摘要： A method and apparatus of forming an image includes reading an original with a first resolution. An original is read with a second resolution which is different from said first resolution. The image information read with the first resolution and the second resolution is converted into image information of a third resolution for image forming. An image is formed with the third resolution based on the image information converted by the conversion.

摘要： An image forming apparatus applies a shading correction to an image read from a white reference board 18, and determines presence or absence of stripe-like noise in the image read therefrom after applying the shading correction. The apparatus exposes an area at which there is no noise in the white reference board 18 to create a white reference value for a shading correction for reading a document after that time.

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.
