Abstract: A linearization correction section (104) performs linearization correction of the output of an image sensor (8) on the basis of linearization correction data held in a linearization correction data holding section (102). A luminance unevenness correction section (108) corrects the luminance unevenness of the linearization-corrected output of the image sensor on the basis of the luminance unevenness data held in a correction data holding section (106). The luminance of a specimen having a surface of uneven lightness is measured using an image sensor (8). The output of each pixel of the image sensor (8) is subjected to linearization correction and luminance unevenness correction, and a reflectance calculating section (110) calculates the integral of the reflectance in the surface of the specimen. A determining section (114) calculates the density of a sample of the specimen by applying the integral of the reflectance to the working curve data held in a working curve data holding section (112)

Abstract: A system (200) and method (800) for determining whether a sample object (203) has a color that is within a predetermined range is provided. The system (200) includes a light source (201) capable of projecting lights having different light wavelength spectrum upon the sample object (203). A controller (222) causes the light source (201) to project a first light wavelength spectrum upon the sample object (203), then another, then another, and so forth. While each light is projecting upon the object, a monochromatic image capture device (202) captures an image having luminous intensity information. The luminous intensity information, or a subset thereof selected by an image selection tool (232) is then compared to the statistical range, which is derived from a plurality of images taken of a reference object (403).

Abstract: Above a measuring object (2), an LEDs (4) for use in light irradiation and a CMOS area sensor (8) with an image-forming lens (6) interpolated in between are installed. In order to detect the quantity of light from the LEDs (4), a photodetector (10) is further placed. A personal computer (28) carries out a linearizing process which, upon variation of the quantity of light, corrects the output of the area sensor (8) so as to make the output from the area sensor (8) proportional to the output of the photodetector (10), and a light-irregularity correction process which, when a flat plate having even in-plane density is measured as the measuring object (2), corrects the resulting output of each pixel in the area sensor (8) that has been corrected by the linearizing process to have in-plane evenness. It becomes possible to achieve a convenient two-dimensional reflection factor measuring method which does not need any mechanical driving system.

Abstract: 直線化補正部(104)はイメージセンサ(8)の出力を直線化補正データ保持部(102)に保持された直線化補正データに基づいて直線化補正し、光むら補正部(108)は直線化補正されたイメージセンサ出力を光むら補正データ保持部(106)に保持された光むら補正データに基づいて光むらを補正する。反射率算出部(110)は面内に濃淡を持つ試験片を測定したときのイメージセンサ(8)の各ピクセル出力で、直線化補正と光むら補正が施された出力を用いて、その試験片の面内における反射率の積分値を算出する。定量部(114)は反射率算出部で求められ積分された反射率に検量線データ保持部(112)の検量線データを適用して試験片の試料濃度を算出する。
