Abstract

PURPOSE: To realize both of quick processing and satisfactory quality result by providing a pixel value calculation circuit which applies a plane equation to calculate a pixel value, a variable calculation circuit for the calculated pixel value, and a comparison circuit for the variable-converted value. CONSTITUTION: A pixel value calculation circuit 6 which applies the plane equation to calculate the pixel value of a position on an original graphic corresponding to each pixel on an expanded graphic, variable calculation circuits 7a and 7b which subject the calculated pixel value, and a comparison circuit 5 which compares variable converted values are provided. That is, the pixel value calculation circuit applies the plane equation to smoothly calculate the pixel value, and a picture is expanded to a precise and high-quality picture, and variable calculation circuits subject the pixel value to variable conversion, and the comparison circuit compares converted values; and the calculation processing is easily and quickly performed. Thus, the multilevels picture expansion system realizing both of the quick processing and the satisfactory quality result is obtained.
