The present disclosure provides a method and an apparatus for zooming video images, and belongs to video playing technology. The method may include: receiving a zoom request for zooming a current video frame while a video is being played; determining a zoom center point and a zoom ratio according to the zoom request; determining a target image area to be displayed in a playing window from the current video frame after zooming according to the zoom center point and the zoom ratio; and rendering, in the playing window, image content within the target image area of video frames subsequent to the current video frame when playing subsequent video frames. As such, a user is enabled to selectively zoom video frames according to the needs, thus can clearly see details in the video.

An image processing includes: a unit that calculates a feature amount of main image data; a unit that calculates a feature amount of sub image data or resized sub image data; an adjustment unit that performs image quality adjustment on the resized sub image data so that a difference between a feature amount of the adjusted sub image data and the feature amount of the main image data is smaller than a difference between the calculated feature amount of the sub image data and the feature amount of the main image data; and a unit that generates display image data from the main image data and adjusted sub image data according to display mode information. The sub image data include plural content items. The adjustment unit updates the feature amount of the main image data used in the adjustment, at the timing of change of the content item.

Methods and devices for processing images are disclosed. In various embodiments, an electronic device for processing images may include: a display module to display a first image and a control module to control a process of receiving a second image different from the first image. The control module may be capable of altering the second image in accordance with a block area arranged on the first image, determining an output sequence for the first image and the altered second image, and alternatingly displaying the first image and the altered second image according to the output sequence.

A display apparatus transmits a picture acquisition request for getting picture information to an external image apparatus connected through a predetermined interface to the display apparatus from the external image apparatus at predetermined intervals and gets a plurality of pieces of picture information from the external image apparatus to be displayed. The plurality of pictures may be switched at predetermined intervals, for example, to be displayed, so that the plurality of pictures may be displayed in a so-called slide show manner. A plurality of pictures for thumbnail may be produced from the plurality of pieces of picture information and be arranged together to be displayed in one picture screen of a display device.

An apparatus and method for receiving and displaying a television signal and a data signal in a mobile terminal. The mobile terminal includes a display unit with a video data display area and a user data display area. The mobile terminal determines in a standby mode whether it is set to a television mode or communication mode. If the mobile terminal is set to the television mode, it controls a tuner to select a desired television channel. The mobile terminal stores video data of a current frame received over the selected channel and user data corresponding to the selected channel in a memory unit, outputs video data of a previous frame stored in the memory unit to the video data display area of the display unit in a frame period and then outputs the user data stored in the memory unit to the user data display area of the display unit upon completing the output of the video data of the previous frame. In the communication mode, the mobile terminal stops the operation of the tuner and displays user data generated in the communication mode in the video data display area and user data display area.

An interaction method, an interaction apparatus, and an electronic device are provided. The method includes: determining, in response to detecting a predefined size transformation operation, target transformation information of a target video based on whether a current size of the target video is a preset anchor point size, where the target video is a video played in a video play area; and transforming the target video based on the target transformation information, and playing the transformed target video.

In one aspect, a method includes receiving, by a content-management system and from a content-presentation device, a request for supplemental content, such as a replacement advertisement. The content-management system may then determine a technical characteristic of the content-presentation device and select supplemental content based at least in part on at least the determined technical characteristic of the content-presentation device. The content-management system may then cause the selected supplemental content to be transmitted to the content-presentation device to facilitate the content-presentation device performing a content modification operation.

A transmitting device for communicating via a multimedia communication link includes a compression circuitry that receives blanking period data corresponding to blanking states of video blanking periods. The compression circuitry compresses the blanking period data into compressed blanking period data. The transmitting device also includes an interface that transmits signals corresponding to the compressed blanking period data via one or more multimedia channels of the multimedia communication link.

A method for processing video frames, a video processing chip, and a Motion Estimation/Motion Compensation (MEMC) chip are provided. The method performed by the video processing chip includes obtaining multiple video frames and adjusting each video frame from a first resolution to a second resolution. The method also includes inserting at least one invalid frame into the multiple video frames according to a second frame rate, so that a frame rate of a transport frame stream is the second frame rate; and sending the transport frame stream to an MEMC chip. The video processing chip and the MEMC chip may perform transmission of a frame stream according to an interface frequency corresponding to a resolution and a frame rate that are agreed upon.

An image processing device processes a first sub-image of an image split into sub-images. Each sub-image is displayable by a display device. The image processing device is associated with a first display device and connects to a source device through a first network and to another image processing device through a second network. The image processing device includes first and second receiving units and a generating unit. The first receiving unit receives the first sub-image from the source device via the first network. The second receiving unit receives, via a second network, at least one part of at least one second sub-image to be displayed by another display device, wherein the received at least one part is adjacent to the received first sub-image. The generating unit generates a first clustered sub-image to be displayed by the first display device, based on the received first sub-image and adjacent part.
