Color measurement system to correct color data corresponding to a ratio of detected distance to a reference distance

摘要

A color measuring device includes a housing; a sensor unit configured to capture an image of a region, the sensor unit being held to the housing; an illumination light source configured to illuminate the region, the illumination light source being held to the housing; a detecting unit configured to detect a distance between predetermined two points from image data of the region obtained by the sensor unit; a correcting unit configured to correct the image data including a subject whose color is to be measured according to a ratio of the detected distance to a reference distance; and a calculating unit configured to calculate a colorimetric value of the subject based on the corrected image data.

1. A color measuring device, comprising:
a housing; a reference chart held to the housing; a sensor to capture, from inside the housing, image data of a two-dimensional region that includes the reference chart and an area outside the housing, the sensor being held by the housing, the captured image data including subject image data of a subject whose color is to be measured, the subject being located in the area outside the housing; an illumination light source to illuminate the region from inside the housing, the illumination light source being held by the housing; a detector to detect a distance between predetermined two points within the subject image data obtained by the sensor; a correcting unit configured to correct the subject image data obtained from the sensor according to a ratio of the detected distance to a reference distance; and a calculating unit configured to calculate a colorimetric value of the subject based on the subject image data corrected by the correcting unit.
