[0001] The present invention relates to a signage assembly. More particularly, but not exclusively
the invention relates to a signage assembly of a type used to display advertising
materials at sporting events.
[0002] At many sporting events spectators are located about a periphery of a field of play.
Typically, the spectators are seated in tiered seats around the periphery of the field
of play. There is often a barrier separating the spectators from the field of play
so as to allow effective spectator management and to ensure the safety of the spectators
and the sportspeople involved in the sporting event. Such arrangements are common
in sports including football, soccer, and rugby amongst many others.
[0003] It is now commonplace to site advertising boards at the location of the barrier.
Advertisements are placed on such advertising boards so as to face the field of play
and so as to be visible to spectators located at an opposite side of the field of
play. On the basis that the display of advertisements on such advertising boards generates
income for organisers of sporting events, it is advantageous that the advertising
boards should be as large as possible so as to maximise both the number of individual
advertisements and the size of those advertisements. In practice, the height of advertising
boards is limited by the likely eye-line of spectators sitting in the seats located
closest to the field of play - the advertising boards clearly cannot extend above
the eye-line of those spectators or else those spectators would be unable to view
the sporting event. As such the location (particularly the height) of seating represents
a restriction on the height of the advertising boards and therefore the available
advertising space
[0004] It is an object of the present invention to obviate or mitigate at least some of
the problems set out above.
[0005] According to a first aspect of the invention, there is provided a signage assembly
comprising a first signage component defining a first surface displaying a first sign
viewable from an intended viewing position and a second signage component defining
a second surface displaying a second sign. The second signage component is arranged
relative to the first signage component such that the first and second surfaces are
non-parallel and the second sign comprises a manipulation of an original image, the
manipulation being arranged such that, when the signage assembly is viewed from the
intended viewing position, the original image appears in a plane extending at an angle
to the second surface.
[0006] The invention therefore provides a method whereby the second sign is depicted on
a second surface extending from the first surface. The second sign is a manipulation
of original artwork such that the original image appears to extend out of the second
surface. For example, by appropriately transforming the original image the original
image may appear to extend out of the second surface so to appear as to be co-planar
with the first sign. That is, the first sign may appear within the plane. In this
way the provision of the second signage component (which is non-parallel with the
first signage component) allows the original image to be viewed as co-planar with
and above the first sign even though it does not, in physical terms, extend above
the first signage component. It is therefore possible to increase space for the display
of advertisements without increasing the overall height of a signage assembly.
[0007] In use, the first signage component may be positioned so as to extend generally perpendicularly
from a ground surface such that the first signage component has a first edge adjacent
to the ground surface and a second edge distal to the ground surface and wherein the
second signage component is arranged adjacent to the second edge of the first signage
component. The original image may appear in a plane extending at an angle to the second
surface and above the first signage component.
[0008] Either or both of the first and second signage components may be generally planar.
Either or both of the first and second signage components may define respective planes
in which the first sign and second sign are respectively located.
[0009] The plane (i.e. the plane in which the original image appears) may extend from said
first surface at an angle of 0 to 45 degrees. That is, the original image may appear
to extend directly upwards from the first signage component or may be angled relative
to the first signage component at an acute angle. The plane may extend from the first
surface at a small angle. For example an angle of less than 10 degrees, or in some
embodiments an angle of less than 5 degrees.
[0010] The first surface may be located in the plane (i.e. the plane in which the original
image appears). Each of the first and second surfaces may define a respective plane.
[0011] The first and second surfaces may be generally perpendicular to one another. That
is, put another way, an angle measured from the first surface displaying the first
sign to the second surface displaying the second sign may be 270 degrees. Alternatively,
the angle measured from the first surface to the second surface may be a reflex angle,
for example an angle of more than 180 degrees but less than 270 degrees.
[0012] The first surface may extend generally perpendicularly to a ground surface, and the
second surface may extend generally perpendicularly to the first surface such that
the second surface extends generally parallel to the ground surface.
[0013] The manipulation of the original image may comprise one or more of an inverse perspective
transformation, a stretching process and a skewing process.
[0014] The first signage component may comprise a plurality of image elements, the image
elements being programmable so as to cause display of the first sign. Such image elements
may be LEDs. The first signage component may generally be an electronically programmable
signage component which is configured to receive data defining an image and display
such received data. The first signage component may take other forms in some embodiments
of the invention.
[0015] The second signage component may comprise a print carrier on which the second sign
is printed. Additionally or alternatively the second signage component may comprise
a plurality of image elements, the image elements being programmable so as to cause
display of the second sign, for example the image elements may be LEDs. Where the
signage components are programmable the second sign may be modified in real time,
for example based upon an actual viewing position. For example, during a sporting
event the camera that is used to capture the sporting event may change or the position
or orientation of a camera used to capture the sporting even may change such that
the actual viewing position of the sign will also change. In such an embodiment the
actual viewing position may be fed back to the second signage component and the image
displayed on the second signage component may be updated in real time using the actual
viewing position as the intended viewing position to generate manipulated image data
that is optimised for viewing from the actual viewing position.
[0016] The first signage component may be located at or near the periphery of a playing
field for a sporting event. The first signage component may extend generally perpendicularly
to a surface of said playing field.
[0017] The intended viewing position maybe a position of a moving picture camera. In this
way the original image maybe visible in the plane in images generated using the moving
picture camera.
[0018] The first sign may be an advertisement or informational message. The original image
may be an advertisement or informational message.
[0019] The first sign may comprise a first portion of an overall image. The second sign
may comprise a manipulated form of a second portion of the overall image (i.e. the
original image may be the second portion of the overall image). In such a case when
the signage assembly is viewed from the intended viewing position, the overall image
may be perceived to lie in a single plane and may appear to be contiguous.
[0020] An embodiment of the present invention is now described, by way of example, with
reference to the accompanying drawings, in which:
Figure 1 is a schematic plan-view of a stadium for a sporting event;
Figure 2 is a three-dimensional view of a signage assembly in accordance with an embodiment
of the invention;
Figure 3 is a cross-sectional view of the signage assembly of Figure 2;
Figure 4 is an illustration of an original image to be applied to part of the signage
assembly of Figure 3;
Figures 5 and 6 are illustrative manipulated forms of the original image of Figure
4.
[0021] Referring to Figure 1, there is illustrated a stadium 1 designed to hold sporting
events. The stadium provides a field of play 2 in its centre, and spectator areas
3 about its periphery in which spectators typically sit to watch a sporting event
taking place on the field of play 2. Advertising boards 4 are typically located between
the field of play 2 and the spectator areas 3. The advertising boards are oriented
such that advertisements are displayed on a side of the advertising board adjacent
to the field of play 2 so as to be visible to spectators located on an opposite side
of the stadium 1.
[0022] Figures 2 and 3 show one of the advertising boards 4. The illustrated advertising
board takes the form of a signage assembly comprising a first signage component 5
and a second signage component 6. The first signage component is positioned so as
to extend vertically from and perpendicularly to a ground surface 7 of the stadium
1. In the illustrated embodiment the first signage component 5 takes the form of an
LED sign. The LED sign comprises a plurality of LED image elements and is arranged
to receive image data from a controller device and display the image data by appropriate
illumination of the LED image elements. The image data received may be a still image
or may alternatively be a moving image. The image data typically represents one or
more advertisements.
[0023] The second signage component 6 is a planar signage component which is arranged perpendicularly
to the first signage component 5. It can be seen that an angle between a display surface
of the first signage component and a display surface of the second surface component
is 270 degrees. In alternative embodiments, described below, different arrangements
of the first and second signage components relative to one another may be provided.
[0024] In one embodiment the second signage component is a print carrier carrying an image
which is placed on a generally horizontal surface mounted to and extending from the
first signage component 5. In other embodiments the second signage component is adapted
to be affixed to the first signage component 5 so as to generally perpendicularly
extend therefrom.
[0025] The second signage component is arranged to display a second sign. The second sign
is a manipulated form of an original image, the manipulation being arranged to create
an illusion that the original image extends from and out of a surface of the second
sign. For example, the original image may be seen to extend perpendicularly from an
edge 8. That is, to spectators the original image may appear directly "above" the
first signage component 5.
[0026] The manipulation of the original image can take any form which has the result that
the original image extends out of the surface of the second sign. Such manipulations
often involve a manipulation so that the original image has a desired appearance (e.g.
to extend from the edge 8) from a particular viewing position. Suitable manipulations
include stretching and skewing operations and inverse perspective transformations
as are now described with reference to Figures 4, 5 and 6.
[0027] The original image of Figure 4 to be transformed comprises text "3D IMAGE 3D IMAGE"
and Figures 5 and 6 show transformations of the text of Figure 4 using stretching
and skewing as shown in Figure 5 and inverse perspective, sometimes referred to as
reverse perspective, as shown in Figure 6.
[0028] Referring first to Figure 5, the text of the manipulated image has been stretched
and skewed relative to the text of the original image. In particular, as illustrated
in Figures 4 and 5, the image data of the original image lies in a plane having a
first dimension 10 and a second dimension 11 with an angle of 90° between the first
and second dimensions. The image data of the original image is manipulated such that
a line in the original image extending at an angle of 90° to the second dimension
in the original image, that is extending parallel to the first dimension 10, extends
at an acute angle β to the second dimension in the manipulated image. The first dimension
in the manipulated image can therefore be considered as angled acutely relative to
the first dimension in the original image. The angle β is generally determined based
upon the intended viewing position.
[0029] Furthermore, the manipulation of the image data of the original image lengthens the
image data in the first dimension 10 such that a line extending in the (acutely angled)
first dimension in the manipulated image has a length greater than that of a corresponding
line extending in the first dimension in the original image. The stretching and skewing
therefore manipulates generally rectangular shapes in the original image to generally
rhomboid shapes that are stretched in the direction of the first dimension 10 in the
manipulated image and has a corresponding effect on other shapes in the original image.
[0030] Referring to Figure 6, the text of the manipulated image has been transformed according
to an inverse perspective transformation based upon an intended viewing position.
In particular, the manipulation of the original image of Figure 4 to generate the
manipulated image of Figure 6 is based upon a projection from the intended viewing
position through the original image which is such that points of the original image
that are relatively far from the intended viewing position are scaled so as to be
larger in the manipulated image than points of the original image that are relatively
close to the intended viewing position. For example, the manipulated image of Figure
6 is based upon a projection from an intended viewing position to the front left of
the manipulated image such that the number "3" in the image that lies relatively close
to the intended viewing position is relatively small as compared to the final letter
"E" of the image that lies relatively far from the intended viewing position and is
therefore relatively large. Inverse perspective transformations are described in further
detail in expired European Patent Publication Number
0968495.
[0031] It has been explained in the preceding description that the second signage component
6 is arranged perpendicularly to the first signage component 5. That is, the angle
α (Figure 3) is 90 degrees (or, put another way, an angle between the display surfaces
of the first signage component 5 and the second signage component 6 is 270 degrees).
However in some embodiments the angle α may be greater than 90 degrees (i.e. the angle
between the display surfaces may be less than 270 degrees. The arrangement of the
second signage component 6 at an angle greater than 90 degrees may increase the visual
effect that the original image is co-planar with the first signage component 5. It
will be appreciated that there is a trade off between the overall height of the signage
assembly (which increases as the angle α increases) and effectiveness of the image
manipulation. It may be possible to achieve a sufficient visual effect by allowing
the second signage component to extend at 90 degrees and this may be preferred to
minimise the overall height of the signage assembly and thereby minimise the effect
of the signage assembly on the spectator seating. In some cases it may be desired
to limit the overall height of the signage assembly so that it does not obstruct the
view of spectators seated in the spectator seating. In such cases the angle α can
be chosen so as to balance the overall height with the effectiveness of the image
manipulation.

that various modifications can be made to the described embodiments.
