  • Patent number: 11955097
    Abstract: A shift register includes stages each constituted by a unit circuit provided with a thin-film transistor (separation transistor) that separates a control node into an output-side first control node and an input-side second control node and a capacitor whose first end is connected to the second control node. The thin-film transistor (separation transistor) has a control terminal that is supplied with a high-level DC power supply voltage. Typically, the channel width of a thin-film transistor (first output control transistor) that controls output from a unit circuit is ten or more times greater than the channel width of the thin-film transistor (separation transistor).

  • Publication number: 20230316463
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for using a filter for temporal noise reduction. In some implementations, image data for a series of frames, including a first input frame followed by a second input frame, of a video is obtained. A first output frame resulting from noise reduction processing for the first input frame and a measure of variance associated with a portion of the first output frame is obtained. An interpolation setting for noise reduction processing of a portion of the second input frame is determined. A second output frame is generated by interpolating the portion of the second input frame with the corresponding portion of the first output frame.
