Abstract: This application relates to the field of terminals, and provides a method for switching cameras and an electronic device. The method is applicable to an electronic device, the electronic device includes a camera module, the camera module includes a first camera and a second camera, and the method includes: running a camera application in the electronic device; displaying a first image; determining whether a first distance and a second distance meet a first preset condition, where the first distance and the second distance indicate an object distance between the electronic device and a to-be-photographed object, the first distance is an object distance that is obtained based on a parameter of the first camera, and the second distance is an object distance that is obtained based on a parameter of the second camera; and displaying a second image when the first distance and the second distance meet the first preset condition.

Abstract: Disclosed are an image processing method and an electronic device. The image processing method includes: displaying a first screen, where the first screen includes a first control; detecting a first operation on the first control; determining a first mapping in a three-dimensional lookup table in response to the first operation, where the first mapping is corresponding to the first control; converting a to-be-processed image in a first color space into a first image in a second color space, where the to-be-processed image is an image obtained in the first color space; processing the first image according to the first mapping to obtain a second image; and converting the second image in the second color space into a third image in the first color space.

Abstract: An image processing method and an electronic device are disclosed. The image processing method includes: displaying a first screen in a first shooting mode, where the first screen includes a first control; detecting a first operation on the first control; in response to the first operation, determining a first mapping in gamma processing and a second mapping in a two-dimensional lookup table, where the first mapping corresponds to the first control, the second mapping corresponds to the first control, and the first mapping is associated with the second mapping; obtaining a to-be-processed image; and processing the to-be-processed image based on the first mapping and the second mapping to obtain a first image. On the basis of the technical method of this application, computational load of electronic devices during image processing can be effectively reduced.
