<Embodiment 1>
FIG. 1 is a configuration diagram illustrating a display device 100 according to the first embodiment.

  As shown in FIG. 1, the display device 100 includes an image signal processing unit 1, a display unit 2, a connector 3, a control unit 4, and an OSD processing unit 5. The display device 100 is connected to an image signal source 200 such as a computer and a sensor 300.

  The image signal input from the image signal source 200 to the display device 100 is processed by the image signal processing unit 1 and then displayed as an image on the display unit 2. In addition, on this image, the OSD processing unit 5 displays an OSD for adjusting settings such as luminance in an overlapping manner.

  The display content on the display unit 2 is read by the sensor 300 by a user operation as described later. An output signal of the sensor 300 is input from the connector 3 to the display device 100. That is, the connector 3 functions as an interface unit for connecting the sensor.

  An output signal of the sensor 300 input from the connector 3 is input to the control unit 4. The control unit 4 identifies the reading content of the sensor 300 based on the input signal, controls the image signal processing unit 1 and the OSD processing unit 5, and performs setting adjustment such as luminance in the image display unit 2.

  FIG. 2 shows the display of OSD 6 in the display device 100 and the connection between the display device 100 and the sensor 300. The OSD 6 for adjustment is displayed on the display unit 2 disposed on the front surface of the display device 100 so as to overlap a part of the displayed image. The display device 100 and the sensor 300 are connected by a cable 7.

  FIG. 3A shows an example of the OSD 6 for adjusting the brightness (contrast). The OSD 6 displays a plurality of options to be selected by the user (here, two to increase or decrease the contrast). That is, an area 8 corresponding to an option that has a higher brightness than the current brightness and that increases the brightness and an area 9 that has a lower brightness than the current brightness and corresponds to the option that decreases the brightness are displayed.

  Next, the procedure of the brightness adjustment by the user operation will be described with reference to FIGS.

  First, as shown in FIG. 2, the user connects the cable 7 connected to the sensor 300 to the connector 3 of the display device 100. At this time, in FIG. 1, the control unit 4 detects that the sensor 300 is connected via the connector 3 and controls the image signal processing unit 1 and the OSD processing unit 5 as shown in FIG. 2. Then, the OSD 6 is displayed over the image on the display unit 2.

  Next, the user selects one of the options on the OSD 6 displayed as shown in FIG. For example, when increasing the brightness, the sensor 300 is brought into contact with the region 8 of the display unit 2. An output signal from the sensor 300 is input to the control unit 4 shown in FIG. The control unit 4 identifies that the region 8 has been selected by comparing the luminance detected by the input signal with a predetermined threshold value. Then, the luminance of the display unit 2 is increased by controlling the image signal processing unit 1 and the OSD processing unit 5. Thereby, the brightness adjustment of the display device 100 is performed by a user operation. Further, when it is detected that the sensor 300 has been removed via the connector 3, the OSD 6 shown in FIGS.

  Here, the above options are not limited to two, and may be three or more. For example, by setting N threshold values as described above, it is possible to set N + 1 options.

  In addition, the choice display such as the luminance in the regions 8 and 9 may change with time. By changing the options over time, many options can be displayed on the display unit 2 even when the space for displaying the OSD 6 is small. Alternatively, even when only one threshold value is set, it is possible to provide a plurality of options by combining them by temporally changing the brightness of each region.

  Further, this option is not limited to the luminance, but may be related to the setting of the display device 100. For example, any adjustment item such as the screen position (position) and size as shown in FIG. When there are a plurality of adjustment items, the user may select one using the sensor 300 in advance in the OSD displaying the plurality of adjustment items as shown in FIG.

  Further, the parameter measured by the sensor 300 is not limited to the luminance, and for example, a sensor that measures R, G, and B colors may be used. By simultaneously displaying a plurality of parameters such as luminance and color as parallel data, a plurality of options can be provided. Alternatively, the interval between flickers may be used instead of the brightness and color. Furthermore, a sensor 300 that can recognize the shape of the image, characters, and the like may be used.

  As the sensor 300, a sensor capable of non-contact detection may be used. Thereby, since remote control is possible, the freedom degree of the installation place of the display apparatus 100 can be raised.

  Further, as the sensor 300, an existing sensor that is generally used may be used. By using an existing sensor, the cost can be reduced.

  Further, as shown in FIG. 4, a wireless line 10 using infrared rays or radio waves may be used instead of the cable 7. In this case, the display device 100 includes a light receiving unit 11 for receiving infrared rays or the like instead of the connector 3, and the OSD 6 is displayed on the display unit 2 when the power of the sensor 300 is turned on. Thereby, since the cable 7 can be made unnecessary, the operability of the sensor 300 can be improved.

  Thus, in the display device 100 according to the present embodiment, setting adjustment by the OSD 6 is performed using the sensor 300 instead of the button, so there is no need to install a button on the display device 100. Therefore, the setting can be adjusted by a simple operation while increasing the degree of freedom of design.

<Embodiment 2>
In the first embodiment, setting adjustment by a user operation after shipment has been described. In the second embodiment, a system for inspecting quality and the like in a production line before shipment will be described.

  FIG. 5 is a configuration diagram illustrating the display device 101 according to the second embodiment.

  In FIG. 5, a stationary sensor 301 or the like that is automatically operated on the production line is used instead of the sensor 300 of FIG. 1 that is operated by the user. An output signal from the sensor 301 is not input to the display device 101 but is input to an inspection device 400 that is an inspection unit including a computer or the like installed outside the display device 101. Therefore, unlike the display device 100 shown in FIG. 1, the display device 101 does not need to incorporate the connector 3 for sensor connection. The display device 101 includes the same elements as those of the display device 100 except for the connector 3. In FIG. 5, elements similar to those in FIG. 1 are denoted by the same reference numerals, and detailed description thereof is omitted here. Also, in the following description of the operation, detailed description of the same operation as in the first embodiment is omitted.

  In FIG. 5, the control unit 4 controls the image processing unit 1 and the OSD processing unit 5 in accordance with a display device inspection program stored in advance, and displays the OSD 6 on the display unit 2. An output signal from the sensor 301 is input to the inspection apparatus 400. The inspection apparatus 400 automatically detects the brightness of the OSD 6 based on the input signal. Then, the normality of this signal is confirmed according to the inspection program stored in advance in the inspection apparatus. Thereby, according to the inspection program stored in advance in the display device 101 and the inspection device 400, the display device 101 can be automatically inspected on the production line.

  Thus, in the inspection system according to the present embodiment, the inspection is performed by detecting the OSD 6 displayed on the display unit 2 by the sensor 301 in accordance with the inspection program stored in advance. Accordingly, automatic inspection of the display device 101 on the production line is possible.

  In the above description, the automatic inspection is performed by detecting the brightness of the OSD 6 displayed on the display unit 2. However, the automatic inspection is not limited to the OSD 6 and is displayed on the display unit 2 in accordance with a pre-stored inspection program. Anything is acceptable. For example, as in the display device 102 shown in FIG. 6, an image signal input from the image signal source 200 is displayed on the display unit 2, and the image itself (without the OSD 6 overlaid) is read by the sensor 301. Good. In this case, the display device 102 does not need to have the OSD processing unit 5 unlike the display device 101 shown in FIG. Further, the inspection program may operate in the image signal source 200 instead of in the control unit 4.

  Conventionally, when a video device, a television device, or the like is used as the image signal source 200, it has been difficult to input and inspect the image signal from the image signal source 200 directly into the inspection apparatus 400. The inspection device 400 can easily perform inspection by displaying it as an image on the display device 102 and reading it by the sensor 301. In addition, by using a sensor capable of non-contact detection as described above in Embodiment 1, it is possible to easily inspect even in an environment where people are difficult to enter, such as a clean room.
