Problems solved by technology

[0004] However, the methods in the prior art can only achieve relatively accurate stroboscopic detection in some specific scenes. In the face of some complex scenes, especially in scenes such as weak flickering of the light source, shaking of the picture, or occurrence of striped motion textures, the prior art The method is prone to false detection or missed detection, which will lead to the elimination or suppression of stroboscopic at the wrong moment, which will also have a great impact on the imaging quality

Abstract

The invention discloses a stroboscopic detection and elimination method, a stroboscopic detection and elimination device, a camera and a storage medium, which are used for accurately and reliably detecting a stroboscopic phenomenon. The method comprises the following steps: acquiring a preview image; performing binarization processing according to the difference image of the two adjacent frames of preview images to obtain a binarized image; calculating an integral projection of the binarized image; judging whether the binary image accords with stroboscopic stripe features or not according to the integral projection to obtain a feature judgment result; and determining whether the image is in a stroboscopic state or not according to the feature judgment result.

Description

technical field [0001] The present application relates to the field of image processing, and in particular, to a stroboscopic detection and elimination method, device, camera and storage medium. Background technique [0002] Strobe, also known as power frequency flicker and power-line flicker, is a common physical phenomenon when shooting and video recording in an AC light source environment. When stroboscopic occurs, alternating light and dark and moving stripes will appear in the image screen, which will seriously affect the image quality and bring about a bad user experience. [0003] In order to eliminate or suppress stroboscopic, it is necessary to carry out accurate and reliable detection of stroboscopic phenomenon first. In the prior art, it is usually determined by calculating the difference vector whether there is stroboscopic phenomenon in the current image frame; [0004] However, the method in the prior art can only achieve relatively accurate stroboscopic dete...
