  • Patent number: 10169881
    Abstract: A general purpose device, system, and program perform colorimetric analysis by automatically comparing the color of an object to be analyzed with reference information. The device includes an imaging unit that takes images of the object to be analyzed; a memory unit that stores reference information of color information of the object in accordance with properties of the object; a conversion unit that makes the color space of the image data and the color space of the reference information the same by converting the color spaces when the color space of the image data of the object and the color space of the reference information are different; a determination unit that determines the properties of the object by comparing the color information of the image data and the color information of the reference information in a common color space; and a display unit that displays the determination results.

  • Publication number: 20160321825
    Abstract: To provide an apparatus, a system, and a program that can easily detect an image region where retroreflected light is recorded without being influenced by a neighboring object. In one embodiment, a measuring apparatus (1) includes an imaging unit (11), a converter (141) that converts first image data captured by the imaging unit using light emission for photography and second image data captured by the imaging unit without using the light emission for photography to luminance values, a differential processor (142) that calculates a difference between a first luminance value based on the first image data and a second luminance value based on the second image data for each pixel and generates an output image visually representing a region where the difference is present based on an obtained differential image, and a display unit (16) that displays the output image.

  • Publication number: 20140153090
    Abstract: The present application provides a projection system by which constraints placed on space use of a user can be reduced. The projection system includes: a projector and a screen. The screen includes a first film for transmitting image light incoming from the projector and a second film for transmitting the image light transmitted through the first film. A pattern for refracting or reflecting the image light toward the second film is formed on a light entrance face of the first film receiving the image light. The incident angle of the image light entering the first film is not less than 20 degrees.
