Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an image reproducing apparatus, and more particularly to an image reproducing apparatus that can appropriately perform an image display process even with respect to a user's erroneous operation input.
[0002]
[Prior art]
A DVD player 100 that plays back a DVD (Digital Versatile Disc) as a conventional image playback device will be described with reference to FIGS. The DVD player 100 has a main body 130 and a remote controller 150.
[0003]
FIG. 4 shows an external view of the main body 130. The main body 130 has a playback button B100 on the front surface of the panel. FIG. 5 shows an external view of the remote controller 150. The remote controller 150 has a reproduction key B150, an enter key B170, and a movement key B190 on the operation surface.
[0004]
When the DVD is set in the disc storage tray B120 of the main body 130, the main body 130 starts reading data from the DVD. Then, a menu image on which some buttons as shown in FIG. 6 are displayed is automatically displayed and the button selection mode is entered. Button B201, button B203, and button B205 are displayed on the menu image. The button B201 is a button for reproducing the main image, the button B203 is a button for setting the language of audio and subtitles, and the button B205 is a button for reproducing the introduction of the performer. is there.
[0005]
The user operates the movement key B190 of the remote controller 150, selects a desired button, and puts the button in a selected state. At this time, the selected button is so-called highlighted. While the button is highlighted, the selection of the button is confirmed by operating the play key B150. As a result, image display processing corresponding to the confirmed button is performed in the main body 130.
[0006]
[Problems to be solved by the invention]
The aforementioned DVD player 100 and DVD have the following problems.
[0007]
The first problem is that the user may not be able to reproduce the main part even if the user operates the play key B150 of the remote controller 150 after selecting the “go to main part” button B201 of the menu image. is there.
[0008]
This is due to the following reason. According to the DVD standard, it is not stipulated which key operation to confirm the selection state when the button B201 in the menu image is in the selection state. Therefore, when the button B201 is confirmed in the menu image (see FIG. 6) and the image is reproduced, the selection of the button B201 is confirmed by operating the play key B150 as described above, and the enter key B170 is operated. Thus, there is a DVD or the like that determines the selection state of the button B201. Therefore, in the case of the latter DVD, even if the user operates the play key B150 of the remote controller 150 after selecting the “go to main part” button B201 of the menu image, the main part cannot be reproduced.
[0009]
The second problem is that for a DVD that determines the selected state of the button B201 by operating the enter key B170, the button B201 cannot be determined without the remote controller 150, and the main part is reproduced. There is a problem that can not be.
[0010]
This is because the remote controller 170 is usually provided with the enter key B170, but the main body 150 is often not provided with the enter key due to problems such as the arrangement space.
[0011]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an image reproduction apparatus that can determine the selection state of an operation item even if a reproduction signal is erroneously given when the operation item is in a selection state.
[0012]
It is another object of the present invention to provide an image reproducing apparatus that can determine the selection state of an operation item by providing a reproduction signal even if a confirmation signal for determining the operation item cannot be provided.
[0013]
It is another object of the present invention to provide an image reproduction apparatus capable of obtaining a desired image reproduction process regardless of whether a confirmation command or a reproduction command is input in the button selection mode.
[0014]
[Means for Solving the Problems and Effects of the Invention]
In the image reproducing apparatus according to the present invention, the control unit, when the operation item reproduction command to execute an image playback process is given in selected state, it outputs the reproduction signal to execute the determination signal and the image reproduction processing To do. Thereby, even if a reproduction command is given when the operation item is in the selected state, a confirmation signal for confirming the selected item can be output. Therefore, even if an operation item is in a selected state and a reproduction command is given by mistake, the selected state of the operation item can be confirmed. Even if a confirmation command for confirming the operation item cannot be given, the selection state of the operation item can be confirmed by providing a reproduction signal.
[0016]
In the DVD player according to the present invention , the control unit outputs a confirmation signal and a playback signal for executing the image playback process when a playback command is given when the image playback button is in the selected state in the button selection mode. .
[0017]
Thus, in the button selection mode, when the image reproduction button is in the selected state, the reproduction signal can be output even if the image reproduction operation of the confirmation signal and the reproduction signal is performed. Therefore, the user can obtain a desired image reproduction process regardless of whether the selection determination instruction or the reproduction instruction is input in the button selection mode.
[0018]
Here, the correspondence between each constituent element of the claim and each constituent element of the embodiment is shown. The operation item display signal output unit corresponds to the mechanical unit 51, the signal processing unit 52, the video / audio demodulation unit 53, the video DAC 55 and the CPU 56, the operation input unit corresponds to the operation unit 58 and the remote controller 60, and the control unit corresponds to the SUB_CPU 59. Also, the button display signal output unit is the mechanical unit 51, the signal processing unit 52, the video / audio demodulation unit 53, the video DAC 55 and the CPU 56, the confirmation command input unit is the remote control 60, the playback command input unit is the operation unit 58 and the remote control 60. Respectively.
[0019]
Further, the control unit executes each step shown in the flowchart of FIG.
[0020]
DETAILED DESCRIPTION OF THE INVENTION
1. Overall Configuration of Image Playback Device FIG. 1 shows the overall configuration of an embodiment of an image playback device 1 according to the present invention. The operation item display signal output unit 3 includes an operation input unit 5 and a control unit 7.
[0021]
The operation item display signal output unit 3 outputs an operation item display signal for displaying an operation item in a selected state or a non-selected state. The operation input unit 5 receives a confirmation command for confirming the selection state of the operation item.
[0022]
When a confirmation command is given with the operation item selected, the control unit 7 outputs a confirmation signal for confirming the selection of the operation item. A confirmation signal is also output when a reproduction command is given with the operation item selected. Further, when a playback command is given when the operation item is selected, a confirmation signal for selecting the operation item is output. When a confirmation command is given when the operation item is selected, a playback signal is output. Do not output.
[0023]
Thus, even when an operation item is in a selected state, even if a reproduction command is erroneously given, the selected state of the operation item can be confirmed.
[0024]
Even if a confirmation command for confirming the operation item cannot be given, the selection state of the operation item can be confirmed by giving a reproduction command.
[0025]
Furthermore, even if a confirmation signal and a playback signal are output in response to a confirmation command, a malfunction may occur. Can be determined.
[0026]
Further, the user can obtain a desired image reproduction process regardless of whether the confirmation command or the reproduction command is input in the button selection mode.
[0027]
2. DVD Player A DVD (Digital Versatile Disc) player 21 which is an embodiment of the image reproducing apparatus 1 according to the present invention will be described with reference to FIG.
[0028]
2.1. Hardware configuration
The DVD player 21 has a main body 30 and a remote controller 60. The hardware configuration of the main body 30 is shown in FIG. The main body 30 includes a mechanical unit 51, a signal processing unit 52, a video / audio demodulation unit 53, an audio DAC 54, a video DAC 55, a CPU 56, a memory 57, an operation unit 58, and a SUB_CPU 59.
[0029]
A mechanical unit 51 including a drive unit and a servo processing unit reads a digital signal of the DVD 50. The signal processing unit 52 performs a synchronization detection process on the digital signal read by the mechanical unit 51. The video / audio demodulator 53 performs MPEG2 demodulation processing on the digital signal. The audio DAC 54 converts the demodulated digital audio signal into an analog audio signal. The video DAC 55 converts the demodulated digital video signal into an analog video signal. The display unit 50 displays an image based on the analog video signal. The CPU 56 controls the operation of each unit in accordance with the DVD control program recorded in the memory 57. The CPU 56 performs processing related to DVD playback.
[0030]
The operation unit 58 receives an input operation from the operator. Further, a signal from the remote controller 60 is received. The SUB_CPU 59 receives a signal from the operation unit according to the operation management program recorded in the memory 57 and sends a predetermined signal to the CPU 56. The SUB_CPU 59 performs signal transfer processing between the operation unit 58 and the CPU 56.
[0031]
2.2. When the DVD 70 is set in the flowchart body 30, a menu image as shown in FIG. 6 is displayed and the button selection mode is entered. An example of the control operation of the SUB_CPU 59 in the button selection mode will be described with reference to the flowchart shown in FIG. The user operates the movement key B190 (see FIG. 5) of the remote controller 60, highlights the button corresponding to the process to be performed, and sets the selected state. In this case, it is assumed that the “to main part” button B201 is selected to reproduce the main part. Since this process is the same as the conventional process, the description thereof is omitted.
[0032]
The SUB_CPU 59 determines whether or not a confirmation command has been received (S1: see FIG. 2). In the present embodiment, the signal from the enter key B170 is used as the confirmation signal. Therefore, it is determined whether or not the user has operated enter key B170 of remote controller 60.
[0033]
When the confirmation command is received, the SUB_CPU 59 outputs a confirmation signal to the CPU 56 (S3). When the CPU 56 receives the confirmation signal, the CPU 56 controls each unit to execute processing for reproducing the main image.
[0034]
On the other hand, if the SUB_CPU 59 does not receive a confirmation command, it determines whether or not a playback command has been received (S5). In the present embodiment, a signal from the play key B150 is used as a reproduction signal. Therefore, it is determined whether or not the user has operated play key B150 of remote controller 150.
[0035]
If a reproduction command is received, a reproduction signal and a confirmation signal are output to the CPU 56 (S7). When the CPU 56 receives the confirmation signal, it executes a process of reproducing the main image. In the button selection mode, the CPU 56 ignores the reproduction signal because it does not perform processing based on the reproduction signal even if it receives the reproduction signal.
[0036]
Up to now, the processing of the SUB_CPU 59 when a playback command is received in the button selection mode has been described, but the SUB_CPU 59 performs the same processing in the normal playback mode. Since the operation of the SUB_CPU 59 in other normal playback modes is almost the same as that of the conventional DVD player 100, the description thereof is omitted.
[0037]
As described above, in the DVD player 21, regardless of whether the CPU 56 is in the button selection mode or the normal playback mode, the SUB_CPU 59 plays the play key B100 (see FIG. 4) of the main body 30 and the play key B150 (see FIG. 4) of the remote controller 60. When the reproduction command by the operation of (5) is received, both the confirmation signal and the reproduction signal are always output. With this configuration, even if the button B201 is determined by operating the enter key B170, the button B201 can be determined by operating the play keys B100 and B150, and the main image is reproduced. be able to.
[0038]
Furthermore, the above-described configuration is particularly effective when two CPUs (CPU 56 and SUB_CPU 59) as shown in the present embodiment are provided. That is, when one CPU (SUB_CPU 59 in this embodiment) receives a reproduction command, it always outputs both a confirmation signal and a reproduction signal, so that the state of the other CPU (CPU 56 in this embodiment) is output. This is because it is not necessary to determine whether the button is in the button selection mode or the normal playback mode, and a simpler program or hardware configuration can be achieved.
[0039]
Further, in the normal playback mode, the CPU 56 does not perform processing on the confirmation signal output from the SUB_CPU 59 to the CPU 56, so that the image can be played after the main image is paused.
[0040]
[Other Embodiments]
In the above-described embodiment, the main body 30 has a configuration including the SUB_CPU 56 that processes an external signal and the CPU 59 that controls each internal configuration. However, the main body 30 may have only one CPU that integrates two functions.
[0041]
In the above-described embodiment, the case where the image reproducing device is the DVD player 21 is shown. However, any image reproducing device that has data relating to the menu image and data relating to the main image and reproduces data relating to the image. However, the present invention is not limited to the examples.
[0042]
Furthermore, the medium on which the data regarding the image is recorded may not be a DVD. As long as data relating to images can be recorded, it may be a magneto-optical disk such as a video CD, a semiconductor recording medium such as a memory, a magnetic recording medium such as a floppy disk or a hard disk.
[0043]
Furthermore, the data relating to the image need not be provided from a recording medium such as a DVD. For example, data regarding an image may be provided by communication (including wireless and wired).
[0044]
Furthermore, in the above-described embodiment, the confirmation command is input by the enter key B170 of the remote controller 60. However, the configuration is not limited to the example as long as the confirmation command can be input. For example, an enter key may be provided in the main body 30 to input a confirmation command.
[0045]
Furthermore, in the above-described embodiment, when the operation of the enter key B170 is given to the button B201 in the selected state, the main image is played back, and when the operation of the enter key B170 is given to the button B203 in the selected state, the language The operation execution method for executing reproduction of the main image even when the operation of the play key B150 different from the operation of the enter key B170 is given to the selected button B201. Although shown, it is not limited to performing the example operations.
[0046]
That is, when the first operation input is given to the first operation item, the first operation predetermined for the first operation item is executed, and the first operation input is given to the second operation item. Then, in the operation execution method for executing the second operation predetermined for the second operation item, a second operation input different from the first operation input is given to the first operation item. Alternatively, the operation may be performed by performing the first operation. Thereby, even when the second operation input is given to the first operation item, the first operation can be executed. Therefore, even if the first operation input and the second operation input are erroneously performed, the first operation can be executed.
