Abstract

A color arrangement checking device stores a full-color document in which elements of each color are placed on a page, detects at least a color and a size of the elements for each page of the document, adds up the size of the elements for the whole page by the color which is output as an occupancy ratio, and determines whether or not at least one of brightness and saturation exceeds a predetermined color threshold value for each color of the elements. The color arrangement checking device determines whether or not the occupancy ratio by the color of the elements, which assume the color, of which at least one of the brightness and the saturation is determined to exceed the color threshold value, as an attribute, exceeds a predetermined occupancy threshold value, and outputs the elements which assume the color, of which the occupancy ratio is determined to exceed the occupancy threshold value, as the attribute.

Claims

1. A color arrangement checking device comprising:

a document storage unit storing a full-color document in which elements of each color are placed on a page;

an attribute detection unit detecting at least a color and a size of the elements for each page of the document;

an occupancy ratio calculation unit adding up the size of the elements for the whole page by the color and outputting this as an occupancy ratio;

a color arrangement checking unit determining whether or not at least one of brightness and saturation exceeds a predetermined color threshold value for each color of the elements;

an occupancy ratio checking unit determining whether or not the occupancy ratio by the color of the elements, which assume the color, of which at least one of the brightness and the saturation is determined to exceed the color threshold value, as an attribute, exceeds a predetermined occupancy threshold value; and

a result output unit outputting the elements which assume the color, of which the occupancy ratio is determined to exceed the occupancy threshold value, as the attribute.

2. The color arrangement checking device according to claim 1, wherein the attribute detection unit detects positions of the elements for each page of the document,

wherein the color arrangement checking device further comprises a superimposition analysis unit determining whether or not there is the other element superimposed on an upper side of the element based on the position and the size of the page, and

wherein the occupancy ratio calculation unit subtracts an area of the element on an upper side which has been determined to be superimposed and the color of which is set from an area of the element on a lower side to output the occupancy ratio.

3. The color arrangement checking device according to claim 1, wherein the result output unit outputs the element together with a plurality of attribute information items including at least the color and the size.

4. The color arrangement checking device according to claim 1, further comprising a color changing unit changing at least one of hue, the brightness, and the saturation of the element output from the result output unit.

5. An information storage medium storing a computer program for causing the color arrangement checking device according to claim 1 to execute:

a document storage process of storing a full-color document in which elements of each color are placed on a page;

an attribute detection process of detecting at least a color and a size of the elements for each page of the document;

an occupancy ratio calculation process of adding up the size of an element for the whole page by the color and outputting this as an occupancy ratio;

a color arrangement checking process of determining whether or not at least one of brightness and saturation exceeds a predetermined color threshold value for each color of the elements;

an occupancy ratio checking process of determining whether or not the occupancy ratio by the color of the elements, which assume the color, of which at least one of the brightness and the saturation is determined to exceed the color threshold value, as an attribute, exceeds a predetermined occupancy threshold value; and

a result output process of outputting the elements which assume the color, of which the occupancy ratio is determined to exceed the occupancy threshold value, as the attribute.

6. A data processing method of the color arrangement checking device according to claim 1, comprising:

a document storage operation of storing a full-color document in which elements of each color are placed on a page;

an attribute detection operation of detecting at least a color and a size of the elements for each page of the document;

an occupancy ratio calculation operation of adding up the size of the elements for the whole page by the color and outputting this as an occupancy ratio;

a color arrangement checking operation of determining whether or not at least one of brightness and saturation exceeds a predetermined color threshold value for each color of the elements;

an occupancy ratio checking operation of determining whether or not the occupancy ratio by the color of the elements, which assume the color, of which at least one of the brightness and the saturation is determined to exceed the color threshold value, as an attribute, exceeds a predetermined occupancy threshold value; and

a result output operation of outputting the elements which assume the color, of which the occupancy ratio is determined to exceed the occupancy threshold value, as the attribute.
