  In addition, the selection image generation unit 114 displays the images corresponding to the video signals S1 to S3 input from the video signal input terminals 191 to 193 set as candidates by the candidate setting unit 116 so as to be distinguishable from other images. The selection image information to be displayed is generated, and the candidate setting unit 116 generates selection image information for displaying moving images corresponding to the video signals S1 to S3 input from the video signal input terminals 191 to 193 set as candidates. Is.

  Further, the selection image generation unit 114 has a plurality of images (or moving images) corresponding to the video signals S1 to S3 input from the video signal input terminals 191 to 193 determined to be input with the video signal by the input determination unit 111. The selected image information for displaying the name information (here, “terminal 191”, etc.) of the video signal input terminals 191 to 193 corresponding to the image (or moving image) as character information in association with the image) It is.

  For example, the video signal S1 from the video signal input terminal 191 is input, and the video signal S2 from the video signal input terminal 192 is input while the video corresponding to the video signal S1 is displayed on the display 183. In this case, as shown in FIG. 6B, which will be described later, selected image information for generating a moving image corresponding to the video signal S1 and an image corresponding to the video signal S2 as one image on the display 183 is generated. Is done. In addition, the name information of the video signal input terminals 191 to 193 from which the moving image is output is displayed as “terminal 191” below the moving image corresponding to the video signal S1, and the image corresponding to the video signal S2. The selection image information for displaying the name information of the video signal input terminals 191 to 193 from which this image is output as “terminal 192” is generated below.

  The image display unit 115 (corresponding to an image display unit) displays selected image information generated by the selected image generation unit 114 on the display 183 as a selection screen.

  Candidate setting unit 116 (corresponding to a part of candidate setting means) accepts an operation input from the user via operation unit 14 shown in FIG. 2 and remote control 2 shown in FIG. 1, and based on the accepted operation input. Thus, video signal input terminals 191 to 193 corresponding to one image (or moving image) among a plurality of images (or moving images) displayed by the image display unit 115 are output to the display 183. It is set as a candidate of 191 to 193.

  For example, the candidate setting unit 116 is provided in the remote controller 2 and receives an operation input from the user via a direction key that is pressed when moving the candidate setting state in each of the up, down, left, and right directions. For example, when the right direction key is pressed, the candidate setting unit 116 moves the candidate setting state to the image (or moving image) on the right side of the currently set image (or moving image) (= The right image (or moving image) is set as a candidate).

  The input selection unit 117 (corresponding to a part of the input selection means) receives an operation input from the user via the operation unit 14 shown in FIG. 2 and the remote controller 2 shown in FIG. 1, and based on the received operation input. Thus, the video signal input terminals 191 to 193 set as candidates by the candidate setting unit 116 are selected as the video signal input terminals 191 to 193 to be output to the display 183.

  For example, the input selection unit 117 is disposed in the remote controller 2 and receives an operation input from the user via a determination key that is pressed when determining a selection. That is, the input selection unit 117 selects one image set as a candidate by the candidate setting unit 116 from among a plurality of images (or moving images) displayed by the image display unit 115 when the enter key is pressed. (Or a moving image) is selected as video signal input terminals 191 to 193 to be output to the display 183.

The selected image information is displayed on the display 183 as a selection screen by the unit 115 (S111). Then, the candidate setting unit 116 determines whether or not an operation input for setting candidates for the video signal input terminals 191 to 193 to be output to the display 183 has been received (S113). If it is determined that an operation input for setting a candidate has not been received (NO in S113), the process is set to a standby state.

  When it is determined that an operation input for setting a candidate has been accepted (YES in S113), the selected image information for displaying moving images corresponding to the video signals S1 to S3 set as candidates by the selected image generation unit 114 And the selected image information is displayed on the display 183 as a selection screen by the image display unit 115 (S115). Next, the input selection unit 117 determines whether or not an operation input for selecting the video signal input terminals 191 to 193 to be output to the display 183 has been received (S117). If it is determined that the operation input for selecting the video signal input terminals 191 to 193 to be output to the display 183 is not accepted (NO in S117), the process returns to step S113, and the processes after step S113 are repeated. Executed.

  When it is determined that an operation input for selecting the video signal input terminals 191 to 193 to be output to the display 183 is accepted (YES in S117), or when the process of step S109 is completed, the display switching unit 118 In order to output the video corresponding to the selected video signal input terminals 191 to 193 to the display 183, a switching signal is output to the input switching circuit 194 (S119), and the processing is terminated.

Further, since a moving image corresponding to the video signal S3 from the video signal input terminal 193 is displayed, the content of the video signal S3 from the video signal input terminal 193 can be confirmed in detail.

  In this way, when there are a plurality of video signal input terminals 191 to 193 determined to receive the video signals S1 to S3, the video signal input determined to receive the video signals S1 to S3 is input. Selection image information including a plurality of pieces of image information corresponding to the video signals S1 to S3 input from the terminals 191 to 193 and displayed on the display 183 as one image is generated. Further, the generated selected image information is displayed on the display 183, and an operation input from the user is received via the remote controller 2. Based on the received operation input, one image is displayed from the displayed plurality of images. The video signal input terminals 191 to 193 corresponding to are selected. Since the video corresponding to the video signals S1 to S3 input from the selected video signal input terminals 191 to 193 is output to the display 183, the video desired by the user is output to the display 183 with a simple operation. can do.

  That is, by viewing a plurality of pieces of image information corresponding to the video signals S1 to S3 included in the selected image information, a video desired to be viewed is selected with reference to the image information included in the selected image displayed on the display 183. Therefore, the video that the user desires to view can be output to the display 183 easily and accurately.
