Description

Title of the invention: System for capturing peripheral images of a subject. FIELD OF THE INVENTION

[0001] The present invention relates to a peripheral shooting system of a subject in combination with a mirror incorporating a screen for an alternative view 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 itself from the front and from above. This system consists of a position for the subject with an imaging module comprising a semi-transparent mirror and a display screen placed behind the mirror facing the subject standing in the position. A camera looking at the back of the subject standing in the position and capturing its rear image, and a processor managing the operation of the imaging module and the camera to display on the mirror the front image of the subject alternately with the rear image captured by the camera.

[0003] PURPOSE OF THE INVENTION

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

[0005] DESCRIPTION AND ADVANTAGES OF THE INVENTION

[0006] To this end, the invention relates to a peripheral image capture system of a subject in combination with a mirror incorporating a screen for an alternative view between the image reflected by the mirror and the images of the shots displayed on the screen integrated into the mirror, a system characterized in that it comprises: a rotating location for the subject, a lighting assembly distributed around the location, a mirror incorporating a display screen to present the image of the mirror and to display the images obtained from the views, a shooting equipment facing the subject to take peripheral views of the subject in different rotation 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 to receive commands and provide images from the processing of the views,These images are capable of being displayed, and control signals for shooting and lighting, as well as image display and subject positioning.

[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 through which the rotating subject passes. This ensures better image quality and uniformity of the subject. Installation and positioning relative to the subject are simplified.

[0009] According to another advantageous feature, the lighting equipment includes lighting units distributed around the location, which are orientable, and whose intensity and color are adjustable.

[0010] According to another advantageous feature, the lighting equipment includes lighting units distributed around the location, orientable, with adjustable intensity and colour.

[0011] The various means of the invention are simply adjusted with respect to the subject in its rotational position facing the camera; this does not require any adjustments 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 feature, the mirror has a part for presenting the mirror image of the subject and incorporating a screen, the part of the mirror being semi-transparent.

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

[0014] According to another feature, the management module includes an interface, an image processing unit and a control unit, with signal transmission taking place via wifi (trademark).

[0015] Finally, the background includes a neutral surface capable of receiving a decoration, which allows the sequence of images of the subject to be integrated into an environment. Brief description of the drawings

[0020] DESCRIPTION OF EMBODIMENT METHODS OF THE INVENTION

[0021] Fig. 1 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 of a platform 11 driven in rotation on command to turn the subject facing a shooting equipment 4.

[0022] The system 100 includes a lighting set 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 position 1 of the subject. This mirror 3 incorporates 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 for 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 platform 11, i.e. when the platform is in its rest position Po.

[0025] For this purpose, the camera 41 must be adjusted in orientation to correspond with the position of the subject S, for example, standing or sitting at location 1. Preferably, the camera should be at a height equal to that of the subject S's eyes, so that the display of the images li obtained from the views Vi taken by the camera 4L will not be disturbed.

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

[0027] A background 5 is opposite the camera equipment 4, beyond location 1 to produce views of the subject (S) on a neutral surface 51 possibly replaced by a set 52.

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

[0029] The management unit 6 also includes a control unit 62 which receives commands Ci from a program or from the subject S or from an operator to activate the various means of shooting such as the rotation of the platform 11, the operation of the lighting assembly 2 by activating the lighting units 21.. .24 according to 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 equipped with a special decoration 52 intended to be integrated into the image(s) 1. The processing unit d’images 62 can also integrate a background into the images it receives, background 5 then being a neutral background.

[0031] The controlled lighting equipment 2 ensures fixed, 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 schematically represented by the separate lighting units 21-24. It can also consist of 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 by the subject S which activates the rotation of the platform 11, its stop, its direction of rotation and, where appropriate, 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 platform 11.

[0034] The control by the subject S also allows it 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 into 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 platform 11 on which the subject S stands; it is driven in rotation on command around the axis ZZ by a drive unit 12 with an electric motor. The rotating platform 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 particularly interesting, such as:

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

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

[0041] * rear views of 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 schematically illustrates different positions and the organization of the shots.

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

[0045] - the 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 shot 4 and, opposite it, beyond location 1, background 5 which appears in the shots,

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

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

[0049] For practical reasons, the camera 41 of the shooting equipment 4 is not facing the subject S in the rest position Po of the platform 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 platform 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 as the image IMO returned by the mirror 3.

[0051] For this reason, the mirror 3 must have dimensions enabling it to present the image IMO of the standing subject and have an appropriate height knowing that the area occupied by the image in the plane of the mirror 3 corresponds to half the total height of the subject in its 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 associated with them. In the example, the offset is 90° so that the subject S will only be photographed from the front view after a 90° rotation of the platform 11. This offset does not in itself have any effect on the sequences of views Vi, the shooting of which begins with the view V90, which is 90° ahead of the front view VI80 of the subject.

[0053] The angle a of the platform 11 relative to the rest position (Po) is used as an index to locate the views, for example view V90 is the view of the subject at the rest position Po of the location, the equipment 4 being offset by 90° (YY axis relative to the position Po) from 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 revolution will be composed of views V0-V3600, the index being the angle of rotation of the platform.

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

[0057] - the views Vi are direct views that 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 aligned 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 platform 11 in the rest position Po begins with view V90, the section of views V0-V89 being placed behind the sequence of views V90-V359. The images li obtained by processing the views li will be numbered in the order beginning with the image lo of 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 rest position Po can be done in the clockwise direction (SH) or the counter-clockwise direction (SCH) continuously or on preselected angular positions.

[0061] If the resolution of the images li is sufficient, the display on the screen may also benefit from a magnification 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 garment 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 allow the selection of the most interesting images, for example, for images intended for display or printing.

[0064] The movement of platform 11 and the various devices 2, 3, 4 is controlled by a remote control connected to the control unit 6 and integrated into location 11; for example, a remote control that the subject can hold or a foot-operated control. This control can also be performed by an operator or automatically by a program. The transmission of control signals from the various devices is preferably done via Wi-Fi (registered trademark).

[0065] The lighting equipment 2 consists, for example, of lighting units 21-24 distributed around the location 1 and allowing the intensity, direction and color of the lighting of the subject S to be controlled in order to highlight one or another part of the subject in its instantaneous position facing the shooting equipment 4, in order 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 in, 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 alternately with the images li or in combination with them.

[0068] For alternate 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 combined vision, the portion 31 of the mirror directly facing the subject S is limited to the surface area necessary for the mirror to display the image of the subject; the mirror portions 32, 33 bordering this central portion 31 incorporate a video screen 32a, 33a to display views Vi, allowing direct comparison of the images li and the image IMO of the subject positioned at location 1. This allows the subject to change their posture, the arrangement of their clothing or accessories, and to take a new sequence of shots for a further comparative study of the results on the images li. For advertising images, the lighting, shooting angles, zooms, and other photographic effects will be modified, allowing for the selection of the most appropriate views.

[0070] For filming, the background 5 can remain a neutral surface 51 and a set 52 can be chosen and then integrated into the views Vi. With a background 5 with a set presented behind the subject, the set will be integrated directly into the views and will allow for adaptations and modifications of the set and the subject, including their clothing and accessories, directly in the views Vi taken with the set 52 of the background 5.
