[Table of Contents] The present invention will be described in the following order. Field of Industrial Application Conventional Technology Problems to be Solved by the Invention Means for Solving the Problems (FIGS. 1 to 8) Actions (FIGS. 1 to 8) Examples (FIGS. 1 to 8) Effects of the Invention

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing device and an image information transmission device, and more particularly to a television conference system for photographing persons and materials with a television camera (hereinafter referred to as a television camera) and transmitting them to each other. It is suitable for application.

[0003]

2. Description of the Related Art Conventionally, in this type of television conference system, for example, an image of a person photographed by a television camera is transmitted to a conference participant through a line, and the conference participant displays the face of the person displayed on the display. I am holding a meeting while watching.

[0004]

By the way, in this type of television conference system, a document such as a material is photographed by a television camera, and an image of the photographed material is
A still image may be transmitted to a conference participant, and each conference participant may hold a conference by viewing the material displayed on the display. However, when a document such as a document is shot with a TV camera used in this type of TV conference system, the resolution of the image is low, so the characters of the document displayed on the display cannot be read, and There was a risk of trouble.

As one method for solving such a problem, it is conceivable to use the zoom function of the television camera to enlarge the angle of view to increase the resolution of the image and photograph an object to be photographed such as a material. However, if the angle of view of the TV camera is expanded beyond a certain level, there is a possibility that it may not be possible to shoot a single image depending on the shooting target. Moreover, it was not possible to deal with objects to be photographed that could not be photographed at once with a TV camera.

As one method for solving such a problem, it is possible to use a digital still camera, which scans an image to capture the image in a computer, in a television conference system. However, the digital still camera cannot capture an image at an arbitrary resolution, which may cause the same problem as described above. Also, although there is a scan analyzer as a device for capturing an image in a computer by scanning the image, the scan scanner cannot be used as a camera and cannot be used in a television conference system.

The present invention has been made in consideration of the above points, and an image processing apparatus capable of obtaining an image with an arbitrary resolution and synthesizing an object to be photographed that cannot be photographed at once as one image, It is intended to propose an image information transmission device using the image processing device.

[0008]

In order to solve such a problem, according to the present invention, the control means controls the drive means to rotate the image pickup means so that an overlapping portion occurs between adjacent image pickup areas. By doing so, an image of the imaging target is picked up, each image information in each image pickup area is stored in the storage unit, and the image processing unit overlaps each image information stored in the storage unit with the adjacent image information. A portion is detected, a display area for each image information is determined based on the detected overlapping portion, image information corresponding to the display area for each image information is combined, and the combined image is displayed on the display means.

Further, according to the present invention, in an image information transmission apparatus having a plurality of terminals and bidirectionally transmitting image information between the terminals, each terminal includes a rotatable image pickup means and an image pickup means. Driving means for rotationally driving, control means for controlling the driving means so that an overlapping portion is generated between adjacent imaging areas when the imaging target is imaged, and each image in each imaging area imaged by the imaging means With respect to the storage means for storing information and each image information stored in the storage means,
An overlapping portion with adjacent image information is detected, a display area of each image information stored in the storage means is determined based on the detected overlapping portion, and image information corresponding to the display area of each image information is combined. Image processing means for displaying, and a display means for displaying the composite image obtained by the image processing means, so that an overlapping portion occurs between adjacent imaging regions,
The control means controls the drive means to rotationally drive the image pickup means to pick up an image of the image pickup object, store each image information in each image pickup area in the storage means, and store the image information in the storage means. For each image information stored in
Detects an overlapping part with adjacent image information, determines the display area of each image information based on the detected overlapping part, synthesizes each image information corresponding to the display area of each image information, and displays the synthesized image Display on the means.

[0010]

The object to be photographed is picked up so that an overlapping portion is generated between the adjacent image pickup areas, the overlapping portion of the image information in each image pickup area is detected, and the detected overlapping portion is detected. The display area of each image information is determined based on the part, each image information corresponding to the display area of each image information is combined, and the combined image is displayed. As a result, it is possible to obtain an image with an arbitrary resolution, and to combine a subject to be photographed that cannot be photographed at once into a single image.

In an image information transmission apparatus having a plurality of terminals and bidirectionally transmitting image information between the terminals, an image of an object to be imaged is picked up so that an overlapping portion is generated between adjacent image pickup areas, and the image pickup is performed. For each image information in each captured area, the overlapping portion with the adjacent image information is detected,
The display area of each image information is determined based on the detected overlapping portion, each image information corresponding to the display area of each image information is combined, and the combined image is transmitted to the partner terminal. As a result, an image with an arbitrary resolution can be transmitted to the partner terminal, and an object to be photographed that cannot be photographed at one time can be combined as one image and transmitted to the partner terminal.
