IMAGE GENERATING DEVICE, IMAGE GENERATING METHOD AND PRINTING DEVICE
First Claim
1. An image generating device for generating an image including a gradation in which a color changes from a center of the gradation through multiple areas, comprising:
- an acquisition unit that acquires parameters representing a gradation pattern, the parameters specifying the center of the gradation and a shape of the gradation;
a symmetry judgment unit that judges whether or not a gradation symmetry is satisfied, wherein the gradation symmetry is judged to be satisfied in the case where the shape of the gradation specified by the parameters has line symmetry or point symmetry and the center of the gradation is on a symmetry axis of the line symmetry or at the center of the point symmetry;
an area determination unit that determines a partial area usable for generating a whole area of the gradation by use of the gradation symmetry, if the gradation symmetry is judged to be satisfied;
a drawing unit that draws the gradation in the partial area based on the parameters acquired by the acquisition unit; and
a gradation development unit that develops the gradation drawn in the partial area into the whole area of the gradation using the gradation symmetry.

Abstract
An image generating device for generating a gradation in which the color value changes from a center of the gradation through multiple areas includes an acquisition unit that acquires parameters representing a gradation pattern including the center and shape of the gradation, a symmetry judgment unit that judges whether the gradation symmetry is satisfied (condition that the shape has line symmetry or point symmetry and the gradation center is on a line symmetry axis or at the center of point symmetry), an area determination unit that determines a partial area usable for generating a whole gradation using the gradation symmetry if the gradation symmetry is judged to be satisfied, a drawing unit that draws the gradation in the partial area based on the parameters, and a gradation development unit that develops the drawn gradation into the whole gradation using the gradation symmetry.

6. A printing device comprising an image generating unit that generates an image including a gradation in which a color changes from a center of the gradation through multiple areas and a printing unit that prints the image generated by the image generating unit on a print medium, wherein the image generating unit includes:
-
an acquisition unit that acquires parameters representing a gradation pattern, the parameters specifying the center of the gradation and a shape of the gradation; a symmetry judgment unit that judges whether or not a gradation symmetry is satisfied, wherein the gradation symmetry is judged to be satisfied in the case where the shape of the gradation specified by the parameters has line symmetry or point symmetry, and the center of the gradation is on a symmetry axis of the line symmetry or at the center of the point symmetry; an area determination unit that determines a partial area usable for generating a whole area of the gradation by use of the gradation symmetry, if the gradation symmetry is judged to be satisfied; a drawing unit that draws the gradation in the partial area based on the parameters acquired by the acquisition unit; and a gradation development unit that develops the gradation drawn in the partial area into the whole area of the gradation using the gradation symmetry. - View Dependent Claims (7, 8, 9, 10)

11. An image generating method for generating an image including a gradation in which a color changes from the center of a gradation through multiple areas, comprising:
-
an acquisition step of acquiring parameters representing a gradation pattern, the parameters specifying the center of the gradation and a shape of the gradation; a symmetry judgement step of judging whether or not the gradation symmetry is satisfied, wherein the gradation symmetry is judged to be satisfied in the case where the shape of the gradation specified by the parameters has line symmetry or point symmetry, and the center of the gradation is on a symmetry axis of the line symmetry or at the center of the point symmetry; an area determination step of determining a partial area usable for generating a whole area of the gradation by use of the gradation symmetry if the gradation symmetry is judged to be satisfied; a drawing step of drawing the gradation in the partial area based on the parameters acquired by the acquisition step; and a gradation development step of developing the gradation drawn in the partial area into the whole area of the gradation using the gradation symmetry. - View Dependent Claims (12, 13, 14, 15)
