PROBLEM TO BE SOLVED: To interpolate the images including color images with high efficiency by acquiring the feature value related to the interpolation processing of the image data, selecting the interpolation processing in response to the feature value and executing the interpolation processing by means of a pixel interpolation means. SOLUTION: An image data acquiring means C1 represents a digital image in pixels of a dot matrix form and acquires the image data by means of a set of data showing each pixel, and a pixel interpolation means C2 carries out the interpolation processing to increase the number of component pixels of the image data. Then a feature value acquiring means C3 acquires the feature value related to the interpolation processing of the image data. An interpolation processing selection means C4 selects the interpolation processing to obtain the optimum interpolation result in response to the said feature value, and the selected interpolation processing is carried out by a pixel interpolation means C. As a result, the image including color images can be interpolated with high efficiency. |
