Content projection system Field of the invention
The invention generally relates to projecting content on a projection screen comprising one or more screen panels 5 and, in particular, though not necessarily, to a system and a method for projecting content on a projection screen comprising one or more screen panels, a front projection screen and a projector for use in such system and a computer program product for use with such method.
10
Background of the invention
Nowadays digital projections systems are versatile tools for displaying content on a screen. Because the size of 15 the screens can be made very large these systems are very attractive display systems for use in the field of advertisement. In order for such projection systems to be a commercially attractive alterative to other types of display systems, e.g. liquid crystal display or plasma type screens, 20 the display quality should be better or at least equal to such technologies and, preferably, provide additional user experience.
One type of projection systems for use in advertisement relate to projection systems, typically back 25 projection systems, wherein content is projected on a thin- film transparent layer which can be attached to a window of a shop. The user experience delivered by such system is however rather limited. The relatively thin transparent screen can only provide a limited color intensity and contrast so that 30 especially in bright daylight environments the display quality is limited. Further, the displayed content has strong two-dimensional characteristics. This two dimensional characteristics are may be contributed to the use of a single flat continuous projection screen.
35 It would be advantageous to add value to a display system to give the displayed content a strong three- 2 dimensional appearance so that the impact of the content presentation is enhanced. Further, it may be advantageous to have a display system which is capable of providing the displayed content a three dimensional appearance even during 5 daylight conditions.
Summary of the invention
It is an object of the invention to reduce or 10 eliminate at least one of the drawbacks in the prior art. In one aspect, the invention may relate to a content projection system comprising: a front projection screen comprising one or more screen panels, wherein each screen panel has a projection area of a predetermined shape and wherein each panel comprises 15 projection screen material configured to reflect light projected onto said screen panel by a projector while absorbing light originating from other angles; and, at least one projector for projecting at least part of an image onto said screen panels, said image being projected on said 20 projection screen using one or more shaped apertures, preferably one or more non-linear shaped apertures, dividing said image in one or more shaped image areas that substantially match the shapes of said screen panels.
The content projection system provides value to the 25 projected content by using a projection screen which is divided in a number of shaped, high-contrast screen panels wherein each panel is configured to provide the projected content a three-dimensional appearance. Such systems are particularly suitable in advertisement applications, wherein 30 the screen panels may be shaped in accordance with a desired layout. The high-contrast screen material may provide excellent projection properties at daylight.
In one embodiment at least one of said screen panels may comprise substantially flat main projection area having a 35 front and a back side and a curved peripheral projection area, said curved peripheral projection area being curved in a direction away from said front side, said curved peripheral projection area providing an image projected onto said screen 3 panels a three-dimensional appearance. The curved peripheral projection areas together with the high-contrast screen projection material provides the content projected onto the projection screen a three-dimensional appearance thereby 5 greatly increasing the impact of the content presented. This impact is especially increased when using a projection screen comprising two or more separately projected screen panels.
In another embodiment said image may be encoded in an image data structure. Further, the image data in said image 10 data structure associated with said peripheral projection area may be provided with shadow and/or bright areas along said peripheral area in order to enhance said three-dimensional appearance. This way the three-dimensional appearance of the content projected onto the screen panels may be further 15 enhanced.
In yet another embodiment said one or more shaped apertures may be generated using a configurable diaphragm, preferably a programmable liquid crystal. In a further embodiment said one or more apertures may be encoded in an 20 aperture data structure, wherein each aperture defines a shaped image area, said shaped area substantially matching its correspondingly shaped screen panel.
In an embodiment said system may further comprise at least one sensor connected to said media player, said sensor 25 being configured to receive an input parameter and said media player being configured to modify said image and/or the appearance of said image on the basis of said input parameter sensed by said sensor.
In another aspect, the invention may relate to a 30 projection screen for use in a system as described above, comprising: one or more screen panels, wherein each screen panel comprises a projection area of a predetermined shape and wherein each screen panel comprises a projection screen material configured to reflect light projected onto said 35 screen panel by a projector while absorbing light originating from other angles; and, wherein at least one of said screen panels comprises a substantially flat main projection area having a front and a back side and a curved peripheral 4 projection area, said curved peripheral projection area being curved in a direction away from said front side, said curved peripheral projection area providing part of an image projected on said screen panels a three-dimensional 5 appearance.
In a further aspect, the invention may relate to least one projector for use in a system according as described, said projector comprising: a configurable diaphragm, preferably a programmable liquid crystal display 10 diaphragm, for generating one or more shaped apertures dividing an image in one or more projection areas that substantially match the shapes of said screen panels.
In yet another aspect the invention may also relate to a method for projecting an image on a front projection 15 screen comprising one or more screen panels, at least one of said screen panels comprises substantially flat main projection area having a front and a back side and a curved peripheral projection area, said curved peripheral projection area being curved in a direction away from said front side, 20 said curved peripheral projection area providing said screen panels a three-dimensional appearance, said method comprising: receiving at least one image data structure for projection on said screen panels; providing one or more shaped apertures for dividing said image in at least one or more shaped image areas 25 that substantially match the shapes of said screen panels; and, projecting said shaped projection areas onto correspondingly shaped screen panels.
In one embodiment, said method may comprise: providing shadow and/or bright areas along said peripheral 30 area in order to enhance said three-dimensional appearance.
In another embodiment, the method may comprise: configuring a diaphragm, preferably a programmable liquid crystal display diaphragm, for providing one or more shaped apertures.
35 In a further embodiment, the method may comprise: providing an aperture data structure associated with an image comprising one or more shaped apertures; overlaying said aperture data structure with said image data structure thereby 5 generating said one or more shaped image areas for projection on onto said correspondingly shaped screen panels.
In a further embodiment, the method may comprise: associating at least part of a first image with a first shaped 5 aperture for defining a first shaped image area and associated at least part of a second image with a second shaped aperture for defining a second shaped image area.

Fig. 2 depicts a schematic of a projection system according to another embodiment of the invention.
Fig. 3 illustrates two exemplary aperture arrangements for use in a projection system according to an 30 embodiment of the invention.

Detailed description 35 6 FIG. 1A and IB depict a schematic of a content projection system according to one embodiment of the invention. In particular, Fig. 1A describes a front projection system comprising a digital content projector 102, e.g. a 5 liquid crystal display projector or a projector based on a digital micro-mirror array device. A media player 104 may provide content, e.g. pictures, video, etc. to the digital projector which is provided with one or more light sources and optical lens system for projecting the digital content onto a 10 screen. The content may be formatted in a particular data structure in accordance with well known content format standards, e.g. MPEG, JPEG, etc. The projection screen may be divided in a number of screen panels 108i_4,110 of a particular shape. In one embodiment, the shape of a screen panel may 15 comprise one or more non-linear, i.e. curved parts in order to form a desired shape. Further, a screen panel may comprise one or openings of a desired form. This way, screen panels may be shaped to form of one or more letters. A number of screen panels thus may form a projection screen in the form of a 20 trademark (e.g. screen panels 108i_4 in Fig. 1A) . Other possibilities include a logo, a symbol (e.g. screen panels 110 in Fig. 1A), or any other desired shape, e.g. the shape of a particular product. Preferably, a screen panel comprises two or more of shaped screen panels which together form a 25 particular layout for use in advertisement.
In order to project content onto the shaped screen panels, optical apertures are used. In Fig. 1A, a possible aperture layout 111 is depicted comprising apertures areas 112i_4,114, which comprise one or more non-linear (curved) 30 parts and which are shaped in accordance with the shape of the display panels. In this particular embodiment, the area 116 outside the aperture areas is configured to substantially block light so that when used in the projector system, so that content will only be projected onto the screen panels and not 35 on the wall to which the screen panels are mounted. Hence, by optically aligning the projector with the projection screen, shaped image areas 118,120 generated by the apertures will substantially match the shape of the screen panels.
7
In one embodiment, the aperture layout for defining the shaped image areas may be generated using a configurable diaphragm 117 which may be inserted in the optical system of the digital projector. Such configurable diaphragm may for 5 example relate to a programmable LCD diaphragm wherein transparent aperture areas and light-blocking areas outside the aperture areas may be set by programming pixels in an LCD array.
In another embodiment, the content may be processed 10 or pre-processed using an aperture image layout comprising shaped apertures which substantially match the shape of the screen panels. For example, in one embodiment, a processor 119 in the media player and/or a processor 121 in the digital projector may use an aperture data structure as an overlay 15 over the content. By processing the image data together with the aperture data, the resulting image data comprise shaped image areas matching screen panels.
The screen panels may be configured as front-projection screens comprising a main projection area 122 and a 20 peripheral projection area 124 enclosing the main projection area and defining the edge of a projection screen. Fig. IB depicts a cross-section of a screen panel. The screen panel comprises a reflecting layer 126, which may be covered with one or more further layers. In one embodiment, such layers may 25 include at least one light absorbing layer 128 for absorbing diffusive off-axis light, e.g. daylight and light originating from other diffusive sources. In another embodiment, such layers may further include one or more refracting layers 130 comprising arrays of optical micro-refractive elements, e.g.
30 micro-lenses and/or micro-gratings. Combining such layers will result in a high-contrast screen material.
Fig. IB further illustrates that the peripheral projection area is curved in a direction away from said front side. When content is projected onto the screen panels, the 35 peripheral projection portions will provide the content imaged onto the screen panel a three-dimensional appearance. Hence, the projection system as depicted in Fig. 1A and IB thus provides a versatile content projection system providing value 8 to the projected content by using a projection screen which is divided in a number of shaped, high-contrast screen panels wherein each panel is configured to provide the projected content a three-dimensional appearance. Such systems are 5 particularly suitable in advertisement applications, wherein the screen panels may be shaped in accordance with a desired layout. The high-contrast screen material may provide excellent projection properties at daylight.
Further, the media player and/or digital projection 10 screen may be connected via one or more networks (not shown) to a content provider 132. This way, installed projection systems may thus be simply updated with new content.
Fig. 2A and 2B depict result of content being projected onto a projection screen using a projection screen 15 as described with reference to Fig. 1. Using a number of individually shaped screen panels 208i_4,210, each comprising a main projection area and a curved peripheral projection area, the content projected onto the projection screen will get a three-dimensional appearance thereby greatly increasing the 20 impact of the content presented.
In this particular embodiment, the system may further comprise one a sensor 204 for sensing e.g. movement, temperature, a mobile phone, etc. and on the basis of the measured parameter the system may select and/or modify the 25 content projected on at least one of the screen panels. For example, as depicted in Fig. 2A the sensor may detect movement of a person in the vicinity of the sensor and send a sensor trigger message to the processor in the digital projector 202. In response to the trigger message, the processor may select 30 to display different content on the screen panels. In this example, the content may relate to a weather forecast or the news headlines or the like. This content may be retrieved from the Internet or a separate content provider.
It is to be understood that the invention is not 35 limited to Fig. 2A and 2B but many different embodiments are possible without departing from the invention. For example, upon a sensor trigger and/or a signal from a user interface, the processor in the digital projector may change the content 9 projected on only a few of all the screen panels building the projection screen. Further, in response to a sensor trigger, e.g. a temperature sensor, the processor may modify the color of the content in accordance with the temperature (e.g. from 5 blue (cold) to red (hot)).
Fig. 3A and 3B depict two exemplary aperture layouts for use in a projection system according to further embodiments of the invention. Fig. 3A depicts an aperture layout which is similar to the one depicted in Fig. 1. In this 10 case however, the areas along the edges of the aperture area are providing with contrast information, in particular shadow and/or bright areas 302,304 extending along the edges of the aperture areas. When such aperture layout is for example encode in an aperture data structure and processed together 15 with image data, the content projected onto the screen panels will comprise these shadow and/or bright areas along the peripheral image projection areas of the screen panels. This way the three-dimensional appearance of the content projected onto the screen panels may be further enhanced.
20 Fig. 3B depicts a further way of enhancing the appearance of the projected content. In this embodiment, the aperture areas may have a similar layout as described with reference to Fig. 3A. In this embodiment however, the wall area 306, i.e. the area outside the aperture area, is not 25 completely black, but will be partly transparent for certain areas. For example, in Fig. 3B the aperture area is configured such that the outer edges of the wall area will be projected onto the wall in the form of a square "frame". Content and the aperture layout may be processed in such the frame is 30 projected in a particular color around the screen panels on which the content is projected. The wall area may be defined to gradually become less transparent towards its center of the frame thereby providing the impression of depth.
Fig. 4 depicts a flow diagram 400 of a method for 35 projecting an image on a projection screen according to one embodiment of the invention. The process starts by the digital projector receiving at least one image data structure, e.g. an image frame, for projection on the shaped screen panels (step 10 402). Then, an aperture layout comprising one or more, preferably two or more, shaped apertures is provided (step 404). On the basis of the aperture layout an image is divided in one or more, preferably two or more, shaped image areas 5 that substantially match the shapes of said screen panels (step 406) (wherein the digital projector is optically aligned with the screen panels). Finally, the image shaped in accordance with the shaped projection areas is projected on to the screen panels (step 408).
10 In the process above, in one embodiment, the aperture layout is encoded in an aperture data structure, which may be used to configure a diaphragm, in particular a liquid crystal display diaphragm. In another embodiment, such aperture data structure may be used in a signal processing step wherein the 15 aperture data and the image data are added such that areas in the aperture layout which are black light is substantially blocked.
It is to be understood that any feature described in relation to any one embodiment may be used alone, or in 20 combination with other features described, and may also be used in combination with one or more features of any other of the embodiments, or any combination of any other of the embodiments. Moreover, the invention is not limited to the embodiments described above, which may be varied within the 25 scope of the accompanying claims.
