Patent ID: 8177368

Claim:
An image display apparatus, comprising: an image source, a mount, an at least partially transparent screen, and a pigmented reflective member, the mount being arranged to retain the screen under tension, such that the screen is inclined at an angle with respect to a plane of emission of light from the image source; the screen having a front surface arranged such that light emitted from the image source is reflected therefrom; and the image source being arranged to provide an image such that light forming the image impinges upon the screen such that a virtual image is created from light reflected from the screen, the virtual image appearing to be located behind the screen, the apparatus further comprising a stage, and a stage background, the screen being provided in front of the stage, wherein a plurality of light sources are arranged to illuminate at least part of at least one of the stage or stage background, and the pigmented reflective member being provided in an optical pathway between the image source and the screen and being operative to reflect only light from part of the visible spectrum such that the pigmented reflective member reduces a milky hue associated with light where there is no image to be presented surrounding a Pepper's Ghost image to compensate for variations in levels of unwanted light hitting the surface of the screen; wherein an angle of inclination of the pigmented reflective member with respect to the plane of emission of light from the image source is variable.
