4. An image processing apparatus according to claim 3, wherein the face image area recognizing section compares color data within the color image with face recognition color data changed by the recognition color changing section, and recognizes an area having color data conforming to any of the changed face recognition color data as a face image area.

5. An image processing apparatus according to claim 1 wherein the area designating section outputs changes in the position and size of the formed frame to the frame forming section, wherein the frame forming section reforms the frame based on these changes.

6. An image processing apparatus according to claim 1 wherein the face image area recognizing section displays the recognized face image area on the display in reverse on a complementary color basis.

7. An image forming apparatus according to claim 1, wherein the function of the area designating section is displayed as an icon on the display.

8. A storage medium containing thereon a computer program for controlling an image processing apparatus having a display section, a recognition color memory changeably storing face recognition color data in advance for recognition of a face image of a human object image in a color image, a recognition designating section for designating implementation of a face image area recognizing operation, and a frame designating section for designating a face image pickup area for a recognized face image,

the computer program performing the functions of:

causing a computer operation to display a color image which includes a human object on a display;

causing a computer operation to compare color data in the image with said face recognition color data changeably stored in advance to automatically recognize a plurality of face image areas based on color data of the color image conforming to any of the face recognition color data, wherein one the plurality of face image areas is a designated face image area;

causing a computer operation to form a frame around the designated face image so that the frame proportionally embraces the designated face image area; and

causing a computer operation to cut out the face image area enclosed within the frame.

9. A storage medium according to claim 8, wherein said computer program further performs the functions of causing a computer to change the face recognition color data stored as face recognition colors in the recognition color memory when the face recognition color data is displayed on the display, and causing the computer to output the changed face recognition color data to the face image area recognizing section.

10. A method for controlling an image processor, comprising:

displaying a color image having a plurality of human objects on a display;

comparing color data of the color image with face recognition color data changeably stored in advance for recognizing a face image area on the display;

automatically recognizing an area in the color image where its color data conforms to the face recognition color as a designated face image area in a face image area recognizing section, the designated face image area being from one of the plurality of human objects;

framing the designated face image area in a frame on the display, wherein the frame size and designated face image area are adjustable on the display so that the frame proportionately embraces the designated face image area; and

cutting out the face image area on the display.

11. The method according to claim 10, further including:

updating the face recognition color data when it is displayed; and

outputting the updated face recognition color data to the face image area recognizing section.

12. An image processor, comprising:

a display for displaying a color image which includes at least a human object;

a face image area recognizing section for comparing color data of the color image with face recognition color data changeably stored in advance on the display, wherein the face image area recognizing section automatically recognizes an area containing color data which conforms to the pre-stored face recognition color data, the recognized area being selected as a face image area; and

a face image area cutting section for cutting out a face image from the selected face image area within a frame on the display so that the frame proportionately embraces the designated face image area prior to cutting out the face image.

13. An image processor according to claim 12, wherein the face image area recognizing section extracts an area having the greatest size from the recognized area as the selected face image area.

14. An image processor according to claim 12, further including a recognition color changing section for updating the face recognition color data when it is displayed, and for outputting the updated face recognition color data to the face image area recognizing section.

15.
