Abstract

A remote control device for generating setting signals for a lens setting motor of a motion picture camera comprises a base part and an operating element rotatable relative to the base part for setting control commands for the lens setting motor; a position encoder for detecting a respective rotational position of the operating element and generating corresponding position signals; an evaluation and control device that is configured to determine setting signals for the lens setting motor in dependence on the position signals in accordance with a mapping rule; and an output device for transmitting the setting signals to the motion picture camera. In this respect, the mapping rule corresponds to at least one mathematical functional relationship and the remote control device has an input device via which the mathematical functional relationship can be configured by user input. A marking ring for a remote control device has a memory in which a readable coding is stored.

First claim

1 . A remote control device for a lens setting motor of a motion picture camera, the remote control device comprising an operating unit, wherein the operating unit comprises:
a base part; an operating element rotatable relative to the base part about an axis of rotation for setting control commands for the lens setting motor; and a position encoder that is configured to detect a respective rotational position of the operating element relative to the base part and to generate corresponding position signals, wherein the operating element is configured to receive a marking ring in a rotationally fixed coupling for marking the settable control commands, wherein the marking ring is configured to be selectively coupled to the operating element by a user, and wherein the operating unit has a reading device that is configured to read a coding provided by the coupled marking ring.

2 . A remote control device in accordance with claim 1 ,
wherein the operating unit comprises a writing device that is configured to transmit a coding stored in the remote control device to the coupled marking ring.

3 . A remote control device in accordance with claim 1 ,
wherein the remote control device comprises an evaluation and control device that is configured to determine the setting signals for the lens setting motor in dependence on the position signals in accordance with a mapping rule, wherein the evaluation and control device is configured to determine the mapping rule by means of the read coding.

4 . A remote control device in accordance with claim 3 ,
wherein the remote control device comprises a memory for storing a plurality of mapping rules, and wherein the evaluation and control device is configured to select one of the stored plurality of mapping rules in dependence on the read coding.

5 . A remote control device in accordance with claim 4 ,
wherein the operating unit comprises an input device for changing and/or configuring the mapping rule.

6 . A remote control device in accordance with claim 1 ,
wherein the operating unit comprises an evaluation and control device and an electronic display device, wherein the evaluation and control device is configured to display predetermined representation values at the display device, wherein the representation values correspond to respective setting values of a lens of the motion picture camera and are predetermined by the read coding, and wherein the evaluation and control device is configured to define a variable position of the displayed representation values at the display device in dependence on the setting values of the lens, wherein the setting values of the lens are desired values or actual values of a recording parameter of the lens.

7 . A marking ring for marking control commands for a lens setting motor of a motion picture camera that is configured to be selectively coupled to a rotatable operating element of a remote control device for setting control commands for the lens setting motor,
wherein the marking ring is configured to be rotationally fixedly coupled to the rotatable operating element of the remote control device, wherein the marking ring bears a marking of the settable control commands or can be provided with such a marking, and wherein the marking ring comprises a memory in which a coding is stored or can be stored, wherein the memory comprises an interface or is connected to an interface via which the coding can be read and/or can be written.

8 . A marking ring in accordance with claim 7 ,
wherein the memory is surrounded by a waterproof protective cover.

9 . A marking ring in accordance with claim 7 ,
wherein the coding represents an operating data set for the coupled remote control device, and wherein the interface of the memory is configured to cooperate with a reading device of the coupled remote control device in order to read the coding from the memory.

10 . A marking ring in accordance with claim 7 ,
wherein the marking of the marking ring corresponds to a mapping rule for mapping the control commands to respective rotational positions of the operating element, wherein the coding represents the mapping rule.
