JPS6428791A - Character row detector - Google Patents

Abstract

PURPOSE:To detect a character row with a required minimum processing time from document picture data having the arbitrary width of the character row, a row interval and the arbitrary inclination of the character row by providing a character row inclination detecting means, a character row width and row interval approximating means or the like. CONSTITUTION:The character row inclination detecting means 2 detects the actual inclination in a character row direction of the document picture data to a prescribed scanning direction on the document picture data inputted through a document picture data memory 1. The character row width and row interval approximating means 3 obtains the approximate value of the width and the row interval of the character row in the document picture data. A belt shape area width deciding means 4 decides the actual inclination of the character row and the width of a belt shape area based on the approximate value of the width and the row interval of the character row and outputs to a partial row detecting means 5. Thereby, the character row can be correctly detected with the required minimum processing time even at the time of having the inclination in the character row to various documents different in the row or the row interval of the character row through the means 5 and a partial row coupling means 6.
