  • Video display device, television receiver, transmitting device, control program, and recording medium
    Patent number: 10536663
    Abstract: A technology of preventing feeling of a viewer on brightness from significantly changing when content is switched is provided. A video display device (1) includes a calculation unit (23) that calculates video feature relating to a display video, and a mute video display unit that displays a mute video posterior to a first display video, in which luminance of the mute video is luminance corresponding to a value of the video feature relating to the first display video.
    Type: Grant

  • IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, CONTROL PROGRAM, AND RECORDING MEDIUM
    Publication number: 20190058843
    Abstract: A technique for preventing a significant change of viewer's perception of brightness for each content. An image processing device (1) includes a calculation unit (6) configured to calculate a video feature from a parameter in a video signal for transmission and an adjustment unit (8) configured to adjust the parameter such that the video feature calculated by the calculation unit is approximated to a prescribed reference value.
