An imaging device (10) has a card reader (13), a reflective scanner (14) and a film scanner (15). The scanners has a pre-scanning mode of a low resolution and a fine scanning mode of a higher resolution. A preview image is displayed on the basis of image data taken from an original image through the scanner in the pre-scanning mode, and a cropping area of the original is designated on the preview image. An input resolution setting section (26) automatically sets the higher resolution for the fine scanning in accordance with the original size of the cropping area, a print size of the cropping area, and an output resolution of a printer (16). Based on image data taken at the higher resolution from the cropping area of the original image, the printer prints out an image.
