Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image information communication device such as a video conference system or a monitoring device capable of controlling a camera on a transmitting side from a receiving side.

[0002]

2. Description of the Related Art In a video conference system or the like, as disclosed in Japanese Patent Laid-Open No. 6-303607, a person in a conference room of his own station operates an operating device to make a person in a conference room of another station. Is displayed on the optimum position of the monitor, the camera in the conference room of another station can be controlled.

[0003]

As described above, in the image information communication apparatus such as the conventional video conference system, in order to display a specific area (such as a speaker) on the receiving screen,
Although it is necessary to control the camera on the transmitting side, in such a case, since the shooting position is registered in advance as a preset position, it takes a lot of time to operate the preset position setting.

Further, in order to display an area of a desired position other than the preset position, the operator on the receiving side (or the transmitting side) looks at the receiving monitor and operates the pan / tilt of the camera by a predetermined key operation or the like. It is necessary to perform an operation such as zooming, but in this case, the optimum position may not be displayed unless the above operation is repeated several times due to the time lag for communication time and the response speed of the camera.

That is, since the pan and tilt are excessively sent due to the time lag corresponding to the communication time, it is necessary to repeat the positioning operation several times. Furthermore, when attempting to align the camera at high speed, it is necessary to increase the drive speed of the pan / tilt drive motor, but in this case, the camera is moved too far in relation to the key operation. It is easy to store, and if it is fed too much, it is necessary to repeat the positioning operation several times, making adjustment difficult. Further, if it is attempted to prevent this and to perform accurate alignment, it is necessary to slow down the drive speed, and it takes time to move the camera to the target position.

Further, there is a difficulty in zoom adjustment as described above due to the time lag corresponding to the communication time. Further, like the above-mentioned pan and tilt, when trying to execute zoom adjustment of the camera at high speed, it is necessary to increase the drive speed of the zoom motor, but in this case as well, zooming is performed in relation to the key operation. It is easy to do too much, at that time,
It is difficult to adjust because you have to repeat the zoom operation several times. Further, if it is attempted to prevent this and to perform accurate alignment, it is necessary to slow down the drive speed, and it takes time to zoom to the target position.

Further, since an object near the center of the photographic screen is normally focused, the image is blurred in the out-of-focus portion, but it is necessary to display the portion clearly. , It was necessary to change the shooting position of the camera and move that part to the vicinity of the central part, so it was not possible to carry out this quickly.

The present invention has been made in order to solve such a problem, and does not require the complicated operation of setting the preset position for the photographing position adjustment of the camera, and also for the image transmission. It is an object of the present invention to provide an image information communication device that can be executed accurately and quickly, regardless of the time lag that occurs at any time and the response speed of the camera alignment mechanism.

Further, it is an object of the present invention to provide an image information communication device capable of performing a zooming operation of a camera accurately and promptly regardless of a time lag generated for image transmission or a response speed of zooming of the camera. It is intended.

Further, there is provided an image information communication device capable of quickly focusing on an arbitrary position on a display screen by a simple operation without moving a photographing position of a camera to obtain a clear image. That is the purpose.

And is realized by an LSI or software dedicated to calculation. Reference numeral 15 denotes a communication control unit that connects the present system to a communication network and controls communication of images (including sound) and control data, and the movement amount data calculated by the screen frame movement amount calculation unit 14 is also relevant. It is sent to the transmission side by the communication control unit 15 via the communication network. 16
Is a system control unit that controls the entire receiving side including the above units.

On the other hand, in FIG. 2 showing the structure of the transmitting side,
Reference numeral 21 denotes a camera for photographing a conference participant and the like. The camera 21 is placed on a pan head (not shown) for moving the imaging direction, and is controlled by the camera control unit 22.
The camera control unit 22 controls the imaging direction of the camera 21 based on the control amount calculated by the camera control amount calculation unit 23.

Reference numeral 24 denotes the video signal from the camera 21

Along with transmitting the data to the user side, the movement amount data and the like from the receiver side are captured. Reference numeral 27 is a system control unit that controls the entire transmission side including the above-mentioned units.

Next, regarding the above-described embodiment of claim 1, the operation of the image receiving side will be described with reference to the operation explanatory diagrams shown in FIGS. 1 and 3 and 4.

The operator displays a desired region as a screen frame on the reception screen by operating a predetermined operation, for example, a display key of an input device (operation keypad or the like) not shown. The display of the screen frame is performed by the screen frame display control unit 12.

The display of the screen frame as described above is a known technique, and the mechanism of the display will be briefly described below. As shown in FIG. 4, the screen frame F has an address a0 (X1, Y
When 1) and b0 (X2, Y2) are determined, drawing is possible. Further, if the size is determined in advance, if the position of a0, that is, (X1, Y1) is determined, (X2,
Y2) is automatically determined.

First, in the horizontal and vertical address counters,
The horizontal and vertical addresses are counted from (X0, Y0), the vertical address is Y1, and the horizontal addresses are X1 to X2.
If it is, the image signal is switched to the cursor signal and the frame line is drawn. Then, the image signal is switched again at X2.

When the horizontal address is X1 and the vertical address is Y1 to Y2, and the horizontal address is X2 and the vertical address is Y1 to Y2, the image signal is switched to the cursor signal and the frame line is drawn.

Then, while the vertical address is Y2 and the horizontal address is between X1 and X2, the image signal is similarly switched to the cursor signal and the frame line is drawn. As described above, the screen frame F can be displayed at a desired position and in a desired size.

The screen frame F can be moved to an arbitrary position on the screen by the operator by the screen frame movement control unit 12. As described above, the screen frame movement control unit 12 includes a pointing device such as a mouse and its control device,
Markers used when selecting and moving the screen frame can also be displayed.

That is, by pressing a predetermined display key, a screen frame of a predetermined size is displayed on the screen. The operator moves this screen frame to the center of the screen and moves it to the desired area. It should be noted that the position does not necessarily have to be the central position, and it means that the position is easy to see.

The states of the display screens before and after the movement are shown in FIGS. 3A and 3B, respectively. Now, it is assumed that an image in which the area a is located at the center is displayed as shown in FIG. When the operator wants to display the screen he wants to view on the screen with the area b in the center, he or she first operates a predetermined operation, for example, a moving key of an input device (an operation keypad or the like) (not shown). As shown in FIG.
A screen frame F of a certain size centered on the area and a moving marker M are displayed. For convenience of explanation, the screen frame F in the area a is shown by a dotted line. In the case of this example, the marker M is displayed at the apex of the lower right corner.

The operator moves the screen frame F to the area b while watching the screen frame F which moves following the movement of the marker M. Therefore, by performing a predetermined operation, for example, operating a stop key of an input device (an operation keypad or the like, not shown), that position is determined and displayed as the position of the screen frame F after movement (displayed by a solid line frame). ). In the actual operation, the display of the screen frame F is as described above, and the principle is the same for the marker M, which is realized by replacing the image data of the address with the signal of the marker. Control of these displays is generally performed by using the above-mentioned LSI called a graphic display controller. The above-mentioned display key, move key, stop key and the like can be realized by a single switch such as a lever switch.

When the position of the screen frame F after the movement is determined as described above, the screen frame movement amount calculation unit 14 calculates the movement amount of the frame from the area a to the area b on the display screen. . This amount of movement can be represented by the number of pixels in the vertical and horizontal directions, for example. Then, the movement amount of the screen frame F is transmitted by the communication control unit 15 to the image transmission side system shown in FIG.

Next, the operation of the image transmitting side will be described (see FIGS. 2 and 3). The camera control amount calculator 23 of FIG.
Is the amount of movement of the camera direction (imaging direction) required to set the area within the moved screen frame to the center position of the imaging area based on the transmitted movement amount of the screen frame and the current camera position information. Is calculated as the angle of rotation in the horizontal and vertical directions.
Then, the camera 21 on the transmission side is moved by the camera control unit 22 by the calculated movement amount. As a result, on the receiving side, an image centered on the area b is displayed on the screen as shown in FIG.

As described above, by moving the screen frame to any desired position on the screen, it is possible to move the screen frame within the screen frame without causing problems such as delay of communication time and overshoot due to responsiveness. Since the area can be brought near the center of the screen, the desired portion can be displayed accurately and quickly by a simple operation.

In the above description, the screen frame is first displayed in the center of the screen. However, without displaying the first screen frame, a pointing device such as a mouse is used.
The area to be displayed in the center of the screen may be drawn from the beginning with a frame and set.

FIG. 5 is a block diagram showing a main configuration of the receiving side of the video conference system according to the embodiment of the invention described in claim 2, and the same reference numerals as those in FIG. 1 indicate the same or corresponding portions. . Although the configuration on the transmission side is the same as that in FIG. 2, a camera equipped with a zoom lens is used as the camera 21, and the camera control amount calculation unit 23 uses the calculation data from the reception side to control the direction of the camera 21. And the zoom control amount, and based on these, the camera control unit 2
Reference numeral 2 controls the orientation and zoom amount of the camera 21.

In FIG. 5 showing the configuration of the receiving side, 17 is a screen frame size changing unit for changing the size of the screen frame displayed by the screen frame display control unit 12 to an arbitrary size desired by the operator. The screen frame size can be easily changed by dragging the frame line with a pointing device such as a mouse. Reference numeral 18 denotes a screen frame size calculation unit that calculates the ratio of the screen frame size to the total display screen size. Like the screen frame movement amount calculation unit 18, it is realized by a dedicated LSI or software for calculation, and the calculation result is obtained. Is similarly sent by the communication control unit 15 to the transmitting side via the communication network. Here, the screen frame size changing unit 17, the screen frame display control unit 12, and the screen frame movement control unit 13 implement the setting means according to claim 2.

Next, regarding the second embodiment, first, the operation on the image receiving side will be described with reference to the operation explanatory diagrams shown in FIG. 5 and FIG.

In the same manner as in the above-described embodiment, the operator uses the pointing device such as a mouse to enlarge or reduce the screen frame displayed by the screen frame display control unit 12 and moved by the screen frame movement control unit 13. By doing so, the screen frame size changing unit 17 can change the size of the screen frame to a size desired by the operator. However, the display of the screen frame at this time is preferably a rectangle whose horizontal and vertical ratio is equal to the aspect ratio of the monitor 11. Thus, the operator can set the area that the user wants to display on the full screen as the area within the screen frame and display it on the screen.

When the size of the screen frame is changed, the ratio of the size of the screen frame to the total display screen size (ratio of horizontal and vertical sizes) is calculated by the screen frame size calculation section 18, and the communication control section is calculated. 15 is sent to the sender.

Further, the movement amount of the displayed screen frame with respect to the central portion of the screen is calculated by the screen frame movement amount calculation unit 14 in the same manner as in the above-described embodiment and is sent to the transmission side.

Next, the operation of the image transmitting side will be described (see FIGS. 2 and 6).

First, in accordance with the amount of movement of the screen frame sent from the receiving side, in the same way as the operation of the above embodiment, the camera 21 is controlled so that the area within the screen frame is displayed in the central portion of the received screen. The orientation is controlled, and the set area is displayed at the center of the receiving screen on the receiving side.

Next, by the zoom control amount calculation function of the camera control amount calculation unit 23, the size of the screen frame size with respect to the current zoom position information of the camera 21 and the size of the entire display screen size transmitted from the receiving side. And the zoom movement amount required to display the specified screen frame on the entire display screen on the receiving side. Then, the camera control unit 22 zooms in the camera 21 by that amount.
In this way, the area designated on the receiving side moves to the center of the screen on the receiving side, and is enlarged and displayed on the full screen (see FIG. 6).

In the above description, the screen frame is first displayed in the center of the screen, but without displaying the first screen frame, a pointing device such as a mouse is used.
A configuration may be adopted in which a region to be zoomed in is drawn from the beginning by a frame and set.

To return to the state before zooming in, the state may be stored so that the user can zoom out and return to the initial state by one operation by operating a preset key or the like.

Although the above operation has been described for the case of zooming in, the operation of zooming out can be similarly quickly executed by performing the reverse processing for the relationship between the size of the entire display screen and the designated area. .
