Patent ID: 7356202

Claim:
An image processing apparatus, comprising: a storage device which stores input image data in a first area; a refuging device which stores, in a second area of the storage device, sample image data produced from the input image data that has been stored in the first area; a parameter registration device which stores, in a third area of the storage device, parameters inputted by a user that are to be referred to for each kind of process that is performed for filtering the sample image data in the second area; a first calculating device which calculates display parameters by referring to the parameters stored in the third area in accordance with a display size of a display; a pseudo display which outputs, to the display, pseudo image data obtained by performing a number of different processes for filtering the sample image data stored in the second area by using the display parameters calculated by the first calculating device in an order which is predetermined based on a kind of the different processes, when the user inputs at least one of the parameters; a second calculating device which calculates print parameters by referring to the parameters stored in the third area in accordance with a print output size; and a filtering device which performs a number of different processes for filtering the input image data in the first area by using the print parameters calculated by the second calculating device in the order to obtain image data for output, wherein when the user inputs at least one of the parameters, the parameter registration device replaces previous parameters with at least one changed parameter according to the user input, and the pseudo display device updates the pseudo image data by performing, in the order, a number of different processes for filtering the same image data by using the display parameters calculated by the first calculating device by referring to all of the parameters including the changed parameter and outputs the updated pseudo image data to the display.
