PROBLEM TO BE SOLVED: To provide an image reading apparatus which is provided with a color line sensor and a monochrome line sensor and shortens the time, until the output of the first copy after instructing the start of copying, when reading an original image based on different parameters, and to provide a control method for the apparatus. SOLUTION: Prior to reading the original image, whether a monochrome read mode of reading the original image by the monochrome line sensor or a color read mode of reading the original image by the color line sensor is predicted, and preparation of reading an original image based on parameters, corresponding to the predicted mode is completed, before the start of reading the original image. In such a configuration, the time loss arising from switching of a color mode associated with user color setting at the start of a job is reduced, and FCOT is improved. COPYRIGHT: (C)2010,JPO&INPIT
