Resolution conversion system and method

A display device that interpolates inputted original image data and displays converted image data thus interpolated, comprising:

• a display unit that displays said converted image data;
• an image processing unit that generates an interpolation pixel based on said original image data, inserts said interpolation pixel into said original image data, and generates said converted image data;
• and,
• a display control unit that outputs said converted image data to said display unit, wherein,
• said image processing unit determines a luminance of at least one interpolation pixel to be inserted between two pixels of said original image data, said luminance having a value larger than a value on a straight line connecting values of luminance of said two pixels of said original image data.

• and,
• a display control unit that outputs said converted image data to said display unit, wherein,
• said image processing unit determines a gray-scale level of at least one interpolation pixel to be inserted between two pixels of said original image data, said gray-scale level having a value smaller than a value on a straight line connecting values of gray-scale level of said two pixels of said original image data.

• and
• a display control unit that outputs said converted image data to said display unit, wherein,
• said image processing unit determines, based on two pixels of said original image data, reference values of said interpolation pixel to be inserted between said two pixels of said original image data, and
• a value of said interpolation pixel is selected so as to be inserted between said two pixels of said original image data, out of said reference values, in accordance with a function, which is set in such a manner that at least one gray-scale value of said interpolation pixel has a value larger than values on a straight line connecting said two pixels of said original image data, in a graph having pixel locations on a horizontal axis and gray-scale values on a vertical axis.
