IMAGE READING DEVICE AND CONTROL METHOD THEREOF

To solve a problem in which, when a medium has unevenness, steps, etc. in the thickness direction, image reading means may become unruly, causing disturbances in a read image.SOLUTION: A control unit of an image reading device is capable of executing image correction control after performing a first reading operation of reading the medium while conveying the medium in a first direction, and the image correction control includes a second reading operation of reading the medium while conveying it in a second direction opposite to the first direction, and synthesis processing of obtaining one page of image data by compositing a first area that is a part of the image data acquired in the first reading operation and a second area that is a part of the image data acquired in the second reading operation.SELECTED DRAWING: Figure 5 【課題】厚み方向で凹凸や段差等が存在する媒体では、画像読取手段が暴れて読み取り画像の乱れが生じる場合がある。【解決手段】画像読取装置の制御部は、媒体を第１方向に搬送しながら読み取る第１読み取り動作を行った後、画像補正制御を実行可能であり、画像補正制御は、媒体を第１方向とは反対の第２方向に搬送しながら読み取る第２読み取り動作と、第１読み取り動作で取得した画像データの一部である第１領域と第２読み取り動作で取得した画像データの一部である第２領域とを合成することで一ページの画像データを取得する合成処理とを含む。【選択図】図５
