Description

Product plan making device

The present invention relates to the field of product plane-taking devices.

A product plan of a product is a photograph used to present said product on catalog, website, and other communication channels. A product plan is also known by the Anglo-Saxon name "packshot" or "pack shot". Such a photograph is usually on a plain white background.

It is generally essential, to spread a positive image of the product and of a brand associated with the product, to have a good quality product plan. To do this, it is traditionally called upon professional photographers to produce the product plans.

Recent developments have revealed product plan making devices. Such devices allow any person to carry out a plan produced without calling upon a professional photographer. Such devices are particularly advantageous since they considerably limit the cost associated with taking a product plan.

However, the quality of the product plans produced using the aforementioned devices is still much lower than that of the product plans produced by professional photographers. In particular, there are still shadows and reflections generated by the immediate environment of the product. Sometimes, even objects such as construction elements remain behind the plan produced. These shadows, reflections and objects can require significant retouching work using image retouching software. Sometimes it is even impossible to remove reflections, shadows and objects with existing image editing software.

The invention aims to overcome the aforementioned drawbacks.

In particular, the purpose of the invention is to provide a product shot-taking device which avoids the appearance of shade, reflection or other object in the background while being as simple as possible to use.

To this end, a product plane-taking device is proposed comprising a wall and a tray intended to support a product.

According to a general characteristic of this device, the plate and at least a first portion of the wall define an enclosure intended to receive the product, the first portion being partially opaque.

Therefore, the first portion delimiting with the tray a partially opaque enclosure allows an ideal diffusion of the light emitted from outside the enclosure, thus generating, in addition to direct lighting, indirect lighting of the product in all Angles.

In one embodiment, the interior surface of the first portion has no projecting angle.

The enclosure delimited by a portion of wall devoid of a projecting angle makes it possible to avoid the appearance of reflection or shadow linked to the environment of the object or to the edges of the device.

Advantageously, the inner surface of the first portion is differentiable and of continuous derivative.

Such a design of the interior surface makes it possible to further limit the appearance of shade or of reflection linked to edges of the enclosure.

In one embodiment, the first portion comprises a planar base comprising a first arc of a circle and a second arc of a circle, the radius of the second arc of a circle being strictly greater than the radius of the first arc of a circle, and preferably equal to the radius of the first arc multiplied by a coefficient between 1.5 and 2.5.

This optimizes the use of the space receiving the product by providing a means of shooting above the point of the first arc most distant from the second arc.

Preferably, the plate forms at least partially a plane and has an external contour offset from the base, a projection parallel to the plane formed by the plate of the offset between the external contour and the base being between 25 mm and 35 mm, and / or a projection perpendicular to the plane formed by the plate of the offset between the outer contour and the base being between 7 mm and 13 mm.

Such an offset makes it possible to limit the appearance of a ridge at the level of the external contour.

Preferably, the outer contour is chamfered and / or rounded.

This further limits the appearance of a ridge at the outer contour.

In one embodiment, the first portion comprises at least one opening chosen from a first opening located in a first area, a second opening located in a second area and a third opening located in a third area, the plane tangent to the interior surface. at the points of the first zone forming an angle with the plane formed by the base between 40 ° and 90 °, the plane tangent to the interior surface at the points of the second zone forming an angle with the plane formed by the base between 20 ° and 30 °, the plane tangent to the interior surface at the points of the third zone forming an angle with the plane formed by the base less than 10 °.

The first opening makes it possible to produce product plans in front view. The second opening makes it possible to produce product plans while diving. The third opening enables product plans to be viewed from above. We can therefore produce a wide variety of product plans using these three openings.

In one embodiment, the wall comprises a rail, the device comprising a fixing means and a projector and / or a shooting means which can be fixed to the rail thanks to the fixing means.

In another embodiment, the plate forms at least partially a plane and comprises a fixed part and a mobile part, the mobile part being able to be driven in rotation relative to the fixed part around an axis of rotation perpendicular to the plane formed by the plateau.

Such a design of the plate makes it possible to easily modify a viewing angle of the product on the product plane.

Preferably, the first portion comprises a plane of symmetry, the device comprising a first actuator for the movement of the movable part relative to the fixed part, the first actuator being located in a first sector forming an angle between 90 ° and 135 ° with the plane of symmetry around a median axis of the first portion.

The actuator is thus installed in a blind spot area of a shooting means, so as to further limit the appearance of reflection or parasitic shadow.

For example, the median axis of rotation is defined as the axis of rotation.

Preferably, the device comprises a second actuator located in a second sector symmetrical to the first sector relative to the plane of symmetry.

This improves the pivot connection and the rotational drive between the fixed part and the mobile part without increasing the risk of the appearance of reflection or parasitic shadow linked to the actuators on the product plane.

In one embodiment, the tray is partially opaque, the wall having a second portion, the first portion and the second portion delimiting a space containing the tray, the second portion being opaque and having a white interior surface, the second portion comprising a attachment means, the device comprising a lighting means which can be fixed by means of attachment.

Such an embodiment allows lighting below the object supported by the tray.

It can also be provided that the plate forms at least partially a plane, the first portion being movable in rotation relative to the second portion around a pivot axis parallel to the plane formed by the plate, the second portion having a projection, the projection being located in a sector forming an angle between 40 ° and 50 ° with the plane formed by the plate around the pivot axis.

Such a projection forms a stop for the rotation of the first portion, which makes it possible to open and leave open the enclosure intended to receive the product.

Other objects, characteristics and advantages of the invention will appear on reading the following description, given solely by way of nonlimiting example, and made with reference to the appended drawings in which:

FIG. 1 is a perspective view of a device according to the invention,

FIG. 2 is a cross-sectional view of the device of FIG. 1 in the open position,

FIG. 3 is a cross-sectional view of the device in FIG. 1 in the closed position,

FIG. 4 is a view in vertical section of a first portion of a wall of the device of FIGS. 1 to 3,

FIG. 5 is a view in longitudinal section of the first portion of FIG. 4, and

FIG. 6 is a top view of a tray and of a second portion of the wall of the device in FIGS. 1 to 3.

Referring to Figures 1 to 3, there is schematically shown a device 2. The device 2 is intended for taking a product plane of a product (not shown). More particularly, the device 2 aims to allow any person to take a product plan of the product without the help of a professional photographer.

The device 2 includes in particular a wall designated by the reference 4. The wall 4 comprises a lower portion 6 and an upper portion 8. A direct orthonormal vector base 10 is attached to the portion 6. The base 10 consists of a vector x, a vector y and a vector z. The vector z is oriented vertically upwards when the device 2 normally rests on a horizontal plane surface.

As can be seen in FIG. 1, the wall 4 comprises a plane of symmetry 11 (shown in FIG. 4) perpendicular to the vector y. Figures 2 and 3 are sectional views taken along the plane of symmetry 11. Figure 4 is a sectional view of the portion 8 along the plane IV-IV (see Figure 3) and Figure 5 is a sectional view of portion 8 according to the VV plan (see Figure 4).

Unless indicated otherwise, the terms "upper" and "lower" will be understood to refer to device 2 when it is normally installed on a flat horizontal surface, that is to say assuming the vector z oriented vertically upwards. Likewise, the expressions “forwards” and “backwards” will be understood as referring to the direction and direction of the vector x, the end of origin of the vector x being situated behind and the end of the vector x being located in front.

The portion 6 comprises a plurality of feet 12. In the present case, the portion 6 comprises four feet 12, three of which are shown in Figure 1 and two are shown in Figures 2 and 3.

The portion 6 has two grooves 14. The grooves 14 are substantially identical and are delimited by two cylindrical bottom portions with circular base coaxial with an axis 15. The axis 15 is parallel to the vector y. The portion 8 comprises two cylindrical protrusions 16. The protrusions 16 are substantially identical, of circular section and coaxial with the axis 15. The protrusions 16 are received in the grooves 14. In this way, a pivot connection is made around the axis 15 between the portions 6 and 8. More specifically, the expression “open position” will denote the position of the portion 8 relatively with respect to the portion 6 as shown in FIG. 2, and by the expression “ closed position ”the position of the portion 8 relatively with respect to the portion 6 as shown in FIG. 3.

As illustrated in FIGS. 2 and 3, the portion 6 has a protrusion 18. The protrusion 18 is practiced in an angular sector 20. As can be seen in FIGS. 2 and 3, the sector 20 extends between a plane 22 containing the axis 15 and forming an angle of 40 ° with the plane perpendicular to the vector z, and a plane 24 containing the axis 15 and forming an angle of 50 ° with the plane perpendicular to the vector z. In this way, the protuberance 18 constitutes a stop for the rotation movement of the portion 8 in its open position.

The portion 6 comprises a pair of protrusions 19. The protrusions 19 are located on one face of the portion 6 opposite the face on which the protrusion 18 is located. The protrusions 19 are symmetrical to each other with respect to the plane of symmetry 11. The protrusions 19 are located in an angular sector around the axis 15 such that, when the portion 8 is in its closed position, it rests on the growths 19.

The portion 6 is made of an opaque material having a lower surface of white color. As can be seen in FIGS. 2 and 3, the portion 6 comprises an attachment means 26. The means 26 supports a lighting means 28, in this case a flash projector.

The device 2 comprises a rail 30. The rail 30 surrounds an upper part of the portion 6 and is integral with the portion 6. In addition, the rail 30 is located outside of the portion 8. As illustrated in FIG. 3 , the rail 30 comprises fixing means 32, 34, 36 and 38. The means 32 and 34 are located in the plane of symmetry of the wall 4. The means 36 and 38 are arranged symmetrically with respect to the other with respect to the plane of symmetry of the wall 4. The means 32 is provided for fixing a camera 29. The means 34, 36 and 38 are provided for fixing a lighting means 28 such as a flash projector. Of course, it is not departing from the scope of the invention by considering only one or two of the means 34, 36 and 38 or by adding additional fixing means.

The portion 8 comprises a base 40 shown in the sectional view of Figure 4. The portion 6 and the rail 30 have been deliberately omitted in Figure 4 for the sake of clarity. The base 40 is planar and delimits the portion 8 below. The base 40 is constituted by successive arcs 42, 44, 46 and 48. The arcs 42, 44, 46 and 48 are delimited in FIG. 4 by dotted lines 50. The dimensions of the arcs 42 to 48 are such that they surround an upper part of the portion 8. An axis 51 is parallel to the vector z and contains the center of the arc 46.

The arcs 42, 44, 46 and 48 respectively have substantially constant radii of curvature m2, m, u, and ns. The radii m and Γ48 are substantially equal and are between 1500 mm and 1700 mm.

The radius Γ42 is between 200 mm and 260 mm. The radius is only between 350 mm and 450 mm.

As visible in FIG. 5, the portion 8 comprises an interior surface 52 and an exterior surface 54. The portion 6 and the rail 30 have been deliberately omitted in FIG. 5 for the same reason as in FIG. 4. The surface 52 is constituted by all the semicircles whose center belongs to the intersection of the plane 11 with the plane formed by the base 40 and extending between two points of an interior contour of the base 40. The surface 54 is constituted by the set of semicircles whose center belongs to the intersection of the plane 11 with the plane formed by the base 40 and extending between two points of an external contour of the base 40. In this way, the portion 8 has substantially the shape of a half-egg.

The material constituting the portion 8 comprises polycarbonate and has a thickness between the surfaces 52 and 54 of between 2 mm and 8 mm. However, it is of course without departing from the scope of the invention to consider another material and / or another thickness. In particular, the material and the thickness are such that the opacity ratio of the portion 8 is between 10% and 80%. In the present application, the expression “opacity ratio” will be understood in accordance with its definition according to standard ISO 2471: 2008, that is to say as the fraction of the reflectance factor with the intrinsic reflectance factor.

In this way, the surface 52 is devoid of a projecting angle and is differentiable and of continuous derivative. In the present application, a surface is differentiable and of continuous derivative if, whatever a line belonging to this surface and whatever a point X belonging to this line, if x is the position of point X on the line and u is the vector normal to the plane tangent to the surface at point X, then the derivative of u with respect to x exists and is continuous. It is of course without departing from the scope of the invention to envisage a different geometry of the portion 8, the surface 52 being devoid of a projecting angle, and preferably a derivable and a continuous derivative.

Referring to Figure 3, the portion 8 has three openings 56, 58 and 60. The openings 56, 58, 60 are respectively located in angular sectors 62, 64, 66. As visible in Figure 3, the sector 62 is delimited by planes 67 and 68. The plane 67 is the plane of the base 40. The plane 68 contains the axis 15 and forms an angle of 21 ° with the plane 67. The sector 64 is between the planes 70 and 72 The plane 70 contains the axis 15 and forms an angle of 35 ° with the plane 67. The plane 72 contains the axis 67 and forms an angle of 52 ° with the plane 67. The sector 66 extends between the planes 74 and 76. The plane 74 contains the axis 15 and forms an angle of 83 ° with the plane 67. The plane 76 is symmetrical to the plane 74 relative to the plane containing the axis 15 and the vector z.

In this way, and taking into account the geometry of the portion 8, whatever a point of the portion 8 contained in the sector 62, the plane tangent to the portion 8 at this point forms an angle between 40 ° and 90 ° . As a result, the opening 56 is adapted to taken in front view. Whatever a point of the portion 8 contained in the sector 64, the plane tangent to the portion 8 at this point forms an angle between 20 ° and 30 °. As a result, the opening 58 is suitable for diving. Whatever a point of the portion 8 contained in the sector 66, the plane tangent to the portion 8 at this point forms an angle less than 10 °. As a result, the opening 60 is adapted to sockets seen from above.

Referring to Figure 1, the opening 60 is frustoconical around an axis 78. More specifically, the intersection of the opening 60 with the surface 54 is a circle having a diameter deosup and the intersection of the opening 60 with the surface 52 is a circle of diameter deoinf. In the example shown, the deosup diameter measures 61 mm and the deoinf diameter measures 59 mm.

The opening 58 differs from the opening 60 in that its section is divided into two semicircles separated by a rectangular portion. Similarly, the opening 56 differs from the opening 60 in that a semicircle of its section is replaced by a rectangular portion. For the openings 56 and 58, the rectangular portion has a width along the direction of the vector y greater as one moves away from the surface 52 and as one approaches the surface 54. In the example illustrated, the rectangular portion has a width along the direction of the vector y equal to deosup at the intersection with the surface 54 and equal to deoinf at the intersection with the surface 52.

Such dimensions of the sections of the openings 56, 58, 60 make these openings suitable for placing the camera 29 facing an opening.

With reference to FIGS. 3, 4 and 5, the device 2 comprises three covers 80, 82, 84 of shapes respectively complementary to those of the openings 56, 58, 60. The diameter or the width according to the direction of the vector becoming smaller there as we get closer to the surface 52 has the effect that the wall defining the openings 56, 58 and 60 forms a chamfer. These chamfers allow the covers 80, 82 and 84 to be held in the position closing the openings 56, 58 and 60 without requiring the use of an additional holding means.

With reference to FIGS. 1 and 2, the device 2 comprises a plate 86. Like the portion 6 and the rail 30, the plate 86 has been deliberately omitted in FIGS. 4 and 5. The plate 86 is planar and perpendicular to the vector z. The plate 86 has the same plane of symmetry as the wall 4. The plate 86 is arranged vertically between the portions 6 and 8, that is to say inside a closed space delimited by the portions 6 and 8 when the portion 8 is in its closed position. The plate 86 and the portion 6 are shown in top view in FIG. 6, the portion 8 and the rail 30 having been omitted for the sake of clarity.

The plate 86 is made of polycarbonate and has a thickness greater than 3 mm. Advantageously, the plate 86 has a thickness less than 1 cm and even more advantageously less than 8 mm. In this way, the plate 86 has an opacity ratio of between 0% and 80%, advantageously between 10% and 70% and even more advantageously between 25% and 35%. Of course, it is possible without departing from the scope of the invention to envisage another material and / or another thickness while respecting the abovementioned opacity ratios.

The plate 86 comprises a fixed part 88 and a movable part 90. The part 90 forms a disc around an axis 92 parallel to the vector z and is received in a corresponding recess in the part 88. The axis 92 is contained in the plane of symmetry of the wall 4 and situated in front of the axis 15. The part 90 is linked to the part 88 by a pivot link around the axis 92.

In the illustrated embodiment, the axis 92 is offset along the direction of the vector x with respect to the axis 51. It is however possible to envisage a more or less significant offset, or else that the axes 51 and 92 coincide. Preferably, the offset remains less than a quarter of the radius Γ46.

As visible in FIG. 6, an outer contour 94 of the plate 86 has substantially the same shape as the base 40. Whatever point X of the contour 94 is, the shortest distance between a point on the base 40 and the point X is noted d min_X · The contour 94 corresponds to the base 40 transformed by a homothety such that the projection of the distance dmin x in the plane perpendicular to the vector z is constant whatever X and greater than 10 mm, preferably between 25 mm and 35 mm, when the portion 8 is in its closed position.

As shown in Figures 1 and 6, the plate 86 has a rounded 96 at the contour 94. It is without departing from the scope of the invention to consider replacing the rounded 96 with a chamfer, or even to provide both a chamfer and a rounding.

With reference to FIG. 4, a plane 100 passes through the axis 51 and is perpendicular to the plane of symmetry 11. A plane 102 passes through the axis 51 and forms an oriented angle of 45 ° with the plane 100 (relative to Figure 4). A plane 104 passes through the axis 51 and forms an oriented angle of -45 ° with the plane 100 (relative to FIG. 4). With reference to FIG. 6, a zone 106 extends outside the part 90 and is delimited by the planes 100 and 102. A zone 108 extends outside the part 90 and is delimited by the plans 100 and 104.

In this way, the zones 106 and 108 correspond to angular sectors between 90 ° and 135 ° with the plane of symmetry 11 around the axis 51 and located behind the axis 51. It follows that the zones

106 and 108 form blind spot zones. The axis 51 thus forms a median axis, that is to say an axis from which the blind spot zones are defined. When it is difficult to define the position of a median axis, for example for a shape different from the base 40, a reasonable approximation is to define the blind spot zones around the axis 92 which is very close to the 'middle axis.

The part 88 is integral with the portion 6. The part 88 is connected to the portion 6 by means of three rods 110. The rods 110 are substantially identical to each other and extend vertically between the portion 6 and a lower surface of the part 88. More specifically, a first rod 110 extends in front of the axis 15 and in the plane of symmetry of the wall 4. The other two rods 110 are located behind the axis 15 and are arranged symmetrically one with respect to the other with respect to the plane of symmetry of the wall 4. The rods 110 disposed behind the axis 15 are respectively located in the blind spot zones 106 and 108.

The rods 110 have a length such that the plate 86 is oriented perpendicular to the vector z. More precisely, the length of the rods 110 is such that the projection along the vector z of the distance dmin x is constant whatever X and between 7 mm and 13 mm.

The device 2 comprises two actuators 112 and 114. The actuators 112 and 114 are vertically disposed below the plate 86. The actuators 112 and 114 are capable of rotating the part 90 relative to the part 88. For example, the actuators 112 and 114 are stepping motors comprising a body (not shown) integral with part 88 and a shaft (not shown) integral in rotation with part 90. As illustrated in FIG. 6, the actuators 112 and 114 are respectively arranged in zones 106 and 108.

To take a plan produced by means of the device 2, a user pivots the portion 8 in its open position. Thanks to the protuberance 18, the portion 8 is stopped and kept in its open position. The user then has a product on the part 90. Then, the user pivots the portion 8 in its closed position. The portion 8 is held in its closed position by contacting the arc 42 of the base 40 on the upper surface of the portion 6.

The user then positions flash projectors 28 on the fixing means 34, 36 and 38. The user removes one of the covers 80, 82 or 84 and positions the camera 29 on the fixing means 32 opposite opening 56, 58 or 60 corresponding to the removed cover. Then, the user synchronously activates the camera 29 and the flash projectors 28 positioned on the fixing means 34, 36 and 38 and on the attachment means 26. This results in lighting through the portion 8 from the wall 4 and through the plate 86 when the product is taken. At the time of the shooting, the product is then optimally lit so that the risk of the appearance of a shadow of the product is minimized. In addition, the closed enclosure delimited by the plate 86 and the portion 8, as well as by the covers 80, 82 or 84 which have not been removed considerably limits the possibility of the appearance of a reflection or a shadow. of an object belonging to the environment of the product or of the device 2. The shape, the design and the relative position of the portion 8 and of the plate 86 further limits the risk of the appearance of a reflection linked to stops or d 'a stop in the background of the product plan.

In view of the above, the device 2 allows any person to carry out a product plan of a product supported by the plate 86, the product plan produced by means of the device 2 being of better quality than the quality of the product plans obtained using conventional devices.
