    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: 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.
