OF THE INVENTION

1. Field of the Invention

The present invention relates to a camera control apparatus and a camera control method, and particularly to a camera control apparatus and a camera control method capable of storing preset information on a camera.

2. Description of the Related Art

There has been a camera known to be capable of registering a plurality of patterns of camera state information as preset information formed of a pan coordinate, a tilt coordinate, a zoom position, a white balance value, and other parameters of the camera. In a camera of this type, the preset information is typically stored in a memory or any other suitable storage in the camera. The stored preset information is read as necessary, and the setting contained in the preset information is reflected in the camera.

However, since the capacity of the memory built in the camera is limited, the number of positions that can be registered as preset information is inevitably limited by the capacity of the memory. That is, when the number of pieces of preset information that can be set in a camera in use is, for example, sixteen, a seventeenth piece of preset information cannot be registered. On the other hand, since cameras have been used in a variety of applications, more users have been requesting increase in the capacity of storing preset information. To increase the capacity of storing preset information, an apparatus that controls the action of a camera stores preset information on the camera under control in some cases.

For example, JP-A-2004-201241 discloses a camera control apparatus including a camera capable of performing pivotal actions and an operation unit that controls pan, tilt, and other actions of the camera. In the technology disclosed in JP-A-2004-201241, the operation unit stores the actions of the camera performed when the camera is operated manually through the operation unit.

SUMMARY

- Top of Page


OF THE INVENTION

According to the method described in JP-A-2004-201241, the area in which preset information is stored (capacity) can be increased. However, according to the technology described in JP-A-2004-201241, all the actions of the camera performed when the camera is manually operated, that is, a plurality of pieces of preset information, are stored in a memory in the operation unit. Therefore, to incorporate the preset information in the state of the camera, the operation unit in which the preset information has been registered needs to be used. That is, the camera and the operation unit need to be used in a one-to-one relationship.

Further, in the related art described in JP-A-2004-201241, when a camera having preset information already registered therein is used, the preset information registered in the camera is disadvantageously difficult to use effectively.

Thus, it is desirable to increase the capacity of storing preset information without compromising an advantageous effect provided by a function in the related art that is the capability of registering preset information on the camera side.

A camera control apparatus according to an embodiment of the invention includes an input section to which a plurality of cameras the action of each of which is controlled by the apparatus are connected, each of the cameras including a first preset information storage section capable of storing up to n pieces of preset information on the state of the camera setting. The camera control apparatus further includes a second preset information storage section capable of storing (n+1)-th preset information to m-th preset information (n<m) in each of the plurality of cameras. The camera control apparatus further includes an operation input unit to which an operation of selecting a specific one of the plurality of cameras is inputted and an operation of instructing registration of the preset information on the selected camera or an operation of instructing readout of the preset information on the selected camera is inputted. When the operation of instructing registration of the preset information is inputted through the operation input unit, the preset information is registered in the first or second preset information storage section. When the operation of instructing readout of the registered preset information is inputted through the operation input unit, the preset information is read from the first or second preset information storage section. The read preset information is then incorporated into the state of the selected camera.

According to the above configuration, each of the cameras stores up to n-th preset information, and the camera control apparatus stores (n+1)-th preset information to m-th preset information.

According to the above embodiment of the invention, the capacity of storing preset information can be increased to the point where m pieces of preset information are stored at the maximum, and an advantage provided by storing preset information in each of the cameras can also be provided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

An embodiment of the invention will be described below with reference to the accompanying drawings. The embodiment will be described in the following order:

1. First Embodiment

2. Variations

1. First Embodiment Exemplary System Configuration

FIG. 1 shows an exemplary configuration of a system according to the present embodiment. A camera control apparatus according to the present embodiment of the invention is a video signal processing apparatus 100 having a video switcher function and a camera controller function. The video signal processing apparatus 100 shown in FIG. 1 is formed of a main unit 110 and an operation input unit 120. While the main unit 110 and the operation input unit 120 are separate units in the present embodiment, they may be integrated with each other.

The video signal processing apparatus 100 is a portable apparatus and used to, for example, relay events that take place in a large lecture hall, a large conference room, a live concert hall, and any other similar place and produce video content that introduces how the events have proceeded.

The main unit 110 shown in FIG. 1 is connected to four cameras C1 to C4 and a personal computer (hereinafter referred to as a PC) P1 as sources from which video images are inputted.

The cameras C1 to C4 are connected to SDI (Serial Digital Interface) input terminals (not shown) or any other suitable terminals of the main unit 110, and video images captured by the cameras C1 to C4 are inputted to the main unit 110 via the respective input terminals. The image capturing operation in the cameras C1 to C4 is synchronized with a sync signal supplied from the main unit 110.
