Field of the Invention The present invention relates to a recording device and a reproducing device suitable for use in, for example, a video camera device, and more particularly to detecting a current position and recording and reproducing this position detection information together with, for example, image pickup information.

2. Description of the Related Art Today, it is easy to carry,
Handy-type video camera devices have come into widespread use because they can easily capture a desired subject. In the handy type video camera device, when image pickup is started, for example, a CCD image sensor receives the image pickup light and performs photoelectric conversion, and forms and outputs an image pickup signal according to the received image pickup light. Further, the video camera device is provided with a timer for counting the current date and time, and when the imaging is started, the timer outputs a date and time signal indicating the current date and time.

Date and time signal from the timer and the CCD
The image pickup signal from the image sensor is supplied to the image pickup signal processing circuit. The imaging signal processing circuit superimposes the date / time signal on the imaging signal, converts the superimposed imaging signal into a format suitable for recording, and supplies the recording / reproducing head and the electronic viewfinder. The electronic viewfinder is provided with a display unit such as a CRT (cathode ray tube), and the display unit is driven according to the superimposed image pickup signal. Therefore, the subject currently being imaged and the current date and time are displayed on the display unit of the electronic viewfinder. The user takes an image while looking at the image displayed on the display unit of the electronic viewfinder.

On the other hand, the sound at the time of this image pickup is collected by the microphone. The microphone converts the collected voice into a voice signal which is an analog electric signal and supplies the voice signal to the PCM processor. The PCM processor converts the analog audio signal into, for example, 10-bit digital data, performs predetermined modulation to form PCM audio data, and supplies the PCM audio data to the recording / reproducing head.

The recording / reproducing head is a rotary head, and records recording information by a so-called helical scan method. Recording information is supplied to the recording / reproducing head in the order of, for example, the PCM audio data and the superimposed image pickup signal. Therefore, for example, 8
First, the PCM audio data is recorded on a mm-width video tape, and following this PCM audio data, the superimposed imaging signal of one field is recorded as one track. The PCM audio data is digitally recorded, and the superimposed image pickup signal is analogly recorded.

The superimposed image pickup signal and the PCM audio data recorded in this way are reproduced by the recording / reproducing head. When the recording / reproducing head is in reproduction, the P
A track on which the CM audio data and the superimposed image pickup signal are recorded is traced. As a result, the PCM audio data and the superimposed image pickup signal recorded on the video tape are sequentially reproduced.

The PCM audio data reproduced by the recording / reproducing head is supplied to the DPCM processor. The DPCM processor performs a predetermined demodulation process on the PCM audio data, and supplies this to the audio processing circuit. The audio processing circuit forms an audio signal by converting the PCM audio data demodulated by the DPCM processor into an analog signal and supplies the audio signal to a speaker device or the like via an audio signal output terminal. As a result, a sound at the time of the image pickup is sounded from the speaker device.

The superimposed image pickup signal reproduced by the recording / reproducing head is supplied to an image pickup signal processing circuit. The image pickup signal processing circuit subjects the image pickup signal to image pickup signal processing that conforms to, for example, the so-called NTSC format, and outputs the signal. The image pickup signal output from the image pickup signal processing circuit is supplied to, for example, a monitor device or the like via the electronic viewfinder and the superimposed image pickup signal output terminal. As a result, an image corresponding to the reproduced superimposed image pickup signal is displayed on the display unit of the electronic viewfinder and the monitor device.

As described above, since the superimposed image pickup signal includes the image pickup signal of the image of the subject and the date and time information from the timer, the image of the subject and the subject are picked up on the display section. The date and time will also be displayed. Therefore, the user can easily recognize the date and time when the subject is imaged.

Now, in recent years, so-called GPS
A device called (Global Positioning System) that measures and displays the current position is known. This GPS
Will eventually cover the entire globe with 18 satellites, 3 in 6 orbits. Each satellite is launched into a circular orbit with an orbital altitude of about 20180 km, an orbital tilt angle of 63 °, and a period of about 12 hours, so that four or more satellites can be seen from anywhere on the earth at any time.

The GPS measures the current position by three-dimensional positioning by passive distance measurement from the four satellites (a method in which the user measures the distance from the satellite only by receiving radio waves without transmitting the radio waves). Is supposed to do. Therefore, each satellite is provided with an atomic clock using a rubidium oscillator or a celsium oscillator. The stability of this watch is 10 ^-13 , which is an extremely precise error of 1 second every 300,000 years.

Now, assuming that the user also has an accurate clock such as the atomic clock described above, and the time is completely in agreement with the time of the satellite clock, the time signal from the satellite is received. , By comparing it with the time on the user side,
The radio wave propagation time from the satellite to the user, that is, the distance can be measured. With such a method, the user's three-dimensional position can be determined by measuring the distances from three satellites whose positions are known. However, the user can use an expensive clock such as the atomic clock described above. It is almost impossible economically to have.

For this reason, in GPS, the user uses an inexpensive clock such as a quartz clock, and instead, in order to remove the error of this clock, distance measurement is performed from another satellite. That is, due to recent advances in satellite tracking technology, the positions of GPS satellites are known very accurately, and their orbit information is constantly transmitted from the satellites. The user's receiver receives the orbit information from four satellites, calculates the position of each satellite from the orbit information, and performs the passive distance measurement described above to determine the three-dimensional position of the user. Can be measured.

[0014]

However, the above video camera device can record the image pickup date and time, but cannot record the image pickup place. For this reason, even if the image recorded later is viewed, it is difficult to know where it was captured. In order to prevent such an inconvenience, it is sufficient to check the place where the image is taken with a map or the like and write it down every time the image is taken, but this is very troublesome. .

As described above, the GPS is currently used.
Devices that can accurately measure the current position, such as, are becoming popular. Therefore, it is desired to develop a recording / reproducing device capable of recording / reproducing the current position measured by the GPS.

The present invention has been made in view of the above-mentioned problems, and the recorded position can be easily recognized by recording and reproducing the current position measured by the GPS together with the image and the sound. An object is to provide such a recording device and a reproducing device.

As a result, the image pickup signal is supplied to the monitor device via the image pickup signal output terminal 26, and an image corresponding to the image pickup signal is displayed on the monitor device.

When the position data is displayed by being superimposed on the image pickup signal, the changeover switch 28 is turned on. As a result, the character image pickup signal from the reproduction character generator 23 is supplied to the adder 24. The adder 24 forms a superimposed image pickup signal by superimposing the character image pickup signal on the image pickup signal, and supplies this to the monitor device via the image pickup signal output terminal 26. As a result, the position at which the image is picked up is visualized as characters or the like and displayed on the monitor device together with the image corresponding to the image pickup signal.

Thus, it is possible to easily recognize the image pickup location without performing a troublesome work such as checking the image pickup location on a map or the like and writing it down.

As is clear from the above description, the recording / reproducing apparatus according to the present embodiment measures the current position by using a device such as GPS which can measure the current position, and uses this position data as an image pickup signal. Superimpose and record, or PC
By recording and playing with M audio data,
It is possible to easily record and reproduce the place where the image is taken and the like. For this reason, when confirming the imaging location later, it is possible to easily confirm the imaging location.

Incidentally, by separately providing the reproducing character generator 23 and the adder 24 provided in the reproducing system 3 in an external form, the position data is imaged without changing the circuit structure of the reproducing system. It can be displayed superimposed on the signal.

Finally, the technical idea of the present invention is to detect the current position and record the current position information indicating the detected current position in the recording medium together with the image pickup signal. Therefore, the position detection means is not limited to the configuration of the above-described embodiment, and instead of the GPS, for example, position information from a transmission pole embedded in the ground that transmits the position information of the position is detected. As long as it is possible to detect the current position, such as using a device that measures the current position, various modifications can of course be made without departing from the above technical idea. is there.
