Abstract
An image processing method includes the steps of contracting an original image consisting of plural pixel data to produce a contracted image; comparing a pixel data of the original image with a corresponding pixel data of the contracted image; registering the pixel data of the original image as a registered data if it is judged in the comparing step that a color difference between the pixel data of the original image and the corresponding pixel data of the contracted image is larger than a predetermined value; and substituting the pixel data of the original image with one of a plurality of registered data only if the color difference is not larger than the predetermined value. An apparatus for performing this method is also disclosed.
Claims37
An image processing apparatus, comprising:
- means for contracting a first image having a plurality of pixels to produce at least one contracted image having fewer pixels than the first image;
- means for comparing each of the pixels of the first image to a corresponding pixel in the contracted image;
- means for registering the pixel data of the first image as a registered data only if said comparing means judges that a color difference between the pixel data of the first image and the corresponding pixel data of the contracted image is larger than a predetermined value;
- and
- means for substituting a pixel data of the first image with one of a plurality of registered data only if said comparing means judges that a color difference between the pixel data of the first image and the corresponding pixel data of the contracted image is not larger than the predetermined value.
An image processing apparatus, comprising:
- means for contracting a first image having a plurality of pixels to produce a contracted image having fewer pixels than the first image;
- means for comparing pixels in the first image to corresponding pixels in the contracted image;
- means for determining if a difference in value between a selected pixel in the first image and a corresponding pixel in the contracted image exceeds a predetermined value;
- and
- means for replacing a value of the selected pixel with a value of the respective corresponding pixel in the contracted image if the difference between the selected pixel and the respective corresponding pixel does not exceed the predetermined value.

An image processing apparatus, comprising:
- a contractor for contracting a first image having a plurality of pixels to produce at least one contracted image having fewer pixels than the first image;
- a comparator for comparing each of the pixels of the first image to a corresponding pixel in the contracted image;
- a register for registering the pixel data of the first image as a registered data only if said comparator judges that a color difference between the pixel data of the first image and the corresponding pixel data of the contracted image is larger than a predetermined value;
- and
- a substituter for substituting a pixel data of the first image with one of a plurality of registered data only if said comparator judges that a color difference between the pixel data of the first image and the corresponding pixel data of the contracted image is not larger than a predetermined value.
The image processing apparatus, comprising:
- a contractor for contracting a first image having a plurality of pixels to produce a contracted image having fewer pixels than the first image;
- a comparator for comparing pixels in the first image to corresponding pixels in the contracted image;
- a determiner for determining if a difference in value between a selected pixel in the first image and a corresponding pixel in the contracted image exceeds a predetermined value;
- and
- a replacer for replacing a value of the selected pixel with a value of the respective corresponding pixel in the contracted image if the difference between the selected pixel and the respective corresponding pixel does not exceed the predetermined value.
