Abstract

The embodiment of the invention discloses an image processing method and device, a storage medium and electronic equipment, and the method comprises the steps: obtaining a latest frame of image in an image frame sequence outputted by a camera, and taking the latest frame of image as a current frame of image; calculating a first initial correction parameter table of the current frame image according to a shadow correction algorithm; processing the first initial correction parameter table to obtain a first target correction parameter table; and performing correction processing on the current frame image according to the first target correction parameter table. On the basis, the first initial correction parameter table is processed to improve the accuracy of the correction parameters, and the processed first target correction parameter table is used for correcting the current frame image, so that the accuracy of image lens shadow correction is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an image processing method, device, storage medium and electronic equipment. Background technique [0002] Lens shading is the uneven brightness and color of an image due to the optical characteristics of a lens. Lens shading is divided into luma shading and color shading. Among them, the brightness shadow is due to the optical characteristics of the lens, the light intensity received by the edge area of ​​the image area of ​​the camera sensor is smaller than that of the center, resulting in inconsistent brightness between the center and the four corners. In addition, due to the different wavelengths of various colors, the refraction angle of the lens is also different, so color shadows will appear. The correction accuracy of the shading correction algorithm in the related art is low. Contents of the invention [0003] Embodiments of the present applic...
