Abstract

An information processor includes an acquisition unit that acquires a colorimetric value from a colorimeter that scans a color chart and measures color; and an output unit that assigns a weighting value according to a position in a scanning interval of the color chart, and that outputs a weighted average value of the colorimetric value of multiple patches for a color setting value.

Claims

1. An information processor comprising:

an acquisition unit that acquires a colorimetric value from a colorimeter that scans a color chart and measures color; and

an output unit that assigns a weighting value according to a position in a scanning interval of the color chart, and that outputs a weighted average value of the colorimetric value of a plurality of patches for a color setting value.

2. The information processor according to claim 1,

wherein in a first interval including an end point of the scanning interval and shorter than the scanning interval, the output unit assigns a smaller weighting value than in a second interval adjacent to the first interval.

3. The information processor according to claim 2,

wherein in the first interval including the end point of the scanning interval and shorter than the scanning interval, the output unit assigns a larger weighting value as a position is further away from the end point.

4. The information processor according to claim 1,

wherein in addition to assigning a weighting value according to a position in the scanning interval, the output unit assigns a weighting value according to elapsed time after calibration of the colorimeter.

5. The information processor according to claim 2,

wherein in addition to assigning a weighting value according to a position in the scanning interval, the output unit assigns a weighting value according to elapsed time after calibration of the colorimeter.

6. The information processor according to claim 3,

wherein in addition to assigning a weighting value according to a position in the scanning interval, the output unit assigns a weighting value according to elapsed time after calibration of the colorimeter.

8. The information processor according to claim 4,

wherein the output unit assigns a smaller weighting value as elapsed time after calibration increases.

9. The information processor according to claim 5,

wherein the output unit assigns a smaller weighting value as elapsed time after calibration increases.

10. The information processor according to claim 6,

wherein the output unit assigns a smaller weighting value as elapsed time after calibration increases.

7. An information processor comprising:

an acquisition unit that acquires a colorimetric value from a colorimeter that scans a color chart and measures color; and

an output unit that assigns a weighting value according to elapsed time after calibration of the colorimeter, and that outputs a weighted average value of the colorimetric value of a plurality of patches for a color setting value.

11. The information processor according to claim 7,

wherein the output unit assigns a smaller weighting value as elapsed time after calibration increases.

12. A non-transitory computer readable medium storing a program causing a computer to execute a process for color measurement, the process comprising:

acquiring a colorimetric value from a colorimeter that scans a color chart and measures color; and

assigning a weighting value according to a position in a scanning interval of the color chart, and outputting a weighted average value of the colorimetric value of a plurality of patches for a color setting value.
