    • An image reading apparatus includes a reading unit, an extraction unit and a generation unit. The reading unit outputs reference plate reading information. The extraction unit sets a pixel of the reference plate reading information as a notice pixel and repeatedly extracts one of the notice pixel as a target pixel until the number of the target pixels is more than a predetermined value when a ratio of a pixel value of the notice pixel to an initial value is more than a predetermined range. The generation unit generates correction information by substituting a pixel value of the target pixel with a correction value using the initial value when the extraction unit extracts all pixels of the reference plate reading information, and generates correction information by setting the pixel values of all the pixels as the initial value when the extraction unit does not extract all the pixels.
    • 图像读取装置包括读取单元,提取单元和生成单元。 读取单元输出参考板读取信息。 提取单元将参考板读取信息的像素设置为通知像素,并且当目标像素的数量大于预定值时,重复地将通知像素中的一个提取为目标像素,直到目标像素的数量大于预定值 通知像素到初始值大于预定范围。 当提取单元提取参考板读取信息的所有像素时,生成单元通过使用初始值用校正值代替目标像素的像素值来生成校正信息,并且通过设置所有像素的像素值来生成校正信息 作为提取单元未提取所有像素的初始值。
