Abstract: A method and device for displaying history information are provided in which, when a plurality of image processings are carried out repeatedly, a plurality of images which have been subjected to image processing automatically remain as a history record, and this history record is displayed in image states which can be visually discerned, such that a desired image can be intuitively determined. When an image which has been subjected to image processing on an image-to-be-processed display screen is closed and subjected to another image processing, or is subjected to an additional image processing, images displayed on the image-to-be-processed display screen up to before a next image processing is carried out are displayed as icons in a past image icon display portion beneath the image-to-be-processed display screen. Thus, a function can be provided for listing up a history of image processings or providing a gallery stocked with image states which are results of intermediate processings.
