Abstract

The invention discloses an image scanning device and a control method thereof. The image scanning device comprises a receiving member, a light source, a lens, a first converter and a controller, wherein the bearing member is used for receiving paper bills; the incidence side of the lens and the receiving member are correspondingly arranged, and the lens is used for receiving reflected light or transmission light of the paper bills under the irradiation of the light source and receiving emitted light of the light source; the first converter is arranged on the emergent side of the lens and is used for converting light signals from the lens into electric signals; and the controller is connected with the light source and the first converter, and is used for controlling light emitting time of the light source, acquiring electric signals during the light emitting process of the light source, and acquiring electric signals again after a preset time when the light source stop emitting light. With the adoption of the image scanning device and the control method thereof, the problem of low paper bill scanning precision in the prior art is solved, and the effect of increasing paper bill identification accuracy is achieved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image scanning device and a control method thereof. Background technique [0002] In recent years, automatic equipment for processing banknotes and bills or various securities such as banknote counting machines, banknote detectors, and automatic deposit and withdrawal machines has become popular. False scanning device for authentication. [0003] These scanning devices identify the authenticity of paper bills by detecting reflected or transmitted images. For example, there is a way to detect authenticity by scanning secondary light excited by ultraviolet light sources, infrared light sources, etc. The so-called secondary light refers to fluorescence, phosphorescence, infrared light, etc. that are generated when the ink and paper are excited by the irradiated light. [0004] However, there are various anti-counterfeiting technologies for paper bills in various countri...
