Note that the camera 51 and the recording device 52 may be directly connected by a telephone line without using the wireless station 53.

Next, the configuration of the camera 51 will be described with reference to the block diagram of FIG. In FIG. 3, an optical lens 1 is an optical system for inputting an image and adjusting a focus, and a diaphragm 2 such as a mechanical diaphragm and a liquid crystal diaphragm is for adjusting an exposure amount. The solid-state imaging element 3 transfers through a photo sensor section that performs photoelectric conversion, a gate section (between the photo sensor and VCCD) that transfers charges accumulated in the photo sensor to a vertical transfer path (VCCD), and the gate section. The vertical transfer path (VCC for transferring the generated charge in the vertical direction)
D), a horizontal transfer path (HCCD) that horizontally transfers the charges transferred from the vertical transfer path, and an output amplifier unit that converts the charges transferred from the horizontal transfer path into a voltage and outputs the voltage to the outside. An unillustrated mechanical shutter, electronic shutter, or the like is provided, and the exposure time is set based on a signal from the photometric element or the solid-state image sensor 3 by controlling the mechanical shutter, electronic shutter, or the like.

The image sensor drive circuit (TG) 4 drives the photosensor section, gate section, vertical transfer path and horizontal transfer path of the solid-state image sensor to control charge transfer. The voice input device 5 inputs a voice and converts it into a voice signal which is an electric signal. The signal processing circuit 6 is a circuit for performing signal processing and may be processed by an analog signal or a digital signal. The voice signal is input from the voice input device 5. Regarding the image signal, when the analog signal is input, it is directly input from the solid-state image sensor 3, and when the digital signal is input, the solid-state image sensor 3 is connected to the A / D converter 7 and a buffer which is a solid-state memory. Input through the memory 8. There are cases where the image signal is stored in the buffer memory 8 and cases where it is output through. Then, the input image signal and audio signal are processed so as to be easily used and converted into a recording signal. That is, if the image is a character, the signal processing circuit 6 converts it into character information, and when the image signal is, for example, a monochrome image signal and the density distribution is biased, it is binarized, and the image signal and the audio signal are digital signals. In some cases, for example, time axis compression is performed. Then, a discrimination signal for discriminating whether the image signal to be transmitted is a binary image, a gradation image, or character information is also added.

The buffer memory 9 is a recording medium drive circuit 14
The output signal of the signal processing circuit 6 or the information demodulated by the modulation / demodulation circuit 10 is stored. There are cases where analog information is stored and cases where digital information is stored. When storing digital information, a solid-state memory such as a memory card is used as the buffer memory 9. When the output signal of the signal processing circuit 6 is processed by an analog signal, it is directly input from the signal processing circuit 6 to the modulation / demodulation circuit 10 without passing through the buffer memory 9. When the output signal of the modulation / demodulation circuit 10, which is an analog signal, is recorded as a digital signal, it is input via the A / D converter 11.
Although it is possible to provide a solid-state memory such as a memory card that can be attached to and detached from the main body and can record, for example, several to several tens of still images, only the minimum necessary buffer memory 9 is provided, The 51 is smaller and lighter. The audio signal stored in the buffer memory 9 is output via the D / A converter 12 and the speaker 13.

The system control circuit 21 may have a function of resetting the signal of the synchronization signal generating circuit to a predetermined phase by an external signal.

Next, the structure of the recording device 52 will be described with reference to the block diagram of FIG. The line controller 31 receives the transmitted information via the cable 17 or the wireless antenna. The modulation / demodulation circuit 32 demodulates the output signal of the line controller 31 and stores it in the buffer memory 33.

The signal processing circuit 34 inputs the image signal and the audio signal stored in the buffer memory 33, separates them into the image signal, the audio signal and the control signal and processes the image signal and the audio signal. Control signal is system control circuit 40
And the entire recording apparatus of FIG. 4 is controlled. The processed image signal and audio signal are also recorded in the recording medium 37. The image signal is output to the monitor TV 35, and the audio signal is output to the audio output device 36 such as headphones, earphones, and speakers. The voice output device 36 and the voice input device 39 may be replaced by a telephone, for example. When the image signal and the audio signal, which are data-compressed using the digital telephone line, are input, the multiplexed image and audio signal are identified and separated by the signal processing circuit 34 and expanded on the time axis. The signal processing circuit 34 is also provided with an image input / output terminal and an audio input / output terminal. From this terminal, for example, an image signal and an audio signal for an external TV monitor, printer, FAX, hard copy, receiver, headphones, etc. I / O is possible.

The recording medium 37 is, for example, a memory card (solid-state memory), a magnetic disk (hard disk, floppy disk, etc.), a magneto-optical disk, etc., and stores image signals and audio signals. The recording medium control circuit 38 controls the recording medium 37 to record the image signal and the audio signal separated by the signal processing circuit 34 on the recording medium 37. Also recording medium
The output control of the image signal and the audio signal recorded in 37 is performed.

The system control circuit 40 incorporates a microcomputer or the like to control the modulation / demodulation circuit 32, the buffer memory 33, the signal processing circuit 34, and the recording medium control circuit 38, and the microcomputer incorporated in the system control circuit 40 controls the system control circuit 40. The receiving means, the signal separating means, and the recording means are configured by software. The control board 41 inputs control information for controlling the device to the system control circuit 40.

Next, the operation of the camera 51 will be described with reference to the flowchart of FIG. In step (denoted as "S" in the figure, the same applies hereinafter) 1, only the necessary circuits are powered on and are in standby. In step 2,
It is determined whether or not the input image is preset as an input as a binary image from the beginning. That is, for example, when a binary image such as a monochrome image is photographed, the input image is manually set to be binarized before the photographing in order to reduce the data amount of the image signal. In this step, the presence / absence of this setting is determined, and if it is preset for binary image input, the process proceeds to step 3, and the threshold level for binarization is set, and the process proceeds to step 4. If the binary image input is not set, the process directly proceeds to step 4.

In step 4, it is determined whether or not a release (not shown) is on. When the release is not on, the process returns to step 1, and when it is on, the process proceeds to step 4. In step 5, it is determined whether or not data is being transmitted. If it is being transmitted, the process proceeds to step 6 to check whether or not the buffer memory 9 is empty. If it is not transmitting, the process proceeds to step 8.

In step 7, since the buffer memory 9 is not empty, a display indicating that photography is not possible is displayed in step 7. In step 8, photometry and distance measurement are performed. The photometry is performed by the photometric device or the solid-state image sensor 3, the aperture value of the diaphragm 2 such as a mechanical aperture and a liquid crystal aperture is controlled by the photometric value, and the exposure time is set to a mechanical surface (not shown) mounted on the front surface of the solid-state image sensor 3. It is controlled by a shutter, an electronic shutter by an image pickup device, or the like. When the light amount is small, the strobe 19 is caused to emit light, the strobe exposure amount is integrated by the integrating circuit 20, and the exposure amount is controlled based on this integrated value.

In step 9, it is judged whether or not the photographing preparation is completed. If the preparation for photographing is not yet completed, the process returns to step 8, and if the preparation is completed, the process proceeds to step 10. In step 10, photographing is performed and the photographed image is processed. The input of a still image is the same as that of a normal video camera.
That is, the image pickup element drive circuit 4 drives the solid-state image pickup element 3 based on the synchronization signal generated by the synchronization signal generation circuit 18, and the photosensor section, the gate section, the vertical transfer path, and the horizontal transfer path in the solid-state image pickup element 3 are driven. Charge transfer is controlled. When the image signal output from the solid-state image sensor 3 is processed by an analog signal, the image signal is directly input to the signal processing circuit 6, and when processed by a digital signal, the A / D converter 7 and the buffer memory 8 are processed. Is input to the signal processing circuit 6 via. When the image signal and the audio signal are transmitted together, the image signal input to the signal processing circuit 6 is converted into a recording signal for easy use together with the audio signal input from the audio input device 5, and the buffer memory 9 is used. Memorized in. When a digital line is used, the signal processing circuit 6 performs time base compression processing on the digitized image and audio signals.

At step 11, it is judged whether or not the photographing is completed. If not, return to step 10,
When finished, go to step 12. In step 12, the input image signal is image-recognized and it is determined whether or not the image is a character. When the photographed image is only characters, the amount of information is reduced by converting the image into a character code. In this case, therefore, the process proceeds to step 13 and the character information processing routine is executed.

Next, the operation of the character information processing routine is shown in FIG.
It will be described based on the flowchart of FIG. In step 21, the image signal is image-recognized and converted into a character code. In step 22, it is determined whether the check of the converted character code is selected. This selection is made manually or automatically, and if it is not checked, this routine is directly terminated. If it is checked, the process proceeds to step 23, and the character based on the character data is compared with the original image. If there is a conversion error as a result of the collation, the character data having the conversion error is corrected. When the check ends, this routine ends.

After executing this character information processing routine, the routine proceeds to step 17. Next, when it is determined in step 12 that the image is not a character, the process proceeds to step 14 and subsequent steps. Step
In steps 14 and 15, a binary image / gradation image is determined for the captured image. That is, when it is determined that the image is a binary image, in step 14, it is determined that the binary image input is preset as in step 2, or in step 15, the density distribution of the captured image is checked. As a result,
For example, it is determined that the image is a binary image such as white and black. In this case, proceed to step 16 and 2
Quantize and proceed to step 17. When it is determined that the image is a gradation image, it is determined that the binary image input is not preset, and it is determined that there is no bias in the density distribution of the captured image. Step 17
Proceed to. In steps 2 to 3 and 12 to 16, the image signal and the audio signal are converted into a transmittable signal, and steps 2 to 3 and 12 to 16 correspond to signal processing means.

In step 17, a control signal is added to the processed image signal and audio signal. The recording device 52 disposed at a position apart from the camera 51 is controlled by this control signal. This step corresponds to the transmission data forming means. In step 18, the image signal and the audio signal are transmitted based on the transmission routine of FIG.

Next, the operation of the transmission routine for transmitting the image signal and the audio signal will be described with reference to the flowchart of FIG. In step 31 of the transmission routine, line connection is made based on the line connection routine of FIG. Next, the operation of this line connection routine will be described based on the flowchart of FIG.

In step 41 of the line connection routine, the line is connected. To connect the line, it is possible to perform the connection manually, or to register the transmission destination in advance and automatically perform it after photographing. When the communication network 54 is used, it is possible to transmit regardless of the usage status of the recording device 52 side. In step 42, it is determined whether or not the line can be connected. If the line cannot be connected, go to step 43.

In step 43, if the line cannot be connected, it is checked whether or not the number of line connection attempts has reached a predetermined number. If the number of times is less than the predetermined number of times, there may be a connection error, so after a predetermined time has elapsed in step 44, the process returns to step 41 and the line connection is executed again. Again step
If the number of trials reaches a predetermined number in 43, it is determined that the line is blocked and the process proceeds to step 45. In step 45, the data is stored in the buffer memory 9 or the like to wait until the line can be connected. Save and exit this routine.

When the line is connected, the process returns from the line connection routine to execute step 32 and the subsequent steps of the transmission routine. In step 32, a transmission start signal is output to the receiving side. The receiving side prepares for the recording state by the transmission start signal.
In step 33, it waits until the receiving side is ready and the transmission permission signal is received.

In step 34, it is judged whether or not the recording preparations on the receiving side have been completed. It is determined that the receiving side is not ready to record until the transmission permission signal is received.
If the transmission permission signal is received, it is determined that the receiving side is ready for recording, and the process proceeds to step 35. In step 35, the transmission data is transmitted. The transmitted data is an image signal,
It is an audio signal and a control signal, and the control signal also includes a discrimination signal of the image signal, and the discrimination signal determines whether the image signal is a binary image / gradation image / character information. Is possible. When the communication network 54 is used, it is transmitted to the communication network 54 in the form of electronic mail, and a detection signal for detecting the transmission is also transmitted.

In step 36, it is judged whether or not the data transmission is completed. Step if transmission is not completed
Returning to step 35, if the transmission is completed, proceed to step 37. In step 37, a transmission end signal is output. In step 38,
The presence or absence of the determination signal output when the receiving side receives the transmission data without error is determined. If the determination signal has not been received, the process returns to step 32 and is re-executed. If the determination signal is received, it is determined that the recording was successful, and this routine ends.

When this transmission routine ends, the routine proceeds to step 19 in FIG. Incidentally, step 18 corresponds to the transmitting means.
In step 19, it is determined whether or not the transmission is completed. If the transmission has not ended, the process returns to step 18, and if the transmission has ended, the process returns from step 19 to step 1 and the standby state is set again for the next transmission.

The line connection routine may be executed immediately after step 1. By doing so, it is possible to transmit the captured image and the recorded voice in real time during a call without worrying about being unable to transmit because the line is blocked. For example, a video of the scene is photographed while reporting the actual condition from the accident scene and the photographed image and voice are transmitted at the same time. In this case, the receiving side also records the received transmission data on the recording medium,
It becomes possible to display the situation of the site on the monitor TV while talking the image.

The recording device 52 receives the transmission data transmitted from the camera 51 in the above operation. Next, the operation of the recording device 52 when inputting the transmission data using the communication network 54 will be described based on the flowchart of FIG. In step 51, the power is turned on and the power is on standby. In step 52, it is determined whether or not the line is connected based on the detection signal notifying that the camera 51 has transmitted the communication network 54. If the line is not connected, the process returns to step 51, and if the line is connected, the process proceeds to step 53. In this case, since the transmission data is transmitted from the camera 51 to the database 55 on the communication network 54 as a transmission file, the recording device 52 accesses the database 55 at a convenient timing.

In step 53, the above-mentioned line connection routine for connecting lines is executed to access the database 55. Receive a send file from the database 55. In step 54, when connected to the communication network 54, the transmission file transmitted from the transmitter side is searched. Step
At 55, check whether there is a file to be sent to yourself. An identification signal is added to the transmission file on the database 55, and the transmission file on the database 55 is identified based on the identification signal. If there is no transmission file, the process returns to step 54 to search for the transmission file again, and if there is a transmission file, the process proceeds to step 56.

In step 56, the transmission file addressed to itself is loaded. The transmission file is input to the line controller 31 via the cable 15, demodulated by the modulation / demodulation circuit 32, and input to the buffer memory 33. In step 57, it is detected whether the load of the transmission file is completed. If it is being loaded, the process returns to step 56, and if it is finished, the process proceeds to step 58.

In step 58, the erasing command is transmitted to the database 55, and the erasing command sends the database.
55 Delete the sent file. In step 59, the transmission data input to the buffer memory 33 as a transmission file is input to the signal processing circuit 34, the transmission data is an image signal,
Separated into audio and control signals. The control signal is input into the system control circuit 40. This step corresponds to the signal separating means.

In step 60, the recording medium control circuit 38 is controlled based on the control signal so that the recording medium 37 receives the image signal,
Record the audio signal. This step corresponds to the recording means. The recording device 52 is remotely operated by a control signal transmitted from the camera 51, but when controlling the recording device 52 on the recording device 52 side, control information is input from the control board 41. The image signal and the audio signal recorded in the recording medium 37 are discriminated that the image signal is any one of a binary image, a gradation image, and character information by the discrimination signal described above. Is processed by the signal processing circuit 34. Further, when the image signal and the audio signal are compressed on the time axis, the signal processing circuit 34 expands the time axis. Then, the image is displayed on the screen of the monitor TV 35, the audio signal is output to the audio output device 36, and is output as audio from the audio output device 36. It is also possible to transmit the image signal and the audio signal recorded in the recording medium 37 to another place by transmitting them via the signal processing circuit 34, the buffer memory 33, and the modulation / demodulation circuit 32.

In step 61, the line is disconnected and the process returns to step 51 to stand by until the next reception. According to this configuration, the camera 51 that captures an image and records a sound and the recording device 52 that records an image signal and an audio signal are provided with a transmission / reception function, and the camera 51 and the recording device 52 are separated from each other. By transmitting the recorded sound from the camera 51 to the recording device 52 and recording it on the recording medium 37, the camera 51 and the recording device 52 can be made smaller and lighter, and the photographed image can be viewed in another place in real time. Can be done. Again camera
By adding a control signal for controlling the recording device 52 to the transmission data transmitted from 51 and transmitting the data, the recording device 52 can be controlled from the camera 51. Further, it is determined whether the image is a non-gradation image such as a black and white image or a character. If the image is a black and white image, the image signal is binarized, and if the image is a character, the image signal is converted. The data amount of the transmission data to be transmitted can be reduced by converting the information into character information and transmitting it.

Communication network 54 such as personal computer communication
By using the database 55 of, the camera 51 side can transmit data from the transmitter side regardless of the usage status of the recording device 52 side, and the recording device 52 side transmits from the communication network 54 at a convenient timing. Can receive data. After receiving the transmission data, the recording device
The transmission data on the database 55 can be automatically deleted by 52. By using the communication network 54 together with the telephone line, the risk that the line cannot be connected due to busy or the like can be eliminated. Further, the camera 51 only needs to be provided with the buffer memory 9, and it is not necessary to mount a recording medium such as a memory card, and the camera 51 can be downsized. If the recording device 52 is a chat phone, it is possible to transmit transmission data such as data notifying that the data has been transmitted to a database on the communication network even during a call.

Next, another system having an image pickup device with a transmission function and a recording device with a reception function will be described. In FIG. 10 showing the second system, a recorder 56 having a receiver is connected to the wireless station 53 via a telephone line or the like,
A receiver 57, a terminal device 58 such as a printer, a fax machine, and a hard copy device, and a monitor TV 59 are connected to the receiver 56. The recorder 56 records the sent image signal and audio signal in a built-in recording device. The voice signal can be output as voice from the handset 57, or headphones (not shown), earphones, spokes, etc., depending on the case. Display the image signal on the monitor TV59,
It is possible to output to the terminal device 58 and take a hard copy of the image signal. The camera 51 may be equipped with a GPS (Global Positioning System) reception function. This makes it possible to recognize position information and time information, and the position information and time information can be recorded from the camera 51 to the recorder.
Can be sent to 56. It is also possible to have a function of automatically calibrating the auto date by inputting, for example, time signal information to the recorder 56 from the handset 56 and recognizing the time information.

In FIG. 11 showing the third system, this system has a structure in which the recorder 56 is provided with a wireless device and the transmission data from the camera 59 is directly received without passing through a wireless station. A terminal device 61 similar to that shown in FIG. 10 is connected to the recorder 60. With this configuration, it is possible to use media other than the telephone line, that is, amateur radio, and police radio for business use. If the transmission capacity of the media is small, it may not be possible to make a call while transmitting the image data. In such a case, a warning is issued from the transmitter to notify the sender, or two or more transmission lines are used to make a call and image transmission at the same time. In the camera 59, 59a is a lens and 59b is an LCD display for displaying various data.
