Abstract

Abstract Translated from Japanese (57)【要約】 (修正有) 【目的】 高品位な縦横2次元の任意変倍処理を可能と するもので、入力の2値画像を多値化し、変倍処理を施 し、多値エンジンで印字することで上記画質劣化を解決 することができる画像処理装置を提供する。 【構成】 2値画像に像域分離処理を施す2値像域分離 手段401と、文字、線画領域と認識された画像に対して はエッジ補間型の多値化処理を行い、写真またはグラフ ィック画像と認識された領域に対してはアベレージング ・フィルタで多値化する多値化手段402とを備えた。 (57) [Summary] (Modified) [Purpose] A high-quality vertical and horizontal two-dimensional arbitrary scaling process is possible. The input binary image is multi-valued, and the scaling process is applied to the multi-level engine. Provided is an image processing device capable of solving the above-mentioned image quality deterioration by printing with. A binary image area separation means 401 for performing image area separation processing on a binary image, and edge interpolation type multi-valued processing for an image recognized as a character or line drawing area, and a photographic or graphic image. The region recognized as is provided with multi-value quantization means 402 that multi-values with an averaging filter.
