Problems solved by technology

This is not only inefficient, but also because the color adjustment is only performed inside the selection area, it is easy to cause the transition of the selection area boundary to be uneven, produce a staircase effect, or change the original image characteristics

Embodiment Construction

[0040] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0041] figure 1 The structure of the system for adjusting the local color of an image in this embodiment is shown. Such as figure 1 As shown, the system includes an acquisition device 11 , a calculation device 12 connected to the acquisition device 11 , an adjustment device 13 connected to the calculation device 12 , and a storage device 14 connected to the adjustment device 13 . Wherein, the acquiring device 11 includes an extracting unit 111 and a setting unit 112 .

[0042] The acquiring device 11 is used for acquiring the color to be adjusted and the range of influence of the color adjustment. The color to be adjusted and the range of influence of the color adjustment can be extracted from the image by the extraction unit 111 , or the value of each space of the color to be adjusted and the range of influence of the color adjustment can be ...

Abstract

The invention relates to a method and system for adjusting local color of an image and belongs to the technical field of image processing. The method comprises the following steps: firstly, obtaining a to-be-adjusted color and an influence scope of color adjustment; calculating a diversity factor between a pixel point color of the color in the influence scope and the to-be-adjusted color; and calculating the adjustable amplitude of the pixel point color in the influence scope according to the influence scope and the diversity factor, and adjusting the local color of the image in the scope of the adjustable amplitude. According to the method provided by the invention, the to-be-adjusted color and the scope can be appointed by a user; the adjustable color is random, so that the user more clearly knows the adjusted color; and the adjusting scope can be set, so that the adjustment is more accurate.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a method and system for adjusting local color of an image. Background technique [0002] In image processing, it is often necessary to adjust the color of a part of an image. Currently, adjusting the color of a local area of ​​an image is mainly based on the base color. [0003] At present, in order to adjust a certain color without changing the similar color, the retouching personnel must manually select the color area to be adjusted in the image and then adjust it. This old practice is inefficient and can easily cause image matte problems. [0004] Moreover, there are only 9 colors in the existing color adjustment method, and each color represents a large range of color spaces that overlap with each other, and the range of color spaces is not clear. This results in the following drawbacks: [0005] Adjustment blindness. For example: to adjust red, the ...
