Embodiment Construction

[0049] The following exemplarily introduces related content that may be involved in the embodiment of the present application.

[0050] In the description of the present application, unless otherwise specified, " / " means "or", for example, A / B may mean A or B. The "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B, which can mean: A exists alone, A and B exist at the same time, and B exists alone These three situations. In addition, "at least one" means one or more, and "plurality" means two or more. Words such as "first" and "second" do not limit the number and order of execution, and words such as "first" and "second" do not necessarily limit the difference.

[0051] It should be noted that, in this application, words such as "exemplary" or "for example" are used as examples, illustrations or illustrations. Any embodiment or design described herein as "exemp...

Abstract

The embodiment of the invention discloses a method for generating an HDR image and electronic equipment, and the method comprises the steps: the method is applied to the electronic equipment comprising a first camera and a second camera, the electronic equipment displays a first interface, and the first interface comprises a preview image and a first control; detecting a first operation on the first control; in response to the first operation, the first camera collects a first original image, and the second camera collects a second original image; performing first processing on the first original image to obtain a first image; performing second processing on the second original image to obtain a second image; according to the method, the first image and the second image are subjected to weighted fusion to obtain the HDR image, the images with different exposure coefficients are synchronously acquired based on the double cameras, and the HDR image is obtained based on fusion of the images with different exposure coefficients, and the images are acquired synchronously, so that exposure duration difference does not exist, and the problem of motion ghosting can be effectively avoided.

Description

technical field [0001] The present application relates to the field of image processing, and in particular to a method and electronic equipment for generating HDR images. Background technique [0002] Dynamic range (dynamic range, DR) is used in many fields to represent the ratio of the maximum value to the minimum value of a variable. In a digital image, the dynamic range represents the ratio between the maximum brightness and the minimum brightness within the displayable range of the image, that is, the number of grayscale divisions of the image from "brightest" to "darkest". The larger the dynamic range of an image, the richer the brightness level it can represent, and the more realistic the visual effect of the image. A high dynamic range (high dynamic range, HDR) image (hereinafter referred to as an HDR image) can provide more dynamic range and image details, and thus can better reflect visual effects in a real environment. [0003] At this stage, the imaging process ...
