Material presentation device
A material presentation device connecting at least two material presentation devices to each other, comprises a first selecting device for selecting one image as a main image from plural images composed of an image output by another material presentation device, a camera image of a material on a material mounting pedestal, which is photographed by a photographing section, an image stored in a memory device, and an external image output by an external device connected thereto, a second selecting device capable of selecting no image or one image as an additional image from plural images composed of a camera image of a material on the material mounting pedestal, which is photographed by the photographing section, an image stored in the memory device and an external image output by the external device, a point image generating device for generating a point image from point information which is subtracted from an image photographed by the photographing section, an image synthesizing section for synthesizing the additional image selected by the second selecting device and the point image with the main image selected by the first selecting device, a display image selecting device for selecting one image from an image output by another material presentation device and the image synthesized by the image synthesizing section, an image displaying section for displaying the image selected by the display image selecting device, and an image outputting section for outputting the image synthesized by the image synthesizing section.
1. A material presentation device connecting at least two material presentation devices to each other, comprising:
a material mounting pedestal having a material mounting surface on which material is mounted;
a photographing section for photographing the material;
a first selecting device for selecting one image as a main image from plural images composed of an image output by another material presentation device, a camera image of a material on the material mounting pedestal, which is photographed by the photographing section, an image stored in a memory device, and an external image output by an external device connected thereto;
a second selecting device capable of selecting no image or one image as an additional image from plural images composed of a camera image of a material on the material mounting pedestal, which is photographed by the photographing section, an image stored in the memory device and an external image output by the external device;
a virtual screen which is set on the material mounting surface;
a pointing mark for setting the virtual screen and for being used by a user to operate a point on the virtual screen;
a point image generating device for generating a point image from point information which is subtracted from an image of the virtual screen and the pointing mark photographed by the photographing section;
an image synthesizing section for synthesizing the additional image selected by the second selecting device and the point image with the main image selected by the first selecting device;
a display image selecting device for selecting one image from an image output by another material presentation device and the image synthesized by the image synthesizing section;
an image displaying section for displaying the image selected by the display image selecting device;
an image outputting section for outputting the image synthesized by the image synthesizing section; and
an optical filter which is removably provided to the photographing section and which enables the photographing section to photograph only light emitted from the pointing mark,
wherein when the user sets two arbitrary reference points by using the pointing mark on the material mounting surface, the photographing section photographs the two reference points, and coordinates on the virtual screen are generated by an image processing technique from a photographed image of the two arbitrary reference points photographed by the photographing section, so that the virtual screen is set to have a rectangular area based on the two arbitrary reference points.
2. A material presentation device connecting at least two material presentation devices to each other, comprising:
a material mounting pedestal having a material mounting surface on which material is mounted;
a photographing section for photographing the material;
a selecting device for selecting one image as a main image from plural images composed of an image output by another material presentation device, a camera image of a material on the material mounting pedestal, which is photographed by the photographing section, an image stored in a memory device, and an external image output by an external device connected thereto;
a virtual screen which is set on the material mounting surface;
a pointing mark for setting the virtual screen and for being used by a user to operate a point on the virtual screen;
a point image generating device for generating a point image as an additional image from point information output by another material presentation device and point information which is subtracted from an image of the virtual screen and the pointing mark photographed by the photographing section;
an image synthesizing section for synthesizing the main image selected by the selecting device with the additional image generated by the point image generating device;
an image displaying section for displaying the image synthesized by the image synthesizing section;
a first outputting section for outputting the main image which is selected from plural images composed of the camera image of a material on the material mounting pedestal, which is photographed by the photographing section, the image stored in the memory device, and the external image output by the external device connected thereto;
a second outputting section for outputting point information which is subtracted from the image photographed by the photographing section;
a first inputting section for inputting the main image which is output by the first outputting section of another material presentation device;
a second inputting section for inputting point information which is output by the second outputting section of another material presentation device; and
an optical filter which is removably provided to the photographing section and which enables the photographing section to photograph only light emitted from the pointing mark,
wherein when the user sets two arbitrary reference points by using the pointing mark on the material mounting surface, the photographing section photographs the two reference points, and coordinates on the virtual screen are generated by an image processing technique from a photographed image of the two arbitrary reference points photographed by the photographing section, so that the virtual screen is set to have a rectangular area based on the two arbitrary reference points.
