Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 複雑な計算や装置を必要とせずに、簡易に傾 きを検出し補正することが可能な原稿角度補正方法及び 装置を提供する。 【解決手段】 原稿を読み取り画像データを生成する読 み取り手段10と、画像データの傾きを検出する傾き検 出手段20と、画像データの傾きの補正を行う傾き補正 手段30,50,60と、を備え、前記傾き検出手段 は、画像データから原稿の縁を抽出して原稿の傾き角を 求め、前記傾き補正手段は、原稿の傾き角に応じた変倍 処理とデータシフト処理を行う。 (57) [Problem] To provide a document angle correction method and apparatus capable of easily detecting and correcting a tilt without requiring complicated calculations and devices. SOLUTION: There are provided reading means 10 for reading a document and generating image data, inclination detecting means 20 for detecting the inclination of the image data, and inclination correcting means 30, 50, 60 for correcting the inclination of the image data. The skew detecting means extracts the edge of the document from the image data to determine the skew angle of the document, and the skew correcting means performs a scaling process and a data shift process according to the skew angle of the document.
