METHOD OF CORRECTING ORIENTATION OF IMAGES DURING AUTOMATIC PRINTING, A METHOD OF FORMING AN IMAGE AND AN IMAGE FORMING APPARATUS, CAPABLE OF CORRECTING AN ERROR OF ORIENTATION

摘要

PURPOSE: A method of correcting orientation of images during automatic printing, a method of forming an image and an image forming apparatus are provided to detect accurate orientation of a page.;CONSTITUTION: A text detecting unit(151) detects a text area of an inputted image. A coefficient calculating unit(152) converts the detected text area into a binary image. The coefficient calculating unit calculates an asymmetric parameter of the binary image. An orientation detecting unit(153) detects the orientation of the image based on the calculated asymmetric parameter. If the orientation of the detected image is different from a default direction, an orientation adjusting unit(154) adjusts orientation about the input image.;COPYRIGHT KIPO 2010
