Abstract: A comb light source and spectrometer is disclosed. The comb light source and spectrometer can include a plurality of light emitters, where each light emitter can be configured to emit light included in a plurality of wavelength bands. Each wavelength band can be separated from an adjacent wavelength band by a noise band. Due to the separated wavelength bands for a light emitter, any signal received outside of the one or more wavelength bands can originate from noise (e.g., drift, ambient light, electrical noise), thereby enhancing signal analysis and noise rejection. In some examples, the comb light emitters can be activated sequentially such that a plurality of wavelengths across a spectrum can be measured. In some examples, the resolution and the number of spectral lines in the comb light source can be tuned by changing the properties of the quantum dots and/or increasing the number of comb light emitters.

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.

Abstract: A projector includes a measurement unit and a correction parameter generation unit. The measurement unit measures a color of image light of the image formed on a projection surface in terms of a plurality of colors constituting an RGB color system and a Z value in an XYZ color system. The correction parameter generation unit generates a correction parameter based on a first measurement value and a second measurement value. The first measurement value measured by the measurement unit is obtained by converting a measurement value of the color in the RGB color system into the color in the XYZ color system. The second measurement value measured by the measurement unit is a value in the XYZ color system. The measurement unit includes an optical filter having transmittance characteristics corresponding to spectral characteristics of blue light, in a wavelength range of a color light in the RGB color system.

Abstract: An imaging device includes a light splitting unit which splits first light from a subject into second light and third light, first and second imaging units, and an arithmetic unit. The first light includes the second light having infrared light and at least one of green light and blue light, and the third light having red light or the green light. The first imaging unit includes a first and a second light reception regions. The first light reception region generates at least one of the group consisting of a B signal according to the blue light and a G signal according to the green light. The second light reception region generates an IR signal according to the infrared light. The arithmetic unit generates a visible light image signal from the R signal, the G signal, and the B signal and generates an infrared light image signal from the IR signal.

Abstract: A modular device includes base and color sensing portions. The color sensing portion has a face, a controlled light source offset from the face to define an interior, the face configured to engage a target surface about a perimeter of the device housing wherein ambient light is restricted from entering the interior. A color sensor receives light reflected from the target surface and generates output signals representative of a surface color. The base portion communicates with the color sensor and a user device having a hosted program which generates a user interface enabling users to provide control input for the color sensor. The program further receives the output signals from the color sensing device and displays a first image of the detected color, and displays a second image of a user-selected color beside the first image. Color data values are further displayed corresponding to the difference between displayed colors.

Abstract: Information is encoded in an image signal by exploiting spectral differences between colors that appear the same when rendered. These spectral differences are detected using image sensing that discerns the spectral differences. Spectral difference detection methods include using sensor-synchronized spectrally-structured-light imaging, 3D sensors, imaging spectrophotometers, and higher resolution Bayer pattern capture relative to resolution of patches used to convey a spectral difference signal.
