         5 . A computer-readable memory storing a control program for image processing, the control program comprising:
 instructions for sequentially performing a plurality of image processing processes to image data, each of which changes an appearance of an image corresponding to the image data;   instructions for creating history information that indicates a content of the plurality image processing processes that have been sequentially performed to the image data; and   instructions for displaying (1) an image based on the image data to which the plurality of image processing processes have been performed and (2) image processing information identifying each of the plurality of image processing processes that have been sequentially performed to the image data, in an order that the plurality of image processing processes have been performed to the image data, based on the history information created by the instructions for creating the history information.   
     
     
         6 . A method for image processing, comprising:
 sequentially performing a plurality of image processing processes to image data, each of which changes an appearance of an image corresponding to the image data with a processor;   creating, with the processor, history information that indicates a content of the plurality of image processing processes that have been sequentially performed to the image data; and   displaying, with a display, (1) an image based on the image data to which the plurality of image processing processes have been performed and (2) image processing information identifying each of the plurality of image processing processes that have been sequentially performed to the image data, in an order that the plurality of image processing processes have been performed to the image data, based on the history information created.   
     
     
         7 . A digital camera according to  claim 1 , wherein:
 the history information created by the history creating device is recorded in the recording medium together with the image data.   
     
     
         8 . A digital camera according to  claim 7 , wherein:
 when displaying the image based on the image data recorded in the recording medium, the display unit displays the image processing information based on the history information recorded with the image data.   
     
     
         9 . A digital camera according to  claim 1 , wherein:
 when changing an image to be displayed on the display unit, the image processing information is changed to an image processing information of the image to be displayed.   
     
     
         10 . A digital camera according to  claim 9 , wherein:
 when the image to be displayed is changed to an image based on image data to which no image processing process has been performed by the image processing device, other information is automatically displayed.   
     
     
         11 . A digital camera according to  claim 1 , wherein:
 the image processing information is displayed by an icon or text that is indicative of the image processing information.   
     
     
         12 . A digital camera according to  claim 1 , wherein the plurality of image processing processes are image processing processes selected by the user in an arbitrary order.
