Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a television device that automatically changes the values of user controls such as volume and picture.

[Summary of the invention] The present invention provides user information regarding video and audio according to the 11th hour.
By automatically varying the control values, it is possible to obtain video and audio conditions that match the external environment without manual operation by the user.

[Prior art and problems to be solved by the invention] Conventionally,
Some devices are equipped with a light intensity sensor that detects the brightness of the room, and use the output of this light intensity sensor to determine whether it is day or night and automatically vary the picture control values.

However, the only object for which user control values should be varied depending on the external environment is pictures.For example, taking into account noise in the neighborhood, the volume should be lower at night than during the day. Since the brightness of the screen is not uniform between day and night, it is not necessarily preferable to control the picture using a light intensity sensor, and it is also impossible to control anything other than pictures using the light intensity sensor.

Therefore, the present invention focuses on the fact that time is the most suitable standard for determining the external environment such as brightness and noise, and provides a television device that can automatically obtain video and audio conditions according to the external environment. The task is to do so.

[Means for Solving the Problems] A television device of the present invention for achieving the above-mentioned problems sets the set values of a clock for measuring time and user controls regarding video and/or audio for one controlled object. The device is equipped with a plurality of memories for storing a plurality of memories, and a control circuit that selects a set value of the memory according to the time of the clock and changes a control value of a video processor and/or an audio processor to the selected set value. .

[Operation] User control values of the video processor and audio processor are controlled according to time, and the video state and audio state are varied.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

An embodiment of the present invention is shown in FIGS. 1-4.

FIG. 1 shows a circuit block diagram of a television device. In FIG. 1, a broadcast signal received by an antenna 1 is input to a VIF tuner 2, where a broadcast signal of a predetermined frequency is selected.

A video signal of the broadcast signal selected by the VrF tuner 2 is extracted by a filter 3, and the extracted video signal is guided to a video processor 4. In addition, the broadcast signal of the VIP tuner 2 is passed through a band pass filter (BPF) 5.
An audio signal is extracted at , and this extracted audio signal is led to an audio processor 6 . The video processor 4 is configured to perform predetermined signal processing and to control video such as picture, brightness, color, sharpness, etc. using control signals from the control circuit IO. The output of the video processor 4 is led to a CRT 7. The audio processor 6 performs predetermined signal processing and adjusts the volume.

Control circuit 1 controls audio such as heavy bass and surround sound.
0 control signal. The output of the audio processor 6 is guided to a speaker 9 via an amplifier 8.

The control circuit 10, video processor 4, audio processor 6, memory 11, etc. are connected by a path line 12. The memory 11 is composed of a RAM, and writing and reading are controlled by a writing/reading control signal from a control circuit IO. This memory 11 stores respective set values of daytime data (vA) and nighttime data (Va) regarding video picture, bright color, sharpness, etc., audio volume, deep bass, surround, etc. The control circuit IO has a receiving section 10a, and when the receiving section 10a receives a command signal from the remote controller 13, it controls the VIP tuner 2 and the like based on this command signal. or,
The control circuit 10 includes a clock 10b for measuring time, and executes the flowcharts shown in FIGS. 3 and 4. That is, in the preset mode, the day data (vA) and night data (ve) can be updated, and in the normal operation mode, the control values of the video processor 4 and audio processor 6 are set according to the time when the power is turned on, and the control values are updated from daytime. At night or when transitioning from night to day, a control signal is output to change each of the above control values.

The operation of the above configuration will be explained below.

Select the preset mode as shown in Figure 3j,
When daytime data (VA) and nighttime data (Ve) of each control value are input, this input data is stored at the address of the control value in the memory 11. This allows the user to freely set desired daytime data (■^) and nighttime data (v8).

As shown in FIG. 3, when the power is turned on, the clock 10b
Check the time of day, and if it is daytime section, check daytime data (VA
) is read from memory +1, and each control value of video processor 4 and audio processor 6 is daytime data (vA).
is set to If it is a night section, the night data (V,) is read from the memory II, and each control value of the video processor 4 and the audio processor 6 is set to the night data (v8).

Then, the time on the clock tab is checked, and when the day section shifts to the night section, the night data (VB) is read from the memory 11 and each control value of the video processor 4 and audio processor 6 is updated to the night data (V a). do. When transitioning from the night section to the day section, each of the above control values is converted to daytime data (V
A), and the relationship between time and control value becomes as shown in FIG. Daytime data (VA) and nighttime data (vB)
The switching may be carried out gradually as shown by the solid line in FIG. 2, or may be switched all at once as shown by the dashed line in FIG. In this way, the day is divided into a day section and a night section, and the picture, volume, etc. are set in the day section by the day data (VA), and in the night section, the night data (VA) is set.
), the picture, volume, etc. are set, so you can obtain video and audio conditions that match the external environment.

Note that in this embodiment, regarding video, pictures,
Brightness, color, sharpness, etc. are to be controlled.
Regarding the audio, the volume, deep bass, surround, etc. are controlled, but depending on the case, only one of the video and the audio, or only a specific part of the video and the audio may be controlled.

Furthermore, in this embodiment, -day is divided into two sections, a day section and a night section, but it may be divided into three or more sections as necessary.

Furthermore, in this embodiment, the control values of the video processor 4 and the audio processor 6 are controlled not only when the power is turned on, but also when the TV is driven from a daytime period to a night period or from a night period to a daytime period. Although it is configured to be variable, if it is considered undesirable for the video state or audio state to change while watching television, the data may be configured to be set only at the time when the power is turned on.

[Effects of the Invention] As described above, according to the present invention, the user control values for video and audio are automatically varied depending on the time, so the video state and the audio can be adjusted according to the external environment without manual operation by the user.
