Abstract

A digital image processor that establishes a boundary level of acceptable hardcopy print quality level based on selected image print size and printing magnification and provides a warning to the user prior to generation of the hardcopy print that alerts the user when the determined print image quality will be unsatisfactory.

Claims

1. Digital image processing apparatus for providing to a user an assessment of hardcopy output image quality comprising:

first input means for providing digital image data representative of an image to be reproduced in hardcopy at a user-selected size;

second input means for providing image quality information relating to a hardcopy output image reproduction device, said image quality information being representative of acceptable and unacceptable levels of hardcopy image quality produced with said hardcopy output image reproduction device for different hardcopy image sizes at different levels of image magnification;

third input means for providing information representative of intended output image parameters, including user-selected image magnification and said user-selected size;

processing means responsive to said first, second and third information for determination of when a hardcopy output image generated from said information would result in an unacceptable level of image quality; and

means responsive to said determination by the processing means for indicating to the user prior to generation of the hardcopy output image that an unacceptable level of hardcopy output image quality will result.

2. A method for processing digital image data and providing to a user an assessment of quality of a hardcopy output image to be generated from the digital data, the method comprising:

inputting, to a digital image processor, parameters pertaining to a digital image to be reproduced as a hardcopy output image by a hardcopy output image reproduction device, said parameters including image magnification;

providing, in said digital image processor, image quality information representative of acceptable and unacceptable levels of hardcopy image quality produced with said hardcopy output image reproduction device for different hardcopy image sizes at different levels of image magnification;

determining, in said digital image processor, from said inputted parameters and said image quality information when an image produced on said device would present an unacceptable level of image quality; and

providing, in response to this determination, to the user prior to generation of the hardcopy output image an indication that an unacceptable level of hardcopy output image quality will result.
