  • Publication number: 20210407461
    Abstract: A feeling is given that a stationary object is moving even when an apparent motion is not established between the stationary object and luminance varying areas. An image generation device generates video including a stationary object area, at least one luminance varying area located along a contour of the stationary object area, and a background area other than the stationary object area and the luminance varying area. Luminance of the luminance varying area varies with time in a luminance range based on luminance of the stationary object area and luminance of the background area.

  • Publication number: 20210398486
    Abstract: A proximity sensor comprises a light emitting element configured to emit light; a synchronization signal input unit configured to be input with a synchronization signal which is output from a display device and which indicates a rewrite timing of an image displayed on a display screen; and an emission controller configured to control emission of the light from the light emitting element, wherein the emission controller is configured to cause the light emitting element to start the emission of the light at a start timing set based on the rewrite timing at which rewriting of one of a plurality of scanning lines of the image is caused to start in the specific display region, and an emission time of the light from the light emitting element, and the emission controller is configured to cause the light emitting element to end the emission of the light before the rewrite timing comes.

  • Publication number: 20210398293
    Abstract: A technique that automatically adjusts a motion given to a projection target using a perceptual model is provided. A motion vector generation apparatus includes a first parameter generation unit that generates a first parameter that is a parameter for scaling a motion vector based on a perceptual difference between a projection result reproduction image which is an image that is obtained when a projection target onto which a projection image obtained based on the motion vector has been projected is photographed and a warped image which is an image generated by distorting an image obtained when the projection target is photographed by a perceptual amount of motion perceived when the projection result reproduction image is viewed, and a motion vector reduction unit that scales the motion vector using the first parameter.

  • Publication number: 20210256887
    Abstract: To create an illusion that a target which has an arbitrary contour shape and which is actually not moving is perceived to be moving. An object including a final target that is equivalent to an object obtained by a superposition of three objects of a target, a dark object, and a light object with approximately the same shape, a superposition of two objects of a target and a dark object with approximately the same shape or approximately similar shapes, or a superposition of two objects of a target and a light object with approximately the same shape or approximately similar shapes is arranged in a background of which luminance periodically varies over time. However, luminance of the dark object is lower than luminance of the target, luminance of the light object is higher than the luminance of the target, and the superposition described above is an incomplete superposition in which a part of the dark object and/or a part of the light object is hidden by the target.

  • Publication number: 20210258547
    Abstract: The color and the brightness of a transparent material perception to be given to an image are independently operated using simple image processing techniques. Using a plurality of different deformation maps that have elements corresponding to respective pixels deriving from an original image and have low-spatial frequency components, the elements indicating a moving direction and a moving amount of the corresponding pixels, the pixels deriving from the original image are moved in a moving direction by a moving amount, the moving direction and the moving amount being specified by the elements corresponding to the respective pixels, to obtain a plurality of modulated images.

  • Publication number: 20210150796
    Abstract: A visual perception of an arbitrary transparent material is imparted to an arbitrary image. In accordance with each element of each deformation map included in a sequence of deformation maps that correspond to a time series, each element of a target image is moved to obtain each deformed image of the time series. Each element of each of the deformation maps indicates a movement direction and a movement amount of each pixel of the target image corresponding to the element.

  • Publication number: 20210125305
    Abstract: A video of a shadow is automatically generated to create an illusion that a region included in a real object floats above a background and an apparent height of the region with respect to a background region changes with time. A video generation device receives input of a dark region image including a dark region that is a spatial region corresponding to a target object and is darker than a background, and control information for specifying a motion to be given to the dark region, and obtains and outputs a video including a shadow region is obtained and output. The shadow region is obtained by performing mask processing on a motion region obtained by giving the motion to the dark region according to the control information. The mask processing replaces pixels of a mask region at a spatial position corresponding to the target object with pixels brighter than the motion region.

  • Publication number: 20110298595
    Abstract: A technique capable of recognizing a usage state of a power of a user, curbing additionally needed power consumption is provided. Scanning bit stream data containing information regarding scan frequencies and an initial-stage power of each of the frequencies is outputted from an output part, decomposed into data of respective scan frequencies, transformed to time series digital data in an IFFT module, transformed to scanning analog data by D/A transform in an AFE, and transmitted to a power line. Reflected analog data received from the power line is transformed by A/D transform in the AFE, transformed to frequency series reflected spectrum data in the FFT module, and sent to a check part. The check part checks combination of attenuation rates of respective scan frequencies against registered pattern data registered in a pattern correspondence relationship storage part, and outputs a related connection state of an outlet as a checked result.
