Patent ID: 8115963

Claim:
An image processing apparatus comprising: an output unit that outputs gradation-processed image data that has been subjected to a gradation process based on preset image quality mode; a receiving unit that receives a display request for displaying a preview image of the gradation-processed image data to be output from the output unit, and a preview magnification indicative of a display magnification of the preview image; an image processing unit that performs a first magnification-altering process on the gradation-processed image data output from the output unit thereby obtaining magnification-altered image data and performs on the magnification-altered image data the gradation process based on the image quality mode if the preview magnification is lower than a present magnification and the gradation process based on the image quality mode is such that the gradation-processed image data does not express halftone, as well as if the preview magnification is higher than the present magnification thereby obtaining processed image data; and a display unit that creates and displays the preview image based on the processed image data.
