Abstract

The embodiment of the invention provides a pupil bright spot elimination method, which is applied to the technical field of image processing. The method comprises the steps of obtaining a target image, wherein the target image comprises a pupil area with pupil bright spots; for each partition of the pupil region in the target image, correcting the pixel value of the pixel point in the partition into the pixel value mapped by the partition by using a pre-trained target mapping relationship between the partition of the pupil region and the pixel value, wherein the pixel value mapped by each subarea is the pixel value of the pixel point of the subarea after the bright spot is eliminated. Through the scheme, pupil bright spots in the image can be eliminated, and the imaging effect of the image is improved.

Description

technical field

[0001] The invention relates to the technical field of image processing, in particular to a pupil bright spot elimination method. Background technique

[0002] With the development of technology, imaging technology is more and more widely used in all walks of life, such as taking pictures through mobile phones and video monitoring through cameras.

[0003] Generally speaking, in the case of good lighting conditions (sufficient light source), the imaging quality of the image generated by the imaging device is better, but in the case of poor lighting conditions (such as night), the image generated by the imaging device tends to Contains more noise and poor image quality. In order to improve the imaging quality of images under poor lighting conditions, a special light-splitting structure and dual-light fusion technology can be used to make the generated image integrate the color information of visible light images and the signal-to-noise ratio advantages of inf...
