The image quality optimization processing unit 200 obtains from the server 40 and optimizes the video setting value accordingly.

  The image quality optimization processing unit 200 has been recognized as a connected device recognition unit 201 that recognizes a device connected to the image display device 20, and an information acquisition unit 202 that stores information acquired from the server 40 regarding the recognized device. The apparatus includes an incidental information acquisition unit 203 that stores incidental information such as weather information acquired from the server 40 for the device, and an incidental information input unit 204 that displays a user interface for inputting incidental information on the image display device 20.

  FIG. 2 is a block diagram of the image display apparatus according to the present embodiment.

  The image display device 20 includes the image quality optimization processing unit 200 described with reference to FIG. 1, and is a TV device mounted with a liquid crystal display unit that drives a liquid crystal display unit 210 with a display control unit 211 as a display unit. An image signal input unit 212 that is an interface, a memory 213 for temporarily storing data, a tuner 214 that receives broadcast waves via an antenna 214A, a control unit 215 that controls the operation of each unit, and a video signal decoding process An image signal processing unit 217, an image signal output unit 218 that encodes and outputs the decoded video signal into a display signal, an audio signal processing unit 219 that decodes the audio signal, and outputs the decoded audio signal An audio signal output unit 220; a light receiving unit 221 that receives light transmitted based on an operation of a remote controller (not shown); And a network interface 222 for connecting the image display device 20 in the network are connected by an internal bus 223 is constituted.

  The image signal input unit 212 is connected to a video input terminal (not shown), and monitors the connection of a connected device such as a video camera at regular time intervals.

  FIG. 3 is an explanatory diagram showing information stored in the image quality optimization processing unit.

  Here, information about a device connected to the image display device 20 is shown, and the currently connected device is a video camera of model name XXYZZ-001-A recognized by the connected device recognition unit 201. This video camera Gamma data, dynamic range, and contrast ratio setting values are acquired from the server 40 as acquired device information, and for the incidental information, weather information (in this case, clear sky) is included as additional information acquired from the server 40 (acquired incidental information). The location (here, park) is included as incidental information (input incidental information) input by the incidental information input unit 204 based on the user's operation.

  Thus, when there is incidental information, for example, when there is weather information of the date and time when the video signal was recorded, optimization processing is performed in consideration of parameters such as white balance and exposure according to the weather.

  The acquired device information may not be provided depending on the device connected to the image display device 20, and in this case, only the provided information is valid.

  The acquired device information shown in the drawing is an example, and the content varies depending on the connected device, but items that can be adjusted in the image display device 20 are displayed as the acquired device information.

  For the input supplementary information, a character input screen is displayed on the display screen of the liquid crystal display unit 210 by operating the remote controller of the image display device 20 and selecting the supplementary information input from the menu screen. The desired information is input by selecting.

  Note that a template (family, friends, pets, etc.) may be registered in advance for information, and the corresponding information may be selected and input from the template when inputting incidental information.

  FIG. 4 is a flowchart showing the operation of the image display system according to the present embodiment. The operation of this embodiment will be described below.

  First, the image display device 20 checks whether there is a connected device at regular time intervals (S1). If there is no connected device (S1: No), the system loops until a connected device is found. When a device is connected (S1: Yes), an inquiry is made to the server 40 via the network 30 to determine whether there is acquired device information about the connected device (S2). The server 40 returns a response to the inquiry from the image display device 20 regardless of the presence or absence of information (S3). When the acquired device information is acquired from the server 40 (S3: Yes), the corresponding acquired device information is held in the information acquisition unit 202 of the image quality optimization processing unit 200 (S4). Next, the image display apparatus 20 displays an alert on the liquid crystal display unit 210 as to whether or not incidental information such as a date and a shooting location is input. In order to input the incidental information, the user operates the remote controller to input the item of incidental information desired to be input (S5), and inquires the server 40 about photographing information such as weather based on the incidental information (S6). . When the supplementary information can be obtained from the server 40 (S7: Yes), it is held in the supplementary information acquisition unit 203 of the image quality optimization processing unit 200 (S8). Thereafter, referring to the acquired device information and the incidental information of the image quality optimization processing unit 200, the control unit 215 performs video setting optimization by setting parameters of the image signal processing unit 217 and the image signal output unit 218. (S9). After the optimization process is completed, the video input from the imaging device 10 is displayed on the liquid crystal display unit 210 (S10).

  On the other hand, if the acquired device information cannot be obtained from the server 40 in S3, the process ends (S3: No).

  Further, in S7, the incidental information cannot be obtained from the server 40 (S7: No), and when the user manually inputs the incidental information (S11: Yes), the incidental information to be input is input by operating the remote controller. . On the other hand, when it is determined that the user does not manually input the supplementary information (S11: No), the process proceeds to S9 with the content not including the supplementary information.

(Effect of the embodiment of the present invention)
