Patent ID: 7084883

Claim:
An image processing device which by processing an image defined by a combination of unit graphic forms splits said unit graphic forms into multiple sub-unit graphic forms, the image processing device comprising: an interpolated line computation means for determining an interpolated line which is the line that interpolates a space between two vertices from an interpolation vector used for determining a line that interpolates a space between a given vertex and another vertex of vertices of said unit graphic forms and from coordinates of said vertices; and an interpolated point computation means for determining as vertices of said sub-unit graphic forms, interpolated points which are points on said interpolated line; wherein: if a unit graphic form has vertices 1 through 4 , a line segment which joins vertices 1 and 2 of said vertices 1 through 4 and a line segment that joins vertices 3 and 4 of said vertices 1 through 4 lie opposite each other, and a line segment which joins said vertices 1 and 3 and a line segment that joins said vertices 2 and 4 lie opposite each other; said interpolated line computation means determines an interpolated line 1 which interpolates a space between said vertices 1 and 2 , an interpolated line 2 which interpolates said vertices 3 and 4 , an interpolated line 3 which interpolates a space between said vertices 1 and 3 , and an interpolated line 4 which interpolates said vertices 2 and 4 , and also determines an interpolated line 5 which interpolates a space between an interpolated point on said interpolated line 1 and an interpolated point on said interpolated line 2 ; and said interpolated point computation means determines interpolated points on said interpolated lines 1 through 5 as vertices of said sub-unit graphic forms.
