Definitions
- the present invention relates to imaging apparatus and in particular to the decoupling and docking arrangements of a decouplable image projection device that can be used with different types of docking stations.
- Image projection apparatus have been known for a number of years and fall into two distinct categories, the rear, and forward projection types.
- a conventional television receiver is a rear projection apparatus
- a conventional cinema projector is a forward projection apparatus.
- projection apparatus are seldom, moved and typically a business or home or entertainmenL venue may end up purchasing and owning several different projection apparatus located in different areas for different uses even though they may not all be used at the one time. Having multiple projection apparatus may not be too inconvenient, but it is rather an expensive option.
- One of the most expensive parts in a projection apparatus is the optical engine that produces the image subsequently projected.
- Some image projection devices use a Liquid crystal Display (LCD) or other similar display devices. These can degrade through exposure to ultra-violet rays, high heat, or cigarette smoke, requiring upgrades, or replacement of the LCD. This can be somewhat difficult and cumbersome to cany out and in some cases not even possible requiring replacement of the whole unit or at the very least expensive repair. In many image projection devices upgrades or replacement LCD's or other similar display devices need to therefore be carried out by specialists. It is an object of the present invention to overcome at least some of the aboveme ⁇ tioned problems or provide the pubic with a useful alternative.

- Figure 5 illustrates two decouplable image projection devices 44 and 46 that may be coupled to produce one complete image 48. This may be appropriate where one would require to project an image over a larger surface area so that it needs to be projected in iwo parts, each part by a separate decouplable image projection device 44 and 46.
- four decouplable image projection devices 10a, 10b, 10c, and lOd may be used to provide four images directed in four different directions.
- the four decouplable image projection devices may be used in a rear projection apparatus providing four right-angled images 48a, 48b, 48c, and 48d. This type of arrangement may be particularly useful in a large entertainment venue or a retail outlet where an image is to be provided in different directions.
- the four devices xe mounted in a multi docking station 50.
- the present invention provides for either a rear projection or forward projection apparatus by the use of a mountable decouplable image projection device 10, which means that it may be used to provide an image to different types of projection apparatus. Since the decouplable image projection device 10 is removable the cost of the projection unit 16 itself is far less than is conventionally possible for the same number of projection outputs and allows the decouplable image projection device 10 to be used either in the rear 20 or front projection modes 38. Fiuther, the docking station 18 enables a total projection apparatus that has a high degree of interactivity, ruggedisation, and portability, The use of four or more housings allows four images (and thus 360 degrees viewing) to be achieved at the same time. It is also to be understood that the decouplable image projection device 10 may include other features such as speakers mounted on 'wings ⁇
- the docking station 18 includes various connection means including, but not limited to * A computer interface Cdata in)
