In accordance with an embodiment, a method of operating an electronic device comprising a screen, a first camera, and a second camera, includes: detecting that a zoom ratio gradually changes within a first ratio range, wherein the zoom ratio in the first ratio range is less than an optical zoom ratio of the second camera, and a ratio difference between the zoom ratio within the first ratio range and the optical zoom ratio of the second camera is less than a first value; cropping an image captured by the first camera to obtain a preview image whose field of view (FOV) size gradually changes; and displaying on the screen, the preview image whose FOV size gradually changes.

Photographing method and electronic device

An image segmentation method includes: encoding an original image containing a target object based on a prior knowledge vector, to obtain a target feature map, the prior knowledge vector comprising a plurality of prior knowledge weights each representing accuracy of a corresponding rater labeling a region of an object in an image; decoding the target feature map, to obtain a first segmented image of the original image, the first segmented image indicating a target region in which the target object is located in the original image; performing image reconstruction on the first segmented image based on the prior knowledge vector, to obtain labeled segmented images, wherein one labeled segmented image corresponds to one prior knowledge weight and indicates a target region labeled by a corresponding rater; and processing the target feature map based on the labeled segmented images, to obtain a second segmented image of the original image.
