Image processing apparatus, image forming apparatus, simplified color chart, and non-transitory computer readable medium storing image processing program
An image processing apparatus includes a processor configured to generate a second color chart from a first color chart. The second color chart includes multiple color samples selected from multiple color samples included in the first color chart, and the second color chart is generated in such a manner that a color sample included in the second color chart is located in the second color chart at a position at least maintaining a partial-adjacency relationship in the first color chart.
1. An image processing apparatus comprising:
a processor configured to
generate a preliminary simplified color chart including a plurality of color samples from a basic color chart having a plurality of color samples;
identifying column-end color samples in the preliminary simplified color chart;
extracting neighboring color samples from the basic color chart;
locating the neighboring color samples next to the column-end color samples in the preliminary simplified color chart to generate a regular simplified color chart,
wherein all of the color samples of the regular simplified color chart are selected from the color samples of the basic color chart, the regular simplified color chart being generated in such a manner that a color sample included in the regular simplified color chart is located in the regular simplified color chart at a position at least maintaining a partial-adjacency relationship in the basic color chart.
2. The image processing apparatus according to claim 1 ,
wherein the partial-adjacency relationship represents a relationship in which two color samples are adjacent to each other in one of two directions that are a main scan direction and a sub-scan direction that is perpendicular to the main scan direction, the two directions being defined for a scan of the regular simplified color chart.
3. The image processing apparatus according to claim 2 ,
wherein a color sample in the regular simplified color chart is located at one end in the one of the two directions in the regular simplified color chart, a color sample in the basic first color chart corresponds to the color sample in the regular simplified color chart, and a color sample located at a position adjacent to the color sample in the basic color chart is located at a position adjacent to the color sample in the regular simplified color chart.
4. An image forming apparatus comprising:
a processor configured to
operate based on a color chart generated by the image processing apparatus according to claim 1 , and
form the regular simplified color chart on a recording medium.
5. A non-transitory computer readable medium storing a program causing a computer to execute a process for image processing, the process comprising:
generating a preliminary simplified color chart including a plurality of color samples from a basic first color chart having a plurality of color samples;
identifying column-end color samples in the preliminary simplified color chart;
extracting neighboring color samples from the basic color chart;
locating the neighboring color samples next to the column-end color samples in the preliminary simplified color chart to generate a regular simplified color chart,
wherein all of the color samples of the regular simplified color chart are selected from the color samples of the basic color chart, the regular simplified color chart being generated in such a manner that a color sample included in the regular simplified color chart is located in the regular simplified color chart at a position at least maintaining a partial-adjacency relationship in the basic color chart.
