Abstract
There is provided an image processing method for performing magnification processing at a specified magnifying power. The method divides the magnification processing at the specified magnifying power into a first magnification processing step and a second magnification processing step and performs the first and second magnification processing steps. A start position of the first magnification processing step and a start position of the second magnification processing step are dislocated relatively to each other so that phases of pixel positions in the first and second magnification processing steps are reversed to each other. There is also provided an image processing apparatus for implementing the method. Artifacts that are generated in image magnification (enlargement and reduction) processing can be suppressed.
Claims18
An image processing method for performing magnification processing at a specified magnifying power, comprising the steps of:
- dividing said magnification processing at the specified magnifying power into a first magnification processing step and a second magnification processing step;
- and
- performing said first magnification processing step and said second magnification processing step,
- wherein a start position of said first magnification processing step and a start position of said second magnification processing step are dislocated relatively to each other so that phases of pixel positions in said first and second magnification processing steps are reversed to each other.
An image processing apparatus for performing magnification processing at a specified magnifying power, comprising:
- a device for performing a first magnification processing step;
- a device for performing a second magnification processing step;
- and
- a device for dislocating a start position of said first magnification processing step and a start position of said second magnification processing step relatively to each other so that phases of pixel positions in said first and second magnification processing steps are reversed to each other.
