Patent ID: 7590308

Claim:
An image processing apparatus, comprising: a storage unit, in which input image data corresponding to a thumbnail image selected by a user is stored; a reduced image displaying unit, generating reduced image data by thinning the input image data and storing the reduced image data in the storage unit, the reduced image displaying unit displaying reduced image corresponding to the reduced image data on a display; a simulated parameter calculating unit, storing, in the storage unit, a first filter setting set by using the reduced image displayed on the display and calculating a simulated parameter based on the first filter setting; a simulated image displaying unit, generating simulated image data by performing filler processing to the reduced image data in reference to the simulated parameter and displaying a simulated image corresponding to the simulated image data on the display; a parameter calculating unit, calculating a parameter based on the first filter setting; and a filter processing unit, generating output image data by performing filler processing to the input image data in reference to the parameter.
