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

The invention discloses a picture-in-picture display method and device, electronic equipment and a computer readable storage medium. The method comprises the steps of obtaining original image data; processing the original image data by using at least two image processing algorithms to obtain at least two corresponding to-be-output images; determining a target image from the at least two to-be-output images; generating a corresponding picture-in-picture image by using a non-target image in the to-be-output image; superposing the picture-in-picture image with the target image to obtain an output image; according to the embodiment of the invention, the picture-in-picture image is superposed with the target image to obtain the output image, so that the output image can enable the user to obtain more information than only viewing the target image, the information types obtained by the user are enriched, and the identification of the target is facilitated. In addition, only one path of original image data is matche
