Abstract: A calculation device comprises a color evaluation unit that acquires a sensor color and four or more reference colors from photography data from a measurement time when an indication object was photographed in a second photography environment; determines coefficients for color conversion between a first and the second photography environments based on the amount of change from color information for the reference colors in the first photography environment, which has been read from a calculation device storage unit, to color information for the reference colors in the second photography environment, which has been acquired from the photography data; and uses the sensor color acquired from the photography data from the measurement time and the color conversion coefficients to correct the sensor color to the color that would have been photographed in the first photography environment by solving a conversion formula including terms representing an affine transformation consisting of translation.

Abstract: The present invention provides a system and method by which the quality of a plurality of articles having the same management code assigned can be managed while in distribution. Input devices receive input of data of management codes of articles at distribution sites of the articles, and transmit to a management device the management code data, the date and time at which the management code data has been inputted, and data of the input site. the management device: drives, for all combinations of management codes and the input sites among the data which has been transmitted from the input devices, lead data having the earliest input date and time; compares the input dates and times of the lead data for all combinations of any two different input sites, for each of the management codes among all of the management codes; treats article distribution routes from the input site having a late input date and time to the input site having a nearly input date and time as being non-existent; and derives, as candidates for article distribution routes, the combinations other than those for which no distribution route exists from among all combinations of any two different input sites.
