  The “telop data detection area” is an area surrounded by a dotted line 200 as shown in (1) of FIG. This area is an area to be detected for telop data.

  The “telop data correction reference area” is an area surrounded by a dotted line 201 and a dotted line 200 as shown in (2) of FIG. This area is an area to be detected for hue data that is used as a reference when correcting the pixels constituting the telop data.

  Next, the hue-color tone palette 300 will be described.

  FIG. 6 is a diagram illustrating the hue-color tone palette 300.

  The hue-tone palette 300 indicates the relationship between hue and tone.

  The hue-color palette 300 is a circular palette that displays representative hues at equal intervals along the circumference. Hue is a parameter representing “difference in hue”. As shown in FIG. 6, for example, “red”, “blue”, “green”, and “yellow” are displayed at equal intervals along the circumference as the hue.

  In the hue-color tone palette 300, “color tone” is displayed along the radial direction. The color tone is a parameter that takes “lightness” and “saturation” into consideration. Lightness refers to the degree of brightness of a color according to the luminance of light, and saturation refers to the vividness of a color, that is, the degree of purity of the color. For example, a color with high saturation becomes a vivid primary color and changes to a color that does not feel dull as the saturation decreases.

  For example, as shown in FIG. 6, in the hue-color palette 300, a color with a low color tone is displayed on the center side of the circle along the radial direction, and a color with a high color tone is displayed on the circumferential side. .

  The telop data detection unit 101 and the telop data correction unit 102 use the hue-color tone palette 300.

  FIG. 7 is a flowchart illustrating an example of the flow of processing executed by the telop data detection unit 101.

  Here, the telop data detection 101 uses the contents of the telop data detection area / correction reference area setting contents set by the telop data detection area / telop data correction reference area setting unit 105 described with reference to FIG. Process.

  The telop data detection unit 101 detects the hue of each pixel constituting the telop data correction reference area (step S100). As shown in (2) of FIG. 5, it is detected that the hue displayed by the pixel group constituting the area (Area1) is light blue, and the hue displayed by the pixel group constituting the area (Area2) is yellow-green. Detect that there is.

  Further, the telop data detection unit 101 displays the hue detected in step S100 on the hue-color tone palette 300 (step S101).

  As shown in FIG. 8, the yellow-green color detected in the area (Area 2) included in the telop data correction reference area is displayed between the hues “yellow” and “green” displayed on the hue-tone palette 300. (300a), and the light blue detected in the area (Area 1) included in the telop data correction reference area is displayed (300b) between the hues “green” and “blue”.

  As shown in FIG. 9, a similar color region is set on the hue-color palette Palette 300 using the hue displayed on the hue-color palette Palette 300 in Step S301 (Step S102). The similar color region is a region indicating a color that is considered to be a similar color to the hue color displayed on the palette in step S301. For example, as shown in FIG. 8, a similar color region 301a including yellow green (300a) is a region indicating a color considered to be similar to yellow green, and a similar color region 301b including light blue (300b) is This is an area indicating a color considered to be a color similar to light blue. Setting this similar color region means setting a threshold value for determining whether the hue is a similar hue or a different hue.

  As an example of setting the similar color area, the similar color area is set so as to include the hue colors (300a, 300b) displayed on the palette in step S301. At this time, the central angle (302a, 302b) of the similar color region can be set by the user.

  The telop data detection unit 101 detects a hue different from the similar color area (300a, 300b) set in step S102 among the hues of the pixels constituting the telop data detection area (step S103).

  As shown in FIG. 10, the hue displayed by the pixel group constituting the area (Area 3) and the area (Area 4) is “red” having a hue different from that of the similar color area (300a, 300b) set in step S102. Detect that there is.

  Further, the telop data detection unit 101 displays the hue detected in step S103 on the hue-color tone palette 300 (step S104).

  As shown in FIG. 11, the red color detected in the area (Area 3) and the area (Area 4) included in the telop data detection area is displayed in the vicinity of the hue “red” displayed on the hue-tone palette 300 (300c). )

  Next, processing executed by the telop data correction unit 102 will be described.

  FIG. 12 is a flowchart illustrating an example of the flow of processing executed by the telop data correction unit 102.

  Here, the telop data correction unit 102 uses the contents of the telop data detection area / correction reference area setting contents set by the telop data detection area / telop data correction reference area setting unit 105 described with reference to FIG. Perform the process.

  The telop data correction unit 102 designates the area (Area 3) and the area (Area 4), which are detected as having a hue of “red” in step S104, as correction target pixels (step S200).

  Based on the hue displayed by the pixels in the area other than the areas (Area 3 and Area 4) designated as the correction target pixels in step S200 in the telop data detection area, border lines that delimit these areas are determined (step S201).

  As shown in (1) of FIG. 13, the border1 and the border2 that divide the region (Area 1) having a light blue hue and the region (Area 3) having a yellow green hue are determined.

  Further, the telop data correction unit 102 determines a border line provided in the region designated as the correction target pixel in step S200 based on the arrangement tendency of the border line determined in step S201 (step S202).

  As shown in (2) of FIG. 13, the pixel is specified as a correction target pixel based on the arrangement tendency of the border1 and the border2 that divide the area (Area1) having a light blue hue and the area (Area3) having a yellowish green hue. The border 3 provided in the area (Area 3) whose hue is “red” is determined.

  As shown in FIG. 14, in the area (Area 3) in FIG. 13 (2), the upper part divided by the border 3 is referred to as Area 3a, and the lower part is referred to as Area 3b.

  Using the hue-tone palette 300 shown in FIG. 15, a color for correcting the area designated as the correction target pixel in step S200 is selected (step S203).

  As shown in FIG. 15, “dark yellow-green” (300d) having a lower hue than yellow green that is the hue of the area (Area 3) and “dark light blue” having a hue lower than the light blue that is the hue of the area (Area 1). (300e) is selected.

  The user can select how low the color tone is to be selected compared to the yellow-green color that is the hue of the area (Area 3) and the light blue color that is the hue of the area (Area 1).

  The area (Area 3a), the area (Area 3b), and the area (Area 4) are selected using the hue of the area (Area 3) selected using the hue-color tone palette 300 shown in FIG. ) Is corrected (step S204).

  As shown in FIG. 16, the pixel group constituting the area (Area 4) and the area (Area 3b) is displayed in “dark yellow green” having a color tone lower than the yellowish green color that is the hue of the area (Area 3). ) Are displayed in a “dark blue” color tone that is lower than the light blue color of the area (Area 1).

  As described above, it is possible to provide a comfortable environment for the viewer by reducing the readability of the telop data with respect to the video data.

  In addition, the telop data area is divided into correction areas in consideration of the hue pattern around the telop data, and each of the divided areas has a color tone lower than the hue detected in the telop data correction reference area. By using and correcting, it is possible to further reduce the readability of the telop data with respect to the video data as compared with the case where the telop data is corrected with a single hue.

  FIG. 17 is a diagram illustrating an example of a setting screen displayed on the display required for setting a mode for performing correction processing for reducing the readability of a telop for video data and a mode for not performing correction processing.

  On the display 13, a setting screen m1 for setting a mode for performing a correction process for reducing the readability of a telop / a mode for not performing a correction process is displayed.

  While viewing this setting screen m1, the user sets whether to enter a mode for performing correction processing for reducing the readability of the telop or not to enter a mode for not performing correction processing.

  FIG. 18 is a flowchart illustrating an example of a procedure for setting a mode for performing a correction process for reducing the readability of a telop for video data and a mode for not performing a correction process.

  The user looks at the setting screen m1 and selects and determines “Yes” in the setting screen m1, for example, when performing correction processing that lowers the readability of the telop. These operations are performed by a remote control operation by the user, for example.

  For example, when “Yes” is selected and determined in the setting screen m1 by operating the remote controller 14 by the user, for example, the remote controller 14 performs a correction process for reducing the readability of the telop for the video data in accordance with the user operation. The controller 10 transmits a command for setting a mode (step S300 Yes), and the controller 10 receives a command for setting a mode for performing correction processing for reducing the readability of the telop for video data, for example, transmitted from the remote controller 14. (Step S301).

  When the controller 10 receives a command for setting a mode for performing correction processing for reducing the readability of the telop for the video data in step S301, the controller 10 performs telop data processing on the signal generated by the decoding processing by the decoder unit 110. The decoder processing unit 110 is set so that the processing is performed by the unit 111 (step S302).

  On the other hand, when “NO” is selected and determined in the setting screen m1 by operating the remote controller 14 by the user, for example, the remote controller 14 corrects the telop readability of the video data in accordance with the user operation. The controller 10 transmits a command for setting a normal mode that does not perform (No in step S300), and the controller 10 sets a normal mode that does not perform correction processing that lowers the readability of the telop for video data transmitted from the remote controller 14, for example. A command for receiving is received (step S303).

  When the controller 10 receives a command for setting a normal mode that does not perform correction processing for reducing the readability of the telop for the video data in step S303, the controller 10 displays the signal generated by the decoding processing by the decoder unit 110. 13 is set in the decoder processing unit 110 so as to be output to 13 (step S304).

  In this way, only when the user wants to reduce the readability of the telop by setting the design so that it can be set whether or not to perform correction processing to lower the readability of the telop for the video data by remote control operation by the user, for example. It is possible to execute a correction process for reducing the readability of the telop.

  The present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
