1. A data processing apparatus comprising:
- a computer programmed to execute a process of;
obtaining measured color sample data and image data, the measured color sample data representing values obtained by measuring a plurality of color samples on a color chart with a color measuring device, the image data representing an image of the color chart and a target object captured with an image capturing apparatus;
converting captured target object color data into estimated target object color data, based on;
(i) the measured color sample data, which is the measured color sample data representing values obtained by measuring the plurality of color samples on the color chart with the color measuring device; and
(ii) captured color sample data representing values of the plurality of color samples included in the image data,the captured target object color data representing a value of a color of the target object included in the image data, the estimated target object color data representing an estimated value of the color of the target object identified if the color of the target object were measured with the color measuring device;
obtaining reference color data representing a value of a reference color of the target object;
generating evaluation data representing a result obtained by evaluating the color of the target object based on the estimated target object color data and the reference color data; and
displaying a report based on the evaluation data.

Abstract
A data processing apparatus includes an obtaining unit and a converting unit. The obtaining unit obtains measured color sample data, which represents values obtained by measuring color samples on a color chart with a color measuring device, and image data, which represents an image of the color chart and a target object captured with an image capturing apparatus. The converting unit converts captured target object color data, which represents a value of a color of the target object included in the image data, into estimated target object color data, which represents an estimated value of the color of the target object identified if the color of the target object were measured with the color measuring device, on the basis of the measured color sample data and captured color sample data, which represents values of the multiple color samples included in the image data.
