[0020]   In addition, the above-mentioned letter box type video signal with an aspect ratio of 16: 9 is When using the same display method as when displaying a video signal with an aspect ratio of 4: 3 Is displayed above and below the main image portion 41a, which is an area showing a video, as shown in FIG. , As an image provided with the non-image part 42, 42 which is a black area where the image is not displayed Is displayed.

[0021]   Explaining the television section 2 in detail, the tuner 14 is controlled by the control means 4. The video signal obtained by receiving the commercial broadcast of the indicated channel is transmitted to the television circuit IC7. Output to. The drive circuit 8 is from the video signal processing circuit 21 of the television circuit IC7. The three primary color signals sent out are amplified to drive the cathode of the CRT 9. CR T9 has a small display surface size of 10 inches and its aspect ratio is It is 4: 3.

[0022]   The vertical output circuit 11 outputs the vertical signal output from the deflection signal circuit 22 of the television circuit IC7. The direct deflection drive signal is amplified to drive the deflection coil 10 of the CRT 9. Horizontal The drive circuit 12 increases the horizontal deflection drive signal sent from the deflection signal circuit 22. The width is driven to drive the horizontal output circuit 13. The horizontal output circuit 13 is the horizontal drive circuit 1 The output of 2 is amplified and the deflection coil 10 is driven. Also, apply a high voltage to CRT9. (This route is not shown).

[0023]   The television circuit IC7 integrally includes a video signal processing circuit 21 and a deflection signal circuit 22. This is an integrated IC, and the functions (tuners) required for the circuits of television receivers. It is an IC that executes most of the functions of Therefore, the video signal processing The path 21 receives the video signal from the DVD reproducing section 1 or Alternatively, the video signal from the tuner 14 is switched and input. And switch on Three primary color signals are generated from the input video signal and output to the drive circuit 8.

[0024]   The deflection signal circuit 22 drives the vertical deflection from the switched and input video signal. A signal is generated and sent to the vertical output circuit 11, and a signal for horizontal deflection is generated. To the horizontal drive circuit 12. The deflection signal circuit 22 is a vertical output circuit. The amplitude of the drive signal for vertical deflection given to 11 is compared with the command from the control means 4. Change the amplitude to suit.

[0025]   The input unit 5 includes a plurality of keys provided on a front panel (not shown) of the apparatus body. Equipped with a switch and a light receiving circuit for receiving infrared rays from the remote controller 6 It is a block. Also, key switches on the front panel and remote control When the user's instruction is input to the controller 6, the input instruction is sent to the control means 4. .

[0026]   The control means 4 is composed of a microcomputer, and is a DVD reproducing device. Controls the main operation of the integrated television receiver. That is, the DVD reproducing unit 1 Control the behavior of. It also controls the operation of the television section 2.

[0027]   In controlling the operation of the DVD reproducing unit 1, the DVD reproducing unit 1 reproduces and outputs. Whether the input video signal has an aspect ratio of 4: 3, or 1 Aspect ratio information indicating whether the video signal is a 6: 9 letterbox format is D Read from the VD playback unit 1 (DVD playback unit 1 sends the aspect ratio information to the control means 4) To send).

[0028]   Further, in controlling the operation of the television section 2, a command given to the television circuit IC7 is given. Of the vertical deflection that the deflection signal circuit 22 sends to the vertical output circuit 11 Control the signal level. That is, it supports video signals with an aspect ratio of 4: 3 2 is displayed, the deflection signal circuit 22 is set to the vertical output circuit as shown in FIG. The level of the drive signal 31 sent to 11 is L1. Meanwhile, letterbox When the display is compatible with the video signal of the system, the level of the drive signal 31 is set to L. Set to 2. As a result, the deflection width of vertical deflection in the CRT 9 has an aspect ratio of 4 : In the case of 3 video signals, the normal deflection width is used, and letterbox type video signals In the case of, the deflection width for enlargement, which is the deflection width enlarged in the vertical direction from the deflection width for normal, Become.

[0029]   When an instruction to stop enlargement is input to the remote controller 6, the When the pect ratio information indicates that the video signal is a letterbox type Also, the control means 4 sets the deflection width in the vertical deflection of the CRT 9 to the normal deflection width. It

[0030]   Here, referring to FIG. 3, when the deflection width in the vertical deflection becomes the normal deflection width. Difference in the display of the letterbox type video signal between the The difference will be described.

[0031]   FIG. 3 (A) shows that when the deflection width is set to the normal deflection width, 7 shows a display surface of the CRT 9 when displaying a video signal of a scanning system. At this time Is about 75% of the width H2 of the main image portion 41a with respect to the width H1 of the display surface in the vertical direction. It has become. On the other hand, (B) shows that the deflection width is set to the enlargement deflection width. , Shows the display surface of the CRT 9 when displaying a letterbox type video signal. It At this time, the main image portion 41b is enlarged in the vertical direction, so that the vertical deflection is prevented. The width H3 of the main image portion 41b is about 90% of the width H1 of the display surface.

[0032]   The ratio of the width H3 of the main image portion 41b to the width H1 of the display surface is 90 %, But other ratios should be in the range of 85% to 95% Good This is because when the ratio is 85% or less, the enlargement ratio is small and the main image portion 41b is small. This is because it will be difficult to see.

[0033]   Further, if the ratio is made larger than 95%, the deflection signal circuit 22 of the television circuit IC7 The ratio of the drive signal output to the vertical output circuit 11 becomes 95%. Even when set as above, due to variations in individual devices, the The rate may exceed 100%. Therefore, in the production line, The frame to be set in the deflection signal circuit 22 so that the ratio of the display surface does not exceed 100%. It becomes necessary to adjust the band value, which complicates the production process. Also, in the actual display , Even if the situation does not exceed 100%, the ratio exceeds 95% And the image is enlarged too much in the vertical direction, and the distortion of the image becomes noticeable. Cause

[0034]   From the above, the width H3 of the main image portion 41b with respect to the width H1 of the display surface is 95% or less. In the case of making it small, it is not necessary to adjust the command value in the production process. Also, vertically It is possible to suppress the distortion of the image caused by the enlargement only to the inconspicuous range. it can.

[0035]   FIG. 4 is a flowchart showing a main operation when reproducing the DVD 3. The operation of the embodiment will be described with reference to FIG.

[0036]   When the DVD 3 to be played back is set, the DVD playback unit 1 displays the DV The various information recorded in D3 is read and stored internally. Information read at this time According to the report, the video signal recorded on DVD3 has a turbo ratio of 16: 9. Video signal of the X. system or an image signal with an aspect ratio of 4: 3 Is included (step S1).

[0037]   When the DVD reproducing unit 1 is caused to reproduce the DVD 3, the control means 4 reproduces the DVD. The aspect ratio information output from the unit 1 is read (step S2). And read If the extracted aspect ratio information indicates 16: 9 (letterbox method If the video signal is a video signal of a formula), the control means 4 controls the remote controller 6 It is checked whether the instruction from is to stop the enlargement (steps S3 and S4). ). If the enlargement is not stopped, the control means 4 sends a command to the deflection signal circuit 22. By sending the control signal from the deflection signal circuit 22 to the vertical output circuit 11. The level of the live signal is changed from the level L1 corresponding to the normal deflection width to the enlargement deflection width. Is changed to the level L2 corresponding to (step S5).

[0038]   As a result of the above operation, on the CRT 9, the displayed image is enlarged vertically. It Therefore, in the normal deflection width, the vertical direction on the display surface of the CRT 9 The main image portion 41a having a width ratio of 75% (H2) has a width ratio in the vertical direction. The image 41b with 90% (H3) is displayed on the CRT 9.

[0039]   On the other hand, the aspect ratio information read in step S2 indicates that the aspect ratio is Even if the video signal of 16: 9 is displayed, the remote controller is operated by the user. When the instruction input to 6 is the stop of the enlargement, the control means 4 performs the operation. From step S4 to step S6, the deflection width in vertical deflection is set to the normal deflection width. Keep it. Therefore, the image in the main image area is not enlarged vertically. It is displayed as 41a.

[0040]   Also, when the DVD reproducing unit 1 is made to perform reproduction, it is output from the DVD reproducing unit 1. When the aspect ratio information indicates that the video signal has an aspect ratio of 4: 3, The operation moves from step S3 to step S6. Therefore, the aspect ratio The 4: 3 video signal is to be displayed on the entire display surface of the CRT 9. It

[0041]   To give a supplementary explanation here, the operation of step S5 causes the image to be vertically displayed. Even when the image is enlarged, the image distortion and coarse As the CRT 9 is as small as 10 inches, it is not very noticeable and the image is enlarged. The effect of improving visibility is greater. In addition, the effects described above are Almost the same can be obtained when 9 is 14 inches in size.

[0042]

[Effect of device]

  As described above, in the present invention, the size ranges from 9 inches to 14 inches. Equipped with a CRT with an aspect ratio of 4: 3, the command is sent to the TV circuit IC. Therefore, in the configuration in which the deflection width in the vertical deflection can be changed, the DVD The aspect ratio information indicates that the playback section is a letterbox type video signal. When shown, the deflection width in vertical deflection is expanded in the vertical direction from the normal deflection width. The deflection width for enlargement, which is the deflection width, is set. Also expanded to remote controllers When the stop is input, the DVD playback unit must have an aspect ratio of 16: 9. The aspect ratio of the video displayed on the CRT when sending aspect ratio information indicating The expansion of the direction has stopped. In addition, when the deflection width is set to the enlargement deflection width, the vertical Of the letterbox type video signal in the display area of the CRT The ratio of the display width of the main image part is set in the range of 85% to 95%. Because of this, hard When the video signal is letterbox type without increasing the wear, The video signal can be expanded vertically and displayed on the CRT, and the production line In, it is not necessary to adjust the enlargement ratio in the vertical direction. And also the turbo Effect obtained by vertically expanding the X-type video signal in the vertical direction Can overcome the drawbacks such as screen distortion, and The expansion can be stopped when the expansion in the direction is not desired.

[0043]   Further, in the present invention, a CRT having an aspect ratio of 4: 3 is provided, and a television circuit IC is provided. Command to give a configuration in which the deflection width in vertical deflection can be changed. Aspect that the DVD playback unit is a letterbox type video signal When shown by the ratio information, the deflection width in vertical deflection is set to be longer than the normal deflection width. The deflection width for enlargement, which is the deflection width enlarged in the direction, is set. For this reason, When the video signal is letterbox type without causing increase of air, The image signal can be enlarged in the vertical direction and displayed on the CRT.

[0044]   In addition, when the deflection width is set to the enlargement deflection width, , Display width of main picture part of letterbox type video signal in display area of CRT The ratio is set in the range of 85% to 95%. Therefore, the image is small and difficult to see It is prevented from becoming a thing. Also, since the ratio is less than 95%, Actual ratio in display exceeds 100% even when the device varies. Never. For this reason, production can be performed without sacrificing the effect of making images easier to see. It is possible to eliminate the need to adjust the enlargement factor in the vertical direction on the line.

[0045]   In addition, the size of the CRT is limited to 9 inches to 14 inches. It Therefore, even when the image is enlarged vertically, it is enlarged only by vertical deflection. The distortion and roughness of the image caused by the image is not very noticeable due to the small size of the CRT. The effect of improving legibility is greater due to the enlargement. Because of this, Effect obtained by vertically expanding the X-type video signal in the vertical direction Can outweigh defects such as image distortion.
