Summary: | To generate highly accurate composite image data.SOLUTION: An image reading system comprises: a document platen on which a document is placed; a photographing unit that is arranged at a position opposite to the document placed on the document platen, and photographs the document in a plurality of different ranges to generate a plurality of pieces of image data of the document; a detection unit that detects overlapping ranges of the plurality of different ranges in the document photographed by the photographing unit; a selection unit that selects, from the overlapping ranges, an overlapping range of the plurality of ranges photographed at the shortest photographing distance between the photographing unit and the document; and a generation unit that generates composite image data from the photographed different ranges based on the overlapping range of the plurality of ranges photographed at the shortest photographing distance selected by the selection unit.SELECTED DRAWING: Figure 1
【課題】高精度の合成画像データを生成することができる。【解決手段】原稿を載せる原稿台と、原稿台に載せられた原稿に対向する位置に配置され、原稿を複数の異なる範囲で撮影して原稿の複数の画像データを生成する撮影部と、撮影部で撮影した原稿における複数の異なる範囲の重複範囲を検出する検出部と、重複範囲のうち、撮影部と前記原稿とが最短の撮影距離で撮影された方の重複範囲を選択する選択部と、選択部で選択された最短の撮影距離で撮影された方の重複範囲に基づいて撮影した異なる範囲から合成画像データを生成する生成部と、を備える。【選択図】図1 |
