Abstract

A computer obtains a change amount of an image of a manuscript. If the change amount of the image of the manuscript is equal to or larger than a predetermined threshold, the computer determines that the image has movement, such as in a case where the manuscript is replaced, and switches the resolution of the image, which is possible to shorten the processing time, to low resolution. In a case where the manuscript is placed on a base, if the change amount of the image of the manuscript is less than the predetermined threshold, and the computer determines that the image does not have movement, the computer switches the resolution of the image to high resolution.
