Title of the invention: System for taking peripheral views of a subject FIELD OF THE INVENTION

[0001] The present invention relates to a system for taking peripheral pictures of a subject in combination with a mirror incorporating a screen for alternative vision between the image reflected by the mirror and the image of the shot. STATE OF THE ART

[0002] An imaging system is already known for allowing a subject to see themselves in front view and in top view. This system consists of a location for the subject with an image module comprising a semi-transparent mirror and a display screen placed behind the mirror facing the subject standing at the location. A camera looking at the back of the subject standing at the location and taking their back image and a processor managing the operation of the image module and the camera to display on the mirror the front image of the subject alternating with the back image taken by the camera.

[0003] PURPOSE OF THE INVENTION

[0004] The aim of the present invention is to develop an imaging system allowing peripheral photography of the subject and integration of the image into a video sequence.

[0005] DISCLOSURE AND ADVANTAGES OF THE INVENTION

[0006] To this end, the invention relates to a system for taking peripheral views of a subject in combination with a mirror incorporating a screen for alternative vision between the image reflected by the mirror and the images of shots displayed on the screen integrated in the mirror, a system characterized in that it comprises: a location driven in rotation for the subject, a lighting assembly distributed around the location, a mirror incorporating a display screen for presenting the image of the mirror and for displaying the images obtained from the views, a shooting equipment facing the subject for taking peripheral views of the subject in different rotational positions of the location, a background facing the shooting equipment beyond the location of the subject, a management unit comprising an image processing unit and a control unit for receiving the commands and providing images from the processing of the views,these images being capable of being displayed and control signals for shooting and lighting as well as displaying the images and training the location of the subject.

[0007] Thus, the invention makes it possible to take a sequence of images under identical conditions of the subject which is presented at different angles of rotation in front of the camera.

[0008] The lighting is adjusted for this shooting position in which the subject rotates. This ensures better quality and good homogeneity of the images of the subject. Installation and its positioning in relation to the subject are simplified.

[0009] According to another advantageous characteristic, the lighting equipment comprises lighting units distributed around the location, which are adjustable in intensity and color.

[0010] According to another advantageous characteristic, the lighting equipment comprises lighting units distributed around the location, which are adjustable in intensity and color.

[0011] The various means of the invention are adjusted simply in relation to the subject in its rotational position facing the camera; this does not require modifications to the settings as would be necessary for a camera rotating around the subject and which, itself, would be in a fixed position.

[0012] According to another advantageous characteristic, the mirror has a part for presenting the mirror image of the subject and integrating a screen, the part of the mirror being semi-transparent.

[0013] In particular, the mirror has a part for presenting the image of the subject, this part being bordered on at least one side by a part incorporating a screen, this or these mirror part(s) being semi-transparent.

[0020] DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0021] [Fig.l] shows the diagram of a peripheral shooting system 100 in a room for taking pictures of a subject S installed on a location 1 formed by a plate 11 driven in rotation on command to turn the subject facing shooting equipment 4.

[0022] The system 100 comprises a lighting assembly 2 composed of different lighting units 21, 22, 23, 24, around the location 1, for example, in the corners of the room.

[0023] The system 100 is completed by a mirror 3 facing the location 1 of the subject. This mirror 3 integrates a video screen to display the image(s) obtained from the views taken by the equipment 4 in place of or next to the IMo image of the subject on the mirror 3.

[0024] The shooting equipment 4 installed facing the subject S, but not facing the mirror 3 comprises a camera 41 with a support 42 adjustable in height and orientation and a control unit 43 of the support and the camera 4L. The views Vi taken by the camera 41 must be in agreement with the image IMo of the mirror when the subject is in place in front of the mirror 3 before any rotation of the plate 11, that is to say when the plate is in its rest position Po.

[0025] For this, the camera 41 must be adjusted in orientation in accordance with the position of the subject S, for example, standing or sitting at location 1 So that the camera is, preferably, at a height equal to that of the eyes of the subject S who will not be disturbed when displaying the images li obtained from the views Vi taken by the camera 4L

[0026] The adjustments are made by the control unit 41 which receives the commands from the management unit 6 to act on the camera 41 and its support 42.

[0027] A background 5 is facing the shooting equipment 4, beyond the location 1 to take views of the subject (S) on a neutral surface 51 possibly replaced by a decor 52.

[0028] The peripheral image capture system 100 is managed by a management unit 6 comprising an image processing unit 61 receiving the views Vi from the image capture equipment 4 and processing them to generate images li transmitted to the screen integrated into the mirror 3, or recorded to be broadcast on another screen or used for publications and printing.

[0029] The management unit 6 also comprises a control unit 62 which receives the commands Ci from a program or from the subject S or from an operator to activate the various shooting means such as the rotation of the plate 11, the operation of the lighting assembly 2 by activating the lighting units 21.. .24 as a function of the subject S or its rotation position and for the display of the images li obtained from the views Vi.

[0030] The control unit 6 manages the combined operation of the shooting equipment 4 and that of the background 5 which can be a background with a surface 51 provided with a particular decoration 52 intended to be integrated into the image(s) 11. The processing unit of images 62 can also integrate a decoration into the images it receives, the background 5 then being a neutral background.

[0031] The controlled lighting equipment 2 provides fixed, or continuous or variable lighting of the subject S by the intensity of the lighting, the orientation of the beams on the subject and the nature of the light emitted by each of the lighting units 21-24.

[0032] The lighting equipment 2 is represented diagrammatically by the separate lighting units 21-24. It can also be constituted by peripheral lighting activated globally, or locally depending on the rotation position of the subject S, i.e. of the platform 11.

[0033] The operation of the system 100 is ensured by a program for automatic operation of a shooting sequence, or the control by the subject S which activates the rotation of the plate 11, its stopping, its direction of rotation and, if necessary, it intervenes on the shooting by the lighting assembly 2 or the shooting equipment 4 for close-up or overall views Vi of the subject S in the different rotation positions of the plate 11.

[0034] The control by the subject S also allows him to display, after a sequence of shots and return of the subject to position Po, facing the mirror 3, the images li or sets of images on the screen integrated in the mirror 3 by, for example, alternating the processed images li with the image IMo reflected by the mirror 3 or to display only the processed images li.

[0035] In more detail, the location 1 consists of a rotating plate 11 on which the subject S stands; it is rotated on command around the axis ZZ, by a drive unit 12 with an electric motor. The rotating plate 11 is driven according to different operating modes, generally for one revolution, for example:

[0036] - continuously,

[0037] - in step-by-step mode,

[0038] - on one or more fixed positions, for example different angular positions predefined positions considered to be particularly interesting such as:

[0039] * three-quarter front views on one side or the other of the median plane of the subject S,

[0040] * three-quarter rear views on one side or the other of the median plane of the subject S,

[0041] * rear views of the subject S,

[0042] to have characteristic views when it is not useful to have many intermediate views or a continuous scrolling of views.

[0043] [Fig.2] shows diagrammatically different positions and the organization of the shots.

[0044] In principle, a sequence of shots corresponds to a rotation of the plate 11 of 360°, (for example, in the clockwise direction SH) in the reference frame of axes XX and YY around the vertical axis ZZ:

[0045] - axis XX is that of the rest position Po of the plate 11, facing the mirror 3,

[0046] - the YY axis, for example perpendicular to the XX axis, is that of the equipment of shots 4 and opposite, beyond location 1, background 5 which appears on the views,

[0047] - the ZZ axis is the rotation axis of location 1.

[0048] The arrangement of the various components of the installation in the room around location 1 is given as an example.

[0049] For practical reasons, the camera 41 of the shooting equipment 4 is not facing the subject S at the rest position Po of the plate 11 because of the space required for the mirror 3 facing the subject S in this position.

[0050] In general, since the images li obtained from the views Vi are intended to be viewed by the subject S installed on the plate 11 in a standing or sitting position, the height of the subject's eyes fixes the height of the shot so that the images li can be displayed on the screen and viewed like the image IMo returned by the mirror 3.

[0051] For this reason, the mirror 3 must have dimensions allowing the image IMo of the standing subject to be presented and must have an appropriate height, knowing that the surface occupied by the image in the plane of the mirror 3 corresponds to half the total height of the subject in his standing or sitting position; this rule also applies to the width.

[0052] This part 31 of the mirror 3 cannot be occupied by the equipment 4 which must be offset from this position according to the possibilities and advantages linked to these. In the example, the offset is 90° so that the subject S will only be taken in front view after a 90° rotation of the plate 11. This offset has no effect in itself on the sequences of views Vi whose shooting begins with the view V90 which is 90° ahead of the front view VI80 of the subject.

[0053] The angle a of the plate 11 relative to the rest position (Po) is used as an index to locate the views, for example the view V90 is the view of the subject at the rest position Po of the location, the equipment 4 being offset by 90° (axis YY relative to the position Po) of the location 1.

[0054] To simplify the description, it is assumed that the images are taken with an angular resolution of 1° and thus the sequence of images on one rotation will be composed of the views V0-V3600, the index being the rotation angle of the plate.

[0055] The shift between the mirror image IMo of the subject S facing the mirror 3 at the rest position Po and the first view V90 corresponds to the shift ôa=90°. The sequence of views identified with respect to the four cardinal points of the plateau Po, P90, PI80, P270, for the shift ôa, gives the following succession of views: V90-V180-V270-V0-V89 For the views of the cardinal points of the plateau V90-V180-V270-V0-V89 and likewise for the intermediate views.

[0056] The sequence of views Vi is processed by the processing unit 61 for a coherent display of the images li on the screen integrated in the mirror 3:

[0057] - the views Vi are direct views which must be transformed into mirror images Fi by a left-right inversion so that when displayed on the screen of mirror 3, the image of view Vi li has the same orientation as the image IMo of subject S on mirror 3.

[0058] The scale of the image li must also be reduced to the size of the image IMo (½) of the subject S, adapted according to the distance between the shooting equipment 4 and the subject S.

[0059] The order in the sequence is preferably brought into line with the scrolling of the views by correcting the offset ôa so that the scrolling of the views facing the subject S standing on the plate 11 at the rest position Po begins with the view V90, the section of views V0-V89 being placed behind the sequence of views V90-V359. The images li obtained by the processing of the views li will be numbered in the order starting with the image lo of the view 90 which is the front view of the subject S.

[0060] The scrolling of the images li in front of the subject S in the rest position Po can be done in the clockwise direction (SH) or the counter-clockwise direction (SCH) continuously or at preselected angular positions.

[0061] If the resolution of the images li is sufficient, the display on the screen can also benefit from an enlargement option to view details of the images li.

[0062] The different images li which are the peripheral images of the same attitude of the subject S allow him to see or correct the arrangement of the parts of the clothing or in the case of an actor, to correct certain attitudes for his exercise or for images which will be used as documents.

[0063] The different front views or images from three-quarter or other angles make it possible to select the most interesting images, for example, for images intended for display or printing.

[0064] The control of the movement of the platform 11 and the various equipment 2, 3, 4 is done by a remote control connected to the management unit 6 and integrated into the location 11, for example, a remote control that can be held by the subject or a foot control. This control can also be done by an operator or automatically by a program. The transmission of the control signals of the various equipment is preferably done by wifi (registered trademark).

[0065] The lighting equipment 2 consists, for example, of lighting units 21-24 distributed around the location 1 and making it possible to illuminate, in a controlled manner, the intensity, the orientation and the color of the lighting of the subject S to emphasize this or that part of the subject in its instantaneous position facing the shooting equipment 4, to obtain different technical effects or image qualities.

[0066] The shape of the lighting of the subject S can accompany it during its rotation or be variable according to the part of the subject exposed to the shooting equipment 4 or be adapted to the part of the subject presented in front of the equipment 4, in particular if a certain view is zoomed, to present a part of the clothing or clothing accessories of the subject facing the equipment 4.

[0067] According to [Fig.3], the mirror 3 incorporating a video screen can present the image of the mirror alternating with the images li or in combination with them.

[0068] For alternating viewing, the part 31 of the mirror facing the subject S in position Po incorporates a video screen 31a; this part 31 must then be semi-transparent.

[0069] For the combined vision, the part 31 of the mirror directly facing the subject S is limited to the surface necessary for the presentation of the image of the subject by the mirror; the mirror parts 32, 33 laterally bordering this central part 31 integrate a video screen 32a, 33a to display views Vi allowing the direct comparison of the images li and the image IMo of the subject installed at the location 1. This allows the subject to modify the attitude, the arrangement of the clothes or accessories and to make a new sequence of shots for a new comparative study of the results on the images li. For advertising images, the lighting, shooting angles, zooms and other photographic effects will be modified and will allow a selection of the most appropriate views.

[0070] For the shots, the background 5 can remain a neutral surface 51 and a decor 52 can be chosen and then integrated into the views Vi. With a background 5 with decor presented behind the subject, the decor will be integrated directly into the views and will allow adaptations, modifications of the decor and the subject, of these clothes and accessories directly, in the views Vi taken with the decor 52 of the background 5.
