Some embodiments of the application disclose a method of previewing an image on a terminal, including: starting at least one camera of a rear dual camera of the terminal, controlling the at least one camera to enter a low-power monitor state; obtaining brightness information and color temperature information of the current scene using the at least one camera in the low-power monitor state; updating in real time automatic exposure parameters of the current scene using the obtained brightness information, and updating in real time color temperature parameters of the current scene using the obtained color temperature information; obtaining an image of the current scene using a camera upon reception of an instruction for starting the camera; correcting color temperature and brightness of the obtained image using the color temperature and automatic exposure parameters of the current scene updated in real time; and outputting the corrected image as a preview image.

Terminal, and apparatus and method for previewing an image

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

A method of starting a camera, a user equipment and a storage medium are provided. A memory in the user equipment is additionally utilized to store calibrated OTP data therein so that the calibrated OTP data stored in the memory can be written directly into a register of an optical sensor of the camera each time the user equipment accesses the camera to thereby avoid OTP data calibration each time the user equipment accesses the camera, and shorten a period of time for the user equipment to access the camera and a period of time for the camera to start while avoiding an overly amount of calibration calculations, lowering a load on a kernel of the user equipment and improving the experience of a user.
