The input / output terminal 12 is a terminal for inputting / outputting image data. For these terminals, for example, a BNC (Bayonet Neil Concelman) connector for connecting a coaxial cable can be used. The input / output terminal 12 may be, for example, a connector for connecting a coaxial cable for transmitting a video signal (SDI signal) conforming to a serial digital interface (SDI) standard. Standards such as SD-SDI, HD-SDI, 3G-SDI, and 12G-SDI (4K standard) are defined for the SDI signal. These standards are used, for example, depending on the application. For example, HD-SDI is used in image processing for full high-definition broadcasting. Further, in 4K broadcasting, 3G-SDI and 12G-SDI are used. For the input / output terminal 12, a connector that can be commonly used in all of these standards is used.

A circuit information program is a program that defines connection information that defines the interconnection of a plurality of logical blocks and the operation of a logical block group consisting of a plurality of interconnected logical blocks or the operation of a plurality of logical blocks that are interconnected with each other. And can be a program of the image processing function circuit 21. The connection information is information for determining the interconnection of which logical block connects to which logical block in a plurality of logical blocks. The circuit information program may be provided from a device such as a network server that provides a program for the image processing function circuit 21. The circuit information acquisition unit 18 acquires, for example, a program of the image processing function circuit 21 as a circuit information program from a network server connected via a network. Further, the circuit information acquisition unit 18 may read and acquire the program of the image processing function circuit 21 recorded on the recording medium as a circuit information program.

The control unit 25 has a function of managing processing related to switching and activation of circuit functions and switching such as key acquisition, and concealing them from the application layer 26.
The control unit 25 automatically performs switching processing depending on the application to be used, so that the application does not need to perform processing related to switching such as switching and enabling circuit functions and key acquisition.
For example, when the user starts the application A26a, if the circuit information memory 17 does not have the program of the image processing function circuit 21 corresponding to the application A26a, it is acquired from a device such as a network server that provides the program of the image processing function circuit 21. Then, it is written to the circuit information memory 17 through the circuit information acquisition unit 18, the function switching unit 16 reconfigures the image processing function circuit 21, and authenticates by enabling and acquiring the key to make it available from the application A26a. ..

The image processing function is, for example, a frame buffer function for temporarily storing image data displayed on a display device. Further, the image processing function may be an image capture function for capturing image data displayed on a display screen, or an image mixer function for superimposing a plurality of image data. The application is a program for realizing these image processing functions.

Further, the application may be executed by utilizing these image processing functions. The application is, for example, supporting the creation of a telop or controlling the transmission of a telop, which is executed by using an image processing function.

Here, the telop is text information, symbol information, graphic information, and audio information that are superimposed, inserted, or combined with an original image such as a moving image or a still image (hereinafter, may be referred to as "superimposition, etc."). Alternatively, it is image information or information on a combination of these (hereinafter, may be referred to as "character information or the like"). The original image is, for example, a television image used for television broadcasting, a moving image used for a moving image distribution service, a display image displayed on a large display device, or the like. The telop data is data used for a telop that is superimposed on the original image. Telop data is created based on material data. The telop data is superposed on a part or all of the original image and broadcast, distributed, displayed, or the like. The telop may be called, for example, a caption, a subtitle, a ticker, an alert, a superimpose, etc., depending on the area, content, format, etc. used, and is included in the telop of the present embodiment. Applications that support the creation of telops include, for example, an application for teloping posts on SNS (Social Networking Service), an application for teloping weather forecasts, an application for teloping election results, and the like.

The application layer 26 can have one or more applications. FIG. 1 shows a case where the application layer 26 includes two applications, application A26a and application B26b, but the number of applications is arbitrary.

The application may be pre-registered in the image processing device 1, or may be provided by an application server (not shown). The application server is, for example, a virtual server constructed on a cloud network, and provides an application via the cloud network. The control unit 25 may reconfigure the image processing function circuit 21 according to the application selected by the user from various applications provided by the application server. That is, the user can update the image processing function and use the image processing device 1 without replacing the device (hardware) related to the image processing. When the application is stored in the cloud server, the image processing device 1 can form a virtual device by cooperating with the cloud server.

The device sales system 3 has, for example, a Web page for selling the image processing device 1, and processes a purchase request from the Web browser of the user terminal 2. The purchased image processing device 1 is delivered to the user. In step S11, the user purchases an image processing device 1 having an HD frame buffer function for temporarily storing an HD signal having a resolution of 1920 pixels × 1080 pixels as an image processing function.

The function sales system 4 is a system for selling an image processing function. The image processing function is provided, for example, as software related to the variable unit 20 described with reference to FIG. The software related to the variable unit 20 is, for example, a program or an application of the image processing function circuit 21.

Next, another example of switching the image processing function will be described with reference to FIG. FIG. 4 is a diagram showing another example of the function switching procedure in the image processing apparatus according to the embodiment.

The application ID is information that identifies the application, and is information that specifies the image processing function to be executed in the image processing device 1. When it is determined that the notification of the application ID has not been acquired (step S24: NO), the image processing device 1 repeats the process of step S24 and waits for the acquisition of the application ID.

On the other hand, when it is determined that the notification of the application ID has been acquired (step S24: YES), the image processing device 1 switches the image processing function based on the acquired application ID (step S25).
