Embodiment Construction

[0008] The present invention provides some methods performed by electronic devices. The electronic device can perform these methods when displaying, for example, displaying some visual data. The visual data can be video, image or graphics obtained by the electronic device from a storage medium (such as a hard disk, an optical disk, or a flash memory) or from a network (such as a TV broadcast network, a telecommunication network, a local area network or the Internet). The electronic device may be a TV, computer monitor, projector, set-top box, compact disc player, media player, desktop computer, laptop computer, tablet computer, smartphone, or video game console, to name a few examples. The electronic device may enable, disable or adjust the frequency of use of some or all of the functions used in the methods of the present invention. For example, if the visual data is video on a TV channel, the electronic device can enable these functions only during the intervals of advertis...

Abstract

An embodiment of the invention provides a method performed by an electronic device for analyzing visual data. Under the method, the electronic device first analyzes significance-indication information of an image block of visual data to determine whether the image block encompasses a significant visual pattern. The significance-indication information includes the image block's time domain information and / or color domain information. Then, if the electronic device determines that the image block encompasses the significant visual pattern, it sifts the image block out from the visual data.

Description

technical field [0001] This application relates to the processing of visual data, in particular, this application relates to a method for screening important visual styles from visual data. Background technique [0002] When visual data, such as video data, image data, or drawing data is displayed, it may exhibit patterns that arouse the potential interest of a viewer of the visual data. These patterns can be considered as important visual patterns (significant visual patterns). For the viewer to use the important visual styles that he or she sees and is interested in, he or she needs to do some manual work. For example, the viewer needs to manually click or draw a circle on an important visual style to select an area of ​​the important visual style, and these manual operations may be tedious and / or time-consuming. To avoid the inconvenience of manual manipulation, sometimes the viewer may decide to do nothing and ignore those important visual styles. Contents of the inv...
