  • Publication number: 20210216843
    Abstract: The present invention provides a contactlessly readable tag with which both a small tag size and long-distance readability can be achieved, a method for manufacturing the contactlessly readable tag, an identification device, and an identification information determination system. In this tag 200, the arrangement pattern of metal parts in a metal pattern layer 202 of this tag 200 is associated with identification information, and when irradiating the tag 200 with electromagnetic waves, the identification information can be read on the basis of the information of the electromagnetic waves reflected by the tag 200, and the metal pattern layer 202 is provided closer to a reading surface side of the tag 200 than a buffer layer 201 having at least a single layer.

  • Publication number: 20210055216
    Abstract: The objective of the present invention is to provide a device for calculating a gloss value using a gloss value calculating method having an enhanced correlation with an impression of gloss sensed visually by a person. The present invention for achieving this objective relates to a gloss value calculating device. The gloss value calculating device comprises: a peak calculating unit which uses distribution information of brightness or reflection intensity with respect to a light reception angle obtained by measuring reflected light resulting from the reflection of measuring light radiated at an object, to obtain the peak height and spread of the brightness or the reflection intensity in the distribution information; and a gloss value calculating unit which calculates a gloss value represented by a ratio of the peak height to the peak spread.

  • Publication number: 20200400565
    Abstract: A color tone quantification device for a glossy color, in which the correlation with the color tone of the glossy color visually perceived by humans is further enhanced, is provided. The device comprises a coefficient calculation unit that calculates a coefficient calculated in consideration of a spatial distribution which is to be used to correct the chromaticity measured by a method including a specular reflection component obtained by measuring the reflection light obtained by reflection of measurement light to an area of an object; a chromaticity calculation unit that calculates an effective chromaticity obtained by weighting the chromaticity measured by the method including the specular reflection component with the coefficient calculated by the coefficient calculation unit; and an output unit that outputs the effective chromaticity as a stimulus value representing a glossy color of the area in a color space.
