Abstract

An image scanning method includes pre-scanning a first document to generate a first original image according to the first document; adjusting parameter settings of the first original image to generate and store a plurality of pre-view images corresponding to different sets of parameters; pre-scanning a second document to generate a second original image according to the second document; and scanning the second document to generate a plurality of scanning images according to the different sets of parameters of the pre-view images. The parameter settings of the first original image include brightness, shadow, and contrast settings.

Claims

pre-scanning a first document to generate a first original image according to the first document;

adjusting parameter settings of the first original image to generate and store a plurality of pre-view images corresponding to different sets of parameters;

pre-scanning a second document to generate a second original image according to the second document; and

scanning the second document to generate a plurality of scanning images with the different sets of parameters of the pre-view images.

2. The method according to claim 1, wherein the parameter settings of the first original image include brightness, shadow, and contrast settings.

3. The method according to claim 2, wherein the first original image, the pre-view images, and the second original image are displayed by a display interface.
