A number of copies of the image file to print may be automatically determined based on the face number information. A plurality of image files may also be arranged according to their respective number of detected faces. ## Claims ### Claim 1 A digital image processing method comprising: detecting faces from an input image; obtaining face number information indicating a number of faces detected; and generating an image file including the input image and the face number information. ### Claim 2 (depends on 1) The method of claim 1, further comprising storing the image file on a storage medium. ### Claim 3 (depends on 1) The method of claim 1, wherein generating the image file comprises recording the face number information in a header section of the image file. ### Claim 4 (depends on 1) The method of claim 1, wherein detecting faces from the input image comprises detecting faces from a live-view image. ### Claim 5 (depends on 1) The method of claim 1, wherein detecting faces from the input image comprises detecting faces from a captured image. ### Claim 6 (depends on 1) The method of claim 1, further comprising receiving a signal representing a request to print the image file, determining a number of copies of the image file to print according to the number of faces indicated by the face number information, and controlling printing of the image file such that the determined number of copies of the image file are printed. ### Claim 7 (depends on 1) The method of claim 1, further comprising arranging a plurality of image files according to their respective face number information. ### Claim 8 A digital image processing apparatus for processing a digital image, the apparatus comprising: a face detection unit configured to detect faces from an input image; a face number information obtaining unit communicatively coupled with the face detection unit and configured to obtain face number information indicating a number of faces detected; and an image file generation unit communicatively coupled with the face number information obtaining unit and configured to generate an image file including the input image and the face number information. ### Claim 9 (depends on 8) The apparatus of claim 8, wherein the image file generation unit is further configured to record the face number information in a header section of the image file. ### Claim 10 (depends on 8) The apparatus of claim 8, wherein the face detection unit is further configured to detect faces from a live-view image. ### Claim 11 (depends on 8) The apparatus of claim 8, wherein the face detection unit is further configured to detect faces from a captured image. ### Claim 12 (depends on 8) The apparatus of claim 8, further comprising a printing controller configured to receive a signal representing a request to print the image file and in response thereto, determine a number of copies of the image file to print according to the number of faces indicated in the face number information. ### Claim 13 (depends on 12) The apparatus of claim 12, wherein the printing controller is further configured to control the printing of the image file such that the determined number of copies of the image file are printed. ### Claim 14 (depends on 8) The apparatus of claim 8, further comprising an image file storage unit communicatively coupled with the image file generation unit and configured to store a plurality of image files, each of the plurality of image files including the respective face number information. ### Claim 15 (depends on 14) The apparatus of claim 14, further comprising a digital content management unit communicatively coupled with the image file storage unit, the digital content management unit configured to arrange the plurality of image files according to the respective face number information. ### Claim 16 A computer-readable storage medium having stored thereon a program, the program being executable by a processor and comprising: a code section for detecting faces from an input image; a code section for obtaining face number information indicating a number of faces detected; and a code section for generating an image file including the input image and the face number information. ### Claim 17 (depends on 16) The computer-readable storage medium of claim 16, wherein the code section for generating the image file comprises recording the face number information in a header section of the image file. ### Claim 18 (depends on 16) The computer-readable storage medium of claim 16, wherein the program further comprises a code section for determining a number of copies of the image file to print according to the number of faces indicated by the face number information, in response to a signal representing a request to print the image file. ### Claim 19 (depends on 16) The computer-readable storage medium of claim 16, wherein the method further comprises a code section for arranging a plurality of image files according to their respective face number information. ### Claim 20 A method of controlling an electronic device, the method comprising: receiving a signal representing a request to print an image file; determining whether the image file includes face number information indicating a number of faces included in an image; when the image file includes the face number information, determining a number of copies of the image file to print according to the number of faces indicated in the face number information; when the image file does not include the face number information, determining a number of copies of the image file to print to be a predetermined value; and controlling printing of the image file such that the determined number of copies of the image file are printed. ### Claim 21 A method of controlling an electronic device, the method comprising: receiving a signal representing a request to arrange a plurality of image files according to their respective face number information; determining whether each of the plurality of image files includes face number information indicating a number of faces included in an image; and arranging the plurality of image files including the face number information according to their respective face number information. ### Claim 22 (depends on 21) The method of claim 21, wherein arranging the plurality of image files comprises changing at least one of filenames or logical file locations of the plurality of image files on a storage medium.
