Abstract

A colorimetric system includes a comparison processing unit that performs a process of a comparison between a color value of a color that was subjected to colorimetry by a colorimetric unit that performs colorimetry and a color value of a reference color, wherein the comparison processing unit performs a display process of making notification of a comparison processing result and a color to be subjected to colorimetry next that is a color that is not subjected to colorimetry.

Claims (33)

1 . A colorimetric system comprising:

a colorimetric sensor that performs colorimetry based on a color group of reference colors arranged in a specific order; and

a processor that compares a color difference between a color value measured by the colorimetric sensor and a color value of a reference color, and determines whether the color difference is smaller than a given value, wherein

the processor sets a completion flag for a measured color,

when the processor detects a plurality of colors without the completion flag within the color group, the processor determines a target color to be subjected to colorimetry next among the plurality of colors without the completion flag, according to the specific order, and performs a display process by displaying a user interface, in which a next colorimetry of the target color and a color that was subjected to colorimetry immediately before are displayed, and

the color difference is displayed in the user interface.

2 . The colorimetric system according to claim 1 , wherein

when the processor detects the plurality of colors without the completion flag after a color at an end of the specific order in the color group was subjected to colorimetry, the colorimetric system notifies of the color without the completion flag as the target color to be subjected to colorimetry next.

3 . The colorimetric system according to claim 1 , wherein

when the processor detects the plurality of colors without the completion flag that include an earlier color and a later color in the specific order than a color measured most recently, the processor determines the later color as the target color.

4 . The colorimetric system according to claim 1 , wherein

the processor performs a display process of displaying in the user interface by adding an icon indicating that colorimetry was performed with respect to the color that was subjected to colorimetry.

5 . The colorimetric system according to claim 1 , wherein

the processor performs a display process of displaying in the user interface so as to indicate that colorimetry was performed by forming a predetermined figure with the color that was subjected to colorimetry and the reference color.

6 . The colorimetric system according to claim 1 , wherein

the processor is further configured to receive operations from a user, and

when the color to be subjected to colorimetry next is displayed, the processor receives a predetermined operation that allows a color to be subjected to colorimetry further next to be selected.

7 . The colorimetric system according to claim 6 , wherein

the operations include an operation of skipping a colorimetry order as the predetermined operation.

8 . The colorimetric system according to claim 1 , wherein

the processor performs a display process of displaying in the user interface a message for allowing an end of colorimetry of the color group to be accepted without performing colorimetry of the color that is not subjected to colorimetry.

9 . A terminal device comprising:

a processor that acquires a color value of a color that was subjected to colorimetry from a colorimeter that performs colorimetry based on a color group of reference colors arranged in a specific order, wherein

the processor compares the color value of the color that was subjected to colorimetry with a color value of a reference color and notifies a user of a comparison processing result,

the processor sets a completion flag for a measured color, and

when the processor detects a plurality of colors without the completion flag within the color group, the processor notifies a target color to be subjected to colorimetry next among the plurality of colors without the completion flag, according to the specific order, and performs a display process by displaying a user interface, in which a next colorimetry of the target color and a color that was subjected to colorimetry immediately before are displayed, and

the comparison processing result is displayed in the user interface.

10 . A non-transitory computer-readable storage medium storing a program, the program causing a computer to execute as:

a processor that acquires a color value of a color that was subjected to colorimetry from a colorimetric unit that performs colorimetry based on a color group of reference colors arranged in a specific order, wherein

the processor compares the color value of the color that was subjected to colorimetry by the colorimetric unit with a color value of a reference color,

the processor sets a completion flag for a measured color, and

when the processor detects a plurality of colors without the completion flag within the color group, the processor notifies a target color to be subjected to colorimetry next among the plurality of colors without the completion flag, according to the specific order, and performs a display process by displaying a user interface, in which a next colorimetry of the target color and a color that was subjected to colorimetry immediately before are displayed, and

a comparison processing result is displayed in the user interface.
