Abstract: When an image, which is an object of reading and which is recorded on a photographic film, is to be registered at a reading position of a film scanner by an operator, following processes are repeated: results of a CCD sensor picking-up the reading position and periphery thereof are fetched; a moving speed V of the photographic film is computed; if the moving speed V is greater than or equal to a reference value, results of pick-up are displayed on a CRT as a high-speed, monochromatic dynamic image; and if the moving speed is less than the reference value, the results of pick-up are displayed on the CRT as a highly-detailed, color dynamic image. In this way, a dynamic image display mode is automatically switched in accordance with changes in the moving speed v during a registration operation, and registration of the image can be carried out quickly and accurately.
