Such a magnetic disk usually has 52 tracks, and video or audio is recorded on the 1st to 50th tracks. The 52nd track is an optional cue track, and can be used to record codes for correctly combining video and audio, if necessary.

Note that nothing is recorded on the 51st track.

[Problem to be solved by the invention]

When shooting with an electronic still camera, you can obtain the desired image by freely combining exposure, aperture, and shutter speed, just like with a silver halide camera.
It is also possible to perform various operations such as zooming. However, when a camera becomes multifunctional in this way, the problem arises that not only the operation mechanism such as operation buttons provided on the camera body becomes complicated, but also the operation becomes complicated.

The present invention provides a magnetic disk that can realize various controls for an electronic still camera that only has a simple operation mechanism, and that allows the photographer to accurately recognize the details of the control, and a magnetic disk that allows the photographer to accurately recognize the details of the control. The purpose of the present invention is to provide an electronic still camera controlled by an electronic still camera.

It is characterized in that information indicating the type of the recording track is stored, and means is provided for associating the control data stored in the first recording track with the information stored in the second recording track. Further, the electronic still camera according to the present invention is characterized in that this magnetic disk is attached. The information stored in the second recording track may be audio or video.

〔Example〕

The present invention will be explained below with reference to illustrated embodiments.

FIG. 1 shows a control circuit built into an electronic still camera according to an embodiment of the invention, and FIG. 2 shows a magnetic disk according to an embodiment of the invention.

The system controller 11 is a conventionally known microcomputer that controls the entire camera, and includes CPU, ROM, and RA.
Various operation switch groups 12 are connected to this system controller 11. The image of the subject is
A solid-state image sensor (CCD) 1 is formed by an aperture and a lens 14.
5. The CCD 15 is connected to a video processing circuit 17 via an imaging circuit 6, and the imaging circuit 16 and video processing circuit 17 are connected to and controlled by the system controller 11. Note that the aperture drive circuit 1
3 is also connected to the system controller 11, and is driven and controlled by the system controller 11 based on information from a distance measuring means (not shown).

The image formed on the CCD 15 is input to the image processing circuit 17 via the imaging circuit 16. This video processing circuit 1
In 7, the video signal input from the imaging circuit 16 is
It is divided into a color difference signal and a luminance signal, and two color difference signals (
RY, B-Y) are arranged alternately every IH (horizontal scanning period). The video processing device 17 is also connected to a video output terminal 18, and by connecting a playback device (not shown) to this terminal 18, it is possible to view the shot video.

The white balance sensor 21 is connected to the system controller 11 via a white balance processing circuit 22, thereby correcting the color tone of the image obtained by shooting.

The disk device includes a magnetic head 31 and this magnetic head 3.
1, a spindle motor 33 for rotationally driving the magnetic disk D, a motor drive circuit 34 for driving and controlling this motor 33, and a PG coil for detecting the rotational angular position of the magnetic disk D. 35. The PC coil 35 is connected to a motor drive circuit 34, and the motor drive circuit 34 and head drive circuit 32 are connected to the system controller 11.

The luminance signal and two color difference signals of the video signal are each subjected to FM modulation, and data such as the shooting date is subjected to DPSK modulation and multiplexed recording is performed on the same recording track. For this purpose, an FM modulation circuit 4 and an FM demodulation circuit 42 are connected to the video processing circuit 17, and a DPSK modulation circuit 47 and a DPSK demodulation circuit 49 are connected to the system controller 11.

The FM modulation circuit 41 includes a head amplifier 43 and a switch 4.
4, the FM demodulation circuit 42 also connects to the head amplifier 45.
and a switch 44, respectively, to the magnetic head 31 of the disk device.

A DPS is connected between the FM modulation circuit 41 and the head amplifier 43.
A K modulation circuit 47 is connected, and a low pass filter (LPF) 48 is connected between the FM demodulation circuit 42 and the head amplifier 45.
A DPSK demodulation circuit 49 is connected thereto.

The switch 44 is configured to be selectively switched between the FM modulation circuit 41 side and the FM demodulation circuit 42 side under the control of the system controller 11. That is, when recording video data on the magnetic disk D, the switch 44 connects the head amplifier 43 of the FM modulation circuit 41 to the magnetic head 31, whereby the video data is FM modulated.
Further, data such as the date of photographing is DPSK-modulated and recorded on the magnetic disk D. On the other hand, when reproducing video recorded on the magnetic disk D, the switch 44 connects the head amplifier 45 of the FM demodulation circuit 42 to the magnetic head 31. Therefore, the video data recorded on the normal magnetic disk D is FM demodulated and inputted to the video processing circuit 17, whereby the video is played back by the playback device connected to the video output terminal 18. Further, data such as the date of photography is DPSK demodulated and input to the system controller 11, whereby the date of photography and the like are reproduced together with the video.

As will be described later, the magnetic disk D in this embodiment stores photographing control data such as F value and shutter speed, and there is a link between the FM demodulation circuit 42 and the head amplifier 45 for reading this photographing control data. A data reading circuit 46 is connected thereto. The data reading circuit 46 is connected to the system controller 11, and the imaging control data is analyzed by the system controller 11.
This controls the camera's photographing operation and the like.

Now, the magnetic disks installed in the disk device include a conventional magnetic disk (hereinafter referred to as a normal disk), which is for recording images, and a magnetic disk of this embodiment, which stores shooting control data. things (hereinafter,
(called a data disk). Therefore, the contents recorded on the tracks differ depending on whether the magnetic disk is a regular disk or a data disk, and the circuits that operate also differ accordingly. There is no need to determine. This is because the configuration is such that only a predetermined circuit is activated depending on the type of reproduction signal from the magnetic helad 31.

Note that a display device 51 is connected to the system controller 11 for displaying the current status of the camera and the like.

FIG. 2 shows a magnetic disk D. This magnetic disk D has the same appearance as a 2-inch magnetic disk used in a typical electronic still camera, and has 52 tracks. In a normal disc, the 1st to 50th tracks d from the outside are recording tracks for recording digital data such as video, audio, and shooting date.
Nothing is recorded on the 52nd track, and the 52nd track C is a cue track on which a so-called cue signal is recorded. However, in the magnetic disk D of this embodiment, the recording track d stores photographing control data such as the F value and shutter speed, and the cue track C
Stores information indicating that this magnetic disk is a disk that stores photographing control data, that is, a data disk.

FIG. 3 shows a program diagram that is an example of this imaging control data. That is, this photographing control data indicates the relationship between the F value and the shutter value using the EV value as a parameter, and is indicated by a solid line S. Although only one program diagram is shown in this figure, a plurality of diagrams as shown by this solid line S are stored in the magnetic disk of this embodiment. On the other hand, system controller 11
A program diagram indicated by a broken line is stored in the ROM as basic imaging data.

FIG. 4 shows the format of the photographing control data stored in the recording track. This control data is arranged by repeating the EV value, F value, and shutter value, and one point on the solid line S in FIG. 3 is represented by this set of EV value, F value, and shutter value.

FIG. 5 is a flowchart showing a first embodiment of the preparation operation for photographing in an electronic still camera.

In step 101, a magnetic disk is inserted into the disk device of the electronic still camera, and in step 102, data on the cue track of this magnetic disk is read out. In step 103, based on the data read out in step 102, it is determined whether the currently loaded magnetic disk is a data disk, that is, whether photographing control data is stored in this magnetic disk. Here, if the magnetic disk is a data disk, step 1
Steps 11 and below are executed, but if it is a normal disk, steps 104 to 109 are executed.

If a data disk has been installed in advance and steps 111 and subsequent steps have been executed, the program diagram shown by the solid line S in FIG. 3 is stored in the RAM of the system controller 11, but steps 111 and subsequent steps have not yet been executed. In this case, for example, a program diagram indicated by the broken line in FIG. 3 is stored as basic imaging control data. Step 1
At step 04, the current contents of the RAM are displayed on the display device 51.

In step 105, the R of the system controller 11 is
It is determined whether the photographing control data stored in the OM and the photographing control data stored in the RAM are the same. If they are the same, proceed to step 10.
The process advances to step 6 to enter a photography standby state, and photography can be performed using the basic photography control data currently stored in the RAM.

On the other hand, in step 105, the ROM and RA
If it is determined that the photographing control data stored in M is different, it is determined in step 107 whether or not the photographing control data currently stored in the RAM is sufficient. This is done, for example, by the photographer operating the operation switch 12a based on the content displayed on the display device 51.

When photographing is to be performed using the photographing control data currently stored in the RAM, the process proceeds to step 106, but when photographing is not to be performed using the photographing control data currently stored in the RAM, step 108 is executed. That is, the data stored in the RAM is deleted, and the basic imaging control data in the ROM is read into the RAM in step 109.
At step 110 the contents of the RAM are displayed. Then, in step 106, the camera enters a photography standby state based on the basic side shadow control data newly stored in the RAM.

When the shutter of the camera is released in this state, an image is taken according to the diagram indicated by the broken line in FIG.

On the other hand, if it is determined in step 103 that a data disk is installed in the disk device, step 1
11 and below are executed. First, in step 111,
It is determined whether there is an instruction as to which track on the magnetic disk is to be read. This instruction is given by the photographer operating an operation switch. If there is an instruction to read a track, in step 112 the photographing control data stored in the instructed track is reproduced by the data reading circuit 46, and in step 113, the data that has been stored in the RAM of the system controller 11 is read out. The shooting control data that was previously saved will be deleted.

Next, in step 114, the imaging control data reproduced in step 112 is transferred to the system controller 11.
is read into the RAM.

In step 115, the contents of the photographing control data currently stored in the RAM are displayed on the display device 51, for example. This allows the photographer to recognize the photographing control data, and in step 120, the photographer decides whether or not the current photographing control data is acceptable, and operates the operation switch 12a.

If the current shooting control data is determined to be appropriate,
This completes this routine, but if it is determined that the current shooting control data is not appropriate, step 11 is performed again.
1 or less will be executed.

On the other hand, if it is determined in step 111 that there is no instruction as to which track of the magnetic disk to read,
Step 121 and subsequent steps are executed, and the photographing control data is reproduced for each track, and it is determined whether or not it is appropriate.

First, in step 121, a counter t is set to "I". Then, in step 122, the photographing control data stored in the t-th track is reproduced by the data reading circuit 46.

Steps 123, 124 and 125 are similar to steps 113, 114 and 115, respectively, that is, the imaging control data previously stored in the RAM of the system controller 11 is deleted, and the new imaging control data is stored in the RAM. and this RA
The contents of the photographing control data stored in M are displayed on the display device 51 or the like. In step 130, the photographer determines whether the current photographing control data is adequate, and if so, this routine ends.

If it is determined in step 130 that the current photographing control data is not appropriate, the counter t is incremented by "2" in step 131, and it is determined in step 132 whether the counter t has become "49" or more. If the counter t is less than "49", steps 122 to 130 are executed again. That is, the next photographing control data is reproduced, and it is determined whether this photographing control data is appropriate. The reason why the counter t is incremented by "2" in step 131 is that in this embodiment, the photographing control data is stored every two tracks. On the other hand, if it is determined in step 132 that the counter t is equal to or greater than "49", the process returns to step 121, the counter t is set to "1", and steps 122 to 130 are executed again.

After the photographing control data has been read into the RAM of the system controller 11 in this manner, the photographer can set a regular disk in the disk device and perform photographing based on the selected photographing control data. If the photographing control data is to be changed, the data disk may be set in the disk device again and the operations described above may be performed.

As described above, this embodiment is configured so that photography can be performed using the photography control data stored in the recording track of the magnetic disk, and such photography control data is stored on one data disk, for example. 25 types can be stored. Therefore, photography can be performed according to various photography control data different from the basic photography control data stored in the ROM of the system controller, and a variety of photography becomes possible. Furthermore, since such photographing control data is obtained from the magnetic disk, there is no need to provide a special operating mechanism in the camera body, and the configuration of the camera can be simplified.

Furthermore, conventionally, shooting control data was stored in the ROM of the system controller, but in this embodiment, the shooting control data is obtained from a magnetic disk, so it is necessary to incorporate a ROM in the camera to store the shooting control data. Alternatively, the area for photographing control data in the ROM can be reduced.

FIG. 6 shows a control circuit built into an electronic still camera according to another embodiment of the present invention. This embodiment differs from the embodiment shown in FIG. 1 in that it includes an audio processing circuit. That is, in this embodiment, when the magnetic disk is a normal disk,
It is possible to record audio as well as video, and if the magnetic disk is a data disk, it is possible to display the contents of the shooting control data with audio.

In this figure, the micro 1 is connected to an audio signal processing circuit 63 via a microphone amplifier 62, and the audio signal processing circuit 63 is connected to an A/D converter 65 via a switch 64. Therefore, the audio input from the micro 1 has high frequency components removed by the audio signal processing circuit 63, and
The signal is input to the D converter 65 and A/D converted. A/D converter 65, digital signal processing circuit 66, RAM 67, and D/A converter 68 are interconnected by data bus 69. The digital signal processing circuit 66 generates clock signals for the A/D converter 65, the RAM 67, and the D/A converter 68, and also performs writing and continuous processing for the RAM 67. Further, the digital signal processing circuit 66 is connected to the audio processing CPU 71, and the audio processing CPU 71 is connected to the system controller 11.

That is, the audio processing CPU 71 sends and receives data between the digital signal processing circuit 66 and the system controller 11.

The D/A converter 68 is connected to a compressed audio recording processing circuit 72, and the compressed audio recording processing circuit 72 is connected to the FM modulation circuit 41 via a switch 73.

The switch 73 connects the FM modulation circuit 41 to the video processing circuit 17.
Alternatively, it is configured to be selectively connected to the compressed audio recording processing circuit 72. That is, the switch 73 is connected to the video processing circuit 17 side when recording video, and is connected to the compressed audio recording processing circuit 72 side when recording audio. Therefore, when recording audio, the audio signal is input from the audio signal processing circuit 63 to the A/D converter 65 and converted into a digital signal, and then once transferred to the RAM 67, and then transferred to the D/A converter 65.
8, the signal is converted into an analog signal and input to the compressed audio recording processing circuit 72. Then, the audio signal is compressed to the time required for one rotation of the magnetic disk D (for example, 1/60 second), FM-modulated, and recorded on one recording track of the magnetic disk D.

Compressed audio reproduction processing circuit 74 is provided between FM demodulation circuit 42 and switch 64. The switch 64 is connected to the audio signal processing circuit 63 when recording audio, but is connected to the compressed audio reproduction processing circuit 74 when reproducing audio. Therefore, when playing back audio, the audio signal recorded on the magnetic disk D is FM demodulated, and then processed by the compressed audio playback processing circuit 74 in the opposite manner to that of the compressed audio recording processing circuit 72, and expanded into a predetermined amount of time. I am forced to do it. This audio signal passes through an A/D converter 65, a RAM 67, and a D/A converter 68, has high frequency components removed by an audio signal processing circuit 75, is amplified to a predetermined level, and is output to a speaker 76 or audio output. It is played back by a playback device connected to the terminal 77.

FIG. 7 is a flowchart showing the preparation operation for photographing in the electronic still camera having the control circuit shown in FIG. In this second embodiment, the contents of the photographing control data stored in the RAM of the system controller 11 at that time are output as audio from, for example, the speaker 76, so that the photographer can easily check the suitability of the photographing control data. It is structured so that it can be judged. Steps 116 to 118 and 126 to 128 are provided to confirm the photographing control data by voice. That is, steps 116-118 correspond to step 115 in the flowchart of FIG. 5, and steps 126-128 correspond to step 125 in the flowchart of FIG. Step 1
The operations of the other steps except steps 16 to 118 and 126 to 128 are the same as the operations of the corresponding steps in FIG. 5, and the explanation thereof will be omitted.

In step 116, audio waveform data corresponding to the imaging control data read into the RAM of the system controller 11 in step 114 is read. In this embodiment, photographing control data is stored in odd-numbered tracks of the magnetic disk, and audio waveform data is stored in even-numbered tracks. Each piece of audio waveform data is recorded in an inner track adjacent to the corresponding track of photographing control data. Therefore, in step 116, 1
The audio waveform data of the track obtained by adding the sum of . This audio waveform data is converted into A/
The signal is converted into D and stored in the RAM 67 of the audio processing circuit. Then, in step 118, the audio reproduction device connected to the speaker 76 or the audio output terminal 77 outputs an audio instruction indicating the contents of the photographing control data. The photographer can judge whether the photographing control data is appropriate based on this voice, and inputs the judgment result into the camera by operating a predetermined switch in step 120, as in the case of FIG.

The operations in steps 126 to 128 are performed in steps 11
It is the same as 6-118. That is, in step 124, audio waveform data corresponding to the photographing control data read into the RAM of the system controller 11 is read out, and this data is A/D converted and sent to the RA of the audio processing circuit.
The data is stored in the M67 and reproduced by the speaker 76 or other reproduction device.

As described above, according to this embodiment, the photographing control data stored in the RAM of the system controller 11 at that time is confirmed by voice. Therefore, the photographer can more accurately recognize the contents of the photographing control data, and it becomes easier to judge whether the photographing control data is appropriate.

In the embodiment shown in FIG. 7, the audio waveform data corresponding to the shooting control data is stored in the recording trunk adjacent to the recording track in which the shooting control data is stored, but the invention is not limited to this. , may be stored in other recording tracks. For example, the photographing control data may be stored in the 1st to 25th tracks of the magnetic disk, and the audio waveform data may be stored in the 26th to 50th tracks. In this case, information for associating the photographing control data with the audio waveform data may be stored, for example, in the control code of the cue track or the audio track.

FIG. 8 shows a third embodiment of a flowchart showing the preparation operation for photographing. In this embodiment, an example that well expresses the characteristics of the shooting control data stored in the RAM of the system controller 11 at that time is the video output terminal 1.
The image is displayed by a playback device (not shown) connected to 8. This allows the photographer to easily determine whether the photographing control data is appropriate. Steps 119 and 12 are performed to confirm the shooting control data according to the example of such a video.
9 are provided and these steps 119 and 1
29 correspond to steps 115 and 125, respectively, in the flowchart of FIG.

The operations of the other steps except steps 119 and 129 are the same as the operations of the corresponding steps in FIG.
The explanation will be omitted.

In step 119, video data corresponding to the photographing control data read into the RAM of the system controller 11 in step 114 is read. In other words, this video data shows a typical example of a video shot based on the shooting control data, and this video is output to the playback device and displayed on the screen as described above. Similar to the seventh embodiment, shooting control data is stored in odd-numbered tracks of the magnetic disk, video data is stored in even-numbered tracks, and each video data is stored in the corresponding shooting control data. Recorded on the inner track adjacent to the track. Therefore, in step 119, the video data of the track obtained by adding 1 to the track of the photographing control data is reproduced. The photographer can judge whether the photographing control data is appropriate based on this image, and inputs the judgment result into the camera by operating a predetermined switch in step 120.

The operation in step 129 is similar to step 119 and all (
The same is true.

According to this embodiment, an example of photographing based on the photographing control data stored in the RAM of the system controller 11 at that time is confirmed by the video. Therefore, the photographer can more accurately recognize the contents of the photographing control data, and can easily judge the photographing control data.

Note that the video data corresponding to the shooting control data does not need to be stored in a recording track adjacent to the recording track in which this shooting control data is stored, and may be stored in another recording track. For example, the photographing control data may be stored in the 1st to 25th tracks of the magnetic disk, and the video data may be stored in the 26th to 50th tracks. In this case, information for associating the photographing control data with the video data may be stored in, for example, a cue track.

FIG. 9 shows a fourth embodiment of a flowchart showing preparation operations for photographing. This embodiment, like the embodiment shown in FIG. 8, is configured so that the photographer can select photographing control data using an image.

In step 201, a magnetic disk (data disk)
Operation switch 12b or 12 for track feed of
It is determined whether c is in the on state. If the track feed switch is not on, step 202 is skipped and step 203 is executed; however, if the track feed switch is on, step 202 is skipped and step 203 is executed.
is executed and only one recording track is sent. In step 203, it is determined whether or not the playback button provided on the camera is in the on state. If it is not in the on state, this routine ends, but if it is in the on state, step 204
The following is executed to select the photographing control data.

In step 204, the video and reference data stored in the currently set recording track are read. This video shows a typical example of a video shot according to the corresponding shooting control data, and is recorded using the same method as a normal disc.

That is, the video signal is divided into a luminance signal and a color difference signal, and is FM modulated and recorded.

In addition, data such as dates are usually multi-recorded in a DPSK-modulated track on a track where a video is recorded, but in the data disc of this embodiment, data corresponding to the video is stored as reference data in the DPSK-modulated user's area. Track numbers in which photographing control data is stored are DPSK-modulated and multiplex recorded.

In step 205, it is determined from the DPSK modulation data whether this magnetic disk is a data disk or a normal disk. In the case of a regular disc, in step 206 normal playback is performed, that is, the video recorded on the regular disc is played back on the screen of the playback device. On the other hand, if it is determined in step 205 that a data disk is currently installed in the disk device, in step 207, a message that photography is possible based on the photography control data is displayed on the display device 51, etc. 2
The video read in step 04 is displayed on the screen of the playback device.

By viewing this video, the photographer can judge whether the shooting control data is appropriate or not, and step 208
This photographing control data is selected by switching the operation switch at .

That is, if the photographing control data is appropriate, the photographing control data is read from the data disk into the RAM of the system controller 11 in step 209, and this routine ends. As a result, from then on, photography will be performed based on this photography control data.

On the other hand, if it is determined in step 208 that the photographing control data is not appropriate, step 209 is skipped and the photographing control data stored in the RAM of the system controller 11 is not changed. In this case, the photographer operates the track advance switch on the data disk (steps 201 and 202), turns on the playback button (step 203), and checks the next video (steps 207 and 208). By repeating such operations, appropriate photographing control data is selected.

This embodiment also provides the same effects as the embodiment shown in FIG.

In each of the above embodiments, a program diagram consisting of an EV value, an F value, and a shutter value was given as an example of the photographing control data stored in the recording track of the magnetic disk.
The program is not limited to this, and may be a zooming operation program, for example. That is, in this case, the system controller 11 controls the zoom mechanism according to a program obtained from the magnetic disk. Further, the control data obtained from the magnetic disk does not have to be related to photographing, and may be data for controlling other than photographing.

As described above, according to the present invention, even if an electronic still camera has only a simple operation mechanism, it is possible to perform various controls with simple operations, and it is also possible to accurately recognize the contents of the control. You can get the effect that you can.
