Abstract

PROBLEM TO BE SOLVED: To define the selected state of an operation item even if a reproducing signal is given by mistake when the operation item is in the selected state. SOLUTION: A DVD player outputs both of a definition signal and the reproducing signal when receiving a reproducing instruction whichever it is in a button selection mode or a normal selection mode (S5 to 7). Thus, even in a DVD where a reproduction key on a screen is defined by operating the enter key of a remote controller, the reproduction key on the screen can be defined to reproduce the picture of a main volume by operating the play key of a main body or the remote controller.

[0004] The DVD is stored in the disc storage tray B of the main body 130.
When set to 120, the main body 130 starts reading data from the DVD. Then, a menu image in which some buttons are displayed as shown in FIG. 6 is automatically displayed, and the apparatus enters the button selection mode. The menu image displays buttons B201, B203, and B205. Button B201 is a button for reproducing the main image, button B203 is a button for setting the language of audio and subtitles, and button B205 is a button for reproducing the introduction of the performer. is there.

[0005] The user operates the moving key B1 of the remote control 150.
By operating the button 90, a desired button is selected and the button is set to a selected state. At this time, the selected button is so-called highlighted. By operating the play key B150 in a state where the button is highlighted, the selection of the button is determined. As a result, in the main body 130, an image display process corresponding to the determined button is performed.

[0006]

The above-described DVD player 100 and DVD have the following problems.

[0007] The first problem is that after the user selects the "go to main story" button B201 of the menu image, the remote controller 1
This means that the main part may not be able to be reproduced even if the 50 play keys B150 are operated.

This is based on the following reasons. The DVD standard does not specify which key operation will determine the selected state when the button B201 in the menu image is in the selected state. Therefore, the button B20 in the menu image (see FIG. 6)
1 to determine the selection state of the button B201 by operating the play key B150 as described above, and to determine the selection state of the button B201 by operating the enter key B170.
D exists. 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.

The second problem is that the above-mentioned enter key B17
For a DVD for which the selection state of the button B201 is determined by operating 0, if the remote control 150 is not provided,
There is a problem that the button B201 cannot be determined and the main part cannot be reproduced.

[0010] This is because the remote controller 170 is usually provided with an enter key B170, but the main body 150 is often not provided with an enter key due to a problem such as an arrangement space.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an image reproducing apparatus which can determine a selected state of an operation item even when a reproduction signal is given by mistake when the operation item is in a selected state.

According to the first aspect of the present invention, the control unit outputs the determination signal even when a reproduction command is given with the operation item selected. Thus, even if a reproduction command is given when the operation item is in the selected state, a determination signal for determining the selected item can be output. Therefore, even if a reproduction command is given by mistake when the operation item is in the selected state, the selected state of the operation item can be determined. Further, even if it is not possible to give a determination command for determining the operation item, it is possible to determine the selected state of the operation item by providing a reproduction signal.

In the image reproducing apparatus according to a second aspect, when a reproduction command is given while the operation item is selected, the control unit outputs a decision signal for selecting the operation item, and When a decision command is given in the selected state, the reproduction signal is not output. Thereby, when the operation item is in the selected state, it is possible to output a determination signal for determining the selection item when a reproduction command is given, and not to output a reproduction signal when the determination command is given. Therefore, even if a malfunction occurs when the finalization signal and the reproduction signal are output by the finalization instruction, even if the reproduction instruction is given by mistake when the operation item is in the selected state, the selection state of the operation item is changed. Can be fixed.

According to a third aspect of the present invention, when a reproduction command is given while the image reproduction button is selected, the control unit outputs a reproduction signal and a decision signal.

Thus, in the button selection mode,
When the image playback button is in the selected state, the playback signal can be output even if the image playback operation of the confirmation signal and the playback signal is performed. Therefore, the user can obtain a desired image reproduction process regardless of whether the user inputs a selection decision command or a reproduction command in the button selection mode.

2. DVD Player A DVD which is an embodiment of the image reproducing apparatus 1 according to the present invention.
(Digital Versatile Disc) The player 21 will be described with reference to FIG.

2.1. Hardware Configuration The DVD player 21 has a main body 30 and a remote controller 60. FIG. 2 shows a hardware configuration of the main body 30.
The main body 30 includes a mechanical unit 51, a signal processing unit 52, a video / audio demodulation unit 53, an audio DAC 54, and a video DAC 5.
5, CPU 56, memory 57, operation unit 58, and SUB_CPU
59.

A mechanical unit 51 including a drive unit and a servo processing unit reads digital signals of the DVD 50. The signal processing unit 52 performs a synchronization detection process and the like on the digital signal read by the mechanical unit 51. The video / audio demodulator 53 performs an MPEG2 demodulation process 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 according to the DVD control program recorded in the memory 57. In addition, CPU
56 performs processing related to DVD playback.

The operation unit 58 receives an input operation from an operator. Also, a signal from remote controller 60 is received. The SUB_CPU 59 receives a signal from the operation unit and sends a predetermined signal to the CPU 56 according to the operation management program recorded in the memory 57. Note that SUB_CPU5
9 performs a signal transfer process between the operation unit 58 and the CPU 56.

2.2. Flowchart When the DVD 70 is set in the main body 30, a menu image as shown in FIG. 6 is displayed and the apparatus enters the button selection mode.
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 move key B190 on the remote controller 60 (see FIG. 5).
Is operated to highlight the button corresponding to the process to be performed from now on to bring it into the selected state. in this case,
It is assumed that the “to main part” button B201 is in a selected state in order to reproduce the main part. Since such processing is the same as in the related art, the description is omitted.

The SUB_CPU 59 determines whether a decision command has been received (S1: see FIG. 2). In the present embodiment, the signal from the enter key B 170 is used as the final signal. Therefore, it is determined whether or not the user has operated enter key B170 of remote controller 60.

When a decision command is received, the SUB_CPU
59 outputs a determination signal to the CPU 56 (S3). CPU5
The unit 6 controls each unit to execute the process of reproducing the main image when receiving the confirmation signal.

On the other hand, if the SUB_CPU 59 has not received the confirmation command, it determines whether a reproduction command has been received (S5). In the present embodiment, the play key B
The signal from 150 is a reproduction signal. Therefore,
It is determined whether or not the user has operated play key B150 of remote controller 150.

When a reproduction command is received, a reproduction signal and a decision signal are output to the CPU 56 (S7). CPU56
Executes the process of reproducing the main image when receiving the confirmation signal. Note that, in the button selection mode, the CPU 56 does not perform processing based on the reproduction signal even when receiving the reproduction signal, and thus the reproduction signal is ignored.

The processing of the SUB_CPU 59 in the case where the reproduction command is received in the button selection mode has been described so far. However, the SUB_CPU 59 performs the same processing in the normal reproduction mode. SU in other normal playback modes
The operation of the B_CPU 59 is almost the same as that of the conventional DVD player 100, and thus the description thereof is omitted.

As described above, in the DVD player 21, the CPU
Regardless of whether the button 56 is in the button selection mode or the normal playback mode, the SUB_CPU 59
00 (see FIG. 4), play key B150 of remote controller 60
(See FIG. 5)
At all times, both the decision signal and the reproduction signal are output. With such a configuration, the DV in which the button B201 is determined by the operation of the enter key B170
Even in the case of D, the button B201 can be determined by operating the play keys B100 and B150, and the image of the main part can be reproduced.

Further, the above-described configuration is achieved by using two CPUs (CPU 56 and SUB_CPU
59) is particularly effective. One of the CPUs (the SUB_CPU 59 in the present embodiment) always outputs both the decision signal and the reproduction signal when receiving the reproduction command, so that the state of the other CPU (the CPU 56 in the present embodiment) is output. Is in button selection mode or normal playback mode).
This is because a simpler program or hardware configuration can be used.

In the normal reproduction mode, the CPU 56
Since the processing for the final signal output from the UB_CPU 59 to the CPU 56 is not performed, after the main image is temporarily stopped,
Images can be reproduced.

[Other Embodiments] In the above-described embodiment, the main body 30 has a SUB_CP for processing an external signal.
It has a configuration including two U56s and a CPU 59 that controls each internal configuration. However, the body 30 integrates two functions
It may have only one CPU.

Further, in the above-described embodiment, the case where the image reproducing apparatus is the DVD player 21 has been described. However, the image reproducing apparatus has data relating to the menu image and data relating to the main image, and reproduces the data relating to the image. If it is, it is not limited to the example.

Further, the medium on which data relating to images is recorded may not be a DVD. As long as data relating to images can be recorded, magneto-optical disks such as video CDs, semiconductor recording media such as memories, floppy disks,
It may be a magnetic recording medium such as a hard disk.

Further, data relating to images need not be provided from a recording medium such as a DVD. For example,
Data regarding the image may be provided by communication (including wireless and wired).

Furthermore, in the above-described embodiment, the configuration is such that the enter command is input by the enter key B170 of the remote controller 60. However, the configuration is not limited to an example as long as the configuration is capable of inputting the enter command. For example, a configuration may be employed in which an enter key is provided on the main body 30 to input a confirmation command.

Furthermore, in the above-described embodiment, the operation of the enter key B170 is the button B201 in the selected state.
When the operation of the enter key B170 is given to the button B203 in the selected state, the operation of the enter key B170 is different from the operation of the enter key B170 when the operation of the enter key B170 is given to the button B203 in the selected state. Although the method of executing the operation of reproducing the main image is described even when the operation of the play key B150 is given to the button B201 in the selected state, the present invention is not limited to the exemplary operation.

That is, when the first operation input is given to the first operation item, a first operation predetermined for the first operation item is executed, and the first operation input is changed to the second operation item. When given to an item, in the method of performing an operation of performing a second operation predetermined for the second operation item, a second operation input different from the first operation input is a first operation input. Performing the first operation even if given to the item;
The method for executing the operation characterized by Thus, even when the second operation input is given to the first operation item, the first operation can be performed. Therefore, even if the first operation input and the second operation input are erroneously performed, the first operation can be performed.
