  Hereinafter, embodiments of an image display system of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic diagram showing a preferred embodiment of the image display system of the present invention. The image display system 1 in FIG. 1 is used for generating and displaying a display image AP used for advertising of clothes DL exhibited in a show window 10, for example. The image display system 1 combines a photographing unit 2 that photographs a human subject S looking at a show window 10, a face of the subject S photographed by the photographing unit, and clothes displayed on the show window 10 to display a display image AP. And the display device 100 that displays the generated display image AP.

  As shown in FIG. 1, the photographing unit 2 includes a first camera 2A that photographs the subject S looking at the show window 10, and a second camera 2B that photographs the subject S passing in front of the display device 100. ing. Then, the first camera 2A and the second camera 2B output the first image and the second image to the image display device, respectively. The display device 100 displays the display image AP on the glass surface (light transmission surface) 10a of the show window 10 on which the clothes DL are displayed. The display image AP is displayed on the clothes DL and the subject displayed on the show window 10. It is displayed between S.

Next, FIG. 2 is a block diagram showing a preferred embodiment of the image display system of the present invention.
The image display device 50 will be described with reference to FIGS. 1 and 2. The configuration of the image display device 50 as shown in FIG. 2 is realized by executing a display image generation program read into an auxiliary storage device such as a hard disk device on a computer (for example, a personal computer). The display image generation program is stored in an information storage medium such as a CD-ROM or distributed via a network such as the Internet and installed in a computer.

  The image display device 50 in FIG. 2 uses the face extraction unit 3 for extracting the face information of the subject included in the image obtained by the photographing by the photographing unit 2 and the face information FD extracted by the face extraction unit 3. The subject specifying means 5 for specifying the subject S that provides the display image AP from among the subjects S included in the subject, the motion detecting means 6 for detecting the movement of the subject S specified by the subject specifying means 5, and the movement of the subject S The material storage means 8b in which a plurality of material images CP of the clothes according to the condition are stored, and the material image CP of the clothes used as a display image from the material storage means 8b based on the movement of the subject S detected by the movement detection means 6. A material image selecting means 8a for selecting the image, an image generating means 7 for generating a display image AP using the material image CP of the clothing selected by the material image selecting means 8a, and an image generating means 7 And a display control unit 9 for displaying the generated display image AP on the display device 100 Ri.

  Here, the face extraction means 3 extracts the face information FD included in the first image P1 acquired by the first camera 2A and stores it in the face information storage means 4. Further, the face extracting means 3 extracts each face information FD when the first image P1 includes a plurality of face information FD, and further, for the plurality of first images P1 acquired at different times. The face information FD is extracted. Accordingly, the face information storage unit 4 stores a plurality of pieces of face information FD extracted by the face extraction unit 3.

  As a method for extracting a face in the face extracting means 3, for example, an approximate position and size of the face in the first image P1 is detected, and an image of an area indicated by the position and size is detected from the first image as face information FD. Or other known techniques can be used.

  The subject specifying means 5 displays the face information from the face information storage means 4 by comparing the face information FD in the second image P2 acquired by the second camera 2B with the face information FD stored in the face information storage means 4. The face information FD used as the image AP is selected. That is, for example, when the image display system 1 is used for a show window 10 as shown in FIG. 1, a plurality of subjects S may be photographed in an image photographed by the second camera 2B, which is used for the display image AP. The face information FD may not be correctly selected. Therefore, subject identification means 5 performs face authentication to improve subject identification accuracy and effectively provide the display image AP to the subject S.

  The motion detection means 6 detects the motion of the subject S from the second image P2 acquired by the second camera 2B, and the detected motion information such as “walking”, “turning”, and “turning around” is detected as the material image selection means 8a. To output. The face extraction means 3 extracts the face information FD of the subject S from the first image P1 obtained by the first camera 2A, and the motion detection means 6 moves the subject S from the second image P2 obtained by the second camera 2B. Since the first camera 2A can be photographed under photographing conditions suitable for face extraction and the second camera 2B can be photographed under photographing conditions suitable for motion detection, the face information FD can be extracted. In addition, motion detection can be performed efficiently and accurately.

  Here, as a motion detection method in the motion detection means 6, for example, images at time t and time t + α in the range of the region of interest having a predetermined size are cut out, and the contour lines of the subjects included in these two images are detected. Then, by detecting the difference between the contour lines, the motion in the in-plane parallel direction, the in-plane rotation direction and / or the radial direction of the image is detected, and the background motion is compensated based on the motion of the image. A method for detecting an object that moves differently or other known methods can be used. In addition, an infrared sensor or the like that detects the motion of the subject S in front of the show window 10 may be disposed, and the motion detection unit 6 may detect the motion of the subject by the second image P2 and the infrared sensor or the like. .

  Based on the movement of the subject S detected by the movement detection unit 6, the material image selection unit 8a selects the material image CP of the clothing that matches the movement from the material storage unit 8b. Here, as shown in FIG. 3, a plurality of clothing material images CP associated with the movement information of the subject S are stored in the material storage unit 8b. Specifically, the movement information “walking” is stored in association with the material image CP1 of the clothing on which the model wearing the product is walking, and the movement information “turning” includes the model wearing the product. The material image CP2 of the rotating clothing is stored in association with each other, and the material information CP3 of the clothing in which the model wearing the product turns is stored in association with the movement information “turn around”.

  Note that the material image CP of the clothes may be model real-life data, or may be an image of a body that moves by CG (computer graphics). Further, the material image CP of the clothes may be an image of a model or the like when the same operation as the subject S is performed, or an image that is a mirror image of the subject S when displayed on the display device 100. It may consist of.

  The image generation means 7 generates the display image AP using the material image CP of the clothing selected by the material image selection means 8a. In particular, the image generation means 7 generates the display image AP by synthesizing the face information FD extracted by the face extraction means 3 and the material image CP of the selected clothing. Thus, since the face information of the subject S can be included in the display image AP, the degree of attention of the display image AP can be increased. Furthermore, since the display image AP provided to the subject S by the image display system 1 is generated by the material images CP of various clothes according to the movement of the subject S and is dynamic, Compared to such a static display image, it is easier to draw attention to the subject S, and when this is used for advertising display, the advertising effect can be improved.

  The display control unit 9 displays the display image AP generated by the image generation unit 7 on the display device 100. Specifically, as shown in FIG. 4, the display device 100 includes, for example, a projector device 100A that projects the display image AP on the glass surface 10a side, and a light-transmissive screen 100B that is installed on the glass surface 10a. is doing. The display control means 9 controls the content and display position of the display image AP displayed on the screen 100B by controlling the operation of the projector device 100A. In particular, the display control unit 9 displays a display image AP having substantially the same size as the subject on the display device 100 at a position where the display device 100 faces the subject S. Thus, by displaying the display image AP in front of the subject S looking at the show window 10, the display image AP is displayed at a place that is unexpected for the subject S looking at the show window 10. Therefore, the degree of attention of the display image AP can be increased.

  Further, when the subject S moves in the X direction, the display control means 9 swings the projector device 100A in accordance with the movement of the subject S as shown in FIG. Then, the display image AP displayed on the screen 100B also moves in accordance with the movement of the subject S. Thereby, for example, the display image moves with the subject next to the subject walking along the show window, so that the unexpectedness of the display image can be increased and the degree of attention of the display image can be improved.

  Here, when the display image AP is a moving image, the display control means 9 has a function of adjusting the reproduction speed based on the speed of motion detected by the motion detection means 6. For example, the display control means 9 reproduces the display image AP according to the slow walking speed of the subject S when the subject S is walking slowly, and matches the fast walking speed of the subject S when the subject S is walking fast. The display image AP is reproduced. As a result, the display image AP of the display device 100 can be moved in a substantially face-to-face state without shifting from the position of the subject S.

  FIG. 6 is a flowchart showing an operation example of the image display system and the image display apparatus of the present invention, and an example of an advertisement image display method will be described with reference to FIGS. First, for example, the first camera 2A takes a picture of a passerby looking at the clothes DL of the show window 10 as the subject S (step ST1). Then, the face information FD of the subject S is extracted from the first image P1 acquired by the first camera 2A in the face extraction means 3 of FIG. 2 and stored in the face information storage means 4 (step ST2).

  On the other hand, the subject S is also photographed by the second camera 2B. Then, the subject specifying means 5 extracts face information FD from the second image P2 acquired by the second camera 2B, and determines whether or not the extracted face information FD is stored in the face information storage means 4. (Step ST3). When the face information FD is not stored in the face information storage unit 4, the other face information FD included in the second image P2 acquired by the second camera 2B is extracted and verified. On the other hand, when the extracted face information FD exists in the face information storage unit 4, the face information FD stored in the face information storage unit 4 is sent to the image generation unit 7.

  Further, the movement of the subject S specified by the subject specifying means 5 is detected from the second image P2 by the motion detecting means 6 (step ST4). Based on the detected movement of the subject S, the material image CP of the clothing corresponding to the movement of the subject S is selected as the display image AP from the material storage unit 8b (step ST5). Thereafter, the image generation means 7 generates a display image AP of the selected clothing material image CP and the extracted face information FD (step ST6), and the display image AP generated by the display control means 9 is a mirror image of the subject S. Is displayed on the display device 100 at such a position.

  Specifically, as shown in FIG. 7, when the subject S is standing still looking at the clothes DL of the show window 10 or walking while looking at the show window 10 (with the face facing the show window 10 side). The face detection and motion detection described above are performed, and the display image AP is displayed in front of the subject S. When moving in the arrow X direction, a display image AP based on the walking material image CP is generated, and the display position changes as the subject S moves. Thereafter, when the subject S stops and raises both hands, for example, a display image AP based on the material image CP with both hands raised is generated and displayed.

  Since it is possible to display a display image AP that is an unexpected image including the face of the subject S in an unexpected place of the glass surface 10a of the show window 10 and that moves unexpectedly in synchronization with the operation of the subject S, A great impact can be given to the subject S. Further, when the surprised subject S stops and turns around, the display image AP also turns around and turns, so that a greater impact can be given.

  When a plurality of clothes DL are displayed in the show window 10 as shown in FIG. 1, the image display system 1 may be provided for each clothes DL, or the plurality of first cameras 2A and the first The creation and display control of the display image AP may be performed in one image display device 50 based on the images obtained from the two cameras 2B. When the creation and display control of the display image AP is performed in one image display device 50, the material image CP of the display image AP may be changed seamlessly when the subject S moves in front of the different clothes DL. . As a result, a more effective display image AP can be produced. At this time, the material storage means 8b stores material images of a plurality of clothes such as clothes of different colors and clothes of different types with respect to the movement of one subject.

  The embodiment of the present invention is not limited to the above embodiment. For example, in FIG. 2, the face information FD is extracted and stored using the first camera 2A, and the subject S is specified and detected using the second camera 2B. It may consist of a camera, and the face information FD may be extracted from the image of the subject S obtained by photographing with this camera and the motion may be detected.

  1 illustrates the case where the display device 100 has a size capable of displaying a life-size display image AP of the subject S, the size that can be accommodated in the show window 10. You may make it use the display apparatus 100 which has. At this time, the photographing means 2 may include two cameras 2A and 2B, or may include one camera as described above.

  1 illustrates the case where the display image AP is displayed on the glass surface 10a of the show window 10, the display device 100 is disposed adjacent to the show window 10 as shown in FIG. It may be. At this time, the first camera 2A takes a picture of the subject S looking at the show window 10, and the display image AP is displayed on the display device 100 when the subject S walks to the display device 100 side. Yes. At this time, the second camera 2B is installed on the display device 100 side, and can detect the movement of the subject S on the display device 100 side. Even in this case, it is possible to display the display image AP that is an unexpected image of the subject S and that moves unexpectedly.

  Further, the image generation means 7 in FIG. 2 generates the display image AP by synthesizing the face information FD and the material image CP of the clothing, but the face information FD and the material image CP of the clothing are synthesized. Instead, the material image CP of the clothing may be used as the display image AP, and the material image CP of the clothing may be displayed in accordance with the position of the face of the subject S on the surface of the display device 100.

  Further, when the extracted face information FD is stored in the face information storage means 4 in the face extraction means 3 of FIG. 2, for example, the face extracted by the age group / sex etc. of the advertisement such as clothes displayed in the show window 10 It may be determined whether to store the information FD. Thereby, for example, it is possible to prevent a problem that the male face information FD is synthesized as the display image AP of the female clothing.
