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 12):
A document size detecting method, the method being performed by an apparatus including a document platen on which a document to be read is placed, a document platen cover, which is openably and closably attached to the document platen, an opening and closing detector configured to detect an open state and a closed state of the document platen cover, and a reader including a light source configured to emit light to the document placed on the document platen and a light receiving portion configured to receive reflection light from the document, the reader being configured to read an image of the document in a main scanning direction according to the reflection light received by the light receiving portion, the method comprising:\n correcting a light intensity of the light emitted by the light source using predetermined shading data when the opening and closing detector detects the closed state of the document platen cover; determining a size of the document from the image of the document read by the reader subjected to a shading correction; and obtaining new shading data and storing the new shading data in a storage portion when the opening and closing detector detects the closed state of the document platen cover after the reader reads the image of the document.
