摘要： An image forming apparatus according to an embodiment of the invention reads an original by mechanically moving an axial light source in a subscanning direction perpendicular to the axis. The image forming apparatus includes: a sensor whose resolution in a main scanning direction parallel to the axis of the axial light source is higher than a designated resolution; a controller that controls the driving speed of the axial light source so that the resolution in the subscanning direction is higher than the designated resolution; an original-image-data generating unit that generates original image data with a resolution higher than the designated resolution in response to the output from the sensor; and an image reducing unit that generates reduced pixels fewer than a specified number of pixels in the original image data to generate a reduced image with a resolution equal to the designated resolution.

摘要： An image copier according to the invention comprises a scanner for reading an image and a printer for forming an image on sheet, and the scanner includes a document table for positioning an original document from which an image is to be read; a document holding cover holding the original document on the original document table and having a light-emitting element for detecting the size of an original document which emits light when the size of the original document is detected, a light source for irradiating the original document with light when an image on the original document is read, a light-receiving element for image reading which receives reflected light from the original document, a controller for the light-emitting element for detecting the size of an original document which controls the light-emitting element for detecting the thickness of the original document, a specific region determination unit for identifying a specific region based on the numbers of pixels in a main scanning direction and a sub scanning direction of image data, and a background correction unit for performing a process of correcting the background of an image which has been read. In the image copier according to the invention, see-through copying of the bottom side can be suppressed by performing a background correction process after an image is read without blocking a sensor hole of a sensor for detecting the size of the original document from light.
