An image display device includes a plurality of signal input parts, a plurality of sub-controllers configured to process video signals from a plurality of signal input parts, and a controller configured to generate a display screen to be displayed on a display. The controller obtains the timing information for a video signal from the sub-controller based on the display information installed in advance.

SYSTEMS AND METHODS FOR DYNAMICALLY ADJUSTING VIDEO ASPECT RATIOS

Described herein are systems and methods for dynamically adjusting an aspect ratio of a video. Exemplary methods can include receiving (i) a video having an original aspect ratio and at least one user interface (UI) element configured to be selected by a user of the video and (ii) an aspect ratio of a display screen for presenting the video. The methods can include automatically determining a display area of the video to be presented based on (i) the default position of the at least one UI element in the video, (ii) an active area in the video, and/or (iii) a central area in the video, the display area having an aspect ratio equal to the aspect ratio of the display screen; and presenting the video display area in the display screen with the at least one UI element for at least the portion of the video.

Aspect ratio conversion with machine learning

Techniques are disclosed for converting image frames, such as the image frames of a motion picture, from one aspect ratio to another while predicting the pan and scan framing decisions that a human operator would make. In one configuration, one or more functions for predicting pan and scan framing decisions are determined, at least in part, via machine learning using training data that includes historical pan and scan conversions. The training data may be prepared by extracting features indicating visual and/or audio elements associated with particular shots, among other things. Function(s) may be determined, using machine learning, that take such extracted features as input and output predicted pan and scan framing decisions. Thereafter, the image frames of a received video may be converted between aspect ratios on a shot-by-shot basis, by extracting the same features and using the function(s) to make pan and scan framing predictions.

Intelligent video reframing

Embodiments of the present invention are directed towards reframing videos from one aspect ratio to another aspect ratio while maintaining visibility of regions of interest. A set of regions of interest are determined in frames in a video with a first aspect ratio. The set of regions of interest can be used to estimate an initial camera path. An optimal camera path is determined by leveraging the identified regions of interest using the initial camera path. Sub crops with a second aspect ratio different from the first aspect ratio of the video are identified. The sub crops are placed as designated using the optimal camera path to generate a cropped video with the second aspect ratio.

Moving video tags

A method causes a display device to simultaneously display at least the following: a video depicting an item in a scene and a tag in a first position on the video. The tag is associated with the item depicted in the video. The tag includes text information associated with the item depicted in the video. The method also causes the tag to undergo motion relative to at least a portion of the video scene from the first position to a second position different from the first position, while causing the display device to display the video and the tag on the video.

CONVERSION BETWEEN ASPECT RATIOS IN CAMERA

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.

Devices, Methods, and Graphical User Interfaces for Capturing and Recording Media in Multiple Modes

A device displays a camera user interface for recording media images in a plurality of media recording modes. While displaying the camera user interface, the device captures media with one or more cameras. In response to capturing the media, in accordance with a determination that the captured media is consistent with a first media recording mode, the device displays a first prompt in the camera user interface that prompts a user to take one or more actions associated with the first media recording mode; and in accordance with a determination that the captured media is consistent with a second media recording mode, the device displays a second prompt in the camera user interface that prompts the user to take one or more actions associated with the second media recording mode, where the first media recording mode is different from the second media recording mode.
