Title: Image reading device and method for controlling image reading device
Inventor: KUGIMACHI HISATAKA
IPC: G06T1/00
Filed: 2020-10-12
Abstract: To provide an image reading device and a method for controlling the image reading device that can reduce the frequency in which the image reading device cannot appropriately remove a blank page.SOLUTION: An image reading device comprises a reading unit that reads a document. The image reading device further comprises: a dirt detection unit that detects dirt on the reading unit and acquires dirt information; a histogram generation unit that generates a histogram of image data of the document read by the reading unit page by page; a blank determination unit that determines whether the document is a blank page based on the histogram; and a blank removal processing unit that removes the blank page from the document data. The blank determination unit determines a printing area pixel number that is the number of pixels in a printing area located on a side with luminance lower than the luminance value of a ground color of the document in the histogram, the amount of dirt α per page of the document based on the dirt information, and a correction threshold according to the amount of dirt α. When the printing area pixel number is equal to or less than the correction threshold, the blank determination unit determines that the document is a blank page.SELECTED DRAWING: Figure 18
