Abstract

A display apparatus includes the switching unit for switching between an operating mode and a standby mode. The apparatus generates a picture on a display screen in the standby mode. The apparatus includes, for example a microphone for measuring a sound volume in the vicinity of the apparatus. The microphone is coupled to the picture-generating unit in order to change the picture in the standby mode in response to a change of the measured sound volume.

Claims

1. An apparatus which comprises:

switching means for switching the apparatus between an operating mode and a standby mode;

a display screen;

picture-generating means for generating a picture on the display screen in the standby mode; and

measuring means for measuring a value of a parameter of an environment of the apparatus, coupled to the picture-generating means, in order to change a composition of the picture on the display screen while in the standby mode in response to a change of the measured value.

2. An apparatus as claimed in claim 1, wherein the parameter is a sound signal.

3. An apparatus as claimed in claim 2, wherein:

the measuring means are arranged to measure at least one property of the sound signal, the at least one property being one of a volume, a pitch, and a frequency at which maxima occur in the volume; and

the picture-generating means are arranged to change the picture composition in response to a change of said at least one property.

4. An apparatus as claimed in claim 3, wherein the measuring means are arranged to measure at least two of said properties of the sound signal, and the picture-generating means are arranged to induce a unique, respective change of the picture composition in response to a change of each of the measured properties.

5. The apparatus as claimed in claim 4 wherein the user of the apparatus controls the two said measured properties of the sound signal thereby to control the picture composition in the standby mode.

6. The apparatus as claimed in claim 2 further comprising a microphone coupled to an input of the measuring means and responsive to sound produced in the environment of the apparatus.

7. An apparatus as claimed in claim 1, wherein the picture generating means are arranged to change at least one picture characteristic in response to the change of the measured value, the at least one picture characteristic being one of a color contents, a size of objects displayed and a number of objects displayed.

8. The apparatus as claimed in claim 1 wherein the parameter is a sound signal that is derived from the environment independently of the apparatus.

9. The apparatus as claimed in claim 1 wherein a user of the apparatus can induce a change in the composition of the picture on the display screen while the apparatus remains in the standby mode by causing a change in said parameter and independently of any user operable input devices for the apparatus.

10. The apparatus as claimed in claim 1 wherein the parameter is a sound signal controlled by a user of the apparatus.

11. The apparatus as claimed in claim 1 wherein the parameter is chosen from ambient sound, ambient temperature, ambient light intensity, and spectral composition of ambient light.

12. The apparatus as claimed in claim 1 wherein the picture generating means generates signals in the standby mode for control of the picture composition on the display screen and dependent on the measured values of the parameter supplied to it by the measuring means.

13. The apparatus as claimed in claim 1 wherein the picture generating means generates signals in the standby mode, in response to the measured parameter values, that automatically change the picture composition on the display screen.

14. A television receiver having an operating mode and a standby mode, comprising:

a receiver for receiving and processing video signals received by the television receiver in the operating mode,

a display device for the display of video information,

picture generating means for generating a picture on the display device in the standby mode,

measuring means for measuring a value of a parameter of an environment of the television receiver and coupled to the picture generating means in order to change a composition of the picture on the display device while in the standby mode and in response to a change of the measured value, and

switching means coupled between the receiver and the display device and between the picture generating means and the display device for switching the television receiver between the operating mode and the standby mode.

15. The television receiver as claimed in claim 14 further comprising control means for controlling said switching means from the operating mode to the standby mode, wherein time is not the environmental parameter measured by the measuring means.
