Abstract

A remote control unit for an objective and a camera comprises a base part, an operating element movable relative to the base part, an evaluation and control unit for generating a control signal in accordance with the position of the operating element and an output device for outputting the control signal to an associated camera. The evaluation and control device is adapted to control a feedback device of the control unit in dependence on the position of the operating element to generate at least one feedback signal perceivable by a user.

3. A remote control (10) in accordance with claim 1,

wherein the evaluation and control element (50) is adapted to control the feedback device in dependence on the position of the operating element (18) to generate different feedback signals.

4. A remote control unit (10) in accordance with claim 3,

wherein the evaluation and control device (50) is adapted to control the feedback device to generate a first feedback signal on a reaching of a predefined first position of the operating element (18) and to control the feedback device to generate a second feedback signal which differs from the first feedback signal on a reaching at least one of a predefined second position of the operating element (18) and a predefined positional difference of the operating element (18) relative to the predefined first position.

5. A remote control unit (10) in accordance with claim 1,

wherein the evaluation and control device (50) is adapted to control the feedback device over at least a range of different positions of the operating element (18) relative to the base part (12) to generate the at least one feedback signal.

6. A remote control unit (10) in accordance with claim 1,

wherein the feedback device comprises a vibration device (42) adapted to generate at least one vibration signal feelable by the user of the remote control unit.

7. A remote control unit (10) in accordance with claim 6,

wherein the vibration device (42) is arranged at an outer side of the base part (12) or at an outer side of the operating element (18).

8. A remote control unit (10) in accordance with claim 1,

wherein the feedback device comprises an illumination device (22) adapted to generate at least one illumination signal visible to a user of the remote control unit.

9. A remote control unit (10) in accordance with claim 8,

wherein the illumination device (22) is adapted to illuminate a part of the remote control unit (10) in accordance with a base illumination characteristic;

and wherein the at least one illumination signal has an illumination characteristic differing from the base illumination characteristic, in particular a different color or brightness.

10. A remote control (10) in accordance with claim 8,

wherein the remote control unit (10) has a display device (16) for displaying at least one symbol (24, 26, 28) whose position or value corresponds to the position of the operating element (18) or to a desired position of the operating element (18), with the illumination device (22) being adapted to illuminate the display device (16) partly or completely.

11. A remote control unit (10) in accordance with claim 10,

wherein the illumination device (22) is adapted to generate background lighting for the display device (16).

12. A remote control (10) in accordance with claim 10,

wherein the remote control unit (10) has a masking device (48) which has at least one transparent or partly transparent section and one light-impermeable section in order to transmit or to screen the illumination of the display device (16) generated by the illumination device (22) for different emission directions of the illumination or for different regions of the display device (16).

13. A remote control (10) in accordance with claim 12,

wherein the masking device (48) has a continuous progression of a change in the degree of transparency between the transparent or partly transparent section and the light-impermeable section.
