Abstract

A portrait drawing apparatus for storing for each facial part a plurality of attributes thereof (race, sex, age-group, specific shape such as snub or aquiline for nose, etc.) and for allowing the facial part candidates selected as per the designated attributes to be displayed preferentially over the candidates having other attributes so that the operator will determine the appropriate facial parts with ease and combine them into a portrait in the shortest possible time. The apparatus comprises an image display unit, an input unit and a memory unit that stores programs and data, i.e., a facial part attribute table, facial part pattern data and facial part candidate tables. The facial part attribute table includes pattern numbers, facial part patterns, attributes, and address pointers pointing to the facial part pattern data.

Claims

1. A portrait drawing apparatus comprising:

image display means for displaying portrait image data;

storage means for storing pattern data on a plurality of facial parts;

attribute storage means for storing information on attributes corresponding to the pattern data for each of the plurality of facial parts;

input means for inputting attribute information as a condition under which to search for a facial part pattern;

searching means for searching and retrieving appropriate facial part patterns based on attribute information derived from said attribute storage means; and

display control means for sequentially displaying on said image display means facial part patterns of at least one facial part such that the facial part patterns searched and retrieved by said searching means contain the attribute information entered by said input means before displaying the remainder of said facial part patterns of said at least one facial part.

2. The portrait drawing apparatus as claimed in claim 1, further comprising designation means for designating a displayed facial part pattern to be incorporated into a finished portrait image.

3. The portrait drawing apparatus, as claimed in claim 2, wherein said display control means initially displays one at a time facial part patterns identified by said searching means to contain the attribute information input through said input means.

4. The portrait drawing apparatus as claimed in claim 3, wherein the display control means displays facial part patterns that do not contain the attribute information input by said input means when a facial part pattern having the input attribute information has not been designated using said designation means.

5. A portrait drawing apparatus, comprising:

image display means for displaying portrait image data;

storage means for storing base pattern data corresponding to a plurality of facial parts;

base pattern category input means for inputting base pattern category data for indicating a category of a desired portrait image;

base pattern search means for searching the base pattern data for the desired portrait image, said base pattern search means searching the base pattern data included in the category input by the base pattern category input means prior to searching base pattern data excluded from the category; and

display control means for sequentially displaying on said image display means the base pattern data searched by said base pattern search means such that base pattern data included in the category is displayed before base pattern data excluded from the category.

6. The portrait drawing apparatus, as claimed in claim 5, wherein said base pattern search means includes means for continuously searching the base pattern data excluded from the category input by said base pattern category input means after searching all base pattern data included in the category.

7. The portrait drawing apparatus as claimed in claim 5, wherein said base pattern search means searches the base pattern data for the desired portrait image for a single facial part at a time.

8. The portrait drawing apparatus as claimed in claim 7, further comprising designation means for designating a displayed base pattern data to be incorporated into a finished portrait image.

9. The portrait drawing apparatus, as claimed in claim 8, wherein said base pattern category input means further comprises input means for inputting attribute information wherein said display control means initially displays base pattern data identified by said base pattern search means to contain the attribute information input through said input means.

10. The portrait drawing apparatus as claimed in claim 9, wherein the display control means displays facial part patterns that do not contain the attribute information input by said input means when a base pattern data having such attribute information has not been designated using said designation means.

11. A method of creating a portrait on a display apparatus, comprising the steps of:

designating a facial part;

inputting base pattern category data of a desired portrait image;

reviewing a data base containing multiple representations of facial parts for representations having the input base pattern category data of the desired portrait image;

discriminating the representations of the facial parts included in the desired base pattern category data from the remainder of the representations of the facial parts that are not included in the desired base pattern category data;

displaying on the display means at an appropriate location for the facial part on the portrait the representations of the facial parts included in the desired base pattern category one at a time;

designating one of the representations of the facial parts included in the desired base pattern category when one of the representations of the facial parts is appropriate; and

displaying the representations of the facial parts that are not included in the desired base pattern category when none of the representations of the facial parts included in the desired base pattern category are designated.

12. The method as claimed in claim 11, further comprising the steps of:

designating one of the representations of the facial parts that are not included in the desired base pattern category when presented on the display means.

13. The method as claimed in claim 12, further comprising the step of designating another facial part.

14. The method as claimed in claim 13, wherein said steps of inputting desired base pattern category through designating one of the representations of the facial parts that are not included in the desired base pattern category are repeated for each defined facial part in order to complete a portrait.
