DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera system capable of controlling and driving a movable optical member such as a zoom and a focus, and a lens system used in the camera system.

[0002]

2. Description of the Related Art As shown in FIG. 8, in a television camera system as a conventional camera system, a television camera body 101 as an image pickup device is connected to a photographic lens barrel 102, and a zoom as a photographic lens remote control device. The demand 103 and the focus demand 104 are connected and configured. By operating the zoom demand and the focus demand, an operator such as a cameraman can zoom and focus a television lens as a taking lens barrel, and can create a screen according to a situation.

FIG. 9 shows a lens system in a conventional television camera system, and shows a block diagram in controlling a movable optical member such as zoom and focus. 8, when an operator such as a cameraman operates a command member of the zoom demand and the focus demand in the remote control device 105, a command voltage 106a corresponding to the operation amount is generated from the command operation amount detection unit 106, and this is generated. A command control unit 107 composed of an analog circuit or the like converts the signal into a command voltage signal 107a suitable for a television lens device and inputs the command voltage signal 107a to a lens barrel 102 as a photographing lens device.

The command voltage signal 1 input to the lens barrel 102
07a is input as a command value to the zoom, focus, etc. drive control unit 110 constituted by an analog servo circuit and the like. Output signal 110 of drive control unit 110 for zoom, focus, etc.
By a, the motor for operating the zoom, focus and the like is driven, and the movable optical member 109 linked to the motor is operated.

Conventionally, in driving operations such as zooming and focusing of a television lens, the servo characteristics and operability can be easily changed due to differences in shooting targets such as drama shooting and sports broadcasting, and differences in operation methods for each cameraman. Was required to be

For example, in a drama shooting in a studio, a zooming requires a servo characteristic capable of smooth zooming by slow zooming rather than a speedy operation, and a focusing requires a distance of a shooting set in the studio. In the range, operability that facilitates focusing is required.

On the other hand, in outdoor photography, for example, in baseball broadcasting, in order to chase a fast-moving subject or ball, servo characteristics are required so that the zoom and focus are quickly at maximum speed, and the focus is easier to focus on the infinite side than on the closest side. Such operability is required.

As described above, in response to a demand to easily change the servo characteristics and operability of the television camera system according to the difference in the photographing object and the photographer's preference, the conventional television camera system or lens system uses the television lens. The servo characteristics of the device could not be changed.

In some focus demands and zoom demands, as shown in FIG. 9, the selection switch 108 is switched or the constant of an analog circuit in the demand is switched discontinuously or continuously by using a volume, so that the operation amount and In some cases, the operability of demand is changed by changing the relationship between command voltages.

[0010]

However, the method of changing the operability by changing the command value for the operation amount by switching the analog circuit constant in the demand using a switch or a volume has the following disadvantages. .

The servo characteristics of the television lens device itself cannot be changed, and the operability including the servo characteristics cannot be improved. In addition, the switch between the demand operation amount and the command amount can be switched by switches attached to the zoom demand and focus demand, and only a limited number of fixed patterns set in advance by hardware can be selected. It was not possible to satisfy all shooting conditions and operator demands with a fixed pattern.

Further, the method of continuously changing the circuit constant by the volume has been very complicated since the volume adjustment and the operation check must be performed several times, and this operation must be performed every time the photographing is performed. In addition, these demands can only be selected from a preset relationship between a command amount and a command voltage, and cannot be easily changed to a setting desired by an operator and stored.

Further, as shown in the conventional example, the only items that can be changed are the operation amount and the command amount of the operation member for zoom demand or focus demand.

Claims (15)

[Claims] A communication unit configured to communicate with an external device; a reading unit configured to read the setting information from an external device capable of setting setting information related to photographing via the communication unit; And a control means for performing an operation for a specific photographing. 2. A communication means for communicating with an external device, and via the communication means, the setting information is read from an external device capable of setting first setting information relating to photographing, and a second setting relating to photographing is performed. A camera system comprising: a reading unit that reads the setting information from an external storage medium that stores information; and a control unit that performs an operation for specific photographing using the read setting information. 3. The camera system according to claim 1, wherein the setting information is a plurality of types of control parameters of a movable optical unit. 4. A setting means for judging that the external device has been connected, wherein the reading means enables reading of the setting information when the connection with the external device is judged by the judging means. 4. The camera system according to claim 1, wherein the camera system is switched. 5. The camera system according to claim 1, further comprising display means for displaying information corresponding to the contents of said setting information read by said reading means. 6. The camera system according to claim 2, further comprising recording means for storing the first setting information read from the external device in the external storage medium. 7. The camera system according to claim 1, wherein a personal computer is used as the external device, and the setting information can be changed by operating the personal computer. 8. A communication unit for communicating with an external device, a reading unit for reading the setting information from an external device capable of setting setting information relating to photographing via the communication unit, and using the read setting information.
