Abstract
It is one object of the present invention to obtain a clear scaled image, without impairing the rough shape of fonts or the like, on a graphics screen that is handled by an information display device such as an LCD panel or a projector, and that includes a lot of stepped edges like thin lines. According to the present invention, an image processing apparatus for applying a resolution conversion on original image data to generate a converted image scaled by rational number or integral number of times, comprises: an original image data input unit for inputting the original image; an algorithmic nonlinear processing unit for generating a first converted image data, wherein connect relations are maintained for a line width included in the original image data even after the resolution conversion; a multirate processing unit for generating a second converted image data, wherein the resolution conversion is performed on the original image data while maintaining a rough shape of the line width; and a mixing unit for mixing the first converted image data and the second converted image data according to the weighting by a weight determination unit
