Abstract:
An image reading and processing method which is capable of automatically obtaining image data with high resolution along the proper contour of an original. First image reading is carried out on the original at a first resolution to obtain image data. The contour area of an image of the original 7 is detected based on the image data obtained by the image reading. Second image reading is carried out on the original at a second resolution higher than the first resolution, over an area 51 having outer edges thereof shared by the contour area 41, to obtain image data. The contour of the image of the original is detected in the contour area 41, based on the image data obtained by the second image reading. Image data of an image portion inside the detected contour of the image of the original is extracted from the image data obtained by the second reading.
