Abstract
A method and apparatus used to detect errors in image reading simply and quickly. Information derived from image data (such as the amount of data and a compression ratio) after compression is compared with reference values previously determined in connection with errors in image reading, and the existence of errors in image reading is determined. When the data size is used, it is judged that there is an error in image reading when the data size after compression is smaller than the reference value previously determined. When the compression ratio of the image data is used, it is judged that there is an error of image reading in the case where the compression ratio is larger than the reference value previously determined.
