Description

This invention relates to a control method for an imaging device. Currently, in the video production market, there is an increasing trend towards systems that allow remote control of network-connected imaging devices. Such systems include applications that allow users to change the imaging range (hereinafter referred to as the imaging range) by controlling the PTZ (pan, tilt, and zoom) of the imaging device while simultaneously displaying the captured image. Users of these applications can change the imaging range using devices such as joysticks. Furthermore, one method for controlling the imaging range of an imaging device is to control the PTZ (Phone-Targeted Zone) based on the position and size of the subject. Patent Document 1 discloses a method for controlling the zoom magnification so that the calculated ratio remains constant when zooming, by calculating the ratio between the entire area of the subject and a partial area of the subject (such as the head), in order to photograph the subject within a desired shooting range.

The embodiments of the present invention will be described below with reference to the attached drawings. Note that the configurations shown in the following embodiments are merely examples and are not limited to those illustrated. (Embodiment 1) Figure 1 shows the system configuration in this embodiment. The system in this embodiment includes an imaging device 100, an information processing device 200, a display 400, and a network 300. The imaging device 100 and the information processing device 200 are interconnected via a network 300. The network 300 is implemented using multiple routers, switches, cables, etc., compliant with communication standards such as ETHERNET®. Furthermore, the network 300 may be implemented using the Internet, a wired LAN (Local Area Network), a wireless LAN (Wireless LAN), a WAN (Wide Area Network), or the like. The imaging device 100 is a device that captures images and functions as an imaging means capable of controlling the imaging range. The imaging device 100 transmits the image data of the captured image, information on the date and time the image was captured, identification information for identifying the imaging device 100, and information on the imaging range of the imaging device 110 to an external device such as the information processing device 200 via the network 300. The information processing device 200 is, for example, a client device such as a personal computer with a program installed to implement the processing functions described later. In this embodiment, there is one imaging device 100, but there may be multiple. That is, multiple imaging devices 100 may be connected to the information processing device 200 via the network 300. In this case, the information processing device 200, for example, uses the identification information associated with the transmitted image to determine which of the multiple imaging devices 100 captured the transmitted image. The display 400 is composed of an LCD (Liquid Crystal Display) or the like, and displays images captured by the imaging device 100. The display 400 is connected to the information processing device 200 via a display cable compliant with communication standards such as HDMI (High Definition Multimedia Interface). Note that the display 400 and the information processing device 200 may be housed in a single enclosure. Next, the imaging device 100 according to this embodiment will be described with reference to Figures 2 and 3. Figure 2 is an example of an external view of the imaging device 100 according to this embodiment. Figure 3 is an example of a functional block of the imaging device 100 and information processing device 200 according to this embodiment. Note that among the functional blocks of the imaging device 100 shown in Figure 3, the functions of the image processing unit 112, system control unit 113, pan-tilt-zoom control unit 114, storage unit 115, communication unit 116, etc., are implemented as follows. That is, they are implemented by the CPU (Central Processi
