Embodiment Construction

[0025] The present invention proposes a method for lens imaging compensation, the core of which is to irradiate a white viewing area with parallel light. In practical applications, the white viewing area can be a piece of white paper; the image information of the white viewing area is collected through lens imaging; Then, carry out data analysis on the image information to obtain the compensation gain value of the gray value of each point in the image; finally, in the lens imaging process, the gray value of each point in the obtained image is compensated by the compensation gain value After that, reimage and output the image.

[0026] The concrete process of the present invention is as figure 1 Shown:

[0027] Step 11, irradiate a piece of white paper with parallel light; generate a set of image information through lens imaging;

[0028] Step 12, extracting the gray value of the three components of red R, green G, and blue B from the image information to obtain three sets of...

Abstract

A imaging compensation method of lens includes using parallel light to shine white view finding region to obtain image information of said region, analyzing said image information for obtaining compensation gain value of grey value at each point on image, carrying out compensation gain treatment in imaging course of lens according to obtained compensation gain value of grey value at each point on image then carrying out imaging and outputting image.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for lens imaging compensation in image processing. Background technique [0002] When an ordinary optical lens is used for imaging, due to the influence of the lens and optical characteristics, the edge of the image will generally be darker than the center, and even serious color distortion will appear. In order to obtain a high-quality image, it is necessary to correct the image. [0003] The current existing correction method is generally to multiply a gain in the darker area, but there are many problems in this method, such as: how to choose the gain, how to avoid more serious color distortion when the gain is too large, and Whether the calibration is accurate and so on. Contents of the invention [0004] In view of the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide a method for lens imaging compensa...
