Claims
- 1. An image processing method for converting original image data into aesthetic image data having a pictorial touch, comprising the steps of:
- appointing an area which is at least a portion of the original image data;

- replacing the original image data in said appointed area with said synthesized painting data obtained.
- 2. The method according to claim 1, wherein the synthesized data are obtained by multiplying each item of pixel data contained in said multi-toned sample painting data by said extracted information.
- 3. The method according to claim 1, further comprising the steps of:
- providing plural types of sample painting data;

- (c) randomly generating painting starting positions based on predetermined sample painting data;
- (d) determining whether said extracted edge portion is present at said generated painting starting positions or at positions in the course of painting processing;
- (e) if an edge portion is found not to be present by the determination of said step (d), executing painting processing for each pixel based on said sample painting data for a thick shape and returning to said step (d) until painting processing regarding the sample painting data for the thick shape ends, and returning to said step (c) at the end of painting processing; and
- (f) if an edge portion is found to be present by the determination of said step (d), executing painting processing based on said sample painting data for a fine shape, and returning to said step (c).
- 5. The method according to claim 4, further comprising the steps of:
- providing a single type of sample painting data for the thick shape;
- sequentially subjecting said single type of sample painting data for a thick shape to rotation processing at minute angular increments and within a range of a predetermined angle at maximum; and
- executing said rotation processing whenever painting
- processing ends with regard to said single type of sample painting data for the thick shape.
- 6. The method according to claim 4, further comprising the steps of:
- providing plural types of fine shape sample painting data having directionality;
- detecting the direction of said extracted edge portion; and
- selecting, in dependence upon the direction of said detected edge portion, corresponding sample painting data from said plural types of fine shape sample painting data having directionality.

- substituting means for replacing the original image data in the area appointed by said area setting means with the synthesized painting data obtained by said arithmetic means.
- 8. The apparatus according to claim 7, wherein said arithmetic means obtains the synthesized painting data by multiplying each item of pixel data contained in the multi-toned sample painting data stored in said second memory means by the information extracted by said information extracting means.
- 9. An image processing apparatus for converting original image data into aesthetic image data having a pictorial touch, comprising:
- first memory means for storing original image data;
- second memory means for storing plural types of sample painting data, each one of the plural types of sample painting data including multi-toned data;
- detecting means for detecting, for every locality, properties of the original image data stored in said first memory means;
- selecting means for selecting corresponding sample painting data from the plural types of sample painting data in dependence upon the properties detected by said detecting means;
- information extraction means for extracting information based on the original image data in an area detected by said detecting means;
- arithmetic means for obtaining synthesized painting data from the information extracted by said information extraction means and sample painting data selected by said selecting means; and
- substitution means for replacing the original image data in the area detected by said detecting means with the synthesized painting data obtained by said arithmetic means.
- 10. An image processing apparatus for converting original image data into aesthetic image data having a pictorial touch, comprising:
- first memory means for storing original image data; second memory means for storing sample painting data for a thick shape and fine shape;
- edge extracting means for extracting an edge portion with regard to the original image data stored in said first memory means;
- position generating means for randomly generating painting starting positions based on the sample painting data;
- decision means for determining whether the edge portion extracted by said edge extracting means is present at the painting starting positions generated by said position generating means;
- selecting means for selecting the sample painting data for the thick shape if an edge portion is found not to be present by the determination performed by said decision means and the sample painting data for the fine shape if an edge portion is found to be present by the determination performed by said decision means;
- information extracting means for extracting information based on the original image data in an area at a position generated by said position generating means;
- arithmetic means for obtaining synthesized painting data from the information extracted by said information extracting means and the sample painting data selected by said selecting means; and
- substituting means for replacing the original image data in the area at the position generated by said position generating means with the synthesized painting data obtained by said arithmetic means.
- 11. The apparatus according to claim 10, wherein said second memory means stores plural types of fine shape sample painting data having directionality, and the apparatus further includes detecting means for detecting the direction of the edge portion extracted by said edge extracting means, wherein said selecting means selects, in dependence upon the direction of the edge portion detected by said detecting means when the edge portion is found to be present by the determination performed by said decision means, corresponding sample painting data from the plural types of fine shape sample painting data having directionality stored in said second memory means.
- 12. An image processing apparatus comprising:
