The operation panel includes a cursor key 91 that is operated to move a cursor, which will be described later, on the display unit 16 in the horizontal and vertical directions on the screen, a numeric keypad 92 that is operated to directly specify a desired channel, and operation details. A determination key 93 that is operated to determine an image, and a menu key 94 that is operated to select video specifications (requirements for specifying a video display method, such as contrast and hue). The type of keys provided on the remote controller 19 is not limited to this.

  A channel map 51 is stored in the memory 15. In the channel map 51, all channel numbers corresponding to broadcast signals receivable via the antenna 11 of FIG. 1 are registered.

  This television is realized by computer hardware and software executed by the MPU 14. Generally, such software is stored and distributed in a recording medium such as the memory card 21, read from the recording medium by the memory card drive 21, and temporarily stored in the memory 15. Further, it is executed by the MPU 14. The computer hardware itself is general. Therefore, the most essential part of the present invention is software recorded on a recording medium such as the memory card 21.

  Referring to FIG. 2, the program executed on the television executes the following control with respect to adjustment of display specifications.

  In step 100 (hereinafter, step is abbreviated as S), the remote control receiving unit 18 receives a user command by receiving a signal from the remote control 19.

  In S <b> 102, remote control receiving unit 18 outputs the signal received from remote control 19 to MPU 14. The MPU 14 analyzes the signal output from the remote control receiver 18. When the signal is analyzed, the MPU 14 determines whether the menu key 94 of the remote controller 19 is pressed based on the signal analyzed by itself. If it is determined that menu key 94 has been pressed (YES in S102), the process proceeds to S104. If not (NO in S102), the process proceeds to S106.

  In S104, processing unit 17 generates a second video signal. In the present embodiment, the “second video signal” is a video image that is displayed at a position closer to the corner than the center of the screen and that is the same video image regardless of the specification of the item to be changed. is there. In the present embodiment, “item to be changed” represents one item of video specifications. “Video specification” represents the video display specification. The “video specification” includes video contrast, video brightness, video aspect ratio, video hue, and the like. When the signal is generated, the processing unit 17 outputs the generated signal to the display unit 16 through a terminal included therein. The display unit 16 displays an image according to the signal generated by the processing unit 17. As a result, the display unit 16 displays the item name at the corner of the screen. In the present embodiment, the processing unit 17 generates a video signal representing an item name so as to correspond to the number of times the menu key 94 is pressed.

  In S106, the MPU 14 determines whether or not the cursor key 91 of the remote controller 19 has been pressed. If it is determined that cursor key 91 has been pressed (YES in S106), the process proceeds to S108. If not (NO in S106), the process proceeds to S110.

  In S108, the processing unit 17 generates a second video signal of a video that is displayed at a position closer to the corner than the center of the screen and is the same regardless of the specification of the item to be changed. . When generating the video signal, the processing unit 17 associates the brightness of the character color with the specification of the item to be changed. When the video signal is generated, the processing unit 17 generates a control signal for controlling the display specifications of the video under the control of the MPU 14. When the control signal is generated, the processing unit 17 outputs the control signal to the display unit 16 through its own terminal. The output terminal of the processing unit 17 outputs the second video signal and the control signal generated by itself to the display unit 16 that displays the video. The display unit 16 displays an image according to the first video signal 26 extracted by the tuner 12, the second video signal generated by the processing unit 17, and the control signal. As a result, the video specifications are changed.

  In S110, MPU 14 determines whether or not any key of remote controller 19 is pressed. If it is determined that none has been pressed (YES in S110), the process proceeds to S112. If not (NO in S110), the process proceeds to S116.

  In S112, the MPU 14 refers to the time counted by the timer 41, so that a certain time (30 seconds in this embodiment) elapses after either the menu key 94 or the cursor key 51 is pressed. Determine whether or not. The memory 15 stores in advance the time at which one of the menu key 94 and the cursor key 91 was last pressed. If it is determined that a certain time has elapsed (YES in S112), the process proceeds to S114. If not (NO in S112), the process proceeds to S100.

  In S114, processing unit 17 ends the generation of the signal for displaying the item name. When the generation ends, the item name disappears from the screen of the display unit 16.

The operation of the television based on the above structure and flowchart will be described.
The remote control receiver 18 receives a signal from the remote controller 19 (S100). When the signal is received, the MPU 14 determines whether or not the menu key 94 of the remote controller 19 has been pressed (S102). In this case, if menu key 94 is pressed (YES in S102), processing unit 17 generates a second video signal. The “second video signal” refers to a video signal that is displayed at a position closer to the corner than the center of the screen and that is the same regardless of the specification of the item to be changed. As a result, the processing unit 17 sends a command for selecting an item to be changed in the video display specifications (in this embodiment, pressing the menu key 94 corresponds to such command). When the receiving unit 18 accepts the video signal, the video image is displayed at a position closer to the corner than the center of the screen and is the same regardless of the specification of the item to be changed. The display unit 16 displays the item name at the corner of the screen (S104). FIG. 3 is a diagram showing the screen of the display unit 16 at this time.

  When the item name is displayed, through the process of S100, the MPU 14 determines whether or not the menu key 94 has been pressed (S102). In this case, if menu key 94 is pressed again (YES in S102), display unit 16 displays the item name in the corner of the screen (S104). Thereby, the item name displayed on the display unit 16 changes every time the menu key 94 is pressed.

  By repeatedly pressing the menu key 94, the item name is completed, and when the item name (contrast) that the user desires to adjust is displayed, the user stops pressing the menu key 94. In this case, since menu key 94 is not pressed (NO in S102), MPU 14 determines whether or not cursor key 91 is pressed (S106). In this case, since the user presses cursor key 91 (YES in S106), processing unit 17 generates the second video signal and the control signal. As a result, when the remote control receiving unit 18 receives a command for designating the specification (in this embodiment, pressing the cursor key 91 is equivalent to issuing such a command), the processing unit 17 A second video signal is generated that is a video that is displayed at a position closer to the corner than the center and that is the same video regardless of the specification of the item to be changed. When the remote control receiving unit 18 receives a command designating the specification, the processing unit 17 generates a control signal for controlling the video display specification. The display unit 16 displays an image according to the first video signal 26 extracted by the tuner 12, the second video signal generated by the processing unit 17, and the control signal. Thereby, the specification (in this case, the contrast of the video) of the video displayed on the display unit 16 is changed (S108). FIG. 4 is a diagram showing a screen of the display unit during adjustment of video specifications (in this case, video contrast). As apparent from FIGS. 3 and 4, only the item name “contrast” is displayed. The video specifications (in this case, the video contrast) are not displayed as numerical values or graphs.

  Thereafter, the processing of S100 to S108 is repeated. The user operates the cursor key 91 while observing the change in the image and the change in the image brightness of the character representing the item name (the brightness corresponds to the color density), thereby specifying the image specification (FIG. 4). Adjust the contrast). In the case of the present embodiment, the brightness of the item name is adjusted so that the brightness becomes higher as the value obtained by quantifying the video specification decreases.

  When the change of the specification (in this case, the contrast of the image) is completed and the user lifts his / her finger from the key of remote controller 19 (NO in S106), MPU 14 determines whether any key of remote controller 19 is pressed. Judgment is made (S110). In this case, no key is pressed (YES in S110). The MPU 14 determines whether or not a certain time has elapsed after either the menu key 94 or the cursor key 91 is pressed (S112). Since the predetermined time has not elapsed at the beginning (NO in S112), the processes of S100 to S112 are repeated. Thereafter, since a certain time has elapsed (YES in S112), processing unit 17 ends the generation of the second video signal. The item name disappears from the screen of the display unit 16 (S114). FIG. 5 shows a screen of the display unit 16 at this time. Thereby, the adjustment of the video specification is completed.

  As described above, the television according to the present embodiment has the same character image (in the present embodiment, only the item name) in the corner of the screen regardless of the specification of the item to be changed. indicate. Since only the item name is displayed in the corner of the screen, the space for blocking the program video is small. Since such a space is small, a video showing only the item name does not interfere with the video of the program. In addition, since the video representing only the item name is displayed, it is possible to adjust the video specifications while pouring the user's line of sight onto the video. Since the “video specification is adjusted while pouring the user's line of sight into the video”, the user can easily grasp the content of the video. As a result, the video can be displayed so that it can be easily seen, and the contents can be easily grasped.

  As a modification, in S108, the processing unit 17 is a video displayed as a second video signal at a position closer to the corner than the center of the screen, and is the same regardless of the specification of the item to be changed. You may generate | occur | produce the signal of the image | video which is a character image and a character color respond | corresponds to the specification of the item to change. In this case, the processing unit 17 may generate a video signal in which the character color hue corresponds to the specification of the item to be changed as the second video signal. In this case, as the video specification changes, a phenomenon such as the color of the item name changing from warm to cold appears. Instead of the hue of the character color, the specification of an item whose saturation of the character color is changed may be supported.

  As a modification, in S108, the processing unit 17 may generate the second video signal so that a part of the item name is missing. The processing unit 17 is an image displayed at a position closer to the corner than the center of the screen, and is an image of the same character regardless of the specification of the item to be changed, and the character according to the specification of the item to be changed A video signal in which a part of the image is cut off may be generated. FIG. 6 is a diagram showing the screen of display unit 16 at the time when the adjustment of specifications is started in such a case. FIG. 7 is a diagram showing a screen of the display unit 16 during specification adjustment. FIG. 8 is a diagram showing the screen of the display unit 16 at the time when the adjustment of the specification is finished.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
