An image processing method and apparatus, and a method and apparatus for training an image processing model, which relates to the technical field of image processing. The image processing method includes: acquiring an original diffraction image; inputting the original diffraction image into an image processing model (S304); and by using the image processing model, performing restoration processing to the original diffraction image, to obtain a target standard image corresponding to the original diffraction image.

An electronic device includes a UDC and a UDC controller configured to determine an optimal number of frames required to be captured for a scene to compensate at least one parameter to optimize an output media using the UDC, obtain a multi-frame fusion media by performing at least one multi-frame fusion on the determined optimal number of frames, perform a light source spread correction on the multi-frame fusion media, and optimize the output media based on the light source spread correction on the multi-frame fusion media.

One example provides a computing device including a first portion including a first display, a second portion including a second display and a camera, the second portion connected to the first portion via a hinge, a hinge angle sensing mechanism including one or more sensors, a logic device, and a storage device holding instructions executable by the logic device to execute a camera application and to receive sensor data from the one or more sensors, based at least in part on the sensor data received from the one or more sensors, determine a device pose, output the camera application to the first display when the device pose is indicative of the camera being world-facing, and output the camera application to the second display when the device pose is indicative of the camera being user-facing.

A device comprising at least one camera, a display, a memory and a processor, the memory storing instructions which, when executed by the processor, cause the device to: display, using the display of the device, a content to be reviewed by the user; detect, using the camera of the device, user's eyes; detect, using the camera of the device, user's eye movements; determine, based on the detected user's eye movements, whether the user has reviewed the content.

An under-display camera is positioned underneath a display of a mobile device. The under-display camera captures an image using light passing through a portion of the display. The mobile device displays a display image on the display, the display image based on the image. The mobile device displays an indicator overlaid over the display image on an indicator area of the display that overlaps with the portion of the display. The indicator may identify the position of the camera. The mobile device can compensate for occlusion of the camera by continuing to display a previous display image if a more recently captured image includes an occlusion. The mobile device can give users alternate ways to select areas of the display image to avoid camera occlusion, for instance using hardware buttons and/or touchscreen interface elements.

An electronic viewfinder unit includes a finder unit and a base member. The finder unit includes a display unit, an eyepiece portion, and a lens holding member holding a lens that guides a light flux emitted from the display unit to the eyepiece portion. The base member includes a guide member configured to guide the electronic viewfinder unit to a housed state and a protruding state. The base member includes a holding portion and a turning member. The holding portion is provided with a first holding member and a second holding member that face each other with an optical axis of the lens in between. The turning member has one end held by the first holding member and another end held by the second holding member, and is turnable about an axis orthogonal to the optical axis of the lens.

A method for detecting interference patterns for an under-screen camera, a compensation method and a circuit system are provided. The circuit system includes an image-processing circuit and an under-screen camera module. The under-screen camera module captures an image by a lens through a glass substrate of a display module. After receiving the image, the image-processing circuit detects and compensates an interference pattern. In the method, multiple reference points are set in the image, and a brightness average value and a brightness target value for each of the reference points are obtained for calculating an area brightness ratio of the reference points. A binarized image is then obtained. The interference pattern is determined according to symmetrical characteristics of the binarized image. A target matrix is decided for compensating the interference pattern according to weights of all of the reference points of the image.
