    • An image reading apparatus includes a reading unit, a control unit, and a pattern region. The reading unit moves a linear reading range, which is provided in a main scanning direction, in a sub-scanning direction that intersects with the main scanning direction while reading an object that faces the reading range, and generates image data on the basis of a read result. The control unit controls the reading unit. The pattern region includes a predetermined pattern that defines a reference position for specifying a reading position that is read by the reading unit. The predetermined pattern has a characteristic portion that specifies a schematic position of the predetermined pattern in the sub-scanning direction. The control unit includes a first image acquisition unit, a pattern searching unit, a second image acquisition unit, a characteristic portion searching unit, a first reprocessing instruction unit, and a second reprocessing instruction unit.
    • 图像读取装置包括读取单元,控制单元和图案区域。 读取单元在读取面向读取范围的对象的同时沿与主扫描方向相交的副扫描方向沿主扫描方向移动线性读取范围,并且基于 读取结果。 控制单元控制读取单元。 图案区域包括限定用于指定由读取单元读取的读取位置的参考位置的预定图案。 预定图案具有指定在副扫描方向上的预定图案的示意位置的特征部分。 控制单元包括第一图像获取单元,图案搜索单元,第二图像获取单元,特征部分搜索单元,第一再处理指令单元和第二再处理指令单元。
