Abstract:
1. An image processing apparatus for expanding/reducing input image data supplied thereto, for each area of the image data, the image processing apparatus comprising: a high frequency (HF) component detector that detects HF components of the input image data and creates HF component detection information that shows in which pixel in the input image data the HF component exists; a smoothing processor that generates smoothed image data by smoothing the input image data; an image data selection unit that selects, based on the HF component detection information, the smoothed image data and the input image data, and calculates a weighted average of the smoothed image data and the input image data, thereby generating smoothed-HF-component image data; a partial magnification/reduction controller that creates partial magnification/reduction control information that designates positions of pixels in image data obtained after expanding/reducing the input image data for each area of the image data; and a pixel data generator that generates pixel data for the pixel positions designated based on the partial magnification/reduction control information in the smoothed-HF-component image data, by using data of pixels in a neighborhood of the designated pixel positions, the HF component detector including:
