JPH0662346A - Television receiver - Google Patents

Abstract

PURPOSE:To appreciate a television with volume suitable for surrounding environment by automatically controlling volume in accordance with surrounding noise. CONSTITUTION:A television receiver is constituted of an outdoor antenna 2, a station selecting part 3, a video signal processing circuit 4, a video signal changing-over part 5, a display part 6, a voice processing circuit 8, a speaker, an optical sensor 1, a volume sensor 9 and a voice control circuit 7. The volume sensor 9 detects surrounding noise and initially set volume is outputted from the speaker at the time of no surrounding noise. When the volume sensor detects that surrounding noise is increased, the volume control circuit 7 controls the voice processing circuit 8 and volume is increased and outputted from the speaker.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to volume control in a television receiver.

[0002]

2. Description of the Related Art In recent years, various functions have been incorporated along with the increase in size of television receivers, and the functions incorporating a sensor and a control microcomputer have been diversified.

FIG. 2 shows a configuration example of a television receiver using a conventional optical sensor. Here, 1 is an outdoor antenna, 2 is a channel selection section, 3 is a video signal processing circuit, 4 is a video signal switching section, 5 is a display section, 6 is an audio processing circuit, 7 is a speaker, 8 is an optical sensor, 10 is an image. It is a control circuit.

An image sensor 8 built in the television receiver detects the brightness around the television receiver, converts the brightness into an electric signal and outputs the electric signal, and the video control circuit 1
0 controls the video signal processing circuit 3 to control the image quality. For example, when the surrounding brightness is bright, the screen is also brightened, and conversely, when the surrounding brightness is dark, the screen brightness is also darkened. Further, the volume is adjusted by the voice processing circuit 6 and output from the speaker 7.

[0005]

However, in the above-mentioned configuration, the sound of the surrounding environment such as the noise of people in a crowded place such as a lobby or a dining room and the noise caused by the passage of cars or trains along roads or railroad tracks Is difficult to hear.

In view of the above problems, the present invention is to automatically control the volume according to the ambient noise so that the television can be enjoyed at the volume suitable for the surrounding environment.

[0007]

In order to solve the above-mentioned problems, the present invention provides a volume detection sensor, a volume control circuit for converting the detected volume into an electric signal into a control signal, and a television of the television by the control signal. It has a voice processing circuit for adjusting the volume, and changes the volume according to the level of ambient noise.

[0008]

According to the present invention, with the above-described structure, the sound is output at the set volume when the surroundings are quiet, and the volume is increased when the surroundings are noisy. You can enjoy television even in the noise of cars and trains along the road and along the roads.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a television receiver of the present invention.

Here, 1 is an outdoor antenna, 2 is a channel selection section,
3 is a video signal processing circuit, 4 is a video signal switching unit, 5 is a display unit, 6 is an audio processing circuit, 7 is a speaker, 8 is an optical sensor, 9 is a volume sensor, 10 is a video control circuit, and 11 is a voice control circuit. Is.

The volume sensor 9 detects ambient noise, and when there is no ambient noise, the speaker 7 outputs the initially set volume. When the volume sensor 9 detects that the ambient noise has increased, the volume control circuit 1
The audio processing circuit 6 is controlled by 1 to increase the volume and output from the speaker 7.

[0012]

As described above, according to the present invention, the above-described structure outputs the sound at the set volume when the surroundings are quiet, and raises the volume when the surroundings are noisy. You can listen to the sound and enjoy the television even in the noise of people buzzing in the cafeteria, passing by cars and trains along roads and tracks.
