Claim Text:
1. An image processing device including an edge enhancement section configured to perform edge enhancement by adding a shoot component in a frame constituting an image, the image processing device comprising: a calculating section configured to calculate, for each of pixels constituting the frame, a luminance difference between a pixel and another pixel adjacent to the pixel, and to calculate a first ratio which is a ratio of pixels whose luminance difference is greater than or equal to a first threshold, the edge enhancement section performing the edge enhancement in such a way that the magnitude of the shoot component to be added is inversely proportional to the magnitude of the first ratio, wherein: the calculating section further calculates a second ratio and a third ratio, the second ratio being a ratio of pixels whose luminance difference is (i) greater than or equal to a second threshold which is smaller than the first threshold and (ii) less than the first threshold, and the third ratio being a ratio of pixels whose luminance difference is less than the second threshold; and the edge enhancement section performs the edge enhancement in such a way that a shoot component, which is to be added for a frame whose second ratio is smaller than the third ratio, is smaller than a shoot component which is to be added for a frame whose second ratio is greater than the third ratio.
