Description

  The present invention relates to a television apparatus, and more particularly to a television apparatus that can prevent an output volume from becoming excessively large when an optical disk to be reproduced is changed.

  In recent years, with the multi-functionality and diversification of playback devices, it has become possible to connect various playback devices to a television device to play back images and sounds. There are also a number of playback multifunction devices in which a playback device and a television device are integrated.

  Optical disks such as DVD media and BD-R media are widely used as recording media used by the above-described playback devices. However, the sound volume recorded on the optical disc has a different reference value for each optical disc. Therefore, when reproducing an optical disc having an extremely small volume reference value, the user needs to make an adjustment by increasing the output volume of the television apparatus.

  However, it is assumed that after playing an optical disc having an extremely small volume reference value as described above, the output volume of the television apparatus is not changed, and the optical disc is replaced with an optical disc having a large volume reference value. In this case, there is a possibility that a large volume unexpected by the user is output from the television device at the start of reproduction. For example, there is a problem in that the residents may be inconvenienced in a densely populated environment such as an apartment house or in a situation such as midnight with low noise.

  In relation to the above, Patent Document 1 discloses an automatic volume / sound quality setting device that automatically obtains a specific volume / sound quality each time a CD or the like is exchanged. This automatic setting device inputs sub-code information other than the music signal recorded on the audio signal recording medium and specific volume / sound quality setting information set for each audio signal recording medium to the control unit. The control unit writes the subcode information and the volume / sound quality setting information in the memory in association with each other. At the time of reproduction, the sound volume / sound quality setting information associated with the subcode information read from the audio signal recording medium is read from the memory and reproduced with the sound volume / sound quality.

  In relation to the above, Patent Document 2 discloses a television receiver capable of setting an appropriate volume when switching a tuner / external input at midnight. The television receiver reduces the gain of the amplifier by a predetermined amount when the current time is within a predetermined time range and when the tuner selection state is switched to the external input state. Further, when switching from the external input state to the tuner selection state, the gain of the amplifier is increased by a predetermined amount.

In relation to the above, Patent Document 3 discloses a television receiver that can automatically reduce the brightness and volume of a video when a preset time is reached. This television receiver can set in advance the time for reducing the brightness and volume of the video by a certain amount. At the set time, the brightness and volume of the video are reduced by a predetermined amount by a predetermined amount.

  However, in Patent Document 1, since the user needs to set and record the volume / sound quality setting information in units of optical disks in advance, there is a problem that it takes time for the user. Further, since it is necessary to record information in which the subcode information and the volume / sound quality setting information are associated with each other, there is a problem that the recording capacity that is required increases as the type of the optical disc increases. Further, since the present invention can be performed only on a music signal recording medium having subcode information, there is a problem that volume adjustment cannot be performed on optical discs of other standards, such as DVD media.

  Further, in Patent Document 2 and Patent Document 3 described above, the function of automatically adjusting the volume according to the change in time is disclosed, but the volume is adjusted when the optical disc to be reproduced is changed by user exchange or the like. There is no disclosure or suggestion of the function to be adjusted.

  The present invention has been made in view of the above-described problems. When the playback target of the optical disk playback apparatus built in the television apparatus or the externally connected optical disk playback apparatus is changed, the volume reference value for each optical disk is changed. A TV with a volume adjustment function that can prevent an unexpectedly high volume output due to the difference between the two, and that does not require a complicated device configuration and processing and can be implemented for all optical disks. It is an object to provide a John device.

The output volume is changed to a predetermined value when it is determined that the threshold is exceeded.

  According to this, the television apparatus of the present invention connects an audio signal output unit (= part of the volume setting means) that outputs an audio signal with an adjusted output volume to a speaker and an external playback device such as a DVD player. An external input unit (= input unit) that inputs information and an image reproduction unit (= image reproduction unit) that generates an image from an image signal are provided. Further, an image detection unit (= image detection unit) is provided that checks an image generated by the image reproduction unit and determines whether the image is a predetermined image. In addition, a volume determination unit (= volume determination unit) is provided for determining whether the output volume set by the audio signal output unit exceeds a predetermined threshold.

  When a predetermined image is detected by the image detection unit, the volume determination unit determines the output volume. As a result of the determination, when the output volume exceeds the threshold, the output volume is set to a predetermined value, for example, an intermediate value between the maximum value and the minimum value. Thereby, when the set value of the output volume is extremely large, the volume can be changed to an appropriate level.

  In order to achieve the above object, a television apparatus according to the present invention comprises an optical disk reproducing means for reproducing an optical disk, and an optical disk detecting means for detecting that the optical disk has been ejected from the optical disk reproducing means. When the optical disc detection unit detects the ejection of the optical disc, the volume determination unit determines whether the output volume exceeds the threshold value, and if it is determined that the output volume exceeds the threshold value, The output volume is changed to a predetermined value.

  According to this, the television apparatus of the present invention includes an optical disk drive for reproducing an optical disk (= optical disk reproduction means) and an optical disk detection unit (= optical disk detection means) for detecting that the optical disk has been ejected from the optical disk drive. ing. When the ejection of the optical disk is detected by the optical disk detection unit, the volume determination unit determines the output volume. As a result of the determination, when the output volume exceeds the threshold, the output volume is set to a predetermined value, for example, an intermediate value between the maximum value and the minimum value. Thereby, when the set value of the output volume is extremely large, the volume can be changed to an appropriate level.

  In order to achieve the above object, the television apparatus of the present invention uses, as the predetermined image, an optical disc ejected image input from an external device connected to the input means or a specific single color image. It is characterized by.

  According to this, the television apparatus of the present invention uses, as the predetermined image detected by the image detecting unit, an optical disc discharge image such as a manufacturer logo displayed when the optical disc is discharged, or a single color image such as a blue back image. Therefore, even when the optical disk drive is externally connected, it is possible to detect using these images that the optical disk has been ejected.

  In order to achieve the above object, a television apparatus according to the present invention includes: an image designating unit that accepts an image designation; and a recording unit that records the image accepted by the image designating unit as a designated image. A specified image recorded in the recording means is used as the image.

Then, the user-designated image when ejecting the optical disk is used as the predetermined image detected by the image detection unit. As a result, even when the externally connected optical disk drive does not output a predetermined manufacturer logo, blue background image, etc. when the optical disk is ejected, the ejection of the optical disk can be detected by the user specifying it in advance. Is possible.

  According to the present invention, when a predetermined image is detected by the image detection unit, the volume determination unit determines the output volume, and when the output volume exceeds the threshold, the output volume is determined in advance. To the correct value. For this reason, even when an optical disk with a low volume is played back with the output volume raised, and then replaced with a high-volume optical disk and played as it is, a loud volume unexpected by the user is output at the start of playback. Can be prevented.

  Further, according to the present invention, when it is detected that the optical disk is ejected from the optical disk drive built in the television apparatus, the volume determination unit determines the output volume, and if the output volume exceeds the threshold, the output volume Is adjusted to a predetermined value. For this reason, when exchanging an optical disk, it is possible to prevent a loud sound unexpected by the user from being output. Further, it is possible to easily and reliably detect the discharge of the optical disk.

  Further, according to the present invention, it is detected that the optical disk has been ejected from the optical disk drive by detecting a single color image such as a manufacturer logo image or a blue back image. For this reason, even when the optical disk device is externally connected and its operation state cannot be confirmed, the open / close state of the optical disk drive is recognized and the volume is detected without providing a new member for detecting discharge. Adjustment processing can be performed.

  Further, according to the present invention, designation of an image displayed when the optical disk is ejected is received from the user and recorded in a recording unit such as a memory. Therefore, even when an optical disk drive that outputs an image other than the manufacturer logo or single color image is externally connected when the optical disk is ejected, it is possible to detect the ejection of the optical disk and perform volume adjustment processing. The versatility of processing can be improved.

  Embodiments of the present invention will be described below with reference to the drawings. In addition, embodiment shown here is an example and this invention is not limited to embodiment shown here.

[Embodiment 1]
<1-1. Internal configuration>
FIG. 2 is a configuration diagram showing the television apparatus 1 according to the first embodiment of the present invention. In addition, the arrow line in FIG. 2 has shown the flow of data. Moreover, the straight line without an arrow has shown the communication bus for the control part 11 to transmit / receive the control signal etc. with respect to each apparatus. The television apparatus 1 includes at least a control unit 11, a memory 12 (= recording unit), an operation unit 13, a broadcast reception unit 14, an external input unit 15 (= input unit), an A / D conversion unit 16, a signal separation unit 17, A D / A conversion unit 18, an audio signal output unit 19 (= part of a volume setting unit), a speaker 20, an image reproduction unit 21 (= image reproduction unit), an image signal output unit 22, and a display 23 are configured. Has been.

  The control unit 11 controls the driving of each member of the television device 1 so as to control the reception of the television broadcast and the display processing of the received television broadcast. For example, the control unit 11 includes a plurality of microprocessors. The control unit 11 is a central part that controls each device, calculates data, processes, and the like. The details of each functional unit (image detection unit 11a to image designation unit 11d) included in the control unit 11 will be described later.

  The memory 12 is a medium for temporarily recording various data held by the television device 1, and is configured by, for example, a writable RAM (Random Access Memory). The memory 12 has a role as a buffer memory for temporarily recording, for example, processing data when various kinds of information processing are performed by the control unit 11 and instruction commands received from the user.

  The operation unit 13 is for the user to give various instructions to the television apparatus 1 for viewing a program and the like. The instruction output from the operation unit 13 is received by the control unit 11. The control unit 11 that has received the instruction performs channel selection processing, volume adjustment processing, and the like based on the content of the instruction.

  The broadcast receiving unit 14 is connected to an external antenna (not shown), and performs digital broadcast or analog broadcast tuning, reception, frequency conversion, amplification, demodulation, and the like. Thereby, an image signal, an audio signal, or the like is obtained from the received broadcast signal. The television broadcast receiver 13 is configured to include an analog tuner, a video intermediate frequency amplifier circuit, a demodulator circuit, an amplifier circuit, and the like in the case of an analog system. In the case of a digital system, a digital tuner, an error correction unit, a demultiplexing unit, and the like are included.

  The external input unit 15 is an input interface including a plurality of external input terminals such as an RCA input terminal for inputting a composite signal and an S terminal for inputting an S signal. The external input unit 15 uses these external connection terminals to connect the television apparatus 1 to an external recording / reproducing apparatus such as a DVD player or an HDD recorder, and inputs an image signal and an audio signal.

  An A / D (Analog / Digital) converter 16 converts a signal input from the broadcast receiver 14 and the external input unit 15 into a digital signal when the signal is an analog signal such as a composite signal. If the input signal is a digital signal, no conversion is performed, and the input signal is output to the next signal separation unit 17 as it is.

  The signal separation unit 17 separates a digital signal including audio information and a digital signal including image information when the digital signal supplied from the A / D conversion unit 16 is encoded by the MPEG2 method or the like. Among these, a digital signal including audio information is sent to the D / A converter 18 to be converted into an analog signal, and is output from the speaker 20 by the audio signal output unit 19. At this time, the audio signal output unit 19 adjusts the output volume based on the instruction received from the control unit 11.

  The digital signal including the image information separated by the signal separation unit 17 is decoded by the image reproduction unit 21 and further converted into an NTSC image signal. The image signal obtained by the conversion is displayed on the display 23 by the image signal output unit 22. At this time, the image signal output unit 22 adjusts the image quality and brightness of the output image based on the instruction received from the control unit 11.

<1-2. About the configuration of the function section>

  Here, the relationship of each function part which comprises the volume adjustment function with which the television apparatus 1 which concerns on 1st embodiment of this invention is provided is demonstrated, using the functional block diagram of FIG.

  As shown in FIG. 1, the volume adjustment function of the present invention includes at least an image detection unit 11a (= image detection unit), a volume determination unit 11b (= volume determination unit), and a volume setting unit 11c (= volume setting) included in the control unit 11. A part of the means), an image designation unit 11d (= image designation unit), a memory 12, an operation unit 13, an audio signal output unit 19, and an image reproduction unit 21.

  The image detection unit 11a determines whether or not the image obtained by the image reproduction unit 21 matches an image output when the optical disk is ejected in the external recording / reproduction apparatus (hereinafter referred to as “image upon ejection”). The image at the time of ejection is, for example, a maker logo displayed when the optical disk drive is opened or closed, or a single color image such as a blue back image. Alternatively, when a discharge image is recorded in the memory 12 in advance by an image designating unit 11d described later, it is read and used. When an image that matches these images is detected, the image detection unit 11a instructs the next volume determination unit 11b to perform a volume determination process.

  When the above instruction is given, the sound volume determination unit 11b confirms the set value of the output sound volume when the sound signal output unit 19 outputs sound using the speaker 20. Then, it is determined whether or not the set value exceeds a predetermined value (= threshold value). As a result of the determination, if it is determined that the threshold value is exceeded, the next volume setting unit is instructed to perform the volume setting process.

  When the instruction is given, the volume setting unit 11c sets the output volume setting value to the audio signal output unit 19 to a predetermined value, for example, an intermediate value between the maximum value and the minimum value. However, the predetermined value needs to be in a range not exceeding the threshold value.

  The image designating unit 11d records the image designated by the user operation received by the operation unit 13 in the memory 12 as an ejection image output when the optical disc is ejected. The designation of the discharge image is performed, for example, by pressing the discharge image designation button included in the operation unit 13 in a state where the image that the user wants to designate as the discharge image is displayed on the display 23. The image designation unit 11d that has detected the pressing of the image designation button at the time of ejection acquires the image output from the image reproduction unit 21 at the time of detection of the depression, and records it in the memory 12 as an image at the time of ejection.

<1-3. Volume adjustment process>
Here, the volume adjustment processing by the television apparatus 1 according to the first embodiment of the present invention will be described with reference to the block diagrams of FIGS. 1 and 2 and the flowchart of FIG.

  FIG. 3 is a flowchart showing the processing flow of the volume adjustment processing according to the first embodiment of the present invention. This process shown in FIG. 3 is started when the control unit 11 detects that the television apparatus 1 is turned on. The power-on instruction is issued, for example, when a power activation button included in the operation unit 13 is pressed.

  After this processing is started, the control unit 11 determines whether or not an image signal is input by the external input unit 15 in step S110. As an image signal input from the external input unit 15, for example, an optical disk reproduction image signal output by a DVD player (not shown) is input. When the input of the image signal is not detected, the control unit 11 again moves to step S110 and monitors the input state.

  When the input of the image signal by the external input unit 15 is detected, the image detection unit 11a matches the maker logo image output when the optical disk is ejected in the DVD player or the like in step S120. Judge whether or not. The manufacturer logo image is recorded in advance in the memory 12 of the television device 1 at the time of factory shipment.

  When it is determined that the image matches the manufacturer logo image, the process proceeds to step S150 described later. Conversely, if it is determined that the image does not match the manufacturer logo image, in step S130, the image detection unit 11a determines whether the image obtained by the image reproduction unit 21 matches the single color image output after ejection from the optical disc in a DVD player or the like. Judge whether or not.

  When it is determined that the image matches the single color image, the process proceeds to step S150 described later. On the other hand, if it is determined that the image does not match the single color image, the image detection unit 11a reads from the memory 12 a discharge-time image that has been previously designated by the image designation unit 11d in step S140. Then, it is determined whether or not the image obtained by the image reproduction unit 21 matches the user-designated ejection image recorded in the memory 12.

  If it is determined that the image matches the user-specified ejection image, the process proceeds to step S150 described later. On the other hand, if it is determined that the image does not match the user-specified ejection image, the process proceeds to step S110 again, and the image input state is monitored by the external input unit 15.

  Next, in step S150, the volume determination unit 11b confirms the set value of the output volume of the audio signal output unit 19 set by the volume setting unit 11c. Then, it is determined whether or not the set value exceeds a predetermined value (= threshold). Specifically, for example, it is assumed that the output volume of the audio signal output unit 19 can be set to 20 levels of volume 0 to volume 19. If the threshold is set in advance for the volume 15, it is determined that the threshold is exceeded for volumes 16 to 19.

  If it is determined in step S150 that the set value does not exceed the threshold value, the process proceeds to step S110 again. Conversely, when it is determined that the threshold value is exceeded, the volume setting unit 11c sets the output volume of the audio signal output unit 19 to a predetermined value in step S160. For example, the intermediate volume 9 or the volume 10 is set among all the volumes. Thereafter, the process proceeds to step S110 again, and this process is continued.

  This process is normally terminated when the power of the television apparatus 1 is stopped. However, it may be configured such that the processing can be interrupted at an arbitrary timing by providing an instruction receiving unit that receives a processing interruption instruction.

<2-1. Internal configuration>
Here, the internal configuration of the television apparatus 1 according to the second embodiment of the present invention will be described with reference to the block diagram of FIG. In addition, about the component of the same content as Embodiment 1, description shall be abbreviate | omitted by adding the same code number.

  About the control part 11-the display 23, since it is the same content as Embodiment 1, description is abbreviate | omitted. The optical disk drive 24 (= optical disk reproducing means) optically reads information from an optical disk such as a CD medium or a DVD medium. The read data is sent to the signal separation unit 18 and separated into audio information and image information, and then reproduction processing is performed. Since there are a plurality of standards for optical disks, various processes (music playback, etc.) cannot be performed unless an optical disk conforming to the standards supported by the optical disk drive 24 is used.

<2-2. About the configuration of the function section>
Here, the relationship of each function part which comprises the volume adjustment function with which the television apparatus 1 which concerns on 2nd embodiment of this invention is provided is demonstrated, using the functional block diagram of FIG. In addition, about the component of the same content as Embodiment 1, description shall be abbreviate | omitted by adding the same code number.

  As shown in FIG. 4, the volume adjustment function of the present embodiment includes at least a volume determination unit 11b, a volume setting unit 11c, an optical disc detection unit 11e (= optical disc detection means), and an audio signal output unit 19 included in the control unit 11. And the optical disk drive 24.

  The optical disc detection unit 11e detects the ejection when the optical disc loaded in the optical disc drive 24 is ejected. And the notification which notifies that the optical disk was discharged is given to the volume determination part 11b. Receiving this notification, the volume determination unit 11b performs a volume adjustment process to be described later using the volume setting unit 11c and the audio signal output unit 19.

  As a specific method for detecting the ejection of the optical disk, for example, it is performed by monitoring the open / close state of a disk tray provided in the optical disk drive 24. Further, for example, the slot-in type optical disk drive 24 may be configured to monitor the generation of an optical disk ejection instruction.

<2-3. Volume adjustment process>
Here, the volume adjustment processing by the television apparatus 1 according to the second embodiment of the present invention will be described with reference to the block diagrams of FIGS. 4 and 5 and the flowchart of FIG.

  FIG. 6 is a flowchart showing a processing flow of volume adjustment processing according to the second embodiment of the present invention. This process shown in FIG. 6 is started when the control unit 11 detects that the television apparatus 1 is turned on. The power-on instruction is issued, for example, when a power activation button included in the operation unit 13 is pressed.

  After this process is started, the optical disc detection unit 11e determines whether ejection of the optical disc installed in the optical disc drive 24 is detected in step S210. If the ejection of the optical disk is not detected, the optical disk detection unit 11e moves again to step S210, and continues to detect the ejection of the optical disk.

  When the optical disk ejection is detected in step S210, the optical disk detection unit 11e notifies the volume determination unit 11b of the optical disk ejection detection. Receiving the notification, the sound volume determination unit 11b checks the set value of the output sound volume of the audio signal output unit 19 set by the sound volume setting unit 11c.

  In step S220, it is determined whether or not the set value of the output volume exceeds a predetermined value (= threshold). When it is determined that the set value does not exceed the threshold value, the process proceeds to step S210 again. Conversely, if it is determined that the threshold value is exceeded, the volume setting unit 11c sets the output volume of the audio signal output unit 19 to a predetermined value in step S230. For example, the volume 9 or the volume 10 that is close to the middle of all the volumes is set. Thereafter, the process proceeds to step S210 again, and this process is continued.

  This process is normally terminated when the power of the television apparatus 1 is stopped. However, the present embodiment may be configured such that the process can be interrupted at an arbitrary timing by providing an instruction receiving unit that receives a process interruption instruction.
