Abstract:
An image reading apparatus including a controller configured to perform an update processing for updating shading correction data stored in a memory by a generation processing of generating shading correction data based on an image signal of a reference member and perform a size determination processing for determining a size of a document based on an image signal of the document, wherein, when the document on the document platen is read, the controller performs the generation processing before the document is read, and an image processing portion performs the shading correction using the shading correction data generated before the document is read, and wherein, when the size determination processing is performed, the image processing portion performs the shading correction using the shading correction data stored in the memory, and the update processing is not performed.

Claim (Index 1):
An image reading apparatus, comprising:\n a document platen on which a document to be read is placed; a reference member; a document platen cover, which is openably and closably attached to the document platen; a detector configured to detect an open state and a closed state of the document platen cover; a reader configured to read the document on the document platen while moving a reading position to output an image signal; an illuminator configured to illuminate the reading position; a memory configured to store shading correction data; an image processing portion configured to perform a shading correction on the image signal using the shading correction data; and a controller, which is configured to: perform an update processing in which the controller makes the reader read the reference member, performs a generation processing of generating shading correction data based on the image signal of the reference member output from the reader, and updates the shading correction data stored in the memory using the generated shading correction data, and perform a size determination processing in which the controller moves the reading position to a first position based on that a detection result of the detector is in a first state, then moves the reading position from the first position to a second position while lighting up the illuminator based on that the detection result of the detector is in a second state, and determines a size of the document based on a result of the shading correction performed on the image signal output from the reader while the reading position is being moved from the first position to the second position, wherein, when the document on the document platen is read, the controller performs the generation processing before the document is read, and the image processing portion performs the shading correction using the shading correction data generated before the document is read, and wherein, when the size determination processing is performed, the image processing portion performs the shading correction using the shading correction data stored in the memory, and the update processing is not performed during a period from a time when the detection result falls into the first state to a time when the reading position becomes the second position.
