Picture-in-picture display method and apparatus, and electronic device and readable storage medium

Abstract

A picture-in-picture display method and apparatus, and an electronic device and a computer-readable storage medium. The method comprises: acquiring original image data; respectively processing the original image data by using at least two image processing algorithms, so as to obtain at least two corresponding images to be output; determining a target image from the at least two images to be output; generating a corresponding picture-in-picture image by using a non-target image from among the images to be output; and superimposing the picture-in-picture image onto the target image, so as to obtain an output image. An output image is obtained by means of superimposing a picture-in-picture image onto a target image, such that a user can acquire more information from the output image than that acquired by only viewing the target image, thereby enriching types of information acquired by the user, and facilitating the identification of a target. In addition, in the present application, a picture-in-picture image is generated by only using one path of original image data in combination with a plurality of image processing algorithms, without the need of using a multi-functional hardware device to acquire a plurality of original signals.
