Description

Subject input and remote transmission / reception system by digital camera {SYSTEM FOR SUBJECT INPUT AND REMOTE TRANSCEIVER IN DIGITAL CAMERA}

The present invention relates to a subject input in a planar state by a digital camera and a transmission / reception system thereof.

Conventionally, since it is necessary to hold the camera in hand to capture the subject, it is difficult at this time to accurately position the image due to the shaking of the hand, and the data obtained in this way has to receive data by connecting the camera and the computer by wire in order to informatize the information on the computer. It is cumbersome, and it is difficult to adjust the position when photographing a flat subject, and a conventional scanner cannot input a three-dimensional subject. The hassle of connecting the computer and the camera by wire and the disadvantage of carrying the connection cable in the portable terminal always.

Accordingly, an object of the present invention is to provide a subject input system by a digital camera of a complex type that can input data to a camera by infrared communication in inputting three-dimensional subject data such as through a scanner.

Another object of the present invention is a camera-type input device, but any subject can be input, but the main subject is a plane-type subject (paper, paper, etc.), and there is no difficulty to adjust the position of the existing paper surface for this purpose. The present invention provides a subject input system that enables input of all subjects, and transmits or receives data obtained in this way to a remote counterpart via IR (infrared ray) communication.

The present invention for performing the above object is a first means for easily aligning the position of the paper surface when inputting a subject in the form of documents, such as documents, and transmitting and receiving the data obtained by the first means with a computer through infrared communication A first process of integrating a digital camera by the first means for inputting a flat object such as a document in the first means to simplify the operation on a monitor on a computer, In the first process, a second process of integrating an infrared transmitting and receiving device to enable infrared communication is made, so that data can be transmitted and received through infrared communication with various computers in the room, thereby providing an existing network to a remote party. It is composed of a system that can transmit information by using.

In order to eliminate the difficulty of aligning the position of the document or the paper 101, the operation of the digital camera 103 is easily mounted on the scanner 105 so as to enable input of a signal of a subject in a flat form. An infrared ray transmitter / receiver 107 is configured to enable wireless communication with respect to data.

It is composed of an integrated information communication network (ISDN) 202 that receives the telephone modem unit 201 and switches it to be transmitted to the remote personal computer 203.

3 is a detailed circuit diagram of the infrared transceiver 107 of FIG.

A digital modulation circuit 302 for inputting the scanned data and digitally modulating and outputting the scanned data;

An infrared light emitting diode (LED) for converting the output of the digital modulation circuit 302 into an infrared light signal and transmitting it wirelessly;

A photodiode (PD) for receiving an infrared radio signal of document data of the infrared light emitting diode (LED);

An amplifier 303 for amplifying the output of the photodiode PD;

A band pass filter 305 for filtering the output of the amplifier 303 to pass only within a predetermined band;

A comparator 306 for comparing the output of the band pass filter 305 at a predetermined level;

And a digital demodulation circuit 307 for demodulating the output of the comparator 306 into digital data.

Therefore, a specific embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3.

By removing the difficulty of aligning the position of the document paper 101 or the like as in the example of FIG. 1, the operation can be easily mounted by attaching the digital camera 103 to the scanner 105 to enable input of a subject in a flat form. The infrared transmission / reception unit 107 processes the obtained data and transmits the data to a remote terminal. That is, a method of transmitting information to a remote terminal by connecting to a public telephone line using an existing connection cable. However, there are limitations on the usage environment, such as having to carry an adapter such as a cable or a modem 204 at all times. However, the infrared transmission / reception unit 107 allows connection without a connection cable through a portable terminal. It is not necessary to carry it, and it connects to the existing comprehensive information communication network 202 and communicates data to the counterpart of the remote personal computer 203. In addition, when several people use the same place in advance, when performing the infrared communication by setting the order of each terminal in advance, it is possible to simultaneously and simultaneously at a short distance without data collision. The input is received by the digital modulation circuit 302 and modulated to communicate wirelessly with infrared light through a light emitting diode (LED). The signal transmitted to the infrared light is received by a photodiode (PD) and amplified by the amplifier 303. The output of the amplifier 303 is passed through the band pass filter 305 in a predetermined band, and is output by comparing it with the reference level by the comparator 306, and then demodulated and transmitted by the digital demodulation circuit 307. For example, if a personal computer printer or a facsimile is used as a combination of 1,2, the information may be transmitted to a remote party through infrared communication at a short distance. In the existing copier, as shown in FIG. 1, when the camera 103 is mounted and subjected to infrared communication, the data copied with the copier is copied to paper, the camera 103 is photographed again, and the data is connected to the personal computer by wire. You can send data directly to a remote party without having to send it.

As described above, a three-dimensional subject such as a scanner is a complex type in which a three-dimensional subject can input data to a camera by infrared communication, which has to be connected by wire to improve a problem in which data cannot be input. There is an advantage of providing a subject input device by a digital camera.
