An image preview method, apparatus, and terminal are disclosed to provide a technical solution in which a background blurring effect with respect to a current scene can be previewed in real time. A terminal device synchronously obtains preview images of a current scene from different angles in a dual-camera photographing preview mode by using a dual-camera module, calculates, in the preview images based on a phase difference generated by a distance and an angle of the dual-camera module, a depth of field of each pixel unit included in a preview image, obtains a foreground depth of field of a preset target area in the preview image, and determines, in the same preview image, an area including all pixel units having a depth of field beyond a range as a background area. The terminal device also performs blurring processing on the background area by using a preset blur coefficient, and outputs an image including the target area and a blurring-processed background area as a real-time preview image of the current scene.

Image preview method, apparatus and terminal

The present disclosure relates to a image data generating method and device. The device may be configured to obtain a plurality of frames of images of a scene including at least one object, each of the plurality of frames of images is associated with a character distance of a plurality of character distances of the electronic device. For each of the plurality of frames of images, device may determine a target image area, wherein the target image area is an image area on which an object in the scene is sharply focused; and set a focus area in the target image area. Finally, the device may generate an all-focused image by combining the plurality of frames of images, wherein each of the at least one object is sharply focused.

Image data generating method and apparatus

Embodiments of the present disclosure provide a method for controlling the brightness of a shot image by controlling an exposure parameter used when the image is taken on the basis of the distribution condition of detail features comprised in each brightness class area of an image frame in a preview image frame. The method includes the operations of acquiring a preview image frame, and determining the brightness level n of each pixel in the preview image frame; dividing the preview image frame into M class areas according to the determined brightness level n of each pixel; determining an exposure adjustment level required when the preview image frame is taken according to the distribution condition of detail features comprised in each class area in the preview image frame; and adjusting a pre-acquired exposure parameter according to the determined exposure adjustment level, and taking an image according to the adjusted exposure parameter.

Method and device for image taking brightness control and computer readable storage medium

There are provided a method and apparatus for displaying a preview image and a storage medium. The method includes: acquiring frames of image data when there is a need to display a preview image; weighting and processing a frame of image data currently acquired and frames of image data acquired recently for a number M of times to obtain the preview image, wherein M is a positive integer; and displaying the preview image.

Method and apparatus for displaying preview image and storage medium

The disclosure relates to the field of image processing technologies and particularly to a method and device for determining an image offset and a storage medium. A method according to an embodiment of the disclosure includes: dividing equally an acquired target image into a number M*N of first sub-areas and dividing equally an acquired image to be aligned into a number M*N of second sub-areas; determining an area offset between each first sub-area and a corresponding second sub-area; and determining an image offset between the target image and the image to be aligned according to the determined multiple area offsets.
