    摘要: PROBLEM TO BE SOLVED: To provide a photometric system which reduces errors, even in the measurement of narrow-band light such as monochromatic light and performs measurements of chroma values or the like with high accuracy.
    SOLUTION: A chromameter 1 comprises a polychromater 4 as a spectral optical system including a light-receiving sensor array 43, a signal processing circuit 5, and an arithmetic and control unit 6. The arithmetic and control unit 6, using a light-receiving signal and a predetermined weighting coefficient, performs calculations for determining the characteristics of light to be measured, on the basis of predetermined spectral responsivity. The spectral responsivity of each light-receiving sensor, constituting the light-receiving sensor array 43, is selected to be B≥5 nm and A/B=1.5 to 4.0, where A is the half-value width of the spectral responsiveness and B is the center wavelength interval thereof.

    摘要: PROBLEM TO BE SOLVED: To simplify a measuring operation and improve measuring efficiency in a monocular type measuring device in which a luminous flux entering from a single light receiving optical system is split by a luminous flux splitting means, and they are guided to a finder optical system and a photometric means, thereby making it possible to check a target subject through a finder by the use of a light receiving optical system that is the same as the light receiving optical system used for the measurement. SOLUTION: The opening/closing of a shutter 57 interposed in the finder optical system 53 in order to prevent inverse light entering from a finder eyepiece part 65 is controlled by a finder control circuit 60 depending on whether the level of the inverse light entering, detected by an outside light monitor sensor 62, exceeds a permissible threshold or not. This makes it possible to correctly measure luminance without being affected by the inverse light entering. This also eliminates the need for an operator to perform the operation of opening or closing the shutter 57 in order to realize such accurate measurement every time measurement is carried out. Accordingly, the measuring operation is simplified and measuring efficiency can be improved. Additionally, since the shutter 57 is shielded only when the measurement is likely to be affected, measurement with the device held with hands can be increased. COPYRIGHT: (C)2005,JPO&NCIPI

    SOLUTION: A light-dispersing part 22 and a light-receiving part 20 are integrated in such a way as to be rotated on an axis as an axis of rotation intersecting a geometric plane at right angles and passing through the center A of an opening. A prescribed region is scanned in detail (light is received at a plurality of positions) with respect to a position corresponding to a reflecting direction of specularly reflected light prior to the measurement of values of reflection characteristics. A measuring position for computing values of reflection characteristics is determined on the basis of the position of specularly reflected light to perform measuring operations at the measuring position.
