Abstract

The invention relates to a mobile data and/or communication terminal (EG). According to the invention, an optical system (OT), for the generation of a projected display (PD) and a means for stabilisation of said display (PD), on moving the terminal (EG), are provided.

Description

description

Terminal having projection display

The invention relates to a mobile data and / or communication terminal.

Such a terminal is for example a mobile phone or a mobile video camera for still or video Bewegtbil- the. The terminal can also be a small mobile computer.

With video cameras, various methods are applied at the time of image stabilization. In Figure 1, such a method is shown that uses the displaceable lenses. An object OB is in this case processing of a Aufnahmeeinrich- AE, for example, the video camera was added. The receiving device AE has an image sensor BS, for example a so-called C OS chip. The Aufnahmeeinrich- tung AE has an optical lens or a TDC through which the object OB is imaged on the image sensor BS.

During a movement of the receiving device AE results in different image sections BA, as illustrated by means of the solid line and the broken line. The recording device AE does not have motion sensors shown in detail, which capture this movement, and specifically move the optics OT for image stabilization. The image stabilizer prevents ultimately that blurred images are captured with image sensor BS.

The mobile terminals mentioned above generally have for image reproduction or for reproduction of status information and input instructions display devices such as LCDs.

The invention has for its object to improve the handling of mobile terminals with projection displays. This object is achieved by the features indicated in patent claim 1.

The mobile terminal according to the invention comprises a stabilized projection display. During the operation of the terminal using the keyboard built a movement of the projection screen when pressing the buttons can be prevented.

In the following the invention will be described with reference to an illustrated in the drawings embodiment. show Here

Figure 1 is a receiving-side image stabilization in a video camera according to the prior art,

Figure 2 display terminal according to the invention with a projection,

3 shows a further development of the terminal by using a light beam as an indicator medium, and

4 shows a further embodiment of the terminal according to the invention by using a camera.

The terminal shown in Figure 2 according to the invention the EC comprises a projection display PD, wherein the terminal EG via a non-illustrated optical system (OT in Figure 1), an image onto a projection surface such as a white wall projected. The picture may also be achieved through a correspondingly inclined pad on a table.

The projection display PD is generated by a miniaturized projector or a projector using the miniaturized optical system in the terminal EG. The arrangement of this projector is not shown in detail for the invention is of minor importance and in the drawing. The terminal EC according to the invention comprises one or more sensors that are detected on the movements or a Verwack- development of the terminal EG. For example, a correction of the reproducing optical system (OT in Figure 1), these movements are compensated in image reproduction. The movement of the terminal is shown symbolically, for example, by the two double arrows Pl and P2 in two planes. The means for image stabilization, for example, carried out analogously to Figure 1 and not shown in detail in FIG. 2

The terminal device according to the invention is tiltable EC example, in two dimensions by a certain angle without moving the projected image (on the screen) and the projection display PD. This motion compensation is carried switched, for example via a button on the terminal EG. When switched motion compensation, the projected image is adjusted to the chosen projection surface, table or wall. the picture is clamped as it were, by switching on the compensation.

In the embodiment shown in Figure 3 of the invention, the terminal has a so-called laser pointer. This laser pointer, or any other light source that emits a light beam L, which can be positioned by movement of the terminal EG at least within the projection display PD. So details within the projection display PD can be illuminated or marked for example.

Another embodiment of the invention is shown in Figure 4, in which the terminal EG comprises a camera KA. The camera KA serves to receive the projected image or of the image content of the projection display PD and also detects the position of the light beam L. This combination can be treated as an operator input device for the EC. KA from the camera part of the projection display PD is detected, for example, as a camera image. The camera image KB is arranged for example in the lower left half of the projective onsdisplays PD.

The combination of the projection display PD, light beam L and recording via the camera KA enables a user input without a keyboard. The light beam L is moved, for example, an icon in the projection display PD and the same activated. The inventive projection display PD does not force the user to switch the view between a keypad on the terminal EG and the image displayed on the screen or in the projection PD.
