Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, video information that automatically adjusts the resolution and brightness of the video information that enables efficient use of computer resources according to the situation of the user in a communication system. It relates to an adjusting device.

[0002]

2. Description of the Related Art Use of a videophone system or a videoconference system can be considered as a communication means by which persons far from each other can exchange more information. In such a system, when a material to be presented to the other party, a facial expression of a person on the transmission side, and the like are photographed and transmitted, adjustment of the camera aperture and photographing environment for the photographing is performed on the transmission side.

In addition, many systems have been proposed, such as a multimedia conference system, which can display the facial expressions and materials of conference participants by using a plurality of moving image windows (windows for displaying moving images). It has also been realized.

In such a system, the facial expressions of the participants in the conference, the materials to be presented to the participants, etc. are displayed in a plurality of moving image windows, and the conferences can be held even by persons who are separated from each other.

[0005]

However, in a videophone or videoconference system, when the material to be presented to the other party or the person at the window is photographed, the sender determines the reception status of the recipient. You have to adjust the aperture of the camera while grasping.

Also, in a multimedia conference system, participants do not necessarily need all moving image windows.

Thus, in the conventional transmission of image information,
Since it is transmitted without reflecting the situation of the user, it is transmitted in the same way as the image information that the user is paying attention to, even for the video information that the user is not paying attention to, and the point of efficient use of computer resources Turned out to be a problem.

The present invention is an improved CCD which is a prior application.
The (solid-state image sensor) is used to adjust illuminance information and / or image resolution. The improved CCD is C
This is a system in which the amount of transmission of electric charges of a CD is improved.

Therefore, the improved CCD will be described.

FIG. 1 shows a CCD of the current system and a C of the improved system.
It is the figure which showed the structure with CD typically. Current method C
With a CD, as shown in FIG.
A single transfer gate is used. Therefore, only one packet signal can be sent per two pixels.

On the other hand, in the improved CCD, as shown in FIG. 1 (2) or (3), a structure of 8 gates per 2 pixels is adopted to increase the number of transfer packets. As a result, a maximum of 3 packets of signals can be sent per pixel.

As shown in FIG. 1 (2), the CC of the improved system
In D, the number of transfer packets is increased, and signals of two different accumulation periods (for example, different shutter speeds such as 1/60 second and 1/1000 second) are independently read out to combine these. Therefore, it becomes possible to handle signals with a wide dynamic range.

The resolution of NTSC is obtained by mixing PD (photodiode) signals of even lines and PD signals of odd lines. It is known that if both signals are handled independently without being mixed, the resolution can be improved by about 30% (Ishigami et al .: 1/2 inch 380,000 pixel full image readout type CCD image sensor, TV Technical Report of John Society, Vol.17, No.16, pp.39-44 (199
3)).

Therefore, when the improved CCD is used, the resolution can be adjusted according to the situation. As a result, if these two types of resolutions are switched according to the situation, it is possible to obtain a high-resolution image without unnecessarily using computer resources (network, storage capacity, etc.).

FIG. 2 shows a CCD of the current system and a C of the improved system.
It is a figure showing the situation of the picture to the subject with different illuminance by CD. Since the current CCD has a narrow dynamic range, depending on the subject, the outside background may be white out or the room may be black out.

Therefore, in the CCD of the current system, the amount of light incident on the CCD is adjusted by using a mechanical diaphragm or the signal storage time is adjusted by using an electronic shutter while observing the image quality of an image to be picked up. Therefore, it is necessary to adjust the illuminance range to be imaged.

On the other hand, in the improved CCD, the phenomenon such as white out or black out does not occur because the dynamic range is wide.

FIG. 3 is a diagram showing the performance of the improved CCD. In the improved CCD, as described above, 1/60
When signals with different accumulation times of seconds and 1/1000 seconds are independently read, the CCD dynamic range becomes 13 times or more. Also, the shutter speed is 1/100000
If it is changed to seconds, the saturation level of the photodiode becomes 1300 times or more that of the conventional one.

FIG. 4 is an image taken by using the improved CCD. Regarding the accumulation time, as in the case described above, the accumulation time of the high illuminance image is 1/1000 second, and the accumulation time of the standard illuminance image is 1/60 second. Current CC
When D is used, it is not possible to clearly project both the light bulb and the can with different illuminance, but when the improved CCD is used, both the light bulb character and the can character can be seen, as shown in FIG. Can be projected.

Therefore, the present invention is mainly based on the improved CCD.
It is an object of the present invention to provide a video information adjustment device that enables efficient use of computer resources by adjusting the resolution and / or the brightness of video information using the.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. (First Embodiment) FIG. 5 is a block diagram of the first embodiment according to the image information adjusting apparatus of the present invention. The video information adjustment device is in a form capable of adjusting illuminance information between terminal devices. That is, the input unit 502 of the terminal 501 is a camera, and the illuminance information acquisition unit 511 and the illuminance information adjustment unit 51.
2 is provided. The illuminance information acquisition unit 511 has an improved CCD and collects image information. The illuminance information adjustment unit 512 performs brightness adjustment on two different high illuminance information and standard illuminance information acquired by the improved CCD, and a part of the brightness-adjusted extended image information obtained as a result. Is a circuit for sending the image information and the information of the imaging condition corresponding to the above to the identifier adding section 513. Output part 5
A display device (display or the like), an audio output device (speaker or amplifier or the like), a recording device (VTR, hard disk, optical disc or the like), a printer, or the like can be connected to 03. The transmission unit 504 is a transmission device compatible with LAN, CATV, modem, digital PBX, or the like. The terminal control unit 505 is a control device that is in charge of overall control of these units.

The input unit 502 further includes a keyboard, a mouse, a digitizer, a touch panel, a light pen,
An input device such as a microphone can also be connected. Also,
For the overview of the terminal 501, refer to FIG.

Next, the operation of this embodiment will be described.

For the sake of explanation, it is assumed that in transmitting and receiving a certain image, the terminal on the transmitting side is the upper terminal 501 in FIG. 5 and the terminal on the receiving side is the lower terminal 501. (1) Operation of the terminal 501 on the transmission side FIG. 6 shows a state in which the two types of image information acquired by the illuminance information acquisition unit 511 are adjusted to one type of image information and the adjusted image information is output. It is a figure. The illuminance information acquisition unit 511 acquires two types of image information, high illuminance information and standard illuminance information, and outputs them individually and independently to the illuminance information adjustment unit 512. Also, the illuminance information acquisition unit 511
Outputs to the illuminance information adjusting unit 512 information on the shooting condition, which is information such as the charge accumulation time obtained as the shooting condition.

The illuminance information adjusting unit 512 performs brightness adjustment on the high illuminance information and the standard illuminance information input from the illuminance information acquisition unit 511, and a part of the brightness-adjusted expanded image information obtained as a result. The image information and the information on the imaging condition corresponding to are sent to the identifier adding unit 513.

Here, the brightness adjustment of the illuminance information will be described with reference to FIG. 9 showing an example of the processing. First, addition processing for adding high illuminance information to standard illuminance information is performed. Then, the slope of the expanded illuminance information obtained by the addition processing is linearly interpolated by calculation (γ correction). As a result, the brightness-adjusted extended image information is obtained.

The illuminance information adjusting section 512 sends a part of the brightness-adjusted extended image information (brightness-adjusted image information) corresponding to a preset predetermined range to the identifier adding section 513. The reason for sending a part is that the improved CCD's dynamic range is wider than the current monitor's dynamic range. Therefore, in the current monitor, all of the high range image information output from the improved CCD is output. Because it cannot be displayed. It is also because the amount of transmission is not increased. Note that the predetermined range set in advance is, for example, R
Suppose it is stored in AM.

The identifier adding section 513 adds the information of the image pickup condition to the image information whose brightness has been adjusted and sends it. Transmission unit 5
In accordance with the control of the terminal control unit 505, reference numeral 04 denotes the reception side terminal 501 of the brightness-adjusted image information and the imaging condition information sent from the identifier adding unit 513 via the transmission path.
Send to. (2) Operation of the reception-side terminal 501 The brightness-adjusted image information and imaging condition information transmitted from the transmission-side terminal 501 are received by the transmission unit 504 of the reception-side terminal 501. The terminal control unit 505 is a transmission unit 50.
The output unit 503 outputs the brightness-adjusted image information received in step 4.
Send to the monitor connected to. The monitor displays an image according to the brightness-adjusted image information.

Here, when the operator on the receiving side wants to change the luminance range of the image displayed on the monitor,
Based on the state of the image displayed on that monitor,
By changing the inclination of the extended illuminance information described above, it is possible to set the image displayed on the monitor so that it is easy to see.

The brightness range of the image displayed on the monitor can be changed by the operator pressing one of the up and down (or left and right) arrow keys corresponding to the direction of the desired brightness range. It is done by being selected. The code corresponding to the arrow key selected by the operator is input to the input unit 502.

Under the control of the terminal control unit 505, the transmission unit 504 transmits the code input to the input unit 502 to the transmission-side terminal 501 via the transmission path.

Instead of the code corresponding to the arrow key, information about the desired brightness range may be sent. (3) Operation of the terminal 501 on the transmitting side The transmitting section 504 on the transmitting side receives the code corresponding to the arrow key transmitted from the terminal 501 on the receiving side. The terminal control unit 505 changes the preset predetermined range stored in the RAM based on the code corresponding to the arrow key.

The illuminance information adjusting section 512 is a part of the brightness-adjusted extended image information (brightness-adjusted image information) corresponding to the changed predetermined range stored in the RAM, and the information of the imaging condition. Is sent to the identifier adding unit 513.

The identifier adding section 513 adds the information of the image pickup condition to the image information whose brightness has been adjusted and sends it. Transmission unit 5
In accordance with the control of the terminal control unit 505, reference numeral 04 denotes the reception side terminal 501 of the brightness-adjusted image information and the imaging condition information sent from the identifier adding unit 513 via the transmission path.
Send to. (4) Operation of the reception-sided terminal 501 The brightness-adjusted image information and imaging condition information transmitted from the transmission-sided terminal 501 are received by the transmission unit 504 of the reception-sided terminal 501. The terminal control unit 505 is a transmission unit 50.
The output unit 503 outputs the brightness-adjusted image information received in step 4.
Send to the monitor connected to. The monitor displays an image according to the brightness-adjusted image information. As a result, it is possible to set the brightness of the image information sent from the terminal 501 on the sending side to a range of brightness desired by the operator on the receiving side.

By the way, even if the brightness of the image information is changed in this way, the imaging condition of the illuminance information acquisition unit 511 in the terminal 501 on the transmitting side may not be appropriate. In such a case, it is necessary to change the imaging condition.

In the present embodiment, the information of the image pickup condition is transmitted to the terminal 501 on the receiving side together with the image information whose brightness has been adjusted. Therefore, at the receiving terminal 501,
Based on the information of the imaging condition, the imaging condition of the illuminance information acquisition unit 511 in the terminal 501 on the transmission side can be changed within the operable range of the illuminance information acquisition unit 511.

The operator of the receiving terminal 501 is, for example,
The imaging condition of the illuminance information acquisition unit 511 in the terminal 501 on the transmitting side is changed using the keyboard. Information on the changed imaging conditions is input to the input unit 502. Under the control of the terminal control unit 505, the transmission unit 504 transmits the information of the changed imaging condition via the transmission path to the transmission-side terminal 5
Send to 01. (5) Operation of the terminal 501 on the transmitting side The transmitting unit 504 on the transmitting side receives the changed imaging condition from the terminal 501 on the receiving side. The terminal control unit 505 changes the imaging condition of the illuminance information acquisition unit 511 based on the changed imaging condition received by the transmission unit 504. When changing the imaging conditions, the accumulation time of the CCD may be controlled according to a predetermined rule (for example, in order to increase the illuminance to 16 times the conventional one, the shutter speed of the camera for obtaining a high illuminance image is 1/1000. Seconds, and change the shutter speed of the camera according to the work situation of the user).

Illuminance information acquisition unit 51 whose imaging conditions are changed
1 acquires two types of image information, high illuminance information and standard illuminance information, based on the imaging conditions, and outputs them individually and independently to the illuminance information adjusting unit 512. The illuminance information acquisition unit 511 also outputs the changed imaging conditions to the illuminance information adjustment unit 512.

As is clear from the above, according to the present embodiment, the luminance-adjusted image information sent from the terminal 501 on the transmitting side is the information on the luminance range selected by the operator on the receiving side. Becomes In addition, the illuminance information can be managed independently, which increases the cost, but improves the degree of freedom of the user's operation. Furthermore, the brightness adjustment is performed on the side of the imaged terminal,
Since the type of image information is sent to the transmission path, the transmission capacity can be small.

In this embodiment, the imaging condition information is sent to the receiving terminal 501, but the imaging condition information may not be sent to the receiving terminal 501. In this case, the improved CC in the illuminance information acquisition unit 511
The dynamic range of D is treated as fixed, and the terminal 501 on the receiving side adjusts the dynamic range within the fixed range.

Also, the form of the terminal network is not limited to the bus type network, but may be FDDI or ATM-LAN.
The network may be a ring type network, or may be a star type network.

Further, as another method of obtaining the high illuminance information and the standard illuminance information in the brightness information acquisition unit 511, two different illuminance information for the same shot are used by using a camera or CCD having two different shutter speeds. The threshold value may be set for the two pieces of illuminance information. (Second Embodiment) FIG. 7 is a block diagram of a second embodiment according to the image information adjusting apparatus of the present invention, in which the illuminance information is managed centrally at one place. First, the configuration of the terminal 701 will be described. The input unit 702 of the terminal 701 is a camera and includes an illuminance information acquisition unit 711. The illuminance information acquisition unit 711 has an improved CCD and collects image information. A display device (display or the like), an audio output device (amplifier and speaker or the like), a recording device (VTR, hard disk, optical disk or the like), a printer and the like can be connected to the output unit 703. The transmission unit 704 is a transmission device compatible with LAN, CATV, modem, digital PBX, or the like. The terminal control unit 705 is a control device that is in charge of overall control of these units.

The input unit 702 further includes a keyboard, a mouse, a digitizer, a touch panel, a light pen,
An input device such as a microphone can also be connected.

Next, the configuration of the terminal support device 706 for controlling and managing the plurality of terminals 701 will be described. Transmission unit 7
04 is LAN, CATV, modem or digital PBX
Etc. is a transmission device for transmitting information corresponding to the above. The illuminance information adjusting unit 712 is a circuit that sends out two different types of high illuminance information, standard illuminance information, and information of imaging conditions acquired by the improved CCD. Terminal support control unit 707
Controls all of these parts and controls a plurality of terminals 701,
It is a control device that manages.

Next, the operation of this embodiment will be described.

FIG. 8 is a diagram showing how the two types of image information acquired by the illuminance information acquisition unit 711 are independently transmitted. The illuminance information acquisition unit 711 sets high illuminance information (for example, an image when the charge accumulation time in the improved CCD is 1/1000 second) and standard illuminance information (for example, the charge accumulation time is 1/60 second). Two types of image information (i.e., the image in the case of the above), and each of them is independently output to the identifier adding unit 713. Further, the illuminance information acquisition unit 711 outputs information on the shooting condition, which is information such as the charge accumulation time obtained as the shooting condition, to the identifier adding unit 713.

The identifier adding section 713 adds the information of the photographing condition to each of the high illuminance information and the standard illuminance information, and sends each of the added information separately and independently. Transmission unit 7
Under control of the terminal control unit 705, 04 transmits each of the high illuminance information and the standard illuminance information sent from the identifier adding unit 713 to the terminal support device 706 via the transmission path.

The high illuminance information, the standard illuminance information, and the information on the shooting conditions transmitted from the terminal device 701 are received by the transmission unit 704 of the terminal support device 706. The terminal support control unit 707 sends the high illuminance information and the standard illuminance information received by the transmission unit 704 to the illuminance information adjustment unit 712. The illuminance information adjustment unit 712 generates brightness-adjusted image information in the same manner as the illuminance information adjustment unit 512 in the first embodiment.

Here, for example, the terminal support device 706 is
If it is a device used in the security management center, each of the terminal devices 701 corresponds to a surveillance camera installed in a place to be monitored. In this case, the terminal device 701
The illuminance information adjusting unit 712 is assigned to all or a part of the above. Then, the brightness-adjusted image information generated by the illuminance information adjusting unit 712 assigned to each terminal device is displayed on a plurality of monitors.

At this time, the two different types of high illuminance information and standard illuminance information are separately recorded in a recording device (not shown). Therefore, if the recorded image is analyzed later, more information than the image information of a normal camera is stored, and the analysis ability in the security system can be improved. In addition, it is possible to improve the analysis capability of the security system even if the image is recorded at a high resolution described later.

By the way, the reason why the information of the photographing condition is output from the terminal device 701 to the terminal support device 706 is for the same purpose as in the first embodiment. That is, this is to enable the terminal support device 706 to change the imaging condition of the illuminance information acquisition unit 711.

As is clear from the above, according to the present embodiment, the transmission capacity has twice as much information as that taken by a normal camera, but the dynamic range is wider than that of the conventional method. Information can be handled. Therefore, the receiving-side operator can obtain an image in a desired state by adjusting the image information having a wide dynamic range.

In the present embodiment, the terminal device 701
Although the illuminance information acquisition unit 711 is provided and the illuminance information adjustment unit is not provided, the illuminance information adjustment unit 711 of the terminal support device 706 may be provided.

Further, the identifier adding section 713 adds the absolute value of the charge accumulation time to each illuminance information and transmits it, but not limited to this, it may transmit the ratio of the charge accumulation time.

Further, the terminal support device 706 receives the high illuminance information and the standard illuminance information from a certain terminal device 701, generates the brightness-adjusted image information using them, and uses the generated information in another terminal device. It may be transferred to 701. Thereby, for example, the image quality of each monitor in a conference using a communication line can be collectively managed.

Further, a method in which the method of the first embodiment and the method of the second embodiment are mixed is also possible. For example, when the calculation processing capacity of the receiving terminal is high, the calculation of the illuminance information can be processed by its own terminal, so that the standard illuminance information and the high illuminance information are separately transmitted as in the second embodiment. You may. On the contrary, when the calculation capability of the receiver is low, the illuminance information is calculated in advance in the terminal of the transmission source (or in the terminal that can once calculate the illuminance information) as in the first embodiment. After that, the brightness-adjusted image information may be transmitted to the destination. (Third Embodiment) FIG. 10 is a block diagram of the third embodiment according to the image information adjusting apparatus of the present invention. The video information adjustment device is in a form capable of adjusting the resolution between terminal devices. That is, the input unit 1002 of the terminal 1001 is a camera, and includes a resolution information acquisition unit 1011 and a resolution information adjustment unit 1012. Resolution information acquisition unit 101
Reference numeral 1 has an improved CCD and sends out even-line PD signals and odd-line PD signals separately and independently for each field. Resolution information adjustment unit 1
012 uses the even-line PD signal and the odd-line PD signal sent from the resolution information acquisition unit 1011.
This is a device that generates image information with a predetermined resolution. The output unit 1003 includes a display device (display or the like), an audio output device (amplifier and speaker or the like), a recording device (VT).
R, hard disk, optical disk, etc.) and printer can be connected. The transmission unit 1004 uses LAN, CAT
It is a transmission device compatible with V, modem or digital PBX. The terminal control unit 1005 is a control device that is in charge of overall control of these units. The input unit 1002 is
Further, input devices such as a keyboard, a mouse, a digitizer, a touch panel, a light pen, a microphone can be connected.

Next, the operation of this embodiment will be described.

For the sake of explanation, in transmitting and receiving certain image information, it is assumed that the terminal on the transmitting side is the upper terminal 1001 in FIG. 10 and the terminal on the receiving side is the lower terminal 1001. (1) Operation of the terminal 1001 on the transmission side The resolution information acquisition unit 1011 separately and independently transmits the PD signal of the even line and the PD signal of the odd line for each field.

Here, the generation of image information of a predetermined resolution by the resolution information adjusting unit 1012 will be described.

1. Generation of Standard Resolution Image Information The resolution information adjusting unit 1012 uses the even-line PD signal and the odd-line PD in the same manner as the NTSC system, for example.
The signals are mixed to produce NTSC resolution image information. This is similar to the operation of a general CCD, and an image having the same resolution as that of a conventional CCD can be obtained. The resolution at this time is the standard resolution. This read control is the initial setting of this device.

2. When acquiring high resolution image information The resolution information adjusting unit 1012 processes the PD information of the even lines and the PD signals of the odd lines independently without mixing them, and thus the image information with the resolution increased by about 30% is obtained. To generate. The resolution at this time is high resolution.

FIG. 23 is a diagram showing a method for determining the window of interest of the user by utilizing the window size change information. Here, a method of determining the user's attention information (window) among the resources of the window will be described by taking a window size change as an example. A window display size changing unit is provided in a window for individually or jointly processing information, and the user explicitly changes the display size when the window is used by the window display size changing unit. The window size change detection unit 1726 detects whether or not the display size of the window has been changed, and when the display size has been changed, outputs the fact to the window information management control unit 1731. Then, the window information management control unit 1731 determines and manages the window whose display size has been changed as the window the user is currently focusing on.

When a plurality of windows can be determined as the window of interest, the window whose size has been changed most recently may be determined as the window the user is currently focusing on (more detailed window size). About the size of a certain size may be used as the window of interest).

If the time interval of interest of the window (when the window operation is frequently performed) is short (the time interval of interest is a fixed time or less), the window is considered as an erroneous operation by the user. You may consider it not.

With respect to other window resources managed by the window information management unit 1416, the window of interest can be determined in a similar manner. For example, by detecting a change in window focus or a display change between windows, it is possible to know which window is currently the target of information processing by the user.

FIG. 24 is a diagram showing a method of determining the window of interest of the user by using the owner information of the window. On the screen of the monitor, a joint information edit area 2434 is provided as a work area for jointly processing information, and a personal information edit area 2435 is provided as a work area for individually processing information. The window display position change detection unit 1727 detects movement of a window that the user wants to show to other users (a moving image window that is a topic target) to the joint information editing area 2434. Then, the window information management control unit 1731 performs communication control for displaying the window moved into the joint information editing area 2434 to other users.

The window display position change detecting section 1727 is set by the area in which information processing is jointly performed and the area in which individual information processing is performed in advance, and the user performs work in either area according to the purpose. It is possible to easily detect from which viewpoint the current work is performed.

FIG. 25 is a diagram showing a method of determining the user's attention information based on the information of the window display area change detection unit 1729. First, a window for displaying the material information is provided with a window display area changing unit 2536 for allowing the user to appropriately refer to a necessary portion of the material information for the content of the material information that cannot be displayed in the window. However, the user interface is not limited to the scroll bar as shown in the figure, and may be a push button type or the like. The window display area change detection unit 1729 detects whether the user has operated the window display area change unit 2536 to change the content of the displayed material. When the window display area change detection unit 1729 detects an operation on the window display area change unit 2536, the window information management control unit 1731 detects that the voice information for a certain time or more (for example, one second) is detected after the detection. , The window in which the operation was detected,
Considered as the window the user is paying attention to.

This is effective when a person is going to explain things and makes an instruction to clarify the target position and tries to convey his / her intention to the other party by voice (word).

The window information management control unit 1731
Although the window under consideration is determined, the instruction information management unit 1417 may make the determination.

Also, the window information management control unit 1731
In the above, the window of interest is determined based on the detection of the operation on the window display area changing unit 2536 and the detection of the audio information for a certain time or longer. However, the determination may be made based on either one of them. Good. (4) Instruction Information Management Unit 1417 FIG. 18 is a configuration diagram of the instruction information management unit 1417.

FIG. 22 shows the window information management unit 1416.
9 is a chart showing an example of management information of an instruction information management unit 1417. The window information management unit 1416 and the instruction information management unit 1417 manage the window operation, the contents of the changed instruction operation, the event occurrence person, the occurrence time, and the occurrence location information. The window operation unit may be a logical page, chapter, or section as a basic unit. Further, a personal information description means may be provided in the window to check changes in the description content (personal memo) of the personal information.

As is clear from the above, the work status management unit 1208 (or 1308) provided with the voice information management unit 1415, the window information management unit 1416, and the instruction information management unit 1417 for managing the change in the state of the voice depends on If
Since the user can detect where the instruction status to the video window and the audio status change, the period in which the user focuses on the video window can be more accurately determined.
This is because when a person tries to explain a certain matter (material), the voice is generated and the instruction to the material is generated at the same time. This enables finer control. In this case, since the control becomes complicated, the work status management unit 1208 (or 1308) does not necessarily have to include the voice information management unit 1415.

A work status management unit 120 including the above-mentioned units

208 (or 1308) detects the status of the camera operation by the user and the audio information by the video information management unit 1414 and the audio information management unit 1415, respectively. The camera operation by the user includes, for example, switching of video channels when there are a plurality of video sources, zoom operation of the camera, or operation of a storage device such as a VTR device. The work status management unit 1208 (or 1308) detects a target focused on by the user based on which position in the video information is designated and when.

As a result, depending on the user's instruction status,
It becomes possible to automatically set the resolution or brightness of the image to be high. In addition, when a person gives instructions to a document and explains it, the surroundings specified by the presenter should be sharpened, and the resolution should be reduced at other points (for example, points not near the center of the video window). By doing so, you avoid inadvertently using a lot of computer resources.

FIG. 26 is an image in which one user projects a “circuit board” material image on a monitor using a document camera and another participant points a finger to the “circuit board” image. It is the figure which showed a mode that it is overlaying (overlapping).
