  • Publication number: 20230049993
    Abstract: The present disclosure provides a pixel structure including a plurality of sub-pixels. Each sub-pixels of at least one color includes four target sub-pixels. Four target sub-pixels of the same sub-pixel are separated by a first separation region extending along a first direction and a second separation region extending along a second direction. At least a part of a side of the first separation region and at least a part of another side of the first separation region are facing, parallel to and spaced from each other by an interval of a first width, at least a part of a side of the second separation region and at least a part of another side of the second separation region are facing, parallel to and spaced from each other by an interval of a second width, and the first and second widths are smaller than an interval between adjacent sub-pixels.

  • Patent number: 11539823
    Abstract: A muffling device includes an acquisition circuit, configured to obtain reference sound wave information of a user. The muffling device includes a modulation circuit, configured to analyze an acoustic wave characteristic of the reference sound wave information to obtain a characteristic parameter of the reference sound wave information. The muffling device includes a muffling circuit, configured to generate compensated sound wave information according to the characteristic parameter of the reference sound wave information. The muffling device includes a correction circuit, configured to compare muffed sound wave information superimposed by the compensated sound wave information and the reference sound wave information with the reference sound wave information, and feed back a comparison result to the muffling circuit. The muffling circuit can adjust the compensated sound wave information according to a fed back comparison result.

  • Patent number: 9225879
    Abstract: A method for video sequential alignment is provided. The method includes inputting a first video sequence and a second video sequence, and extracting features of the first video sequence and the second video sequence. The method also includes generating an expanded path using a hierarchical sequential alignment algorithm and generating masks containing search space using keyframe matching. Further, the method includes calculating the lowest path cost within search space to find a minimal alignment path using a block A* algorithm and outputting a final alignment result after applying the block A* algorithm to search space.
