Document scanning image correction method and device, storage medium and electronic equipment

Abstract

The embodiment of the invention provides a document scanning image correction method and device, a storage medium and electronic equipment. In the technical scheme, a document scanning image is obtained, the document scanning image comprises multiple page scanning images, brightness detection is carried out on each page scanning image to obtain brightness values of multiple pixel units in each page scanning image, and the brightness values of multiple pixel units in each page scanning image are compared with the brightness values of multiple pixel units. And the brightness values of the pixelunits of which the brightness values are lower than a preset brightness value are corrected to a preset brightness mean value, generating corrected page scanning images from the corrected pixel unitsand the remaining pixel units, splicing the plurality of corrected page scanning images to generate corrected document scanning images, and outputting the corrected document scanning images. The problem of poor scanning result caused by uneven brightness of the document scanning image is avoided, so that the scanning quality of the document scanning image is improved, and the scanning efficiency of the document scanning image is improved.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a correction method, device, storage medium and electronic equipment of a document scanned image. Background technique [0002] Current document processing equipment has become an indispensable equipment in offices or personal homes. Common document processing equipment includes automatic document feeder scanners, multifunctional office machines or copiers. As far as the scanner is concerned, the user needs to place documents in the paper tray of the scanner, and the scanner will feed the documents sequentially, and generate scanned images of the documents after reading the documents. And when there are "wrinkles" in the pages in the document, or the document is not placed correctly, or the lamp tube of the scanner is tilted, it is easy to cause the generated document scanned image to appear skewed. [0003] In the prior art, when there are "wrinkles" in the...

Problems solved by technology

[0004] In order to solve the above-mentioned situation in the prior art that there are pages with "wrinkles" in the document, it is usually necessary to manually find the pages with "wrinkles" from the document, remove the "wrinkles" from the page, and then re- The page is scanned, so it is easy to cause the problem of low document scanning efficiency. The present application provides a method, device, storage medium and electronic equipment for correcting scanned document images
