    Abstract: A linearizing correction unit (104) carries out a linearizing correction process on the output of an image sensor (8) based upon linearizing correction data stored in a linearizing correction data holding unit (102), and a light-irregularity correction unit (108) carries out a light-irregularity correction process on the image sensor output that has been subjected to the linearizing correction process based upon light-irregularity correction data stored in a light-irregularity correction data holding unit (106). A refection factor calculation unit (110) calculates an integral value of the in-plane reflection factor of a test piece by using the output that has been subjected to the linearizing correction and light-irregularity correction with respect to pixel outputs of the image sensor (8) obtained when the test piece having in-plane density irregularities is measured. A quantifying unit (114) applies calibration curve data of a calibration-curve-data holding unit (112) to the integrated reflection factor obtained by the reflection factor calculation unit so that a sample density of the test piece is calculated.

    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.
