Abstract

PURPOSE:To smoothly proceed with a video conference by storing a finely adjusting signal, at the time of rotating and moving a camera in the direction of a prescribed person and finely adjusting the camera, in a prescribed address. CONSTITUTION:For example, when a camera 1 is to be rotated and moved in the direction of a position 1 in order to direct the camera 1 to a position 1' where a person 1 exists, and further, when the camera 1 is to be finely adjusted, a position 1 instructing signal from an operating device 4 is made to branch and added to a setting circuit 50 in a control circuit 3 and a storing circuit 70. Voltage for setting the camera 1 to the position 1 is outputted from the setting circuit 50. Data for a PAN fine adjustment for the position 1 are inputted and stored into the storing circuit 70, and the data are added to an adder-subtracter 63. A value obtained by an addition in the adder-subtracter 63 is sent to a swivel base 2, and the camera 1 is directed in the direction of the position 1'. As the result, when the camera is directed in the direction of a person 2 (position 2) next and set in the direction of the person 1 again after that, the corresponding data are read from the storing circuit 70, and the camera is set in the direction of the position 1'.

Description

[Detailed Description of the Invention] [Summary] The present invention relates to a method for storing preset positions at any time in a TV conference in which a conference is held using a television (hereinafter referred to as a TV) and a microphone, which are connected between remote locations via a communication line. The purpose of this TV conference is to provide a method for storing preset positions that can be advanced at any time, and is a TV conference in which remote locations are held using a TV and microphone connected by a communication line, and includes control signals and fine adjustments for rotationally moving the camera. In a control circuit that inputs a signal to an adder/subtracter, performs a predetermined addition/M calculation, and rotates the camera in the direction of the speaker based on the output signal, a memory that stores a fine adjustment signal corresponding to the control signal at a predetermined address. Means is provided and configured to read out the fine adjustment signal corresponding to the control signal stored in the storage means when the control I-fold signal is input, and input it to the adder.

[Industrial application field]

The present invention relates to an improvement in a method for storing precent positions at any time in a TV conference in which remote locations are connected through a communication line using a TV and a microphone.

At this time, there is a need for a method for setting preset positions that allows the TV conference to proceed smoothly.

[Conventional technology]

FIG. 3 is a configuration block diagram of an example of a device used for a video conference.

FIG. 4 is a block diagram of a control circuit using a conventional pre-sent position setting method.

FIG. 3 shows a TV conference in which there are four attendees (persons ■ to ■) in one conference room, and for example, when person ■ is speaking, a moderator (not shown) operates the controller 4. This shows a case where the camera 1 attached to the swivel base 2 is set in the direction (position 2) of the person 2 via the control circuit 3.

Next, suppose, for example, person ■ speaks. Assume that the person ■ is seated at a position slightly deviated from the normal position, as shown by the dotted line in the figure. In this case, the camera 1 is
After setting the PA to position ■, as shown in Figure 4,
N (rotation in the left and right direction) is finely adjusted using the controller 4, and this output signal is added to the adder/subtractors 6 to 3 in the control circuit 3 and the output (position ■) of the setting circuit 5, and then directed to the swivel base 2. and send it. Then, the camera 1 was rotated in the direction shown by the dotted line in FIG. 3 (position ■).

[Problem that the invention seeks to solve]

However, in the preset position setting method described above, for example, if you finely adjust the camera position at position ■ to position ■°, then turn the camera to position ■ and then again to position It will be set to the previous fine-tuned position. For this reason, fine adjustments had to be made again, which posed the problem of making it difficult to proceed smoothly with the video conference.

Therefore, an object of the present invention is to provide a method for storing precent positions at any time, which allows the above-mentioned TV conference to proceed smoothly.

[Means for solving problems]

The above problem is solved by the circuit configuration shown in FIG.

That is, in FIG. 1, a teleconference is held between remote locations using a television and microphone connected by a communication line, and a control signal and a fine adjustment signal for rotating the camera are input to an adder/subtractor to set a predetermined value. In the control circuit that performs addition and subtraction and rotates the camera in the direction of the speaker based on the output signal, 700 is a storage means that stores an 8A adjustment signal corresponding to the control signal at a predetermined address.

Then, when the control signal is input, the fine adjustment signal corresponding to the '#All1 signal stored in the storage means 700 is read out and input to the adder 600.

[Effect]

In FIG. 1, when the camera is rotated and finely adjusted in the direction of a predetermined person, a fine adjustment signal corresponding to a control signal for rotationally moving the camera is stored in a storage means 700 at a predetermined address.

As a result, when the camera is rotated in the direction of a predetermined person for fine adjustment, then rotated in the direction of another person, and then rotated again in the direction of the original predetermined person, the storage means 700
The data stored in is outputted and input to an adder/subtractor 600 for addition and subtraction, and the camera is rotated in the original finely adjusted direction.

〔Example〕

FIG. 2 is a block diagram of a control circuit according to an embodiment of the present invention.

The same reference numerals indicate the same objects throughout the drawings.

In FIG. 2, for example, in order to direct the camera l toward the position ■ where the person ■ is located, in order to make further fine adjustments by rotationally moving it in the direction of the position ■, the operator 4 shown in FIG.
The position ① instruction signal from is branched and applied to the setting circuit 50 in the control circuit 3 and also to the storage circuit 70.

The setting circuit 50 outputs a voltage for setting position (3).

On the other hand, data for fine adjustment of the PAN at position (2) is input to the memory circuit 70. Then, among the addresses predetermined as position (2), the fine adjustment data is stored in the PAN fine adjustment address, and the same data is added to the adder/subtractor 63. The value added by the adder/subtractor 63 is sent to the swivel base 2, and the camera 1 is directed in the direction of position 2 as shown by the dotted line in FIG.

As a result, you can then move the camera in the direction of the person (position).
When set in the direction of the person ■ again after pointing at
The corresponding data is read from 0 and set in the direction of position ``■''.

〔Effect of the invention〕

As described above, according to the present invention, a TV conference can proceed smoothly.
