Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a block diagram showing a configuration for initializing a recording medium of an imaging apparatus according to a first embodiment of the present invention. Here, the overall configuration of the imaging apparatus is the same as that of FIG. 9, and FIG. 1 shows only members necessary for describing the present invention.

A recording medium 6 such as a floppy disk or an IC card is mounted on the recording section 4 of the image pickup apparatus. The recording unit 4 includes a signal line 7 for transmitting a detection signal,
The recording medium 6 is connected to the control unit 5 by a signal line 8 for transferring a format command for executing the format.

The operation of executing the format of the imaging apparatus having the above configuration will be described with reference to the flowchart of FIG.

First, a floppy disk or I
The recording medium 6 such as a C card is inserted (step S1).
Then, the recording section 4 detects whether or not the mounted recording medium 6 has an index, that is, whether or not the recording medium 6 is formatted, and sends a detection signal to the control section 5 via the signal line 7 ( Step S2). Here, when it is determined that there is no index (not formatted) (NO), the control unit 5 transfers a format command to the recording unit 4 via the signal line 8 and the recording medium 6
Is performed (step S3). However, when it is determined that the data has been formatted (YES), or after the data has been formatted in step S3, the recording unit 4 enters a data input enabled state (step S4). Then, the control section 5 sends out the digitized compressed data from the preceding compression section (not shown) and records it on the recording medium 6.

However, if data of an analog signal is recorded on a floppy disk or the like and the data is erroneously inserted, the formatting is executed, and at that time, the data of the analog signal is also deleted.

Therefore, in order to prevent erroneous erasure, it is necessary to detect three states of analog recording, digital recording and unformatted, and to format according to the state.

FIG. 2 shows a configuration of a second embodiment in which the above-mentioned three format states are detected and if the format state is not yet established, formatting is performed.
Here, FIG. 2 shows only the members necessary for explaining the present invention of the image pickup apparatus as in the first embodiment, and the overall configuration of the apparatus is the same as FIG. The recording medium will be described using, for example, the floppy disk 6a.

The floppy disk 6a is provided with an index mark hole, and an index signal is written with the index mark hole as a reference position. In the analog format index signal, a synchronization signal, a track number, and the like are recorded as a digital signal.

In the structure of the image pickup apparatus, first, the floppy disk 6a is inserted into the recording section 4 and mounted. Then, the index signal of the floppy disk 6a is detected by the header 9 of the recording section 4 and read into the discriminating circuit 11. The analog index recording section 10 inputs a previously recorded index signal to the discrimination circuit 11 under the control of the control section 5. Then, the discrimination circuit 11 sends a result of discrimination between these two index signals to the control unit 5.

Similarly, the index signal is read from the floppy disk 6a to the discriminating circuit 11, and the digital index recording unit 12 controls the index signal stored in advance in the discriminating circuit 11 under the control of the control unit 5.
To enter.

Then, the result of determining the correlation between these index signals is sent to the control unit 5.

Next, the operation of the format of the imaging apparatus configured as described above will be described with reference to the flowchart of FIG.

First, the floppy disk 6a is stored in the recording unit 5
(Step S11).

Next, the disk of the floppy disk 6a is rotated, and only the index signal written on the floppy disk is read into the discriminating circuit 11 via the header 9 in synchronization with the cycle of the index mark hole.
At this time, the data recording portion of the floppy disk 6a where the analog data is recorded is subjected to a masking process so as to be fixed at a certain value, and only the index signal is extracted. When reading the index signal, the determination circuit 11 reads the index signal recorded in the analog index recording unit 10.

The determination circuit 11 determines whether or not the correlation between the two analog index signals is high.
(Step S12). If the correlation of the analog index signal is high (YES), it is determined that the analog index has already been recorded, and the floppy disk 6a is ejected (step S13).

When the correlation of the analog index signal is low, it is determined that there is no analog index, and the same operation as the reading of the analog index signal is repeated for the digital index signal.

That is, the index signal read from the floppy disk 6a and the index signal from the digital index recording section 12 are read, and the presence or absence of a digital index is determined based on the correlation between these digital index signals (step S14). Here, when it is determined that the digital index signal has a high correlation and there is a digital index (YES), the recording unit 4 in a step S16 described later enters a standby state in which data can be input. When it is determined that the correlation of the digital index signal is low and there is no digital index (not formatted) (NO),
The control unit 5 transfers a format command to the recording unit 4 and executes formatting of the floppy disk 6 (step S15), and the recording unit 4 enters a standby state in which data can be input (step S16).

In this embodiment, when the analog index is recorded, the disc is ejected. However, the user may be asked to determine whether to execute the format.

Next, FIG. 5 shows the configuration of an image pickup apparatus according to a third embodiment of the present invention. Here, FIG. 5 shows only the members necessary for explaining the present invention of the image pickup apparatus as in the first embodiment, and the entire configuration of the apparatus is equivalent to FIG. The description will be made using the IC card 6b as a recording medium.

In the configuration of the imaging apparatus, first, the I
The C card 6b is inserted into the recording unit 4 and mounted. Then, an index signal is detected from the IC card 6b,
The digital index recording unit 12 inputs the index signal to be recorded in advance to the discrimination circuit 11 under the control of the control unit 5 while reading into the discrimination circuit 11.

The discrimination circuit 11 discriminates the correlation between these index signals, and outputs the result to the control unit 5.
To send to.

Next, the format operation of the image pickup apparatus according to the third embodiment having the above-described configuration will be described with reference to the flowchart of FIG.

First, the IC card 6b is inserted into the recording section 5 (step S21). Then, only the digital index signal is extracted from the IC card 6b, and the previously recorded index signal is read from the digital index recording unit 12.

That is, the index signal read from the IC card 6b and the digital index recording unit 12
An index signal is read from the memory, and the presence or absence of a digital index is determined based on the level of correlation between these digital index signals (step S23). Here, when it is determined that the digital index signal has a high correlation and there is a digital index (YES), the recording unit 4 in step S27 described later enters a standby state in which data can be input.

When it is determined that the correlation of the digital index signal is low and there is no digital index (no format) (NO), the result is displayed on the display unit 13 (step S23), It is determined whether or not to write the digital index on the IC card 6b (step S24). Here, if it is not necessary for the user to write the digital index into the IC card 6b (execute the format) (N
O), the IC card 6b is ejected (Step S2)
5). However, if the user writes a digital index (executes formatting) on the IC card 6b, the control unit 5 transfers a format command to the recording unit 4 and executes formatting of the IC card 6b ( In step S26), the recording unit 4 enters a standby state in which data can be input (step S27). When no index is recorded in the IC card, the format may be automatically executed.

Next, FIG. 7 shows the configuration of an image pickup apparatus according to a fourth embodiment of the present invention. As described above, only members necessary for describing the present invention of the imaging device are shown.

In the configuration of the image pickup apparatus, first, the recording medium 6c is inserted into the recording section 4 and mounted. Then, an index signal is detected from the recording medium 6c and sent to the determination circuit 11.

A plurality of digital index recording units 14 to 16 in which different operation systems (DOS) are recorded are arranged in parallel in the discrimination circuit 11, and each of them is recorded in advance by the control of the control unit 5. The index signal to be input is input to the determination circuit 11.

Next, the formatting operation of the imaging apparatus according to the fourth embodiment configured as described above will be described with reference to the flowchart of FIG.

First, the recording medium 6c is inserted into the recording section 4 (step S31). Then, only the digital index signal is extracted from the recording medium 6c and sent to the determination circuit 11. At the same time, the pre-recorded index signal is sequentially read from the digital index recording units 14 to 16 and the pre-recorded digital index is transmitted. The discrimination circuit 11 receives the digital index signal from the recording medium 6c,
By comparing with the index signals recorded in advance from the digital index recording units 14 to 16, if there is an index (YES), it is determined that the index is already recorded (steps S32 to S35). ), The recording medium 6c is discharged (step S33).

If all the digital indices are not found in the discrimination circuit 11 (NO), the control unit 5 transfers a format command to the recording unit 4 to execute the formatting of the recording medium 6c. Then, the recording unit 4 enters a standby state in which data can be input (step S37).

Such an image pickup apparatus is provided with digital index recording units of the same number as the types of DOS with the diversification of the disk operation system (DOS), and can cope with the diversification of DOS. is there.

The imaging apparatus having the above-described configuration can automatically perform complicated operations for formatting a recording medium by automatically determining the presence or absence of the format and performing the formatting.
Further, in the imaging apparatus of the present invention, since the recording medium is mounted on the imaging apparatus itself and is formatted, it is not necessary to separately provide a formatting apparatus, a personal computer, and the like.

Therefore, the image pickup apparatus of the present invention can detect the presence or absence of a format when a recording medium is mounted on the image pickup apparatus, and can automatically execute an appropriate format corresponding to the state.

The present invention is not limited to the above-described embodiment, and it goes without saying that various modifications and applications can be made without departing from the scope of the invention.
