[0113] FIG. 4 is a drawing illustrating the internal configuration of a vehicle display device according to one embodiment of the present disclosure.

[0114] Referring to the drawings, a vehicle display device (100) according to one embodiment of the present disclosure includes an image generating device (300) that includes a light output device (400 of FIG. 8) and outputs a projection image (LTa), a light reflecting unit (310) that reflects the projection image (LTa) from the image generating device (300), a screen (Scr) on which the projection image (LTa) reflected from the light reflecting unit (310) is projected on one surface, a film (359) attached on the screen (Scr), and a signal processing device (170).

[0115] Meanwhile, a signal processing device (170) in a vehicle display device (100) according to an embodiment of the present disclosure includes a signal processing device (170) that controls the image generation device (300) to be turned off in a first mode, and controls the image generation device (300) to operate in a second mode, while performing compensation processing on the color or transmittance or pattern of the film (359) to output a projection image (LTa) based on the compensation processing. Accordingly, the visibility of the interior display in the vehicle can be improved. In particular, the visibility of the projection image can be improved in the second mode.

[0116] The first mode at this time may be named display off mode or interior mode, and the second mode may be named display on mode.

[0117] Meanwhile, among the multiple displays (180a, 180b, 180h) of FIGS. 1 to 3, the second display (180b) may be an interior display that is in harmony with the interlay inside the vehicle.

[0118] For example, the second display (180b) may include an image generating device (300), a light reflector (310), and a film (359).

[0119] That is, the second display (180b) can operate in the display off mode or the interior mode in the first mode, and in the second mode, the interior mode is turned off and the display on mode is operated.

[0120] Accordingly, in the first mode, the second display (180b) is in harmony with the interlay inside the vehicle, and in the second mode, the visibility of the image of the second display (180b) can be improved.

[0121] Meanwhile, a vehicle display device (100) according to one embodiment of the present disclosure may further include a lens array (357) disposed between a screen (Scr) and a film (359). Accordingly, the straightness of a projection image passing through the film (359) can be improved.

[0122] Alternatively, the vehicle display device (100) according to one embodiment of the present disclosure may further include a lenticular lens disposed between the screen (Scr) and the film (359). Accordingly, the straightness of the projected image passing through the film (359) can be improved.

[0123] Figures 5a to 9b are drawings referred to in the description of Figure 4.

[0124] Figure 5a illustrates that the second display (180b) operates in the first mode, which is the display off mode or interior mode.

[0125] Referring to the drawing, the signal processing device (170) can turn off the image generating device (300) so that the second display (180b) is turned off, according to the first mode.

[0126] Accordingly, based on the color, transmittance, or pattern of the film (359) attached to the screen (Scr), the second display (180b) can be recognized, similar to the surroundings inside the vehicle, such as an interior film (510). Accordingly, the second display (180b) operates in interior mode.

[0127] Figure 5b illustrates that the second display (180b) operates in the second mode, the display on mode.

[0128] Referring to the drawing, the signal processing device (170) can turn on the image generating device (300) so that the second display (180b) is turned on according to the second mode.

[0129] At this time, in order to prevent visibility from being lowered due to the color, transmittance, or pattern of the film (359) attached to the screen (Scr), the signal processing device (170) according to one embodiment of the present disclosure compensates for the color, transmittance, or pattern of the film (359) and controls the output of a projection image (LTa) based on the compensation processing.

[0130] Specifically, the signal processing device (170) can perform compensation processing on the input image based on the transmittance or pattern information of the film (359) and control the image generating device (300) to output the compensated projection image (LTa).

[0131] Accordingly, the visibility of the vehicle's interior display can be improved. In particular, the visibility of the projected image in the second mode can be improved.

[0132] Meanwhile, the signal processing device (170) can control the ratio of the first color in the input image to be reduced and the ratio of the second color or third color different from the first color to be increased when the color of the film (359) is the first color. Accordingly, the visibility of the projected image can be improved.

[0133] For example, if the color of the film (359) is red, the signal processing device (170) can control the input image to reduce the proportion of red and increase the proportion of at least one of blue or green other than red. Accordingly, the visibility of the projected image can be improved.

[0134] As another example, if the color of the film (359) is green, the signal processing device (170) can control the input image to reduce the proportion of green and increase the proportion of at least one of blue or red, which is different from green. Accordingly, the visibility of the projected image can be improved.

[0135] As another example, if the color of the film (359) is blue, the signal processing device (170) can control the ratio of blue in the input image to be reduced and the ratio of at least one of green and red, which is different from blue, to be increased. Accordingly, the visibility of the projected image can be improved.

[0136] Meanwhile, the signal processing device (170) can control the brightness of the projection image to increase as the transmittance of the film (359) decreases.

[0137] For example, the signal processing device (170) can control the brightness of the input image to increase as the transmittance of the film (359) decreases, thereby increasing the brightness of the projection image (LTa) from the image generating device (300). Accordingly, the visibility of the projection image can be improved.

[0138] Meanwhile, the signal processing device (170) can perform signal processing on an input image using a compensation pattern for compensating for the pattern of the film (359) and control the output of a projection image (LTa) based on the compensation pattern.

[0139] For example, if the pattern of the film (359) is a grid pattern, the input image can be signal-processed using a reciprocal grid pattern to compensate for the grid pattern, and a projection image (LTa) based on the compensation pattern can be controlled to be output. Accordingly, the visibility of the projection image can be improved.

[0140] Meanwhile, the signal processing device (170) can control the second display (180b) to display a navigation screen (520) based on compensation processing by compensating the color, transmittance, or pattern of the film (359), as shown in the drawing, according to the second mode. Accordingly, the visibility of the second display (180b), which is an interior display within the vehicle, can be improved.

[0141] Meanwhile, the signal processing device (170) can control compensation processing in the second mode during night driving to be different from compensation processing in the second mode during day driving.

[0142] For example, since the illumination inside the vehicle is higher during daytime driving than during nighttime driving, the signal processing device (170) can control compensation processing in the second mode to be performed more during daytime driving than compensation processing in the second mode during nighttime driving.

[0143] For example, if the color of the film (359) is the first color, the signal processing device (170) can control the ratio of the first color in the input image to be reduced more during daytime driving than during nighttime driving, and to increase the ratio of the second color or third color different from the first color. Accordingly, the visibility of the interior display can be improved during daytime driving.

[0144] As another example, the signal processing device (170) can control the brightness of the projection image (LTa) to be increased more during daytime driving than during nighttime driving. Accordingly, the visibility of the interior display within the vehicle can be improved during daytime driving.

[0145] Figure 5c illustrates that the second display (180b) is partly off and partly on, which is the third mode.

[0146] Referring to the drawing, the signal processing device (170) can control a third mode to be performed in which some areas (Arn) of the screen (Scr) are turned off and other areas (Arm) of the screen (Scr) are turned on.

[0147] Specifically, the signal processing device (170) controls the image generation device (300) to operate for another area (Arm) of the screen (Scr) when performing the third mode, and can control the color or transmittance or pattern of the film (359) to be compensated for so that a projection image (LTa) based on the compensation processing is output. Accordingly, the visibility of the projection image can be improved for another area (Arm) of the screen (Scr).

[0148] Meanwhile, some areas (Arn) of the screen (Scr) can be recognized, similar to the surroundings of the interior of the vehicle, such as an interior film (540).

[0149] For example, the signal processing device (170) can control the screen (Scr) area closer to the driver (Arm) among the driver and passenger areas to be turned on, and the screen (Scr) area closer to the passenger area (Arn) to be turned off. Accordingly, the visibility of the projected image can be improved.

[0150] Meanwhile, the signal processing device (170) can control the navigation screen to be displayed in another area (Arm) of the screen (Scr), such as the drawing k. Accordingly, visibility can be improved.

[0151] Fig. 6a is a drawing illustrating a case where a film (359) is attached to a screen, and Fig. 6b is a drawing referenced in the description of Fig. 6a.

[0152] Referring to the drawings, a vehicle display device (100x) related to the present disclosure may include an image generating device (300x) that outputs a projection image, a screen (Scr) on which the projection image is projected on one side, a film (359) attached on the screen (Scr), and a signal processing device (170x) that outputs an image signal to the image generating device (300x).

[0153] Meanwhile, in the case where only the film (359) attached to the screen (Scr) is attached, the visibility of the projected image may be reduced due to interference, etc., due to the pattern inside the film (359).

[0154] In particular, this visibility degradation occurs when the signal processing device (170x) within the vehicle display device (100x) does not perform separate compensation.

[0155] That is, as shown in Fig. 6b, when a projection image (610) output from an image generating device (300x) passes through a pattern (620) in a film (359), it is recognized as a projection image (630) with reduced visibility.

[0156] Accordingly, in order to prevent such degradation of visibility, as described in FIG. 4, the signal processing device (170) controls the image generation device (300) to be turned off in the first mode, and controls the image generation device (300) to operate in the second mode, while controlling the color or transmittance or pattern of the film (359) to be compensated for so that a projection image based on the compensation processing is output.

[0157] In addition, in order to prevent such degradation of visibility, the vehicle display device (100) is further provided with a lens array or a lenticular lens.

[0158] FIG. 7A illustrates an example of the internal configuration of a vehicle display device according to one embodiment of the present disclosure.

[0159] Referring to the drawings, a vehicle display device (100) according to one embodiment of the present disclosure may include a signal processing device (170) that outputs an image signal, an image generating device (300) that outputs a projection image based on the image signal, a screen (Scr) on which a projection image (LTa) is projected on one surface, a film (359) attached on the screen (Scr), and a lens array (357) or lenticular lens disposed between the screen (Scr) and the film (359).

[0160] By means of a lens array (357) or lenticular lens placed between the screen (Scr) and the film (359), the straightness of light passing through the film (359) is improved despite the pattern inside the film (359), and thus visibility can be improved.

[0161] Figure 7b is a drawing referenced in the description of Figure 7a.

[0162] Referring to the drawing, the signal processing device (170) in the vehicle display device (100) according to one embodiment of the present disclosure outputs an image signal in which the color or transmittance or pattern of the film (359) is compensated for in the display on mode, which is the second mode.

[0163] That is, the signal processing device (170) outputs a compensation image (615) that compensates for the color, transmittance, or pattern of the film (359) based on the input image (610), and the image generating device (300) can output a projection image based on the compensation image (615).

[0164] And, when the projection image based on the compensation image (615) passes through the pattern (620) in the film (359), it is recognized as a projection image (640) with no degradation in visibility.

[0165] Accordingly, the visibility of the vehicle's interior display can be improved. In particular, the visibility of the projected image in the second mode can be improved.

[0166] Fig. 8 is an example of an internal block diagram of the vehicle display device of Fig. 4.

[0167] Referring to the drawings, a vehicle display device (100) according to an embodiment of the present disclosure includes a signal processing device (170), an image generating device (300), a light reflecting portion (310), a screen (Scr), and a film (359) attached on the screen (Scr).

[0168] The signal processing device (170) can output an image signal to the image generating device (300).

[0169] Meanwhile, the projection image (LTa) output from the image generating device (300) can be reflected from the light reflecting portion (310).

[0170] Meanwhile, the vehicle display device (100) according to the embodiment of the present disclosure may further include an external light sensor (711), an internal light sensor (713), or a user input unit (110).

[0171] The signal processing device (170) can vary the compensation processing for the color, transmittance, or pattern of the film (359) based on the external illuminance (Cso) from the external illuminance sensor (711), the internal illuminance (Csi) from the internal illuminance sensor (713), or the setting input (Csp) from the user input unit (110).

[0172] For example, the signal processing device (170) can control the light transmittance of the first projection image (LTa) to decrease as the external illuminance (Cso) increases.

[0173] As another example, the signal processing device (170) can control the brightness of the projected image to increase as the internal illuminance (Csi) decreases. Accordingly, the visibility of the projected image can be improved.

[0174] As another example, the signal processing device (170) can control the brightness of the projected image to increase as the brightness setting according to the setting input (Csp) increases. Accordingly, the visibility of the projected image can be improved.

[0175] Meanwhile, the signal processing device (170) can control the brightness of the projected image to increase as the difference between the external illumination outside the vehicle (200) and the internal illumination of the vehicle (200) increases. Accordingly, the visibility of the projected image can be improved.

[0176] Meanwhile, the image generation device (300) includes an optical output device (400) for optical output.

[0177] Meanwhile, the light output device (400) may include a light source (309) and a digital mirror device (308) that reflects light output from the light source (309).

[0178] For example, the light source (309) may include an LED diode or a laser diode.

[0179] Meanwhile, the digital mirror device (308) may be equipped with a plurality of digital mirrors. For example, it may be equipped with a digital micromirror device (DMD).

[0180] Meanwhile, the image generation device (300) may further include a digital mirror control unit (305) for controlling a digital mirror device (308) and a light source control unit (306) for controlling a light source (309).

[0181] In particular, the image generation device (300) has a processor (370), and the processor (370) may include a digital mirror control unit (305) for controlling a digital mirror device (308) and a light source control unit (306) for controlling a light source (309).

[0182] Meanwhile, the signal processing device (170) may be equipped with an image generation control unit (173) for controlling the image generation device (300) and a compensation control unit (174) for compensating the color, transmittance, or pattern of the film (359).

[0183] Meanwhile, the image generation control unit (173) and the compensation control unit (174) may be provided within the processor (175) within the signal processing device (170).

[0184] Meanwhile, the compensation control unit (174) can control, in the second mode, to output a projection image (LTa) based on compensation processing by compensating the color, transmittance, or pattern of the film (359).

[0185] For example, in the second mode, the compensation control unit (174) can perform compensation processing on the input image based on the transmittance or pattern information of the film (359).

[0186] Meanwhile, the compensation control unit (174) can control, in the second mode, to reduce the ratio of the first color in the input image when the color of the film (359) is the first color, and to increase the ratio of the second color or third color that is different from the first color.

[0187] Meanwhile, the compensation control unit (174) can control the brightness of the projection image (LTa) to increase as the transmittance of the film (359) decreases in the second mode.

[0188] Meanwhile, the compensation control unit (174) can signal-process the input image using a compensation pattern for compensating the pattern of the film (359) in the second mode.

[0189] Meanwhile, the compensation control unit (174) can control the compensation processing in the second mode during night driving and the compensation processing in the second mode during day driving to be different.

[0190] In particular, the compensation control unit (174) can control the compensation processing in the second mode to be performed more during daytime driving than during night driving in the second mode.

[0191] Meanwhile, the signal processing device (170) may perform operation control of the digital mirror device (308) or operation control of the light source (309) based on external illuminance (Cso) from the external illuminance sensor (711), internal illuminance (Csi) from the internal illuminance sensor (713), or setting input (Csp) from the user input unit (110).

[0192] For example, the signal processing device (170) can control the brightness of the projection image to become higher for each frame as the external illuminance (Cso) increases.

[0193] As another example, the signal processing device (170) can control the brightness of the projection image to increase on a frame-by-frame basis as the internal illuminance (Csi) increases.

[0194] FIG. 9a is another example of an internal block diagram of the vehicle display device of FIG. 4.

[0195] Referring to the drawings, a vehicle display device (100b) according to an embodiment of the present disclosure is similar to the vehicle display device (100) of FIG. 8, but differs in that an image format change unit (302) is further provided within the image generation device (300b). The differences will be described below.

[0196] The image generation device (300b) outputs a projection image based on an input image from an external input or an input image from a signal processing device (170).

[0197] At this time, the image format change unit (302) in the image generation device (300b) can change the image format of an input image from an external input or an input image from a signal processing device (170).

[0198] For example, when the frame rate of the input image is the first frame rate, the image generation device (300b) can control the frame rate to be varied to become the second frame rate.

[0199] Specifically, the image generation device (300b) can increase the frame rate to vary it to 120 Hz when the frame rate of the input image is 60 Hz.

[0200] Meanwhile, the image format change unit (302) may be provided within the processor (370).

[0201] Meanwhile, according to FIG. 9a, in the second mode, the signal processing device (170) outputs a compensation image (615) that compensates for the color, transmittance, or pattern of the film (359) based on the input image (610), and the image generating device (300) can output a projection image (LTa) based on the compensation image (615).

[0202] And, when the projection image (LTa) based on the compensation image (615) passes through the pattern (620) in the film (359), it is recognized as a projection image (640) with no degradation in visibility.

[0203] FIG. 9b is a drawing for reference in explaining the operation of the third mode of the vehicle display device of FIG. 4.

[0204] Referring to the drawing, the signal processing device (170) in the vehicle display device (100b) according to the embodiment of the present disclosure can, in the third mode, control some areas to be turned off like the first mode and other areas to be compensated like the second mode, based on the input image (610).

[0205] That is, as shown in the drawing, a partial compensation image (615b) is output in which the color or transmittance or pattern of the film (359) is partially compensated, and the image generation device (300) can output a projection image based on the partial compensation image (615b).

[0206] And, when a projection image based on some compensation image (615b) passes through a pattern (620) in the film (359), some areas are recognized as an interlay film and other areas are recognized as some projection images (640b) with no degradation in visibility.

[0207] FIG. 12a illustrates an example of the internal configuration of a vehicle display device according to another embodiment of the present disclosure.

[0208] Referring to the drawings, a vehicle display device (100m) according to another embodiment of the present disclosure includes a signal processing device (170) that outputs an image signal, a panel (210) that displays an image based on the image signal, and a film (359) attached on the panel (210).

[0209] Meanwhile, the panel (210) may be a liquid crystal panel, an LED panel, or an OLED panel.

[0210] Meanwhile, the signal processing device (170) controls the panel (210) to be turned off in the first mode, and controls the panel (210) to operate in the second mode, but controls the color or transmittance or pattern of the film (359) to be compensated so that an output image based on the compensation processing is output.

[0211] Accordingly, the visibility of the vehicle's interior display can be improved. In particular, the visibility of the output image in the second mode can be improved.

[0212] Meanwhile, a vehicle display device (100m) according to another embodiment of the present disclosure may further include a lens array (357) or lenticular lens disposed between the panel (210) and the film (359).

[0213] By means of a lens array (357) or a lenticular lens placed between the panel (210) and the film (359), the straightness of light passing through the film (359) is improved despite the pattern inside the film (359), and thus visibility can be improved.

[0214] Meanwhile, the signal processing device (170) can perform compensation processing on the input image based on the transmittance or pattern information of the film (359) and control the panel (210) to output the compensated output image.

[0215] Meanwhile, the signal processing device (170) can control the ratio of the first color among the input images to be reduced and the ratio of the second color or third color different from the first color to be increased when the color of the film (359) is the first color.

[0216] For example, if the color of the film (359) is red, the signal processing device (170) can control the ratio of red in the input image to be reduced and the ratio of at least one of blue or green other than red to be increased. Accordingly, the visibility of the output image can be improved.

[0217] Meanwhile, the signal processing device (170) can control the brightness of the output image to increase as the transmittance of the film (359) decreases.

[0218] For example, the signal processing device (170) can control the brightness of the output image to increase as the transmittance of the film (359) decreases. Accordingly, the visibility of the output image can be improved.

[0219] Meanwhile, the signal processing device (170) can perform signal processing on an input image using a compensation pattern for compensating for the pattern of the film (359) and control the output image to be output based on the compensation pattern.

[0220] For example, if the pattern of the film (359) is a grid pattern, the input image can be signal processed using a reciprocal grid pattern to compensate for the grid pattern, and an output image based on the compensation pattern can be controlled to be output. Accordingly, the visibility of the output image can be improved.

[0221] Meanwhile, the signal processing device (170) can control compensation processing in the second mode during night driving to be different from compensation processing in the second mode during day driving. Accordingly, the visibility of the output image can be improved.

[0222] Meanwhile, the signal processing device (170) can control compensation processing in the second mode to be performed more frequently during daytime driving than during nighttime driving. Accordingly, the visibility of the output image can be improved.

[0223] For example, since the illumination inside the vehicle is higher during daytime driving than during nighttime driving, the signal processing device (170) can control compensation processing in the second mode to be performed more during daytime driving than compensation processing in the second mode during nighttime driving.

[0224] Figure 12b is a drawing referenced in the description of Figure 12a.

[0225] Referring to the drawing, a signal processing device (170) in a vehicle display device (100m) according to another embodiment of the present disclosure outputs an image signal in which the color or transmittance or pattern of the film (359) is compensated for in the display on mode, which is the second mode.

[0226] That is, the signal processing device (170) can output a compensation image (615m) in which the color, transmittance, or pattern of the film (359) is compensated based on the input image (610m).

[0227] And, when the output image based on the compensation image (615m) passes through the pattern (620m) in the film (359), it is recognized as an output image (640m) with no degradation in visibility.

[0228] Accordingly, the visibility of the vehicle's interior display can be improved. In particular, the visibility of the output image in the second mode can be improved.

[0229] Fig. 13 is an example of an internal block diagram of the vehicle display device of Fig. 12a.

[0231] The signal processing device (170) can output a video signal to the panel (210).

[0232] Meanwhile, according to FIG. 13, in the second mode, the signal processing device (170) can output a compensation image (615m) in which the color, transmittance, or pattern of the film (359) is compensated based on the input image (610m).

[0233] And, when the output image based on the compensation image (615m) is displayed on the panel (210) and passes through the pattern (620m) in the film (359), it is recognized as an output image (640m) with no degradation in visibility.

[0234] Meanwhile, the vehicle display device (100m) according to the embodiment of the present disclosure may further include an external light sensor (711), an internal light sensor (713), or a user input unit (110).

[0235] The signal processing device (170) can vary the compensation processing for the color, transmittance, or pattern of the film (359) based on the external illuminance (Cso) from the external illuminance sensor (711), the internal illuminance (Csi) from the internal illuminance sensor (713), or the setting input (Csp) from the user input unit (110).

[0236] For example, the signal processing device (170) can control the brightness of the output image to increase as the external illuminance (Cso) increases.

[0237] As another example, the signal processing device (170) can control the brightness of the output image to increase as the internal illuminance (Csi) decreases. Accordingly, the visibility of the output image can be improved.

[0238] As another example, the signal processing device (170) can control the brightness of the output image to increase as the brightness setting according to the setting input (Csp) increases. Accordingly, the visibility of the output image can be improved.

[0239] Meanwhile, the signal processing device (170) can control the brightness of the output image to increase as the difference between the external illumination outside the vehicle (200) and the internal illumination of the vehicle (200) increases. Accordingly, the visibility of the output image can be improved.

[0240] Meanwhile, the signal processing device (170) may be equipped with a panel control unit (173b) for controlling the panel (210) and a compensation control unit (174) for compensating the color, transmittance, or pattern of the film (359).

[0241] Meanwhile, the panel control unit (173b) and the compensation control unit (174) may be provided within the processor (175) within the signal processing device (170).

[0242] Meanwhile, the compensation control unit (174) can control the output image based on the compensation processing by compensating the color, transmittance, or pattern of the film (359) in the second mode.

[0243] For example, in the second mode, the compensation control unit (174) can perform compensation processing on the input image based on the transmittance or pattern information of the film (359).

[0244] Meanwhile, the compensation control unit (174) can control, in the second mode, to reduce the ratio of the first color in the input image when the color of the film (359) is the first color, and to increase the ratio of the second color or third color that is different from the first color.

[0245] Meanwhile, the compensation control unit (174) can control the brightness of the output image to increase as the transmittance of the film (359) decreases in the second mode.

[0246] Meanwhile, the compensation control unit (174) can signal-process the input image using a compensation pattern for compensating the pattern of the film (359) in the second mode.

[0247] Meanwhile, the compensation control unit (174) can control the compensation processing in the second mode during night driving and the compensation processing in the second mode during day driving to be different.

[0248] In particular, the compensation control unit (174) can control the compensation processing in the second mode to be performed more during daytime driving than during night driving in the second mode.

[0249] Meanwhile, the signal processing device (170) may perform operation control of the panel (210) based on external illuminance (Cso) from an external illuminance sensor (711), internal illuminance (Csi) from an internal illuminance sensor (713), or setting input (Csp) from a user input unit (110).

[0250] For example, the signal processing device (170) can control the brightness of the output image of the panel (210) to become higher for each frame as the external illuminance (Cso) increases.

[0251] As another example, the signal processing device (170) can control the brightness of the output image of the panel (210) to increase on a frame-by-frame basis as the internal illuminance (Csi) increases.

[0252] Fig. 14 is a drawing for reference in explaining the operation of the third mode of the vehicle display device of Fig. 12a.

[0253] Referring to the drawing, the signal processing device (170) in the vehicle display device (100mb) according to the embodiment of the present disclosure can be controlled to perform a third mode in which some areas of the panel (210) are turned off and other areas of the panel (210) are turned on.

[0254] For example, in the third mode, the signal processing device (170) can control, based on the input image (610m), some areas to be turned off like the first mode and other areas to be compensated like the second mode.

[0255] Meanwhile, the signal processing device (170) can control the panel (210) to operate in other areas of the panel (210) when performing the third mode, and can control the color, transmittance, or pattern of the film (359) to be compensated for so that an output image based on the compensation processing is output. Accordingly, the visibility of the output image can be improved.

[0256] Meanwhile, the signal processing device (170) can control the panel (210) to turn on an area of ​​the panel (210) closer to the driver among the driver and passengers, and to turn off an area of ​​the panel (210) closer to the passengers. Accordingly, the visibility of the output image can be improved.

[0258] Meanwhile, the signal processing device (170) can output a partially compensated image (615bm) in which the color, transmittance, or pattern of the film (359) is partially compensated, as shown in the drawing.

[0259] And, when an output image based on a partial compensation image (615bm) is displayed on the panel (210) and passes through a pattern (620m) within the film (359), some areas are recognized as an interlay film, and other areas are recognized as a partial output image (640bm) with no degradation in visibility. Accordingly, the visibility of the output image can be improved in the second mode.
