Image-processing method and apparatus

Abstract

The invention discloses an image processing method which comprises the following steps: the statistics of the numbers of pixels which are respectively corresponding to green (G) and blue (B) component values in all the pixel points of an original image within a preset value interval is carried out; an original image is copied to obtain a temporary image, the numbers of the pixels which are respectively corresponding to G and B component values are compared, if G is more than or equal to B, red (R) component values in each pixel point of the temporary image are all replaced by the G component values on the pixel point; otherwise, the R component values in each pixel point of the temporary image are all replaced by B component values on the pixel point; the temporary image after being treated is overlapped onto the original image according to the brightness mode, and the needed image is finally obtained. The invention simultaneously discloses an image processing device. Through the application of the method and the device of the invention, the red overflow phenomenon in the image can be conveniently and effectively repaired.

Description

Technical field [0001] The present invention relates to image processing technology, in particular to an image processing method and device capable of effectively repairing red overflow. Background technique [0002] With the increasing popularity of digital cameras, users have put forward higher requirements for the effects of digital photos taken. However, because digital photosensitive materials have very poor resolution of red, red objects are often photographed lacking a sense of layering, and a red mass appears, that is, red overflow. For example, when photographing safflower with a digital camera, it is difficult to clearly distinguish the gradation of the petals. [0003] To solve this problem, users usually need to use some software to perform post-processing on the digital photos taken. However, this processing is usually achieved by adjusting a series of complex parameters. In fact, in order to correct the photos, You can only manually adjust the level, brightness or c...

AI Technical Summary

Problems solved by technology

However, due to the poor resolution of digital photosensitive materials for red, often the red objects captured lack a sense of layering, appearing in a red mass, that is, the phenomenon of red overflow

For example, when photographing safflower with a digital camera, it is difficult to clearly distinguish the layers of petals in the photographed safflower

[0003] In order to solve this problem, users usually need to use some software to post-process the captured digital photos. However, this processing is usually achieved by adjusting a series of complex parameters. In fact, in order to correct photos, users need to You can only manually adjust the level, brightness or contrast of the photo by yourself, which is not only inconvenient to implement, but also difficult to achieve the desired effect
