[Title of Invention] Presentation System

[0001]
[Technical field to which the invention belongs]
The present invention relates to a presentation system.

0005
The document set on the original manuscript platform in When recording taken with the camera, and means for performing positioning and image processing of the camera, the device for transferring and restored by communication video signal, and control means for combining multiple images (See, for example, Patent Document 1) . However, it has only a document camera function for capturing images, and can only be used as a capture device. Further, since the image is divided into four parts, the image data is transferred to the host PC at a remote place by communication, and then the images are combined into one image, processing time and cost are required.
Further, since the deterioration of the image quality due to noise during communication transfer becomes large, high-definition images cannot be transferred.

0006
A photographing camera on a part of the liquid crystal projector, a support arm and an illumination provided, there is for enlarging and projecting the object data such as documents and samples from the projector (e.g., see Patent Document 2). However, in a specific example in which PJ is added to this device and set, it only directly displays the image captured by the document camera, and does not have a function for capturing the image on the screen and detecting the coordinates.

0007
Further, as a document camera, there is a camera that switches between a mode of capturing an image of a platen and a mode of capturing an image of a distant person (see, for example, Patent Document 3). However, the frame rate of the captured image is not considered.

0010
An object of the present invention, immediately digitized data became suddenly required during the presentation (information), excellent operability and usability, presentation system that can perform a smooth and effective presentations Is to provide a system.

[Means for solving problems]
An image input device having an imaging means and
An image processing means for image processing an image pickup signal output from the image pickup means, and an image processing means.
A storage means for storing the image processing result of the image processing means and
It is provided with a display means for displaying the image processing result.
It is characterized by having a drive switching means formed so that the relationship between the image capture rate and the resolution can be changed according to the subject to be imaged.

[0032]
This allows you to use the high-speed shooting mode when you want to shoot at high speed at the expense of resolution, or when you want to prioritize resolution at the expense of high speed, depending on the content and purpose of use of the subject you want to shoot. By changing to the high resolution mode and taking an image, the best imaging conditions can be arbitrarily selected and switched, so that a lean system can be provided that matches the user's intention of use.

0033
An image input device having an imaging means and
An image processing means that performs image processing on the image pickup signal output from the image pickup means,
A storage means for storing the image processing result of the image processing means and
It is equipped with a display means for displaying the image processing result.
The image processing means adjusts the arrangement position of the subject to be imaged in the substantially center of the image pickup area of the shooting based on the image pickup signal.
It is characterized by.

0034
For this reason, not only is it unnecessary to adjust the imaging position, which is normally performed before use, but even if the positional relationship between the imaging means and the display means changes for some reason during use, the image is automatically imaged in the substantially center of the imaging area. Since the means is adjusted, resetting is not required, so that the troublesome adjustments made by the user himself and the individual differences are eliminated, and the usability is improved.
