Are supplied to a photographed image processor 12 comprising a microcomputer or the like for performing various processes.

  The photographed image data input unit 11 and the photographed image processor 12 are controlled by a central controller (CPU) 13. The captured image processor 12 supplies a display signal to the display device 2 in accordance with an instruction from the CPU 13, and the captured image processor 12 supplies captured image data to be printed to the printer main body 1 in accordance with an instruction from the CPU 13.

  The printer main body 1 prints out in accordance with an instruction from the CPU 13 and the display device 2 displays a screen in accordance with an instruction from the CPU 13.

  In this example, the color photographic image data supplied to the photographic image data input unit 11 is supplied to a human face detection device 14 for human detection. As shown in FIG. 3, for example, the human face detection device 14 includes a skin color region extraction unit 200 and a subject detection unit 300 (see, for example, Japanese Patent Application No. 2002-255865).

  As shown in FIG. 4, the skin color region extraction unit 200 is a color conversion unit that converts each pixel value of color photographed image data input from the photographed image data input unit 11 into coordinate values in a color space. A system conversion unit 212, a histogram generation unit 213 that generates a histogram representing the frequency of appearance of coordinate values converted in this color space, and a maximum point of the frequency of appearance in this histogram and its neighboring pixels are extracted as initial clusters. An initial cluster extraction unit 214 and an initial region extraction unit 215 that extracts a closed region including the initial cluster from the initial cluster extracted by the initial cluster extraction unit 214 and the color captured image data sent from the captured image data input unit 11. When multiple initial clusters are extracted in this initial area, the initial cluster is integrated as one cluster. A star integration unit 216, a region dividing unit 217 that divides the initial region into a plurality of regions according to the distribution state of the pixels in the initial region, and a region that includes pixels belonging to a cluster corresponding to the color of human skin The extracted skin color region is supplied to the subject detection unit 300.

  As shown in FIG. 3, the subject detection unit 300 receives the color photographic image data and the skin color region from the photographic image data input unit 11 and the skin color region extraction unit 200, respectively, and detects the position of the top of the person's head. Top detection unit 313 receives color photographed image data and skin color area, and mouth detection unit 314 detects the position of a person's mouth, and color photographed image data, skin color area, top of head and mouth data are input. The eye detection unit 315 for detecting the position of the eyes of the person, the eye and mouth data are inputted, the jaw detection unit 316 for detecting the position of the person's chin, the color photographed image data, and the data of the mouth and eyes A centerline detection unit 317 that detects the centerline of the face of the person input, data of the centerline of the top, eyes, mouth, and face are input, and a region correction unit 318 that corrects the face region, and color imaging image data Skin color area, the correction data from the data and the area correction unit 318 of the eye and mouth are inputted, and a determination unit 319 Metropolitan extracted skin color area is whether the face of a person.

  In addition to the above-described human face detection device 14 for human detection, there is an apparatus that determines the detection of a face part from face shape recognition. At present, this method has higher detection accuracy of face recognition. If it is registered in advance as a person's face, the detection accuracy of face recognition is remarkably improved. Any person face detecting device 14 for detecting the person may be used.

  When the human face detection device 14 does not recognize a face, it is determined that the image is a landscape image.

  In this example, the face recognition signal obtained by the person face detection device 14 is supplied to the person counting device 15 that counts the number of people.

  In this case, the face recognition signal is not output when the face detection device 14 of this person does not recognize the face, and the face recognition signal is supplied to the person counting device 15 only when the face is recognized.

  The number counting device 15 counts how many people are in the photographed image data, and notifies the CPU 13 of the count value and the photographed image processor 12.

  In this example, the display order when displaying a list of photographed image data stored in the memory card 3 and the number of printouts at the time of printout are automatically determined based on the count value of the number of persons as will be described later.

  In this example, when printing out a memory card 3 in which photographed image data photographed by a digital camera or the like is stored, the memory card 3 is inserted into the memory card slot 3a of the printer main body 1 as shown in FIG.

  At this time, when the power is turned on by operating the power button 4a, a list of photographed images stored in the memory card 3 is displayed on the display screen 2a of the display device 2 as shown in FIG.

  In this example, the display order of the list display on the display screen 2a of the display device 2 can be selected. That is, when the menu button 4c is operated by the operation unit 4, the cursor 2b is operated by the cursor movement button 4b on the menu screen (not shown), and "select image display order" is selected, the display screen 2a is shown in FIG. In this example, four types of selection are made possible.

  In this example, when “ascending order” is selected with the cursor 2b on the display screen 2a, a list of photographed images of photographed image data in accordance with the photographing order is displayed on the display screen 2a.

  In addition, when “descending order” is selected by the cursor 2b on the display screen 2a shown in FIG. 5A, a list display is arranged in order from the newest one at the time of photographing, contrary to ascending order.

  When “order by number of people” is selected by the cursor 2b on the display screen 2a shown in FIG. 5A, the list display is arranged in the order of the number of people counted by the number of people counting device 15 as shown in FIG. 5B. In this case, when the number of people is the same, for example, the shooting order is set, the person shooting image in which the person is shot is first, and then the landscape shooting image is set, and the landscape shooting image is set, for example, in shooting order.

  In addition, when “order of few people” is selected with the cursor 2b on the display screen 2a shown in FIG. 5A, a list display rearranged in ascending order of the number of people counted by the people counting device 15 as shown in FIG. 5C. It becomes. In this case, when the number of people is the same, the shooting order is set, for example, the person shooting image in which the person is shot is first, and then the landscape shooting image is set, and the landscape shooting image is set, for example, in shooting order.

  In this example, the printout mode can be selected. That is, when the menu button 4c is operated on the operation unit 4 and the cursor 2b is operated on the menu screen (not shown) and the cursor moving button 4b is operated to select "printout mode selection", the display screen 2a is displayed in FIG. In this example, two types of selection, “all print” and “selected print”, can be performed.

  In this example, when “Select Print” is selected with the cursor 2b on the display screen 2a of FIG. 6 and the OK button 4d is operated, the captured image data stored in the memory card 3 on the display screen 2a is displayed. The captured images are displayed in a list in the order selected above. In the case of “selected print”, the photographed image on the display screen 2a to be printed out is selected with the cursor 2b, the number of printouts is designated, and the print button 4f is operated. At this time, the designated number of picked-up images can be printed out.

  In this example, when the selected photographed image is a person photographed image and the print button 4f is operated without specifying the number of printouts, the number of persons counted by the number counting device 15 is printed out.

  In this case, it is not necessary to specify the number of printouts, which is convenient. In addition, when the captured images of the captured image data stored in the memory card 3 are displayed in a list in order of increasing number of people or in order of decreasing number of people, and when the landscape image is displayed after that, the person image is first. It is convenient to print out a human photographed image such as travel photographed data first.

  Further, in this example, when “all print” is selected with the cursor 2b on the display screen 2a in FIG. 6, the printout is performed according to the printout program as shown in the flowchart of FIG. That is, when “ALL PRINT” is selected and the OK button 4d is operated (step S3), the captured image data has already been supplied from the memory card 3 in step S1, and the memory cards are already selected in the order selected in step S2. A list of the captured images of the captured image data stored in 3 is displayed (step S4).

  Thereafter, when the print button 4f is operated (step S5), the photographed image data to be printed out is automatically selected according to the display order of the list display on the display screen 2a (step S6). Supply to the main body 1.

  At this time, the face of the person is detected by the person face detection device 14 (step S7), and then the presence or absence of the person is determined (step S8). If there is a person in step S8, the number of people counting device 15 counts the number of people. (Step S9) The selected photographed image data is automatically printed out as a person photographed image for the number of persons (number of persons) (Step S10).

  If it is determined in step S8 that there is no person, the selected photographed image data is printed out as a landscape photographed image (step S11). When this “all print” is selected, steps S6 to S11 are performed for the number of photographed images displayed as a list on the display screen 2a.

  In this example, in the case of human photographed image data, the number of photographed image data is automatically printed out, so that it is not necessary to specify the number of printouts, which is convenient.

  Further, according to the present example, when the captured images of the captured image data stored in the memory card 3 are displayed in a list in order of increasing number of people or in order of decreasing number of people, and when the landscape photographed image is thereafter, this “all print” is set. If selected, the person-captured images are printed out for the number of people first, and the user-captured images such as travel images are printed first.

  Of course, the present invention is not limited to the above-described examples, and various other configurations can be adopted without departing from the gist of the present invention.
