IPC: H04N1/04
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to precisely detect a document width even if a background color on which a document is mounted is an arbitrary one. SOLUTION: Relating to a picture reader an image of a document is picked up by an image sensor to generate picture data, a document tip position obtained by an effective picture element area of the picture data is scanned in a direction of horizontal-scanning from one end to the other, and a position of both ends of the document is decided based on a position calculated from a picture element value in the picture data as a document end candidate position. The device is provided with a color image sensor 1 for picking up an image of the document and generating color picture data of an RGB and a document width detection means 208 which detects the document width position regarding each RGB color of the color picture data generated by the color image sensor 1 and decides the position at both ends of the document.  A processing for deciding the position at both ends of the document is performed with each color of the RGB and it is made possible to detect the document width without being influenced by a background color of the document.
