Abstract: An image display unit for displaying still or moving images, this unit having at least one ambient light sensor which is configured to detect a color and an intensity of an ambient light in the surroundings of the image display unit and this unit also having an intensity control device which is configured to adjust the intensity of each individual image point in the images displayed by the image display unit based on the detected color and intensity of the ambient light. Also described is a related mobile phone and a related method.

Abstract: An electrical device having a projection device for projecting image information onto a projection surface disposed externally to the telecommunication device; an inertial sensor to detect a movement of the electrical device; the electrical device being operable in a first operating mode so that the projection of the image information onto the projection surface follows a movement of the electrical device with a movement component in a plane disposed in parallel to the plane of the projection surface; the electrical device being operable in a second operating mode so that, in spite of the electrical device's movement, the projection of the image information onto the projection surface with a movement component in a plane parallel to the plane of the projection surface is at least partially substantially fixed; the electrical device being configured so that its movement in the second operating mode is interpreted as a user input.
