An electronic display device includes a storage device for storing an image file, a display screen for showing the image file, a positive evaluation button, and a statistical program. The electronic display device is in communication with a social website. When the positive evaluation button is pressed down, a positive evaluation signal is generated. The statistical program has a preset evaluation threshold value. The statistical program generates an evaluation value according to the positive evaluation signal. If the evaluation value is greater than or equal to the evaluation threshold value, the image file is transmitted to the social website.

An image pickup system includes a display screen, an image pickup device and a positioning program. The image pickup device is used for shooting a document. The display screen is used for showing a positioning mark. When the document is moved and a pre-shot document image is aligned with the positioning mark, the image pickup device is activated by the positioning program to shoot the document, thereby obtaining a document image.

Image pickup system

Verification of areas within an image corresponding to banknotes includes dividing the image into a plurality of image sections; generating a banknote boundary map having border sections corresponding to a boundary of monetary banknotes within the image; generating a texture decision map having texture sections within a valid range according to a valid monetary banknote; determining a number of objects in the texture decision map by removing texture sections in the texture decision map that correspond to the border sections in the banknote boundary map; calculating a texture property value for each object; calculating a shape property value for each object; and further removing texture sections from the texture decision map corresponding to objects that do not have the texture property value within a first predetermined range and the shape property value within a second predetermined range.

Verification method for determining areas within an image corresponding to monetary banknotes

A method for adjusting an image signal by a processor includes providing a first low pass filter and a second low pass filter, generating an energy ratio of a band-pass image signal and the image signal according to the standard deviation of a first low pass signal of the first low pass filter and a second low pass signal of the second low pass filter, providing an image adjustment parameter and generating a weighting coefficient of the image signal according to the energy ratio and the image adjustment parameter, generating a third low pass filter according to the weighting coefficient of the image signal, the image adjustment parameter, the first low pass signal of the first low pass filter and the second low pass signal of the second low pass filter, and adjusting the image signal according to the image signal and the third low pass filter.
