Abstract
A license plate capturing device includes an image capturing unit, a plurality of infrared light emitting units, a driving circuit and a control circuit. The plurality of infrared light emitting units is located around the image capturing unit. Each of the infrared light emitting units emits invisible light having a predetermined wavelength that has an absorption band of a target. The driving circuit is coupled to the infrared light emitting units. The control circuit is coupled to the driving circuit and the image capturing unit, and controls the driving circuit to execute one of a normal driving mode and a continuous driving mode. In the continuous driving mode, the driving circuit continuously provides a driving current to the infrared light emitting units for a continuous period of time so as to remove a target covering the license plate capturing device.
