When sequentially reading a plurality of documents in an image reading apparatus using, for example, an automatic document feeder, the temperature inside the apparatus rises and the refractive index of a lens or the like in an optical system changes, causing focus and magnification errors. To address this, focus and magnification adjustments are made by reading a chart when a document reading operation is not being performed. On the other hand, during a document reading operation, the temperature inside the apparatus, especially, the temperature of the lens, is measured, and the focus and magnification are adjusted based on the measured temperature.
