Problems solved by technology

In portrait photos, the photo screen is often grayed out and the layers are not clear, so that the subject is not prominent and the whole picture looks flat. However, the current image processing software mainly adds dark tones to the four corners of the image. In order to achieve the effect of vignetting, to show the mysterious atmosphere and the feeling of a special environment, but this adjustment will often make the adjusted visual sense darker, thus affecting the appreciation of the image

Embodiment Construction

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] Such as figure 1 Shown, a kind of method of the present invention adds vignetting effect for image, it comprises the following steps:

[0040] 10. Preset the mask image, the periphery of the mask image is white, the center is black, and the center to the periphery is gradually transitioned from black to white, such as figure 2 shown;

[0041] 20. Load the image to be processed and the preset mask image;

[0042] 30. Scale the preset mask image to make it consistent with the size of the image to be processed;

[0043] 40. Adjust the pixels of...

Abstract

The invention discloses a method for adding a vignette effect into an image, and the method is characterized in that a mask image is preset and has a white periphery and a black center, the region from the center to the periphery is gradually transited from black to white, the preset mask image is zoomed to coincide with the to-be-processed image in size, the pixel point of the to-be-processed image is adjusted according to the mask image to gain the resulting image, and the periphery of the image is dimmed and the center of the image is brightened such that the adjusted vignette has the better effect, the more natural tone transition and the better appreciation value and the selection regions aren't defined, thus the method can be quickly operated.

Description

technical field [0001] The invention relates to an image processing technology, in particular to a method for adding a vignetting effect to an image. Background technique [0002] The term vignetting belongs to the term of photography. Facing a scene with uniform brightness, the four corners of the picture appear to be darkened, which is called "lost light", commonly known as "vignetting". In portrait photos, the photo screen is often grayed out and the layers are not clear, so that the subject is not prominent and the whole picture looks flat. However, the current image processing software mainly adds dark tones to the four corners of the image. In order to achieve the effect of vignetting, to show the mysterious atmosphere and the feeling of a special environment, but this adjustment will often make the adjusted visual sense darker, thus affecting the appreciation of the image. Contents of the invention [0003] To solve the above problems, the present invention provide...
