PURPOSE: To provide an image reader, in which the read processing time is shortened at the time of reading a picture of high definition. CONSTITUTION: In the image reader having a plurality of read definitions, monitor processing of the state of a read object is performed at first definition level, and image reading is performed with a second definition of higher definition than the first definition, on the basis of the monitor processing result. A function for discriminating static state of an image with low definition is added to automatically perform image switching to a high definition and the start of read processing.
