A photographing method in a telephoto scenario, wherein the method is applied to a mobile terminal comprising a camera, and the method comprises: starting the camera by the mobile terminal, and displaying a finder frame by the mobile terminal, wherein the finder frame is used to display a first preview picture, and a zoom ratio of the camera corresponding to the first preview picture is a first magnification; receiving a first operation input by a user to increase the zoom ratio of the camera; displaying a second preview picture by the finder frame in response to the first operation, wherein a zoom ratio of the camera corresponding to the second preview picture is a second magnification, and the second magnification is greater than the first magnification; and if the second magnification is greater than or equal to a preset magnification, before the mobile terminal displays the second preview picture, performing, by the mobile terminal, first image processing on an image collected by the camera to generate the second preview picture; wherein the first image processing comprises: recognizing a target photographed object, and a background of the target photographed object based on the image collected by the camera; and adding a blurring effect to the image of the area in which the background of the target photographed object is located, characterized in that the first image processing comprises improving image sharpness of an area in which the target photographed object is located, wherein in the first image processing, the improving image sharpness of an area in which the target photographed object is located specifically comprises: recognizing a category of the target photographed object, and obtaining a first image of the target photographed object by segmenting the image collected by the camera; and inputting the first image into a neural network model corresponding to the category of the target photographed object, and outputting a second image of the target photographed object, wherein the sharpness of the second image is greater than that of the first image. starting the camera by the mobile terminal, and displaying a finder frame by the mobile terminal, wherein the finder frame is used to display a first preview picture, and a zoom ratio of the camera corresponding to the first preview picture is a first magnification;
