. The pulse generating circuit is electrically coupled to a switch, which is coupled to a power. When the power is turned on, the power causes the pulse generating circuit to generate a long pulse. The actuation control circuit is electrically coupled to the power and the pulse generating circuit. When the power is turned on, the actuation control circuit controls a voltage level of each output of the pulse generating circuit to a fixed value. The delay control circuit is electrically coupled to the pulse generating circuit. When the switch is turned on, the power controls the delay control circuit to change the voltage level of each output of the pulse generating circuit to generate a short pulse output.
