Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 低解像情報から高解像情報に変換する際に、 補間ぼけを生じることなく、任意の倍率で良好な解像度 変換ができる画像処理装置を提供する。 【構成】 入力端子100より入力した低解像情報と、 注目画素に相当する線形補間手段101で補間された (N×M)画素の補間情報を基にエッジ作成手段102 においてエッジを作成する。エッジ作成は注目画素の周 辺画素から最大値と最小値を注目画素の濃度が保存され るように(N×M)画素内に配置する。配置後の画像情 報は、線形補間情報との適応的な配分比率で加算合成し たり、平滑化手段を施すことによって、高品位な高解像 情報に変換される。 (57) [Summary] [Purpose] When converting from low resolution information to high resolution information, Provided is an image processing device capable of excellent resolution conversion at an arbitrary magnification without causing interpolation blur. [Structure] Low-resolution information input from the input terminal 100, The edge creating unit 102 is based on the interpolation information of the (N × M) pixels interpolated by the linear interpolation unit 101 corresponding to the pixel of interest. Create an edge at. In the edge creation, the maximum value and the minimum value from the peripheral pixels of the target pixel are arranged in (N × M) pixels so that the density of the target pixel is preserved. The image information after the arrangement is converted into high-quality and high-resolution information by adding and synthesizing the image information with an adaptive distribution ratio with the linear interpolation information or applying a smoothing means.
