  However, the conventional television broadcast receiver has the following problems. That is, in this television broadcast receiver, it is necessary to set in advance the program conditions for restricting viewing by inputting various setting values from many setting screens. For this reason, there are problems that the setting operation is complicated and that setting takes a long time. On the other hand, among programs that do not meet the above conditions (time zone or channel), there may be programs that are inappropriate for children to watch. When such a program is broadcast while the family is watching TV, it is necessary to newly add a condition for restricting the viewing of the program. As described above, the setting operation for restricting the viewing is required. Is complicated and takes a long time. For this reason, in such a case, generally, a method of avoiding inappropriate viewing of a program by a child by switching the channel to another channel is generally adopted. However, with this method, it is possible to view the program by simply switching the channel to the original channel by mistake, and it is difficult to reliably avoid viewing an inappropriate program by a child.

  The present invention has been made in view of such problems, and a receiving apparatus and a television that can easily and quickly set viewing restrictions on a program being broadcast and select channels that are broadcasting the program. The main purpose is to provide

  In order to achieve the above object, a receiving apparatus according to the present invention includes a receiving unit that receives a broadcast signal, and a control unit that controls switching of a channel of the broadcast signal that is received by the receiving unit. When a predetermined operation is performed after the channel is switched, a viewing restriction setting process is executed for setting a program broadcast on the channel selected immediately before the channel switching as a target of viewing restriction.

  According to this receiving apparatus, when a predetermined operation is performed after the channel is switched, the control unit executes the viewing restriction setting process, so that the broadcast is broadcast on the channel immediately before the channel switching only by performing the predetermined operation. The program that has been viewed can be set as a viewing restriction target. For this reason, compared with the configuration in which various setting values are input from the setting screen, a complicated operation for inputting a condition for specifying a program can be eliminated. Viewing restriction can be set. Therefore, for example, even when an inappropriate program starts to be broadcast to a child while watching a program with a family member, the inappropriate program by the child can be performed only by switching the channel and performing a predetermined operation. Can be surely avoided.

  In the receiving device according to the present invention, in the receiving device, the control unit executes the viewing restriction setting process when a predetermined operation key is operated as the predetermined operation.

  According to this receiving apparatus, when a predetermined operation key is operated, the control unit executes the viewing restriction setting process, thereby setting the viewing restriction target in one operation (one action) for operating the operation key. Therefore, the viewing restriction can be set more easily in a shorter time.

  In the receiving apparatus according to the present invention, in the above receiving apparatus, the control unit is assigned a rating level equal to or higher than a rating level given to the program broadcast immediately before in the viewing restriction setting process. The program is set as the viewing restriction target.

According to this receiving apparatus, the control unit sets a program to which a rating level equal to or higher than the rating level assigned to the program broadcast immediately before the channel switching is set as a viewing restriction target, for example, These programs can be set as viewing restriction targets quickly and easily without individually setting other programs that are considered inappropriate for children.

  The receiving apparatus according to the present invention includes a receiving unit that receives a broadcast signal, and a control unit that controls switching of a channel of the broadcast signal received by the receiving unit, and the control unit switches the channel. When a predetermined operation is performed later, a selection restriction setting process for setting a channel selected immediately before the channel switching as a target of selection restriction is executed.

  According to this receiving apparatus, when a predetermined operation is performed after the channel is switched, the control unit executes the selection restriction setting process so that the channel immediately before the channel switching can be obtained only by performing the predetermined operation. It can be set as a selection restriction target in which selection itself is restricted. For this reason, for example, compared with a configuration in which various setting values are input from the setting screen, it is possible to eliminate a complicated operation of inputting a condition for specifying a channel. It is possible to easily set selection restrictions. Therefore, for example, even when an inappropriate program starts to be broadcast to a child while watching the program with a family member, the child can only view the inappropriate program by switching the channel and performing a predetermined operation. Viewing can be reliably avoided.

  In the receiving device according to the present invention, in the above receiving device, the control unit executes the selection restriction setting process when a predetermined operation key is operated as the predetermined operation.

  According to this receiving apparatus, when a predetermined operation key is operated, the control unit executes selection restriction setting processing, thereby setting a viewing restriction target in one operation (one action) for operating the operation key. Therefore, the viewing restriction can be set more easily in a shorter time.

  Further, the receiving device according to the present invention is the above receiving device, wherein the control unit skips the selection-restricted channel with respect to the receiving unit when a channel up key or a channel down key is operated. To receive broadcast signals from other channels.

  According to this receiving apparatus, when the channel up key or the channel down key is operated, the control unit skips the channel subject to selection restriction and receives broadcast signals of other channels. Even if an attempt is made to select a set channel, it is possible to automatically select another channel that can be selected by skipping that channel. For this reason, for example, when a channel set as a selection restriction target is selected, a non-display state or a message indicating that the selection restriction target is displayed is displayed. The operability can be improved as compared with the configuration in which another channel that can be selected by requesting the operation is selected.

  The television according to the present invention includes the above-described receiving device and a display unit that displays an image based on the broadcast signal received by the receiving device.

  According to this television, by providing the above receiving device, it is possible to realize the same effect as the above receiving device.

  The best mode of a receiving apparatus and a television according to the present invention will be described below with reference to the accompanying drawings. A projection television (hereinafter also simply referred to as “TV”) 1 shown in FIG. 1 is an example of a television according to the present invention, and includes a main body 2 and a remote controller 3 as shown in FIG. . The main unit 2 includes a channel selection processing unit 11, a tuner 12, a preset information storage unit 13, a video / audio processing unit 14, a video output unit 15, a display unit 16, an audio output unit 17, a speaker 18, a channel selection / program information storage unit. 19, a restriction information storage unit 20, a personal identification number storage unit 21, a light receiving unit 22, a key input processing unit 23, and a control unit 24. In this case, the channel selection processing unit 11, the tuner 12, the preset information storage unit 13, the video / audio processing unit 14, the channel selection / program information storage unit 19, the restriction information storage unit 20, the code number storage unit 21, the light receiving unit 22, the key The input processing unit 23 and the control unit 24 constitute a receiving apparatus according to the present invention.

  The channel selection processing unit 11 constitutes a control unit in the present invention together with the control unit 24, and controls the switching of the channel of the broadcast signal Sb received by the tuner 12 according to the control of the control unit 24. The tuner 12 corresponds to a receiving unit in the present invention. As an example, the tuner 12 receives a broadcast signal Sb of a channel designated by the channel selection processing unit 11 from broadcast signals Sb of each channel in 110-degree CS digital broadcasting, and receives video. Output to the audio processing unit 14. Further, the tuner 12 extracts EPG data De for displaying an EPG (Electronic Program Guide) from the broadcast wave of the 110-degree CS digital broadcast, and sends it to the control unit 24 via the channel selection processing unit 11. Output.

  The preset information storage unit 13 stores association data in which each direct channel selection key 32 (see FIG. 2) of the remote controller 3 is associated with a channel (channel number) assigned to each direct channel selection key 32. The video / audio processing unit 14 outputs the video signal Sp1 and the audio signal Ss1 based on the broadcast signal Sb output from the tuner 12 to the video output unit 15 and the audio output unit 17, respectively, under the control of the control unit 24. The video output unit 15 converts the video signal Sp1 output from the video / audio processing unit 14 into a video signal Sp2 for video display under the control of the control unit 24 and outputs the video signal Sp2 to the display unit 16. In addition, the video output unit 15 displays a video signal Sp2 for displaying a viewing restriction notification screen Pr1 (see FIG. 7) and a selection restriction notification screen Pr2 (see FIG. 11), which will be described later, under the control of the control unit 24. Based on the video data stored in the memory, it is generated and output to the display unit 16. As an example, the display unit 16 includes an optical engine and a screen panel (both not shown), and the projection light that is light-modulated based on the video signal Sp2 from the video output unit 15 is applied to the screen panel from the back side. Various images are displayed by projecting.

  The audio output unit 17 amplifies the audio signal Ss1 output from the video / audio processing unit 14 and outputs the audio signal Ss2 to the speaker 18. The speaker 18 outputs a sound based on the sound signal Ss2 output from the sound output unit 17. The “voice” in the present specification includes not only a human voice but also various “sounds” such as bird calls, wind sounds, and music. Under the control of the control unit 24, the channel selection / program information storage unit 19 performs channel data Dc indicating the channel selected immediately before power-off and channel switching, and various types of programs related to the program broadcast on the channel. Program data Db indicating the information is stored. The restriction information storage unit 20 stores rating level data Dr used in the viewing restriction process 50 (see FIG. 5) executed by the control unit 24 under the control of the control unit 24. Here, the rating level data Dr indicates whether or not the program is suitable for young people, indicating that the minimum age of the target audience (generally, the larger the numerical value, the more inappropriate it is for young people). This is data indicating the rating level expressed by (1), and is generated by the control unit 24 based on the EPG data De. Further, the restriction information storage unit 20 stores skip channel data Ds used in the channel skip processing 70 (see FIG. 9) executed by the control unit 24. The personal identification number storage unit 21 stores personal identification number data Dn for a personal identification number for releasing the viewing restriction set in the viewing restriction setting process 40. The light receiving unit 22 receives the infrared signal Si output from the remote controller 3 and outputs an operation signal So. The key input processing unit 23 outputs a control signal Sc corresponding to the operation signal So output from the light receiving unit 22 to the control unit 24.

  The control unit 24 controls the channel selection processing unit 11, the video / audio processing unit 14, the video output unit 15 and the audio output unit 17 in accordance with the control signal Sc output from the key input processing unit 23, that is, the operation of each operation key on the remote controller 3. Control etc. Further, the control unit 24 follows the operation of a predetermined operation key on the remote controller 3, the viewing restriction setting process 40 shown in FIG. 4, the viewing restriction process 50 shown in FIG. 5, the selection restriction setting process 60 shown in FIG. The channel skip process 70 shown in FIG.

  The remote controller 3 is formed separately from the main body 2 as shown in FIG. The remote controller 3 is configured by arranging various operation keys such as a power key 31, twelve direct channel selection keys 32, a channel up key 33a, a channel down key 33b, a viewing restriction setting key 34, and a selection restriction setting key 35. When these operation keys are operated, an infrared signal Si corresponding to each operation key is output (transmitted).

  Next, the overall operation of the television 1 will be described with reference to the drawings. In the initial state, it is assumed that the viewing restriction for restricting viewing of the program is set to “invalid”. Also, it is assumed that the personal identification number data Dn is already registered (stored) in the personal identification number storage unit 21. Further, in this television 1, every time the power is turned off and the channel is switched, the control unit 24 performs the above-described channel data Dc for the channel selected immediately before and the program broadcast on the channel. The program data Db is stored in the channel selection / program information storage unit 19. Therefore, it is assumed that the channel selection / program information storage unit 19 stores, for example, channel data Dc and program data Db of 110 channels selected immediately before the power is turned off.

  In the television 1, when the power key 31 of the remote controller 3 is operated, the remote controller 3 outputs an infrared signal Si corresponding to the power key 31, and the light receiving unit 22 receives the infrared signal Si and receives the operation signal So. Output. Next, the key input processing unit 23 outputs the operation signal So, that is, the control signal Sc corresponding to the power key 31 to the control unit 24. In response to this, the control unit 24 controls a power supply unit (not shown) to supply power to each unit of the television 1. Next, the control unit 24 reads the channel data Dc from the channel selection / program information storage unit 19 and specifies the channel (110 channel in this example) that was selected immediately before power-off based on the channel data Dc. . Subsequently, the control unit 24 controls the channel selection processing unit 11 to cause the tuner 12 to extract the 110-channel broadcast signal Sb. In addition, the control unit 24 controls the tuning processing unit 11 to cause the tuner 12 to extract the EPG data De.

  Next, the video / audio processing unit 14 outputs the video signal Sp1 and the audio signal Ss1 based on the broadcast signal Sb output from the tuner 12 to the video output unit 15 and the audio output unit 17, respectively. Subsequently, the video output unit 15 converts the video signal Sp1 into a video signal Sp2 for video display and outputs the video signal Sp2 to the display unit 16. Next, the optical engine of the display unit 16 projects the projection light that is light-modulated based on the video signal Sp2 onto the screen panel. The audio output unit 17 amplifies the audio signal Ss1 output from the video / audio processing unit 14 and outputs the audio signal Ss2 to the speaker 18. As a result, the 110-channel television image Pt (see FIG. 2) is displayed on the display unit 16 and the 110-channel sound is output from the speaker 18.

  Here, when watching a 110-channel program as a family, broadcasting of a program inappropriate for children (hereinafter, this type of program is also referred to as an “adult program”) started on the 110-channel. Sometimes (see FIG. 3), for example, the channel up key 33a of the remote controller 3 is operated in order to switch the channel to another channel and avoid viewing by a child. At this time, the remote controller 3 outputs an infrared signal Si corresponding to the channel up key 33a, and the key input processing unit 23 outputs a control signal Sc corresponding to the channel up key 33a. In response to this, the control unit 24 executes a channel switching process. Specifically, the control unit 24 controls the tuning processing unit 11 to cause the tuner 12 to extract the broadcast signal Sb of 111 channels instead of the 110 channels. Next, the video / audio processing unit 14, the video output unit 15, the display unit 16, the audio output unit 17 and the speaker 18 operate as described above to replace the 110-channel television video Pt as shown in FIG. , 111 channel TV image Pt is displayed and 111 channel sound is output instead of 110 channel sound.

  In addition, the control unit 24 generates channel data Dc indicating the 110 channels selected immediately before the channel switching (immediately before the operation of the channel up key 33a) and stores the channel data Dc in the channel selection / program information storage unit 19. The control unit 24 also shows program data indicating information related to the program including the rating level given to the adult program broadcast on the 110 channel immediately before the channel switching based on the EPG data De output from the tuner 12. Db is generated and stored in the channel selection / program information storage unit 19.

  Next, when the above-mentioned adult program broadcast on the 110 channel is to be subject to viewing restriction, the viewing restriction setting key 34 (predetermined operation key in the present invention) of the remote controller 3 is operated (in the present invention). Predetermined operation). At this time, the key input processing unit 23 outputs a control signal Sc corresponding to the viewing restriction setting key 34, and in response thereto, the control unit 24 executes the viewing restriction setting process 40 shown in FIG. In the viewing restriction setting process 40, the control unit 24 reads the program data Db from the channel selection / program information storage unit 19 (step 41). Next, the control unit 24 extracts a rating level included in the program data Db, generates rating level data Dr for the rating level, and stores it in the restriction information storage unit 20 (step 42). Subsequently, the control unit 24 sets the viewing restriction to “valid” (step 43), and ends the viewing restriction setting process 40. As a result, the above-mentioned program for adults that was broadcast on the 110 channel selected immediately before the channel switching is set as a viewing restriction target. In this case, in the television 1, it is possible to set the program broadcast on the channel immediately before the channel switching as the viewing restriction target simply by operating the viewing restriction setting key 34. For this reason, compared with the structure which inputs various setting values from a setting screen, it can set easily in a short time.

  Next, for example, assuming that the above-described program for adults has already ended, as shown in FIG. 6, when the channel down key 33b is operated to switch from the 111 channel to the 110 channel, the control unit 24 However, the above-described channel switching process is executed in accordance with the control signal Sc corresponding to the channel down key 33b output from the key input processing unit 23. In this case, since the viewing restriction is set to “valid” in the viewing restriction setting process 40, the control unit 24 executes the viewing restriction process 50 shown in FIG. 5 prior to the channel switching process.

  In the viewing restriction process 50, the control unit 24 is currently broadcasting on the channel corresponding to the operation of the channel down key 33b (in this case, 110 channel, which is one channel number smaller than the 111 channel selected immediately before the operation). The rating level assigned to the program is specified based on the EPG data De output from the tuner 12 (step 51). Next, the control unit 24 reads the rating level data Dr from the restriction information storage unit 20 (step 52). Subsequently, the control unit 24 indicates a rating level in which a rating level (hereinafter, this rating level is also referred to as “comparison rating level”) assigned to a program currently broadcast on the 110 channel is indicated by the rating level data Dr. (Hereinafter, this rating level is also referred to as “comparison rating level”) or not (step 53). In this case, for example, when the above-mentioned program for adults is terminated on channel 110 and the comparison target rating level of the currently broadcast program is lower than the comparison rating level, the control unit 24 switches the channel switching described above. The process is executed (step 54), and the viewing restriction process 50 is terminated. As a result, as shown in FIG. 6, the 110-channel television image Pt is displayed instead of the 111-channel television image Pt, and the 110-channel audio is output instead of the 111-channel audio.

  On the other hand, when the above-mentioned program for adults continues on channel 110, since the comparison target rating level and the comparison rating level are the same value, the control unit 24 performs step 53 of the viewing restriction process 50 described above. The comparison target rating level is determined to be equal to or higher than the comparison rating level. At this time, the control unit 24 controls the video output unit 15 to output the video signal Sp2 for displaying the viewing restriction notification screen Pr1. Next, when the display unit 16 operates as described above, as shown in FIG. 7, a viewing restriction notification screen Pr1 for notifying that viewing is restricted is displayed instead of the 111-channel television image Pt ( Step 55). As a result, viewing of the above-described adult program is restricted.

  In this case, when releasing the viewing restriction, the personal identification number is input using the direct channel selection key 32 of the remote controller 3 as a numeric key. At this time, the control unit 24 compares the registered personal identification number indicated by the personal identification number data Dn stored in the personal identification number storage unit 21 with the input personal identification number. After the restriction is released and the above-described channel switching process is performed, the viewing restriction process 50 ends. As a result, the television video Pt of the program being broadcast on the 110 channel is displayed.

  Thereafter, the control unit 24 performs the above-described viewing restriction processing 50 according to the operation of the direct channel selection key 32, the channel up key 33a, and the channel down key 33b of the remote controller 3 in a state where the viewing restriction is set to be valid. By executing, the viewing of the program whose comparison target rating level is equal to or higher than the comparison rating level is restricted. The control unit 24 also executes the viewing restriction process 50 when a program broadcast on the selected channel is newly started (the program is switched). That is, the control unit 24 executes the viewing restriction process 50 for all programs to which a rating level equal to or higher than the comparative rating level is given as a viewing restriction target.

  On the other hand, in the television 1, for example, selection (switching to the channel) of the channel (110 channel in the above example) on which the above-described program for adults was broadcast can be restricted. In this case, in the above example, after switching from the 110 channel on which the program for adults was broadcast to the 111 channel, the selection restriction setting key 35 (the predetermined operation key in the present invention) of the remote controller 3 is operated (the present invention). Predetermined operation). At this time, the control unit 24 executes the selection restriction setting process 60 shown in FIG. 8 according to the control signal Sc corresponding to the selection restriction setting key 35 output from the key input processing unit 23.

  In the selection restriction setting process 60, the control unit 24 reads the channel data Dc from the channel selection / program information storage unit 19 (step 61). Next, the control unit 24 stores the read channel data Dc as skip channel data Ds in the restriction information storage unit 20 (step 62). Subsequently, the control unit 24 sets the selection restriction to “valid” (step 63), and ends the selection restriction setting process 60. As a result, the 110 channels selected immediately before the channel switching are set as selection restriction targets. In this case, in the television 1, the channel selection itself immediately before the channel switching can be limited only by operating the selection limit setting key 35. For this reason, it is possible to quickly and easily limit viewing of programs for adults without inputting various setting values for restricting viewing from the setting screen for each program.

  Next, when the 111 channel program is being viewed with the selection restriction set to “valid”, for example, when the channel up key 33 a is operated, the control unit 24 starts from the key input processing unit 23. In accordance with the control signal Sc corresponding to the output channel up key 33a, the channel skip processing 70 shown in FIG. 9 is executed. In this channel skip processing 70, the control unit 24 sets the channel data Dc for the channel (111 channels in this case) selected immediately before the operation of the channel up key 33a and the program for the program broadcast on that channel. Data Db is stored in the channel selection / program information storage unit 19 (step 71). Next, the control unit 24 specifies the next channel (for example, 112 channel whose channel number is one greater than 111 channel) designated by the operation of the channel up key 33a (step 72), and skips corresponding to that channel. It is determined whether or not the channel data Ds is stored in the restriction information storage unit 20 (step 73). In this case, since the corresponding skip channel data Ds (corresponding to the 112 channel) is not stored in the restriction information storage unit 20, the control unit 24 executes the above-described channel switching process (step 74). Thereby, the 112-channel television image Pt is displayed and the 112-channel sound is output.

  On the other hand, when the channel restriction key 33b is operated as shown in FIG. 10 while viewing a 111-channel program with the selection restriction set to “valid”, the control unit 24 In the channel skip processing 70, the next channel designated by the operation of the channel down key 33b (in this example, the 110 channel whose channel number is one smaller than the 111 channel) is specified (step 72), and this channel is supported. It is determined whether or not the skip channel data Ds to be stored is stored in the restriction information storage unit 20 (step 73). In this case, since the corresponding skip channel data Ds (corresponding to 110 channels) is stored in the restriction information storage unit 20, the control unit 24 has 109 channels (the next channel) whose channel number is one less than the 110 channels. ) Is specified (step 72), step 73 is executed. In this case, since the skip channel data Ds for the 109 channel is not stored in the restriction information storage unit 20, the control unit 24 executes a channel switching process (step 74) and ends the channel skip process 70. As a result, as shown in FIG. 10, the 110 channel is skipped (interlaced), the 109 channel TV image Pt is displayed, and the 109 channel sound is output. That is, selection (switching) of 110 channels is limited.

  On the other hand, when the 111 channel program is being viewed with the selection restriction set to “valid”, when the direct channel selection key 32 corresponding to the 110 channel is operated, the control unit 24 outputs the video. The unit 15 is controlled to output a video signal Sp2 for displaying the selection restriction notification screen Pr2. Next, as the display unit 16 operates as described above, as shown in FIG. 11, a selection restriction notification screen Pr2 for notifying that it is a selection restriction target is displayed instead of the 111-channel television image Pt. . In this case, when canceling the selection restriction, the password is input as described above. At this time, the control unit 24 compares the registered personal identification number indicated by the personal identification number data Dn with the input personal identification number, and when the two coincide with each other, the selection restriction is canceled. As a result, the television video Pt of the program being broadcast on the 110 channel is displayed.

  As described above, according to the television 1, when a predetermined operation is performed after the channel is switched, the control unit 24 executes the viewing restriction setting process 40, so that the channel switching can be performed only by performing the predetermined operation. A program broadcast on the immediately preceding channel can be set as a viewing restriction target. For this reason, compared with the configuration in which various setting values are input from the setting screen, a complicated operation for inputting a condition for specifying a program can be eliminated. Viewing restriction can be set. Therefore, for example, even when an inappropriate program broadcast is started for the child while watching the television 1 with the family, the inappropriate operation by the child can be performed only by switching the channel and performing a predetermined operation. Viewing of the program can be avoided reliably.

  Further, according to the television 1, when the viewing restriction setting key 34 of the remote controller 3 is operated, the control unit 24 executes the viewing restriction setting process 40, thereby operating the viewing restriction setting key 34 (one operation ( Since the setting of the viewing restriction target can be performed by one action), the viewing restriction can be set more easily in a shorter time.

  Further, according to the television 1, the control unit 24 targets all programs to which a rating level equal to or higher than the rating level assigned to the program broadcast at the time immediately before the channel switching is set as a viewing restriction target. By setting, for example, these programs can be set as viewing restriction targets quickly and easily without individually performing setting operations for other programs that are considered inappropriate for children. it can.

  In addition, according to the television 1, when a predetermined operation is performed after the channel is switched, the control unit 24 executes the selection restriction setting process 60, so that only the predetermined operation is performed before the channel switching. A channel can be set as a selection restriction target whose selection itself is restricted. For this reason, for example, compared with a configuration in which various setting values are input from the setting screen, it is possible to eliminate a complicated operation of inputting a condition for specifying a channel. It is possible to easily set selection restrictions. Therefore, for example, even if the broadcasting of an inappropriate program for the child starts while watching the TV 1 with the family, the inappropriate program by the child can be performed only by switching the channel and performing a predetermined operation. Can be surely avoided.

  In addition, according to the television 1, when the selection restriction setting key 35 of the remote controller 3 is operated, the control unit 24 executes the selection restriction setting process 60, thereby operating one operation of operating the selection restriction setting key 35 ( Since the setting of the viewing restriction target can be performed by one action), the viewing restriction can be set more easily in a shorter time.

  Further, according to the television 1, when the channel up key 33a or the channel down key 33b of the remote controller 3 is operated in a state where the selection restriction is valid, the control unit 24 executes the channel skip processing 70, for example. Even if an attempt is made to select a channel that is set as a selection restriction target, it is possible to automatically select another channel that can be selected by skipping that channel. For this reason, for example, when a channel set as a selection restriction target is selected, a non-display state or a message indicating that the selection restriction target is displayed is displayed. The operability can be improved as compared with the configuration in which another channel that can be selected by requesting the operation is selected.

  In addition, this invention is not limited to said structure. For example, although an example in which the display unit 16 is configured with an optical engine and a screen panel has been described above, a CRT, a liquid crystal display panel, a plasma display, or the like may be employed as the display unit.
