    Abstract: One or more display color characteristics of an electronic device are managed using a light detecting sensor configured to output multiple color channels in a predefined color space. The light detecting sensor in the electronic device senses ambient light and outputs measurements in visible color channels of the predefined color space to characterize the sensed ambient light. A ratio of one or more measurements of one of the visible color channels to one or more measurements of another of the visible color channels is determined. At least one light source generating at least a portion of the sensed ambient light is classified based at least in part on the determined ratio, wherein the determined ratio indicates a color temperature component of the sensed ambient light. The one or more display color characteristics of the electronic device are adjusted based at least in part on the classifying operation.

    Abstract: A color measuring apparatus includes an opening portion that is provided in a bottom portion of the apparatus and takes light from a measurement target into the apparatus, an incident light processing unit that processes light that enters the apparatus through the opening portion, a housing that covers an apparatus internal unit including the incident light processing unit, at least one protrusion member that is configured to switch between a first state in which the protrusion member protrudes from a bottom surface of the housing and a second state in which the protrusion member does not protrude from the bottom surface of the housing, and at least one pressing member that presses the protrusion member in a protruding direction from the bottom surface of the housing.

    Abstract: An integrated radiation sensor for color matching functions comprises a plurality of color matching channels, each color matching channel comprising a radiation sensing element and an associated optical filter defining a spectral sensitivity profile corresponding to a color matching function. The sensors comprise a plurality of compensation channels, each compensation channel comprising a radiation sensing element and an associated optical filter defining a spectral sensitivity profile for use in compensating a color sensed by the color matching channels. The spectral sensitivity profile of each compensation channel substantially corresponds to a mean of an upper deviation spectra and a lower deviation spectra, wherein the upper deviation spectra corresponds to a spectral sensitivity profile of a typical color matching channel increased by a fixed deviation in wavelength and the lower deviation spectra corresponds to the spectral sensitivity profile of the typical color matching channel decreased by the fixed deviation in wavelength.

    Abstract: A device for detecting the color of leather hides, which is installable on machines and/or in plants for processing and/or managing leather hides, includes a surface for supporting a leather hide of which the color is to be detected, a light source emitting a light radiation of known spectral composition onto the leather hide, an optical sensor capturing the light radiation emitted from the light source and reflected from the leather hide, a member positioned at the optical sensor and keeping the distance constant between the optical sensor and the leather hide, an optical filter associated to the optical sensor to extract the values of the chromatic components of the light radiation captured by the optical sensor, and a processing unit receiving the values of the chromatic components and comparing those values with preset reference values and/or calculating and identifying the corresponding color.

    Abstract: A spectroscopic camera includes a wavelength variable interference filter, and an image sensor that receives light which is transmitted through the wavelength variable interference filter. Measurement is implemented a plurality of times by causing measurement light to be incident to the wavelength variable interference filter and changing the wavelength of light that is transmitted by the wavelength variable interference filter. Reflectance based on the intensity of light when a first pixel of the image sensor receives light of a target wavelength, is predicted in the respective plurality of repetitions of measurement on the basis of a light reception central wavelength of light that the first pixel receives, and reflectance that is calculated on the basis of the intensity of light that is received by the first pixel.
