    Abstract: A color luminance meter 1 is provided with a polychrometer 4 as a spectral optical system including a light receiving sensor array 43, a signal processing circuit 5 and an operation control unit 6. The operation control unit 6 carries out calculations to obtain characteristics of a measurement light based on a specified spectral responsitivity, using light reception signals and specified weighting coefficients. The spectral responsitivities of light receiving sensors constructing the light receiving sensor array 43 are selected such that B≧5 nm and A/B lies within a range of 1.5 to 4.0 when A, B denote the half power band width of the spectral responsitivities and a center wavelength interval of the spectral responsitivities. Accordingly, there can be provided a light measuring apparatus capable of maximally suppressing errors to highly precisely measure color luminance values and the like even in a measurement of a light lying in a narrow band such as a monochromatic light.

    Abstract: Optical feedback for controlling color of light from a light source is provided. Incident optical energy of the light is detected as a function of discrete steps of wavelength. For each discrete step of wavelength, an X, Y and Z tristimulus subvalue is produced. All the X, Y and Z tristimulus subvalues for all the discrete steps are summed together to produce an X, Y and Z tristimulus value for the light. The X, Y and Z tristimulus values are used as feedback in controlling color of the light generated by the light source.

    Abstract: In the color information measuring device, the print object information measuring device, the printing device and the electronic equipment, three light fluxes of mutually different wavelengths applied to a measurement object from a red LED, a green LED and a blue LED of a light-emitting part have a common illumination area on the measurement object. The common illumination area on the measurement object contains such an observation area on the measurement object that a reflected ray is made to be incident on a photodiode via a condenser lens and a slit member. Therefore, the common illumination area in which three light fluxes of different wavelengths overlap with one another can reliably be made to be an observation area, so that intensities of a plurality of reflected rays of different wavelengths derived from the observation area can be observed equivalently, hence an improved measurement accuracy.

    Abstract: A colorimeter or color measuring device measures color of a sample or an object, and displays measurement value or values according to user defined index or indices, calculated by a user-defined formula. Data of the user-defined formula is read in from outside of the colorimeter and converted into a coded form which can be executed by a controller of the calorimeter. The data of the user-defined formula or the coded data is stored in the colorimeter. Accordingly, the colorimeter has good portability and convenience despite its capability of expressing the colors of various samples or objects by user-defined original index or indices.
