Described herein are systems and methods of converting media dimensions. A device may identify a set of frames from a video in a first orientation as belonging to a scene. The device may receive a selected coordinate on a frame of the set of frames for the scene. The device may identify a first region within the frame including a first feature corresponding to the selected coordinate and a second region within the frame including a second feature. The device may generate a first score for the first feature and a second score for the second feature. The first score may be greater than the second score based on the first feature corresponding to the selected coordinate. The device may crop the frame to include the first region and the second region within a predetermined display area comprising a subset of regions of the frame in a second orientation.

Described are methods, systems, and computer-readable media to automatically crop videos using personalized parameters. Some implementations include a computer-implemented method that comprises obtaining an input video, determining a per-frame crop score for one or more candidate crop regions in each frame of the input video, generating a face signal for the one or more candidate crop regions, adjusting each per-frame crop score based on the face signal, determining a minimal cost path that represents crop region locations based on motion cost and the adjusted per-frame crop score, generating crop keyframing corresponding to the crop region locations along the minimal cost path, wherein the crop keyframing includes a start frame, an end frame, and crop region location, and outputting a modified video that has one or more of an output aspect ratio or an output orientation that is different than a corresponding aspect ratio or an orientation of the input video.

A display control apparatus displays an image on a display unit in such a manner that, in a second shooting, the image to be displayed on the display unit is reduced to a smaller size in a case where a frame display setting is ON than in a case where the frame display setting is OFF, and, in a first shooting, the image to be displayed on the display unit in the case where the frame display setting is ON is not reduced to a size smaller than that of the image to be displayed on the display unit in the case where the frame display setting is OFF, the frame display setting being a display setting for information.

An automated method and apparatus are provided for identifying when a first video is a content-identical variant of a second video. The first and second video each include a plurality of image frames, and the image frames of either the first video or the second video include at least one black border. A plurality of variants are generated of selected image frames of the first video and the second video. The variants are then compared to each other, and the first video is identified as being a variant of the second video when at least one match is detected among the variants.

Black borders are detected in an image frame using a grey scale image of the image frame, and an edge image of the image frame. Candidate black borders are identified using maximum grey scale values associated with rows and columns of pixels of the grey scale image of the image frame, and then validated using a sum of grey scale values associated with rows and columns of pixels in the edge image of the image frame. If the validation fails, it is presumed that no black border exists.

A camera system captures an image in a source aspect ratio and applies a transformation to the input image to scale and warp the input image to generate an output image having a target aspect ratio different than the source aspect ratio. The output image has the same field of view as the input image, maintains image resolution, and limits distortion to levels that do not substantially affect the viewing experience. In one embodiment, the output image is non-linearly warped relative to the input image such that a distortion in the output image relative to the input image is greater in a corner region of the output image than a center region of the output image.

A calibration step is disclosed for use with a system and a method for creating a wide-screen picture-dominance effect in an auditorium located in a motion-picture theater. This is accomplished by an operator viewing a test image or images of horizontal and vertical lines projected onto a deeply-curved screen in said auditorium and adjusting the projection of said test image or images until the horizontal and vertical lines in said image or images appear straight and orthonormal, with the result that viewers watching motion pictures in said auditorium will observe images that appear wider than the physical confines of the auditorium in said theater.

Disclosed are a multimedia device including a flexible display and controlling method thereof. The present invention includes a guide bar, a flexible display configured to be rolled up on an outer circumference of the guide bar, the flexible display having a first region rolled up on the outer circumference of the guide bar and a second region not rolled up on the outer circumference of the guide bar, a receiving unit configured to receive a content and metadata corresponding to the content from a source device, and a control unit adjusting a vertical width of the second region of the flexible display in accordance with a preset condition.

The disclosure provides a display device and a display image rotation adapting method. A rotating component may be controlled to rotate a screen into a portrait mode if a video media resource is a vertical media resource and the screen is in a landscape mode; or, the rotating component may be controlled to rotate the screen into a landscape mode if the video media resource is a horizontal media resource and the screen is in a portrait mode, so as to adapt to an aspect ratio corresponding to the video media resource.

Systems and methods are provided for displaying a first portion of a video, the first portion comprising a subset of the video that fits in a display area of a computing device. The systems and methods further detect movement of the computing device during playback of the first portion of the video, calculate a rotation of the display of the first portion of the video based on a direction of the movement, and cause the display of the first portion of the video to rotate relative to the direction of movement to display a second portion of the video, the second portion comprising a subset of the video that is associated with the direction of movement and that was at least partially not visible in the first portion of the video when displayed in the display area of the computing device.
