Title:
COLOR INDEX VALUE CALCULATION SYSTEM AND COLOR INDEX VALUE CALCULATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/163249
Kind Code:
A1
Abstract:
Provided are a color index value calculation system and a color index value calculation method which assist in the cultivation of a plant by calculating, from the color of the plant, a color index value according to a growth condition. The present invention is provided with: a calculation information generation unit which generates color index value calculation information for calculating, from a color value, a color index value indicating the degree of a change in color value; a calculation information storage unit which stores the color index value calculation information generated by the calculation information generation unit; a color measurement unit which measures a color value at a prescribed part of a prescribed plant; and a color index value calculation unit which calculates and outputs the color index value on the basis of the color value measured by the color measurement unit and the color index value calculation information stored in the calculation information storage unit. Thus, the color index value, which is an index for a growth state, can be calculated, and accordingly the growth state can be objectively determined.
