Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for obtaining color mapping of a dental object.SOLUTION: The object is illuminated over at least first, second and third wavelength bands, that is, over each wavelength band at a time. An image of the dental object is captured at each wavelength band so as to form a set of images of the dental object. An image data value relating to a pixel in a captured set of images corresponds to each of the wavelength bands, and an interpolated image data value proportional to spectral reflectance of the dental object is calculated according to the obtained image data value and according to an image data value obtained from a reference object at the wavelength band. Spectral distribution data on a viewing illuminant are obtained, and a visual color of the dental object is reconstructed according to the calculated interpolated image data value and the obtained spectral distribution of the viewing illuminant.

Abstract: The combined light output (chromaticity) of a white light emitting LED luminaire is electronically controlled based on measurements by a single photodiode arranged to measure the light outputs of at least a plurality of the LEDs in the array. This is accomplished by measuring the light output of the LEDs in each color separately in a sequence of time pulses. For an array of red, green, and blue LEDs there are three time pulses in a measuring sequence. During each time pulse, the current for the color being measured is turned off. The response time of a typical photodiode is extremely short, so the measuring sequence can be performed in a sufficiently short time that an-observer will not detect it (e.g. 10 ms). Measured light outputs for the colors are compared to desired outputs, which may be set by user controls, and changes to the power supply for the color blocks are made as necessary. Chromaticity is thus automatically controlled without regard to the factors which may cause it to change. The user inputs permit varying the desired chromaticity to either warm white (more red output) or cool white (more blue output).

Abstract: PROBLEM TO BE SOLVED: To provide a photoelectric sensor capable of detecting a mark with a stable precision. SOLUTION: Prior to the action for detecting the mark 31, for each color of emitted light from the emitter element 11, the reference light receiving amount level being the light receiving amount level when the part other than the mark 31 in the sheet 30 is existing in the detection area is sampled, also the light receiving amount level of the mark 31 being the light receiving amount level is sampled, when the mark 31 of the sheet 30 is existing in the detection area for each color of emitted light from the emitter element 11. The difference of the reference light receiving amount level and the mark light receiving amount level is calculated for each color light. The ratio of the difference and the reference receiving light amount are calculated. The light of the color which represents largest ratio is selected, and projects the selected color from the light emitting element 11, during the detection action of the mark 31.
