It is intended to allow whether or not a noise included in a read image is a noise due to an ink ejection failure to be more reliably determined. An image reading device includes an image reading unit that reads an image formation surface of paper by using a reducing optical system and a control unit. The image reading unit includes a plurality of read sensors disposed at positions displaced from each other in a main scanning direction. The plurality of read sensors are disposed to be able to read the image formation surface by using at least a local region of the image formation surface as a common region to be read. The control unit determines, based on a first image obtained by a first read sensor included in the plurality of read sensors and on a second image obtained by a second read sensor included in the plurality of read sensors, an amount of displacement of a noise resulting from a parallax between the first read sensor and the second read sensor and determines, based on the amount of displacement, whether or not the noise is present on the image formation surface.
An image reading device comprising:
An image reading method using an image reading device including an image reading unit that reads an image formation surface of a sheet by using a reducing optical system and includes a plurality of read sensors disposed at positions displaced from each other in a main scanning direction, the plurality of read sensors being disposed to be able to read the image formation surface by using at least a local region of the image formation surface as a common region to be read, the image reading method comprising:
A non-transitory recording medium storing a computer readable program for causing a computer of an image reading device including an image reading unit that reads an image formation surface of a sheet by using a reducing optical system and includes a plurality of read sensors disposed at positions displaced from each other in a main scanning direction, the plurality of read sensors being disposed to be able to read the image formation surface by using at least a local region of the image formation surface as a common region to be read, to execute:
An image formation device that causes each of a plurality of nozzles to eject ink to form an image on a sheet, the image formation device comprising:
