Multimedia apparatus characterized in that it comprises: - a control unit (100) which comprises an audio/video source and/or is connected to an audio / video source; - a structure (1) for audio/video reproduction connected to said control unit (100) and provided with at least a projector (2), i.e. with means for displaying images (2); said structure (1) being positionable according to different configurations in order to place correspondingly said projector (2), with the possibility of lifting, lowering and / or rotate around a vertical axis the same projector; - a reflecting element (22) adjustable, placed in correspondence of said means for displaying images (2), capable of diverting at least vertically, the projection out from said means for displaying images (2).
Abstract:
A portable device for the storage and display of digital images, using an integrated projector for image display. The device itself might be a camera, smart phone or other portable or handheld electronic device capable of capture or storage of digital images. The integrated projector would allow projection of images at a larger size on an external surface than an internal display would permit. Certain embodiments of the device might also include image capture hardware, in addition to image storage, along with image editing or manipulation software. Method of display of digital images using a portable device with integrated projector is also disclosed.
Abstract:
In order to obtain effects of the increase in brightness of images, miniaturization, low cost, convenience of handling, default prevention, in inconvenience of assembly, which are can be obtained by a projection system, the projection system comprises at least one light-emitting device; a time division supplying device of light that time-divides light emitted from the at least one light-emitting device and supplies it; a first condensing lens that focuses light passing through the time division supplying device of light; a first mirror that reflects light passing through the first condensing lens; an integrator that makes light reflected from the first mirror into a planar light; a second mirror that reflects light passing through the integrator; a third mirror that reflects light reflected from the second mirror to a DMD side; and a projection lens that projects light reflected from the second mirror onto a screen and has an optic axis disposed at both sides of the second mirror and the third mirror, respectively.
Abstract:
Upon bringing a digital camera having a near field wireless communication function close to a projector while a display apparatus displays a screen of a PC using the projector, the display apparatus decodes and displays an image from the digital camera in place of the screen of the PC.
Abstract:
A light guide of the tapered-waveguide type includes an input slab (30) for expanding a projected image between an input end and an output end (40); and a tapered output slab (10) arranged to receive rays from the said output end of the input slab, and to emit them at a point on its face that corresponds to the angle at which the ray is received. The taper is calculated so that all rays injected into the input end undergo the same number of reflections before leaving the output face. The thickness of the input slab light guide (30) is greater in the transverse direction away from the centre line C, so that light travelling at the critical angle from the input face of the slab waveguide towards the output waveguide (10) bounces the same number of times in the input slab, regardless of its fan-out angle, in order to further reduce image distortion.
Abstract:
A rear projection display system and associated optical system are described with a reduced field angle. The rear projection display system includes a screen (20) and a housing. The optical system includes a light engine (102), a first mirror (104), a second mirror (106) and a Fresnel lens (108) arranged to achieve a thin housing. The light engine (102) is generally disposed in an upper region o the housing, and projects light onto the first mirror (104), which can be located at a bottom portion of the housing. The first mirror (104) reflects the projected light onto the second mirror (106), which in turns reflects the light towards the Fresnel lens (108), whic transfers the light onto the screen (20). A total internal reflection Fresnel lens (108) is used to reduce cost and complexity without sacrificing image quality and housing thinness.
