Embodiment Construction

[0020] In order to make the purpose, technical solution and advantages of the present application clearer, the present application 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 application, and are not intended to limit the present application.

[0021] It can be understood that the terms "first", "second" and the like used in this application may be used to describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, a first image could be termed a second image, and, similarly, a first camera could be termed a second camera, without departing from the scope of the present application. Both the first image and the second image are images, but they are not the same image. Both the first camera and the se...

Abstract

The invention relates to an image generation method and device, an electronic device and a computer readable storage medium. The method comprises the steps of obtaining a first image collected by a first camera; when it is detected that the first image contains the moving object, detecting the ambiguity of the first image; when the ambiguity of the first image is smaller than a preset ambiguity, obtaining a first exposure parameter corresponding to each frame of the first image in the first image sequence, and recording the first image in the first image sequence; determining at least two second exposure parameters of the second camera according to the first exposure parameter corresponding to each frame of the first image; and controlling the second camera to acquire a second image with at least two second exposure parameters so as to generate a high-dynamic-range image. By the adoption of the method, the ghosting phenomenon can be reduced, and then the quality of the high-dynamic-range image is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an image generation method and device, electronic equipment, and a computer-readable storage medium. Background technique [0002] HDR images (High-Dynamic Range, high dynamic range) can provide more dynamic range and image details than ordinary images. The traditional HDR image synthesis method is to collect multiple images according to multiple preset exposure parameters, and synthesize an HDR image based on the multiple images. However, if there are moving objects in the scene, ghosting is likely to occur during HDR composition. Contents of the invention [0003] Embodiments of the present application provide an image generation method and device, electronic equipment, and a computer-readable storage medium, which can reduce ghosting and further improve the quality of high dynamic range images. [0004] An image generation method, comprising: acquiri...
