  • Publication number: 20200333666
    Abstract: A display device includes a power consumption calculation unit configured to calculate total power consumption of a plurality of light sources in displaying an input video; a ratio determining unit configured to determine a scale-down ratio or a cut-out ratio for the video based on a relationship between a prescribed maximum display luminance for a given pixel and a preset, specified display luminance that is a maximum value of display luminance for a faithful luminance display, the prescribed maximum display luminance being predetermined so as to be achievable at the total power consumption calculated by the power consumption calculation unit and a display control unit configured to process the video in accordance with the scale-down ratio or cut-out ratio determined by the ratio determining unit.

  • Publication number: 20200106930
    Abstract: The invention has an object to reduce computing costs in object identification in a video to below conventional levels. A signal processing unit for processing a video composed of a plurality of frames includes: an object identification unit configured to identify an object represented in the video; and a window specification unit configured to specify, based on a position in an (N+1)-th frame of the video of a representation of the object that appears in an N-th frame, an identification target region to be subjected to object identification in the (N+1)-th frame by the object identification unit, where N is a natural number.

  • Patent number: 10471355
    Abstract: A more effective image is presented to a third person in accordance with the progress of a prescribed story of a game in which a virtual object is generated. An MR game device (3) includes a spectator-viewing-intended image synthesis unit (353) that generates a spectator viewpoint image of a virtual space containing an image of the virtual object and an image of a competitor as viewed from a virtual space viewpoint of a spectator in accordance with the progress of the prescribed story.

  • Patent number: 9916803
    Abstract: A display device includes a display panel including a first display region and a second display region and boundary correction circuits that perform tone correction on display data in such a manner that a correction amount for the display data to be written to a first pixel adjacent to a boundary between the first display region and the second display region and a correction amount for the display data to be written to a second pixel not adjacent to the boundary are different from each other.

  • Patent number: 9479682
    Abstract: A video signal processing device according to an embodiment of the present invention includes a motion vector detection unit and a plurality of interpolated image generation units. The motion vector detection unit detects an interpolated motion vector which represents a motion between a first broad image and a second broad image. Each of the interpolated image generation units generates an interpolated partial image corresponding to a divided area by using a first partial image of a first frame, a second partial image of a second frame, and the interpolated motion vector.
