In order to achieve the above object, the present invention has an image pickup means for picking up an image, a conversion means for predetermined conversion of an image signal sent by the image pickup means into a digital signal, and a predetermined conversion. When a recording medium for recording the image signal is attached, the discriminating means discriminates the format state of the recording medium, and when the discriminating means discriminates that the recording medium is not in the predetermined format, a preset operation is performed. Provided is an image pickup apparatus comprising: a recording unit that initializes the recording medium and records a predetermined converted image signal on the recording medium when it is determined that the recording medium is in a predetermined format and when the initialization is completed. can do.

[0011]

According to the image pickup apparatus having the above-mentioned structure, when the recording medium is mounted on the image pickup apparatus, the recording unit detects the presence or absence of the format, and when the recording medium is not formatted,
The image pickup device can automatically perform a predetermined initialization operation.

[0012]

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

FIG. 1 is a block diagram showing a structure for initializing a recording medium of an image pickup apparatus according to the first embodiment of the present invention. Here, the overall configuration of the image pickup apparatus is equivalent to that of FIG. 9, and FIG. 1 shows only the members necessary for explaining the present invention.

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

The operation of executing the format of the image pickup apparatus thus configured 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 unit 4 detects whether or not the mounted recording medium 6 has an index, that is, whether or not it is formatted, and sends the detection signal to the control unit 5 via the signal line 7 ( Step S2). When it is determined that there is no index (not formatted) (NO), the control unit 5 transfers the format command to the recording unit 4 via the signal line 8 and the recording medium 6
Is formatted (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 is in a data input ready state (step S4). Then, the control unit 5 causes the compression unit (not shown) in the preceding stage to send out the digitized compressed data and record it on the recording medium 6.

However, when analog signal data is recorded on a floppy disk or the like, if it is inserted by mistake, formatting is executed and the analog signal data is also erased at that time.

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

FIG. 2 shows the configuration of the second embodiment in which the above-mentioned three format states are detected, and if they are in the unformatted state, the format 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 entire configuration of the apparatus is the same as that of FIG. 9. The recording medium will be described using the floppy disk 6a, for example.

An index mark hole is provided in the floppy disk 6a, and an index signal is written with the index mark hole as a reference position. The index signal in the analog format has a sync signal, a track number, etc. recorded as a digital signal.

In the construction of this image pickup device, the floppy disk 6a is first 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 discrimination circuit 11. Further, the analog index recording unit 10 inputs the prerecorded index signal to the discrimination circuit 11 under the control of the control unit 5. Then, the discrimination circuit 11 sends the discrimination result of these two index signals to the control unit 5.

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

First, the floppy disk 6a is attached to 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 through 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 on which the analog data is recorded is masked to fix it to a certain value so that only the index signal is extracted. When reading the index signal, the discrimination circuit 11 reads the index signal recorded in the analog index recording unit 10.

Then, it is determined whether the correlation between these two analog index signals is high or not.
Is determined (step S12). Here, when 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 are read from the digital index recording section 12, and the presence or absence of a digital index is determined based on the degree of correlation between these digital index signals (step S14). 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 S16 described later is in a standby state in which data can be input. When it is determined that the digital index signal has low correlation 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).

Further, in the present embodiment, when the analog index is recorded, the disc is ejected, but the user may be asked to judge the execution of the format.

Next, FIG. 5 shows the arrangement of an image pickup apparatus according to the 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 the same as that of FIG. 9. Further, the IC card 6b will be described as a recording medium.

In the configuration of this image pickup apparatus, first, the above-mentioned I
The C card 6b is inserted into the recording unit 4 and attached. Then, the 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 being read into the discrimination circuit 11.

Then, the discrimination circuit 11 discriminates the correlation of these index signals, and the result is discriminated by the control unit 5.

Next, the format operation of the image pickup apparatus of the third embodiment configured as described above 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 index signal recorded in advance 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 section 12
Further, the index signal is read, and the presence or absence of the digital index is determined based on the correlation between these digital index signals (step S23). 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, which will be described later, is in a standby state in which data can be input.

When it is determined that the digital index signal has a low correlation and there is no digital index (not formatted) (NO), the result is displayed on the display unit 13 (step S23), and the result is displayed by the user. Determines whether to write the digital index in the IC card 6b (step S24). If it is unnecessary for the user to write the digital index (execute the format) in the IC card 6b (N
O), the IC card 6b is ejected (step S2)
