Image reading apparatus and method

Image Number 2 for United States Patent #8130421.

An image reading apparatus for reading a document by causing an image sensor having a plurality of light receiving pixels to scan the document including an encoder configured to output pulses according to rotation of a motor, a generating unit configured to generate a read synchronizing signal for the image sensor based on the pulses, an obtaining unit configured to obtain first shading data corresponding to at least two data accumulation time points from the image sensor, and a storage unit configured to store the first shading data, wherein a function is generated with second shading data corresponding to a read data accumulation time point and is corrected on the basis of the first shading data.
