  The camera control unit 36 includes a shooting area control unit 46 that controls the size of the shooting area of the images shot by the cameras 14a to 14e. An example of “controlling the size of the shooting area” includes enlarging or reducing an image using the zoom function of the cameras 14a to 14e.

  The display control unit 38 includes a display position control unit 47 that controls the display positions of the images captured by the cameras 14a to 14e, and a display area control unit that controls the display area size of the images captured by the cameras 14a to 14e. 48. Here, the “video display position” is a video display position within the display surface of the flat panel display 24. Further, “controlling the size of the display area of the video” means that the size of the display area of the video captured by each of the cameras 14a to 14e is increased or decreased by image processing. This is a different concept from controlling the size of the photographing area by using a zoom function of ˜14e.

Database 32, a video data section 41 of the camera 14a~14e stores data of images captured, and user-related data portion 42 stores information related to user P _R, the algorithm of the arithmetic processing processing computation section 31 performs And a program data section 43 that stores data of a computer program that defines the above. The computer program includes basic software such as application software (written in a programming language such as FLASH or C ++) for displaying video captured by the camera on the flat panel display 24 and an operating system (OS).

  The user position detection unit includes a camera 14c that captures an image of the user's face. The user position detection unit includes a distance measurement unit that obtains the distance between the user and the half mirror 21, and the mirror image display position detection unit 40 specifies the area of the user's head based on the distance. The mirror image display position detection unit 40 detects the position and size of the user's head in the half mirror image based on the video of the user's face.

In addition to this, for example, a sound wave or laser output from one point in the vicinity of the flat panel display 24 is reflected by the head, and the three-dimensional position of the head is detected using the reflected sound wave or laser. The user's head position may be detected using a distance image meter, a laser beam cutting method, or the like. Moreover, by recognizing the face image to a stereoscopic by two cameras installed in some distance position, it is possible to detect the three-dimensional position of the head of the user P _R. For example, the user P combination of disposed in front of the _R camera 14c and the camera 14d which are disposed on the left side, or the head by a combination of a camera 14e arranged in the camera 14c and the right side, which is disposed on the front of the user P _R What is necessary is just to recognize a position. Further, by converting the coordinates from the three-dimensional position of the head, the position where the head of the half mirror image is projected on the flat panel display 24 can be specified. Based on the position where the head of the half mirror images identified projected, the display position control unit 47 does not overlap the image of at least the user's head and the camera 14a~14d is taken in the half-mirror image of the user P _R As described above, the display positions of the images taken by the cameras 14a to 14d are controlled.

Furthermore, the user position detection unit 37 detects the position and distance of the head of the user P _R for the half mirror 21, the field determination unit 44 from the detected position and distance of the user P _R on the display surface of the flat panel display 24 Estimate the field of view. Then, the display position control unit 47 based on the field of view of the user P _R viewing determination unit 44 is estimated, the camera 14a~14d in the same field of view of the user P _R See mirror image of the head of the user P _R Display the shot video. An example of the same visual field range A is shown in FIG.

Action detecting section 45 may detect user behavior P _R by voice input or a button input using a voice recognition function of the user interface unit 39, be detected user behavior P _R at its discretion I do not care.

  Next, an example of the operation of the CPU 31 in FIG. 4 will be described with reference to FIG.

(A) First, in step S01, the camera 14a~14d camera image of the head of the user _{P R} taken are input. Proceeding to step S03, the mirror image display position detection unit 40 identifies the coordinates of the user's head in the camera video. For example, the central axis of the camera 14c is set to (0, 0), and the coordinates of the middle point of both eyes in the camera image captured by the camera 14c are specified.

(B) the process proceeds to S05 step, the user position detection unit 37, a camera 14d and the camera 14e detect the distance between the head of the user P half mirror 21 from the head of the camera coordinate in the images of the _R and the user P _R taken To do. Alternatively, the distance between the user and the half mirror 21 may be specified using distance measuring means using a laser or ultrasonic wave newly provided on or near the half mirror 21. Alternatively, (b) and (b) may be performed simultaneously using a range image camera (x, y, z) or a stereo camera composed of two or more cameras. When a footprint mark is added to a predetermined floor surface to indicate the standing position for the user, the distance between the user's head and the half mirror 21 is fixed, so step S05 is not necessary.

(C) Proceeding to step S07, the mirror image display position detection unit 40 determines the coordinates of the head in the camera image specified in step S03 based on the distance between the user and the half mirror 21 obtained in step S05. Convert to the display position of the head in the image. That is, the coordinates of the binocular midpoint in the camera image are converted to a position where a line horizontal from the midpoint of both eyes to the ground intersects with the half mirror surface at a right angle. This is because, for example, even if the coordinates of both eyes in the camera image taken by the camera 14c are the same, if the distance between the user and the half mirror 21 is different, the display position of both eyes in the half mirror image changes. On the camera central axis, the display position of both eyes in the half mirror image does not change even if the distance is different, but the change increases as the distance from the camera central axis increases. A conversion coefficient that changes in accordance with the deviation angle from the central axis of the camera 14c and the distance between the user and the camera 14c or the half mirror 21 may be determined in advance, and the data may be stored as a table, for example. Further, the coordinates of all head contours may be converted, but the coordinates of only representative points such as the center of both eyes may be converted. Next, the mirror image display position detecting section 40, based on the distance between the head of the half mirror 21 and the user P _R determined in S05 step, the camera image of the face of the user, the user's head (face part) Specify the area. Here, the area of the head in the half mirror image is ¼ of the area of the user's head (or face), and therefore, at the position of the middle point of both eyes in the half mirror image coordinate-converted in step S07. A half mirror image can be seen in an area of 1/4 of the user's head (or face). By this processing, the mirror image display position detection unit 40 can detect the display position of the half mirror image.

(D) the process proceeds to S09 step, field determination unit 44, field of view of the user P _R on the display surface of the flat panel display 24 from the distance and position of the head of the half mirror 21 and the user P _R detected in S05 step Is estimated. The definition of the visual field range and the estimation of the visual field range are set in advance based on a general human visual field.

(E) Proceeding to step S11, the display position controller 47 causes the flat panel display 24 to display the respective user images captured by the cameras 14a to 14d. At this time, based on the position where the head of the half mirror image specified in step S07 is displayed, the display position control unit 47 obtains at least the user's head in the half mirror image and the video captured by the cameras 14a to 14d. The display positions of the images taken by the cameras 14a to 14d are controlled so as not to overlap. Further, the display position control unit 47 based on the field of view of the user P _R estimated in S09 step, the camera 14a~14d is taken in the same field of view of the user P _R See mirror image of the head of the user P _R The display positions of the images taken by the cameras 14a to 14d are controlled so that the images are displayed.
