1. A device for displaying moving images in a motor vehicle, comprising:
- a moving image source;
a screen configured to display moving images, wherein the screen is coupled to the moving image source; and
a control unit for the screen, wherein the control unit is configured to activate the screen in first mode, in which the moving images are displayed with normal playback parameters, and one second mode,wherein a speed sensor connected to the control unit, wherein the speed sensor is configured to detect a speed of the motor vehicle and transmit the detected speed to the control unit,wherein the control unit is configured to select the first mode if the speed is less than a first threshold value,wherein the control unit is configured to select the second mode if the speed is greater than or equal to a second threshold value that is greater than or equal to the first threshold value,wherein the refresh rate is lower in the second mode than in the first mode,wherein a distance sensor is connected to the control unit, wherein the distance sensor is configured to detect a distance of the motor vehicle from an object located in front of the motor vehicle in a direction of travel or from a vehicle travelling in front, and to transmit the detected distance to the control unit, andwherein the control unit is configured to change the first or the second threshold value according to an isotone function of the distance.

Abstract
A device for displaying moving images in a motor vehicle displays moving images in a first or second mode. In the first mode the moving images are displayed with normal playback parameters and the refresh rate in the second mode is lower than in the first mode. One of the first and second modes is selected based on a speed of the motor vehicle.

9. A method for displaying moving images in a motor vehicle, the method comprising:
-
displaying the moving images in a first mode with normal playback parameters; detecting whether a speed of the motor vehicle is less than a first threshold value or greater than or equal to a second threshold value, which is greater than or equal to the first threshold value; continuing to display the moving images in the first mode is selected if the detected speed is less than the first threshold value; displaying the moving images in a second mode if the detected speed is greater than or equal to the second threshold value that is greater than or equal to the first threshold value, wherein the refresh rate is lower in the second mode than in the first mode; detecting, by a distance sensor, a distance of the motor vehicle from an object located in front of the motor vehicle in a direction of travel or from a vehicle travelling in front; and changing the first or the second threshold value according to an isotone function of the distance. - View Dependent Claims (10, 11, 12, 13, 14, 15)
