remote source} - H04N 23/633: {for displaying additional information relating to control or operation of the camera} - H04N 23/695: Control of camera direction for changing a field of view, e.g. pan, tilt or based on tracking of objects - H04N: PICTORIAL COMMUNICATION, e.g. TELEVISION ## Abstract The invention relates to a mobile receiver unit (1) for controlling an actuator (2) for setting a pan and/or tilt angle α, β of a camera (3), said unit having a display device 4 to display an image captured by the camera (3), a control device (5) to define control commands for the actuator (2) and a transmitter unit (6) to transmit the control commands to the actuator (2), wherein the control device (5) has a gyroscopic sensor (7) to detect a relative change in angle of the mobile receiver unit (1) around at least one axis A, B, wherein a control command for a relative angle change of the pan angle α and/or the tilt angle β of the camera (3) is determined by the relative angle change, and/or the control device (5) has a compass sensor (8) to detect an absolute angle position of the mobile receiver unit (1) around at least one axis A, B, wherein a control command for an absolute angle setting of the pan angle α of the camera is determined by the absolute angle position. ## Claims ### Claim 1 A mobile receiver unit for controlling an actuator for setting a pan angle, a tilt angle, or both the pan angle and the tilt angle of a camera, the mobile receiver unit comprising: a display device to display an image captured by the camera, a control device to define control commands for the actuator and a transmitter to transmit the control commands to the actuator, wherein the control device has a gyroscopic sensor to detect a relative change in angle of the mobile receiver unit around at least one axis, wherein a control command for a relative angle change of the pan angle, the tilt angle, or both the pan angle and the tilt angle of the camera is determined by the relative angle change, and/or the control device has a compass sensor to detect an absolute angle position of the mobile receiver unit around at least one axis, wherein a control command for an absolute angle setting of the pan angle of the camera is determined by the absolute angle position, wherein the mobile receiver unit is configured in such a manner that, in order to set the pan angle of the camera, the absolute angle setting of the pan angle takes place in a first step and the relative angle change of the pan angle takes place in a second or succeeding step. ### Claim 2 (depends on 1) The mobile receiver unit according to claim 1, wherein the relative change in angle of the mobile receiver unit is detected around a pan axis as the axis from an original state into a pan state and/or around a tilt axis as the axis from an original state into a tilt state, wherein the control command for the relative angle change of the pan angle of the camera is determined by the relative angle change of the mobile receiver unit around the pan axis and/or the control command for the relative angle change of the tilt angle of the camera is determined by the relative angle change of the mobile receiver unit around the tilt axis. ### Claim 3 (depends on 2) The mobile receiver unit according to claim 2, wherein the gyroscopic sensor comprises at least one first and one second gyroscopic sensor, wherein the first gyroscopic sensor is associated with the pan axis and the second gyroscopic sensor with the tilt axis. ### Claim 4 (depends on 2) The mobile receiver unit according to claim 2, wherein the amount of the relative angle change of the pan angle, the tilt angle, or both the pan angle and the tilt angle of the camera is equivalent to the amount of the relative angle change of the mobile receiver unit around the at least one axis. ### Claim 5 (depends on 1) The mobile receiver unit according to claim 1, wherein the amount of the absolute angle setting is equivalent to the amount of the absolute angle position. ### Claim 6 (depends on 1) The mobile receiver unit according to claim 1, wherein the absolute angle position is displayed on the display device. ### Claim 7 (depends on 1) The mobile receiver unit according to claim 1, wherein the mobile receiver unit comprises an operating device, wherein a zoom of the image can be controlled by means of the operating device. ### Claim 8 (depends on 1) The mobile receiver unit according to claim 1, wherein the mobile receiver unit is designed as a tablet or as a mobile telephone. ### Claim 9 A method for operating a mobile receiver unit, wherein a pan angle, a tilt angle, or both the pan angle and the tilt angle of the camera are changed when a relative change in angle of the mobile receiver unit takes place around the at least one axis, and/or wherein the absolute angle setting of the pan angle of the camera is changed when the absolute angle position of the mobile receiver unit is changed, wherein the mobile receiver unit is configured in such a manner that, in order to set the pan angle of the camera, the absolute angle setting of the pan angle takes place in a first step and the relative angle change of the pan angle takes place in a second or succeeding step. ### Claim 10 (depends on 9) A non-transitory, computer-readable medium comprising instructions, when executed on a computer, to carry out the steps of the method according to claim 9. ### Claim 11 A mobile receiver unit for controlling an actuator for setting a pan angle, a tilt angle, or both the pan angle and the tilt angle of a camera, the mobile receiver unit comprising: a display device to display an image captured by the camera, a control device to define control commands for the actuator and a transmitter to transmit the control commands to the actuator, wherein the control device has a gyroscopic sensor to detect a relative change in angle of the mobile receiver unit around at least one axis, wherein the control device has a compass sensor to detect an absolute angle position of the mobile receiver unit around at least one axis, wherein a control command for an absolute angle setting of the pan angle of the camera is determined by the absolute angle position, and wherein the mobile receiver unit is configured in such a manner that, in order to set the pan angle of the camera, the absolute angle setting of the pan angle takes place in a first step and the relative angle change of the pan angle takes place in a second or succeeding step.
