Abstract

The invention relates to a histogram debugging method of a colored image and a debugging system thereof. According to the method, subarea nodes and subarea thresholds of a histogram of a colored image are arranged; according to an obtained node group with the thresholds, weighted translation calculation is carried out on each gray scale to obtain offset gray scales; and then each the gray scale of the colored image is replaced into each the offset gray scale. In addition, the system comprises a subarea node module, a subarea threshold module, a histogram subarea module, a threshold setting module, a gray scale transformation module and an image correction module. According to the invention, the following advantages are provided: novel functions, simple realization, low cost, and obvious debugging effect and the like. Moreover, according to the invention, a histogram is utilized to realize debugging on RGB image gray scale by a user. Therefore, a limitation on a gray scale debugging function of preset software can be broken through and furthermore, the user can set a random interval of a histogram of an image and a random threshold in the interval according to own needs of the user, thereby embodying strong interactivity, flexibility and generality. Therefore, the invention has a wide application prospect.

Description

technical field

[0001] The invention relates to a color image debugging method and system, in particular to a color image histogram debugging method and a debugging system thereof, belonging to the technical field of digital image processing. technical background

[0002] Due to the influence of various factors such as shooting light and shooting environment, many current color images often have various uneven brightness distributions. For the viewer of the picture, the uneven light and dark image is not only difficult to read, but also difficult to give a true description of the object being photographed. Especially in the application field of judging by reading images, it is easy for observers to make wrong judgments and cause unnecessary losses. Therefore, it is necessary to adjust the grayscale of the color image to balance the grayscale of the color image and further improve the quality of the color image.

[0003] At present, some image processing software can realiz...
