ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to an image processing apparatus for processing image data to be printed by a printing unit.
2. Related Background Art
Generally, in a printing apparatus represented by a laser beam printer or the like, pixel image data according to a resolution of a print mechanism unit is produced in an image memory by an image processing apparatus and is printed by the print mechanism unit.
To hold a pixel image of an image of a predetermined mined size in the image memory, however, a memory area which is specified by the resolution of the printing apparatus is necessary. Therefore, for instance, in the case of outputting the image data to a printing apparatus of a high resolution, there is the drawback that a larger memory area is needed to keep a pixel image of an image of the same size as compared with the case of a printing apparatus of a low resolution. Such drawback is remarkable, particularly, in the case of using a color printing apparatus or the case of executing a gradation recording.
SUMMARY OF THE INVENTION
It is an object of the invention to provide an image processing apparatus which can avoid the above drawbacks.
Another object of the invention is to provide an image processing apparatus which receives code data such as a page description language or the like and can develop the image in a form according to a memory capacity.
Still another object of the invention is to provide an image processing apparatus in which, even if a printing apparatus of a high resolution or a high precision is connected, a high quality image according to the printing apparatus can be reproduced without increasing memory capacity.
The above and other objects, features, and advantages of the present invention will become apparent from the following detailed description with reference to the accompanying drawings.
