Description

  The present invention relates to an image disc playback / display apparatus and an image disc playback / display method.

  Conventionally, when a disc playback device and a display device of an image disc such as a VCD (Video Compact Disc), DVD (Digital Versatile Disk), DV (Digital Video), etc. are of an integrated type, the rotation of the disc is started.

<Embodiment 1>
Embodiment 1 of the present invention will be described below in detail with reference to the drawings. However, the scope of the invention is not limited to the illustrated example.

  FIG. 1 is a block diagram showing the main configuration of a monitor-equipped DVD player (hereinafter referred to as “DVD player”) as an image disc playback / display apparatus exemplified as a preferred embodiment to which the present invention is applied.

As shown in FIG. 1, a DVD player 1 according to the present embodiment includes a disc playback unit 2 as image playback means, a monitor 3 as display means for displaying images, a speaker 4 for outputting sound, and a CPU (Central Processing). Unit) 5, RAM (Random Access Memory) 6, R
OM (Read Only Memory) 7, etc. are provided.

  The disc playback unit 2 plays back and outputs image data stored on a DVD (disc). That is, the encoded digital image data and audio data are decoded to generate an image signal and an audio signal, the image signal is output to the monitor 3, and the audio signal is output to the speaker 4.

  Further, the disc reproducing unit 2 inputs a detecting unit 21 as a detecting means for detecting a predetermined operation from the start to the end of insertion into the disc reproducing unit 2, a tray 22 for carrying a disc, and an operation instruction for the tray 22. An operation unit 23 is provided for this purpose.

  For example, the detection unit 21 detects the end of the closing operation of the tray 22 as the predetermined operation. Specifically, detection is performed as follows.

  When the user instructs the opening operation of the tray 22 via the operation unit 23, the tray 22 starts the opening operation and extends from the disc reproducing unit 2 in the outward direction. When a DVD is placed on the tray 22 and a closing operation is instructed again via the operation unit 23, the tray 22 is returned to the inside of the disk reproducing unit 2, and the closing operation of the tray 22 is completed.

The end of the closing operation is recognized when the close line is changed from Low (L) to High (H) by pressing an analog switch provided on the tray 22 housed in the disc reproducing unit 2. That is, the detection unit 21 acquires detection information by detecting a change from L to H of the closed line. The acquired detection information is output to the CPU 5.

  The monitor 3 displays an image based on the image signal from the disc reproducing unit 2 as a display means, and the speaker 4 outputs an audio based on the audio signal from the disc reproducing unit 2.

  The CPU 5 controls each part of the DVD player 1 in an integrated manner, reads a predetermined program stored in the ROM 7, develops it in the work area of the RAM 6, and executes various processes according to the program. Specifically, the CPU 5 executes a predetermined control program and switches the image quality setting value of the monitor based on the detection information input via the disk reproducing unit 2.

  The RAM 6 forms a storage area 61 for temporarily storing programs, data, and the like, a work area 62 for executing the programs, and the like in each process executed by the CPU 5. The storage area 61 stores user setting values (described later) relating to the image quality setting values of the monitor 3 and functions as user setting value storage means.

  The ROM 7 stores various application software and programs necessary for executing the operation of the present invention. Specifically, for example, as shown in FIG. 1, a user setting value storage program 71, an image quality setting value switching program, and the like. 72, a switching determination program 73, a user setting value switching program 74, an initial setting value data table 75, and the like are stored.

  The user setting value storage program 71 is a program for storing user setting values relating to the image quality of the image displayed on the monitor 3 that are arbitrarily set by the user. The CPU 5 stores the user setting value storage program 71 in the user setting value storage program 71. By executing it, it functions as a part of the user setting value storage means.

  Here, user setting values will be described. The image quality setting value of the image displayed on the monitor 3 can be changed (adjusted) from the initial setting value to any setting desired by the user. Examples of changeable image quality setting value items include brightness (BRT), video (CNT), color (COL), hue (TINT), sharpness (SHARPNESS), and the like. The desired image quality of the user can be realized by changing.

  As described above, the user setting value arbitrarily set according to the user's preference is stored by the CPU 5 in the RAM 6 that functions as a user setting value storage unit together with the CPU 5.

  On the other hand, the initial setting value is an image quality setting value set in advance for the image on the monitor 3, and is the most standard setting in a state where none of BRT, CNT, COL, TINT, SHARPESS, etc. is defaulted. . The initial set values are stored in an initial set value data table 75 of the ROM 7 as an initial set value storage means.

  The image quality setting value switching program 72 sets the image quality setting value of the image displayed on the monitor 3 from the user setting value arbitrarily set by the user when the detection unit 21 detects the end of the disc closing operation. A program for switching to the initial setting values in the setting value data table 75, and the CPU 5 functions as image quality setting value switching means by executing the image quality setting value switching program 72.

  Specifically, when the closing line of the tray 22 included in the disc reproducing unit 2 changes to H, the detection unit 21 detects the end of the closing operation, and the acquired detection information is output to the CPU 5, the CPU 5 The image setting value switching is executed by executing the image setting value switching program 72.

  The switching determination program 73 is a program for determining whether or not a predetermined condition for switching the image quality setting value switched to the initial setting value to the user setting value by the CPU 5 as the image quality setting value switching means is satisfied. The CPU 5 functions as a switching determination unit by executing the switching determination program 73.

  Here, the “predetermined condition” means, for example, that a predetermined time has elapsed since the detection information was input to the CPU 5 by the detection unit 21. In the present embodiment, the detection information is The predetermined condition is that 5 seconds have elapsed since the input to the CPU 5.

  The user setting value switching program 74 sets the image quality setting value in the monitor 3 from the initial setting value when the CPU 5 as the switching determination means determines that 5 seconds have elapsed since the detection information described above was input to the CPU 5. The CPU 5 is a program for switching to user setting values stored in the RAM 6, and the CPU 5 functions as user setting value switching means by executing the user setting value switching program 74.

  The DVD player 1 is configured as described above, and the power supplied to the disc playback unit 2, the monitor 3, the speaker 4, the CPU 5, the RAM 6, and the ROM 7 is supplied from the same power source (not shown).

  Next, image quality setting value switching processing in the DVD player 1 will be described using the flowchart shown in FIG.

  First, the DVD player 1 is turned on and started up (step S1). Then, CPU5 judges the presence or absence of detection information (step S2). When a DVD is inserted into the disc playback unit 2 via the tray 22 and detection information detected by the detection unit 21 based on a change in the closed line (from L to H) is output to the CPU 5 (step S2; Yes) The CPU 5 determines whether or not the image quality setting value of the image displayed on the monitor 3 has been changed by the user by executing a control program (not shown) (step S3). When the image quality setting value is changed by the user, that is, when it is the user setting value (step S3; Yes), the CPU 5 stores the user setting value in the RAM 6 by executing the user setting value storage program 71 ( Step S4; user setting value storing step). When no detection information is output to the CPU 5 (step S2; No), the CPU 5 enters a standby state.

  When the user setting values are stored in the RAM 6, the CPU 5 executes the image quality setting value switching program 72 to call up the initial setting values from the initial setting value data table 75, and the image quality setting values of the image displayed on the monitor 3. Are switched from the user setting value to the initial setting value (step S5; image quality setting value switching step).

  In step S6, the CPU 5 executes the switching determination program 73 to determine whether or not 5 seconds have elapsed since the detection information detected by the detection unit 21 is output to the CPU 5 (step S6; switching). Judgment process). When the CPU 5 determines that 5 seconds have elapsed (step S6; Yes), the CPU 5 executes the user setting value switching program 74 to thereby change the image quality setting value of the image displayed on the monitor 3 in the initial state that is switched in step S5. The setting value is switched to the user setting value stored in the RAM 6 (step S7; user setting value switching step), and the image quality setting value switching process is terminated.

  In step S6, if the CPU 5 determines that 5 seconds have not elapsed (step S6; No), the image quality setting value is not switched, and again a predetermined condition (5 seconds have elapsed after the detection information is output to the CPU 5). Whether or not it is established is determined.

  In step S3, if the CPU 5 determines that the image quality setting value of the monitor 3 remains the initial setting value (step S3; No), the image quality setting value switching process ends without performing any process.

  According to the DVD player 1 according to the first embodiment described above, the rotation of the DVD starts after the image quality setting value of the monitor 3 is switched from the user setting value to the initial setting value. As a result, the power supplied to the monitor 3 decreases due to the increase in power consumption in the disc playback unit 2 that occurs when the DVD starts rotating, that is, when the motor is driven, and even if noise occurs in the monitor 3, the noise is reduced. It can be easily and inconspicuous. Further, since it is realized only by switching the image quality setting value of the monitor 3, noise can be made inconspicuous without cost.

  Furthermore, since the image quality setting value of the monitor 3 that has been switched to the initial setting value is switched to the user setting value again after 5 seconds from the detection information output, noise can be reduced without impairing the user's comfortable use environment. Can be realized.

  The instruction for the disc closing operation may be input, for example, by lightly pushing the tray 22 in the direction of the disc reproducing unit 2 without using the operation unit 23, or the disc reproducing unit 2 may close the tray 22. It may be automatically input after a predetermined time has elapsed since the end was detected. Similarly, the disk opening operation may be input without going through the operation unit 23.

Further, the predetermined condition in the switching determination step is not limited to the elapse of 5 seconds after the detection information is output to the CPU 5, and may be, for example, a condition that a certain time elapses after the start of the motor is started. However, the disc may be recognized by a disc recognition unit (not shown), and it is preferable that the conditions are such that a comfortable use environment for the user can be provided.
<Embodiment 2>
The DVD player 100 according to the second embodiment will be described below. The DVD player 100 is different from the DVD player 1 according to the first embodiment in the program stored in the ROM 107. Therefore, in the description of the second embodiment, the same components as those of the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  As shown in FIG. 3, the ROM 107 in the DVD player 100 according to the second embodiment stores an image quality setting value switching program 172 instead of the image quality setting value switching program 72 in the ROM 7 according to the first embodiment. In addition, a threshold data table 176 is stored.

  The image quality setting value switching program 172 is a case where the end of the closing operation of the tray 22 is detected by the detection unit 21, and the user setting value arbitrarily set by the user deviates from the preset threshold value 176. In this case, the CPU 5 functions as an image quality setting value switching unit by executing the image quality setting value switching program 172.

  In the threshold data table 176, each item that determines the image quality of an image is associated with a threshold value in each item. Specifically, for example, BRT, CNT, COL, TINT, SHARPESS, and the like as items for determining image quality are associated with threshold values of the respective items.

  The threshold means a limit value in an image quality setting value range that can realize an image quality in which noise generated on a monitor is not conspicuous when a DVD is inserted. For example, when BRT is taken as an example, a BRT level of a user setting value is an initial setting. If noise is conspicuous when the value deviates 30 or more from the BRT level, the BRT threshold is set to “30”. Here, the threshold value is not limited to 30, and may be set to “40”, for example, over a wider range, or any set value within a range where image quality in which noise generation is not noticeable can be suitably realized. can do.

  Similarly, for other items other than BRT, a limit value (threshold value) in a set value range capable of realizing an image quality where noise generation is not noticeable is determined.

  The image quality setting value may be switched when any one of the items exceeds the threshold value, or may be switched when all the items exceed the threshold value. This item may be limited in advance.

  Hereinafter, the image quality setting value switching processing by the DVD player 100 will be described with reference to the flowchart shown in FIG.

First, the DVD player 1 is turned on and started up (step S101). Then, the CPU 5 determines whether there is detection information (step S102). When a DVD is inserted into the disc playback unit 2 via the tray 22 and detection information detected by the detection unit 21 based on a change in the closed line (from L to H) is output to the CPU 5 (step S102; Yes). The CPU 5 determines whether or not the image quality setting value of the image displayed on the monitor 3 has been changed by the user by executing a control program (not shown) (step S103). When the image quality setting value is changed by the user, that is, when it is the user setting value (step S103; Yes), the CPU 5 stores the user setting value in the RAM 6 by executing the user setting value storage program 71 ( Step S104; user setting value storing step). When no detection information is output to the CPU 5 (step S102; No)
), The CPU 5 enters a standby state.

  Next, the CPU 5 calls the threshold value of the threshold value data table 176 and the user setting value stored in the RAM 6 and executes the image quality setting value switching program 172 to determine whether or not the user setting value is out of the threshold value. (Step S105; image quality setting value switching step). If the CPU 5 determines that the user setting value is out of the threshold (step S105; Yes), the image quality setting value of the monitor 3 is switched from the user setting value to the initial setting value as in the first embodiment (step S106; Image quality setting value switching step).

  In step S107, the CPU 5 executes the switching determination program 73 to determine whether or not five seconds have elapsed since the detection information detected by the detection unit 21 is output to the CPU 5 (step S107; switching). Judgment process). When the CPU 5 determines that 5 seconds have elapsed (step S107; Yes), the CPU 5 executes the user setting value switching program 74, whereby the image quality setting value of the image displayed on the monitor 3 is switched in the initial step S106. The setting value is switched to the user setting value stored in the RAM 6 (step S108; user setting value switching step), and the image quality setting value switching process is terminated.

  If the CPU 5 determines that 5 seconds have not elapsed (step S107; No), the image quality setting value is not switched, and whether or not a predetermined condition (5 seconds have elapsed after the detection information is output to the CPU 5) is satisfied. To be judged.

  When the image quality setting value of the monitor 3 is not the user setting value (step S103; No) and when the user setting value does not deviate from the threshold value (step S105; No), the image quality setting value is switched at that time. The process ends.

  According to the DVD player 100 according to the second embodiment described above, after the image quality setting value of the monitor 3 is switched from the user setting value having a value deviating from the preset threshold value 176 to the initial setting value, the rotation of the DVD is performed. Will start.

  As a result, the power supplied to the monitor 3 decreases due to the increase in power consumption in the disc playback unit 2 that occurs when the DVD starts rotating, that is, when the motor is driven, and even if noise occurs in the monitor 3, the noise is reduced. It can be easily and inconspicuous.

  Further, since it is realized only by switching the image quality setting value of the monitor 3, noise can be made inconspicuous without cost.

Furthermore, the image quality setting value of the monitor 3 switched to the initial setting value is switched to the user setting value again after 5 seconds from the detection information being input to the CPU 5, thereby impairing the comfortable use environment for the user. Therefore, noise can be reduced.
<Embodiment 3>
The DVD player 200 according to Embodiment 3 will be described below. The DVD player 200 is different from the DVD player 1 according to the first embodiment in the program stored in the ROM 207. Therefore, in describing the third embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in FIG. 5, the ROM 207 in the DVD player 200 according to the third embodiment stores an image quality setting value switching program 272 in place of the image quality setting value switching program 72 in the ROM 7 according to the first embodiment. Instead of the switching program 74, a user setting value switching program 274 is stored. Further, the initial set value data table 75 in the ROM 7 is not stored, while the threshold data table 176 stored in the ROM 107 according to the second embodiment is stored.

The image quality setting value switching program 272 is used to switch from the user setting value to the threshold value when the detection unit 21 detects the end of the closing operation and the user setting value deviates from the preset threshold value. The CPU 5 functions as image quality setting value switching means by executing the image quality setting value switching program 272. The user setting value switching program 274 switches the image quality setting value on the monitor 3 from the threshold value to the user setting value when the CPU 5 determines that 5 seconds have elapsed since the detection information is output to the CPU 5. The CPU 5 functions as user setting value switching means by executing the user setting value switching program 274.

  Hereinafter, the image quality setting value switching processing by the DVD player 200 will be described with reference to the flowchart shown in FIG.

  First, the DVD player 1 is turned on and started up (step S201). Then, the CPU 5 determines whether or not detection information is input (step S202). When a DVD is inserted into the disc playback unit 2 via the tray 22 and detection information detected by the detection unit 21 based on a change in the closed line (from L to H) is output to the CPU 5 (step S202; Yes). The CPU 5 determines whether or not the image quality setting value of the image displayed on the monitor 3 has been changed by the user by executing a startup program (not shown) (step S203). If it is a user set value (step S203; Yes), the CPU 5 stores the user set value in the RAM 6 by executing the user set value storage program 71 (step S204; user set value storage step). When no detection information is input to the CPU 5 (step S202; No), the CPU 5 enters a standby state.

  Next, the CPU 5 calls the user setting values stored in the threshold data table 176 and the RAM 6 and executes the image quality setting value switching program 272 to determine whether or not the value of the user setting value is out of the threshold value ( Step S205: Image quality setting value switching step). If the CPU 5 determines that it is outside the threshold (step S205; Yes), it switches the image quality setting value of the monitor 3 from the user setting value to the threshold (step S206; image quality setting value switching step).

  In step S207, the CPU 5 executes the switching determination program 73 to determine whether or not 5 seconds have elapsed since the detection information detected by the detection unit 21 is output to the CPU 5 (step S207; switching). Judgment process). When the CPU 5 determines that 5 seconds have elapsed (step S207; Yes), the CPU 5 executes the user setting value switching program 274 to change the image quality setting value of the image displayed on the monitor 3 to the threshold value switched in step S206. From the user setting value stored in the RAM 6 (step S208; user setting value switching step), and the image quality setting value switching process is terminated.

  If the CPU 5 determines that 5 seconds have not elapsed (step S207; No), the image quality setting value is not switched, and whether or not a predetermined condition (5 seconds have elapsed after the detection information is output to the CPU 5) is satisfied. To be judged.

  When the image quality setting value of the monitor 3 is not the user setting value (step S203; No) and when the user setting value does not deviate from the threshold value (step S205; No), the image quality setting value is switched at that time. The process ends.

According to the DVD player 200 in the third embodiment described above, the rotation of the DVD is performed after the image quality setting value of the monitor 3 is switched from the user setting value having a value deviating from the preset threshold value 176 to the initial setting value. Will start.

  As a result, the power supplied to the monitor 3 decreases due to the increase in power consumption in the disc playback unit 2 that occurs when the DVD starts rotating, that is, when the motor is driven, and even if noise occurs in the monitor 3, the noise is reduced. It can be easily and inconspicuous.

  Further, since it is realized only by switching the image quality setting value of the monitor 3, noise can be made inconspicuous without cost.

Furthermore, the image quality setting value of the monitor 3 switched to the threshold setting is switched to the user setting value again after a predetermined condition is satisfied.

  As a result, the image quality setting value of the monitor 3 is switched again to the image quality setting value desired by the user, and noise can be reduced without impairing the use environment comfortable for the user.

  Then, since switching from the user setting value to the setting at the threshold value is stopped, a change in image quality due to the switching of the image quality setting value can be suppressed to a minimum, and the uncomfortable feeling given to the user can be reduced.
