Embodiment Construction

[0039] 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.

[0040] 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 camera could be termed a second camera, and, similarly, a second camera could be termed a first camera, without departing from the scope of the present application. Both the first camera and the second camera are cameras, but they are not the same camera.

Abstract

The invention relates to an image acquisition method and device, electronic equipment and a computer readable storage medium. The method comprises the following steps of: acquiring at least two framesof corresponding first images by using at least two different first exposure parameters through the first camera; performing content analysis on each frame of first image; and determining at least two second exposure parameters according to the content analysis result and the at least two different first exposure parameters, carrying out image acquisition through a second camera according to theat least two second exposure parameters to obtain at least two corresponding frames of second images, and carrying out fusion processing on the at least two frames of second images to obtain a targetimage. Due to the fact that the exposure parameters of the images used for fusion can be obtained through analysis according to the multiple frames of images collected by the first camera, the secondcamera collects the images according to the exposure parameters and then carries out fusion, and the quality of the collected images can be improved.

Description

technical field [0001] The present application relates to the field of image technology, and in particular to an image acquisition method, device, electronic equipment and computer-readable storage medium. Background technique [0002] Since the brightness range that the human eye can see is much larger than the brightness range provided by the display screen and the camera, there is a big difference between the brightness of the object observed by the human eye and the brightness of the image captured by the camera. Currently, during the image acquisition process, the camera can acquire multiple images with multiple preset exposure parameters, so as to synthesize an HDR (High-Dynamic Range, high dynamic range) image based on the multiple images. However, the synthesized HDR images in traditional methods suffer from low quality. Contents of the invention [0003] Embodiments of the present application provide an image acquisition method, device, electronic device, and com...
