    摘要： A color sensor for measuring light from a light source and the method for fabricating the color sensor. The color sensor includes a plurality of photodetectors, a plurality of primary color filters and a trim filter. Each primary color filter includes a layer of material between the light source and a corresponding one of the photodetectors. Each primary color filter preferentially transmits light in a corresponding band of wavelengths about a characteristic wavelength. The trim filter is located between the light source and the photodetectors and includes a layer of material that preferentially attenuates light at a first trim wavelength between two of the characteristic wavelengths. In one embodiment, the trim filter further preferentially attenuates light at a second trim wavelength, the first wavelength being less than one of the characteristic wavelengths and the second wavelength being greater than that characteristic wavelength.

    摘要： Method and apparatus for duplicating a target color and changing a color of an object to match the target color. A first color sensor measures the target color. A color projection mechanism selectively changes the color of the object. A color matching mechanism is coupled to the first color sensor for receiving the target color. Based on the target color, the color matching mechanism controls the color projection mechanism to change the color of the object to match the target color.

    摘要： An imaging device and method for producing an infrared (IR) filtered digital image of a scene of interest uses IR image signals derived from light transmitted through infrared pass filters of a color filter array to remove IR light components of color image signals derived from light transmitted through color pass filters of the color filter array. The color and IR image signals are generated using an image sensor that includes an imaging array and the color filter array.

    摘要： A display device for providing optical feedback includes light sources, each for emitting light in a different respective wavelength range, electro-optical elements defining pixels of an image, each for selectively passing light in one of the wavelength ranges and a sensor for measuring the intensity of light output from a portion of the electro-optical elements. To provide the optical feedback, a controller activates one of the light sources, alters those electro-optical elements within the portion of the electro-optical elements that are arranged to pass light in the wavelength range of a select one of the light source and reads out the measured intensity from the sensor. Based on the measured light intensity, the controller adjusts an illumination parameter associated with the select light source.

    摘要： A switch panel having a touch plate, light converter, and light analyzer are disclosed. The touch plate includes an optically transparent layer having first and second surfaces, and having an index of refraction greater than that of air. The touch plate conducts light of an excitation wavelength between the first and second surfaces and emits part of that light through the second surface at one of a plurality of emission locations depending on the position at which pressure is applied to the first surface. The light converter is positioned to receive the light emitted through the second surface and generates light having a plurality of distinct location-specific spectra, one of the location-specific spectra corresponding to each of the emission locations. The light analyzer generates a signal indicative of which of the location-specific spectra was generated by the light converter.
