Abstract: An image reading apparatus which is capable of appropriately performing show-through reduction processing and foundation color reduction processing in accordance with an operation for changing the color of a background member to another one having different color that is read along with an original. An image reading unit reads an image of a conveyed original. A background member has a white-colored member and a black-colored member and is disposed in such a manner that it opposed to the image reading unit. A moving unit moves the background member. A CPU determines a degree of image processing to be applied to read image data depending on the color of an opposing portion of the background member, which is opposed to the image reading unit that is reading an original.

Abstract: A first set-value calculating unit calculates a first set value of a black-level feedback based on a reflection amount that increases a speed of tracking to a black-level target value in a black-level feedback control. A second set-value calculating unit calculates a second set value of a black-level feedback based on a reflection amount that slows down a tracking to a black-level target value as compared to the speed of tracking of the first set-value calculating unit. A selecting unit selects and outputs any one of the first set value and the second set value and outputs selected value as a set value. A controlling unit controls selection of any one of the first set value and the second set value by the selecting unit based on the black differential value and a gain of the image data.

Abstract: An image reading device having an improved shading compensation capability and a method thereof are disclosed. The image reading device includes an automatic document feed unit to deliver documents along a document delivery path. A light source unit including a light source to illuminate a first criterion image at a first position within the image reading device, and to illuminate the documents delivered by the automatic document feed unit at a second position. The image reading device further includes a second criterion image arranged to opposingly face the light source unit when the light source unit is located at the second position. The second criterion image extends along a sufficient length to cover the scanning range of the light illumination by the light source unit along a main scanning direction. An image acquisition unit is provided to acquire criterion shading data, auxiliary shading data and image data by receiving light reflected from the first criterion image, the second criterion image and the documents, respectively. A control unit is able to update the criterion shading data using the auxiliary shading data, and to use the updated criterion shading data to compensate the image data.
