Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a still picture video reproducing apparatus, and more particularly, to a reproducing apparatus capable of arbitrarily changing a reproducing procedure in still picture video frame-by-frame reproduction.

<Prior Art> In recent years, instead of a conventional silver halide film camera, an optical image signal from a subject is converted into an electric image signal by an image sensor, and the electric image signal (still image signal) is converted to a conventional film. A still video camera configured to record on a corresponding recording medium such as a magnetic disk has been put to practical use, and the electric image signal recorded on the recording medium is reproduced and viewed on a monitor, or used by hard-copying with a printer. (See Japanese Patent Application Laid-Open No. 59-188352, etc.).

<Problems to be Solved by the Invention> By the way, a plurality of still image images recorded on a recording medium by the still video camera as described above can be reproduced by a reproducing device integrally provided in the still video camera or an independent reproducing device. In the case of reproduction on a monitor, generally, frame-by-frame reproduction is performed in the order of addresses of a recording medium (interval reproduction). Here, the frame feed time in the frame feed reproduction can be set arbitrarily in the past. However, when the user wants to reproduce the still image video in an arbitrary order from the recording medium, the user has to manually set the time each time. Select a still image according to the desired playback order, or
It becomes necessary to prepare a recording medium in which still images are exchanged in a desired reproduction order, and if a user attempts to reproduce in a desired reproduction order, complicated operations and operations are required.

In consideration of this, it was considered that the user can set the playback procedure in advance to specify the order of the video to be played so that the playback can be repeatedly performed in an arbitrary playback order. When the method of designating each image and video is adopted, for example, 10 tracks from 1 track to 10 tracks are reproduced in order, and then when the user wants to jump to 15 tracks next, it starts from 1 according to the track order.
It is necessary to designate all 10 tracks up to 10 as 1, 2, 3,..., 10, which causes a problem that it takes time to set the reproduction procedure.

Also, for example, when shooting a golf swing or baseball batting form with a still video camera and reproducing the same, the frame is continuously played back until the moment of impact, and the image of the moment of impact is captured. There is a demand to pause and then feed the rest of the still image video, and to repeat the playback pattern many times to use it for form analysis, etc. If you want to temporarily stop playback during frame-feed playback, it is necessary to pause it by operating the buttons on the remote control or the main unit.If the operation timing of the pause button is shifted from the moment of impact, The operation becomes complicated, for example, it is necessary to search for a video that captures the moment of impact when the button is operated. There was a problem that is.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and enables a user to automatically reproduce a still image from a recording medium in any order, and to perform intermediate playback during interval playback (interval playback). The playback procedure for pausing at a constant image can be set in advance to improve the usability in sports form analysis and the like, while the number of consecutive addresses in the frame-by-frame playback in which the addresses of the recording medium are designated and played in the playback order is improved. It is an object of the present invention to provide a still image reproducing apparatus capable of easily setting a reproduction order of still image.

<Means for Solving the Problems> Therefore, in the present invention, as shown in FIG. 1, a recording medium for recording a plurality of still images as electric signals, and a plurality of still images from the recording medium are framed. A reproducing procedure storing means for rewritably storing a procedure for feeding and reproducing; a reproducing means for progressively reproducing a still image video signal from a recording medium in accordance with the reproducing procedure stored in the reproducing procedure storing means; A procedure rewriting means for rewriting and setting a reproduction procedure stored in the storage means, wherein the procedure rewriting means performs a predetermined still image video among a plurality of still image videos to be framed and reproduced. A playback procedure in which continuous playback is performed by temporarily stopping frame-feed playback, and the pause is released based on a signal input from the outside to restart frame-feed playback. It was to be configured to include a continuous reproduction setting means for setting the serial reproduction procedure storage means.

Here, the procedure rewriting means is configured separately from a main body integrally provided with the recording medium, the reproduction procedure storage means, and the reproduction means, and the reproduction procedure is set by remotely controlling the reproduction procedure storage means. Can be configured.

Further, as described above, the main body integrally provided with the recording medium, the reproduction procedure storage means, and the reproduction means, which is separate from the procedure rewriting means, converts the optical image signal into an electric image signal to obtain a still image. A still image recording apparatus for recording an image on a recording medium may be integrally provided.

Further, a reproduction remote control means for operating the reproduction means by remote control may be provided integrally with the procedure rewriting means.

<Operation> According to the still picture reproducing apparatus having such a configuration, the reproduction procedure rewritten and set by the reproduction procedure rewriting means is:
It is rewritably stored in the reproduction procedure storage means, and the reproduction means frame-by-frame reproduces a plurality of still images from the recording medium in accordance with the stored reproduction procedure.

Here, the continuous playback setting means performs continuous playback by temporarily stopping frame-based playback at a predetermined still image of the plurality of still images to be played back frame-by-frame, and sets the pause to an externally input signal. , A playback procedure for releasing the frame-by-frame playback is set, and the frame-by-frame playback is interrupted during the frame-by-frame playback, and the set still image video is continuously played back. Thus, during frame-by-frame playback from a recording medium on which a still image of a golf swing or the like is continuously shot, for example, the frame-by-frame playback is paused at a still image captured at the moment of a ball impact. If the playback procedure is set in advance so that the pause is released by an external signal, the playback unit performs frame-by-frame playback until the moment of impact, but captures the moment of impact. Since the still image is played continuously until the pause is released by an external signal, the frame feed can be paused at the desired position, such as at the moment of impact, without the need for user operation. Further, the paused video can be continuously reproduced without any time limitation.

Further, the procedure rewriting means may be configured separately from the recording medium, the reproduction procedure storage means, and the main body integrally provided with the reproduction means, and the reproduction procedure storage means may be remotely controlled to set the reproduction procedure. With this configuration, the setting of the playback procedure can be easily performed by a so-called remote control operation.

In addition, the recording medium, the reproduction procedure storage means, and the reproduction means are provided with a so-called reproduction function integrally provided in a still image recording apparatus for converting an optical image signal into an electric image signal and recording a still image on a recording medium. With this camera, the reproduction procedure stored in the camera by the procedure rewriting means can be set by remote control operation.

Further, by providing a reproduction remote control means for operating the reproduction means by remote control integrally with the procedure rewriting means, the reproduction procedure can be set and the reproduction can be started by the remote control.

To input a remote control signal to the remote controller.

FIG. 7 shows an operation panel of the remote control unit. First, functions of various switches shown here will be described.

The power ON / OFF switch 71 is a switch for controlling the power of the still video camera main body. When the switch 71 is pressed in the OFF state (ON state) of the main body, the main body is turned ON (OFF state).

The eject switch 72 is a switch for ejecting the floppy disk loaded in the still video camera, and the loading of the floppy disk is performed manually.

The jog shuttle dial 73 is used to select a track number or to set an interval time in a program playback described later, and the shuttle ring 73a is used to automatically increase and decrease the track number in four steps at a high speed. In the figure, turning the watch clockwise (counterclockwise) automatically increases (down) the track number, and turning it more clockwise (counterclockwise) increases the up (down) speed. It is. The jog dial 73b is for sequentially increasing or decreasing the track number in accordance with the rotational operation speed, and has a clockwise direction as an up direction and a counterclockwise direction as a down direction similarly to the shuttle ring 73a.

The display ON / OFF switch 74 is used to switch ON / OFF the display of the track number being played back. In the ON state, the playback track number of the still video camera which is switched to the playback mode is played back by the character generator circuit 38. The image is displayed on a monitor connected to the still video camera at a predetermined position in addition to the screen.

The one-track erasure switch 75 and the all-track erasure switch 76 are switches for selecting one-track erasure or all-track erasure when the still video camera is in the erasure mode. Is turned on, "ERASE THIS TRACK?" Or "ERAS" appears on the monitor connected to the still video camera.
E ALL TRACK? Is displayed, and when the execution switch 77 is pressed in this state, erasing one track or erasing all tracks is executed. The erasing operation is canceled by the stop switch 78, and the one-track erasing switch is canceled.
Turn ON the 75 or ALL TRACK ERASE switch 76, and when the erase message is displayed on the monitor,
By pressing 78, the operation of the erase switches 75 and 76 is canceled and the erase message disappears.

The execution switch 77 instructs execution in the erasing mode as described above, and also controls the playback track number, interval time, and the like in program playback (frame-feed playback according to a playback procedure arbitrarily set by the user) described later. Used for setting (ENTER).

The memory clear switch 88 is a switch for clearing the memory of each set value of the program reproduction. The memory clear switch 88 is a user memory (for example, a rewritable backup) provided as a reproduction procedure storage means provided in the main CPU 20 of the still video camera. Clears the playback procedure of frame-by-frame playback arbitrarily set by the user for the attached RAM) and returns to the initial state. If program reproduction is selected when each set value of the program reproduction is cleared by the memory clear switch 88, the track recorded on the video according to the preset frame-feed reproduction procedure (reference reproduction procedure) is set. Are sequentially played back at an interval time of 2 seconds (default playback).

The continuous playback switch 79, which will be described later in detail, is a switch for giving an instruction to sequentially perform playback between two tracks when setting a playback track number for program playback.

The program playback stop switch 80 "P-stop *"
This is used when setting a program to pause at a predetermined image at the time of frame-by-frame playback started by a program playback switch described later, which will be described later in detail. Equivalent to.

Further, the program setting / ending switch 81 is a switch used when the operation for setting the reproduction track number and the interval time in the program reproduction is started, and when the setting is ended and confirmed. If the program reproduction switch is turned on during the setting of the reproduction procedure of the program reproduction, the program reproduction is started if the set value is valid.

The reproduction switch 82 is a switch for starting reproduction, and also functions as a release switch for a pause state. However, when turned on during program playback, the program exits from program playback and enters the normal playback mode.

The stop switch 83 is a switch for stopping the normal reproduction and the program reproduction. When the stop switch 83 is turned on, the screen is in a muted state.

The program reproduction switch 85 is a switch for performing program reproduction. When this switch is turned on, frame-forward reproduction is performed according to a reproduction procedure arbitrarily set by the user. However, when each data for reproduction is not set or cleared, reproduction is performed along a track number with an interval time of 2 seconds stored as a default value (reference reproduction procedure).

Therefore, in this embodiment, the function as the playback remote control means is provided in the remote control unit having the configuration as shown in FIG.

The release switch 86 is a switch for releasing in a shooting mode (continuous shooting / strobe) set on the still video camera side.
Shooting is performed while it is ON. This release button 86
By using a remote control, a shooting operation can be performed at a position away from the still video camera by a remote controller.

The 2 sec release switch 87 is used to release a single shot 2 seconds after the switch is turned on, and a still video camera can shoot 2 seconds after the remote control is operated.

Next, a description will be given of the setting of the reproduction procedure (rewriting of the reproduction procedure) of the program reproduction using the remote control unit having the operation switches of the above configuration and functioning as the procedure rewriting means. Note that the program reproduction is a method in which a still picture image stored on a proppy disk is reproduced step by step according to a reproduction procedure arbitrarily set and stored by a user in advance.

First, when the program setting / end switch 81 is turned on,
The still video camera receiving this signal displays the message "INTERVAL TIME?" On the connected monitor TV and prompts the user to set the playback interval time. The user operates the jog shuttle dial 73. As a result, a desired interval time is searched for and displayed from a plurality of types of interval times (frame feed interval times) sequentially displayed on the monitor television. Then, when the desired interval time is displayed, the execution switch
Pressing 77 confirms the displayed interval time. It is desirable that the determined interval time is displayed in a determined value area provided on the lower side of the monitor television or the like.

As the interval time selected by the user as described above, for example, 0.1 0.2 0.4 1 2 3 5 7 10 20 30 40 50
(Second) 1 2 3 5 7 10 20 30 40 50 60 (Minute), and operate the jog shuttle dial 73 clockwise to display from 0.1 second on the chronological monitor, the desired interval time , The display is returned by operating the jog shuttle dial 73 in the counterclockwise direction to display a desired interval time.

When the setting of the interval time is completed as described above and confirmed with the execution switch 77, a message of “START TRACK NO?” Is displayed on the monitor television,
You will be prompted to set the track number to be played first,
The user operates the up / down of the track number with the jog shuttle dial 73 while watching the track number displayed on the monitor TV, and displays the track number on which the video to be played first is recorded on the monitor, By pressing the execution switch 77, the track number to be reproduced first is determined.

When a desired track number is searched for by displaying the track number on the monitor as described above, a playback screen recorded on the track may be displayed in the background. Further, the track numbers determined by pressing the execution switch 77 may be sequentially displayed on a lower portion of the monitor television or the like.

When the track number you want to play first is determined,
Next, the message "NEXT TRACKNO?" Appears on the monitor and prompts you to set the track number you want to play next. Use the jog shuttle dial 73 to set the track number in the same way as when setting the first playback track. Select and confirm with the execution switch 77.

Here, in addition to directly specifying a track number and determining a reproduction procedure as described above, a special key can be selected by a continuous reproduction switch 79 and a program reproduction stop switch 80.

When the program playback stop switch "P-stop *" 80 is pressed when the track numbers in the playback order are set as described above, after the previously designated track number, for example, "36"
The "*" mark is displayed, such as "* 910".
This “*” mark indicates that when frame-by-frame playback is performed up to the previously set track number, frame-by-frame playback is paused and playback of the still image recorded on the track number is continued. When the program playback switch 85 is pressed while the unit is in the continuous playback mode after the frame is played back to the track number marked with “*” mark, the unit exits the continuous playback mode and starts again from the next track number. Frame-by-frame playback can be performed. Therefore, for example, as described above, “36 *
When the setting of “9 10” is made, if the video is advanced to track 6 after playback of track 3, the video of track 6 is played continuously, and if the continuous playback is canceled, the video is played from track 6 to track 9.10. It is played back.

The above configuration corresponds to the continuous reproduction setting unit in the present embodiment.

When the continuous playback switch 79 “Continuous” is pressed when setting the track number in the playback order as described above, the arrow mark “” is displayed next to the previously specified track number, and the track number is set after the arrow mark “”. Then, the setting is made to reproduce each track in order from the track number before the arrow mark "" to the track number after. Therefore, if "110" is set, playback starts from one track and starts at 1,2,3, ..., 1
Each of the tracks from 0 to 1 to 10 is reproduced. If the track number after the arrow mark "" is smaller than the track number before the arrow mark "", the track numbers are sequentially reproduced in the backward direction. Therefore, when there are a plurality of tracks to be reproduced in the order of the track numbers, only the first track number and the last track number need to be designated, and the setting operation is simplified.

If the reproduction procedure of the program reproduction is set to, for example, "110 * 202" using the special keys as described above, and the still video camera is set to the reproduction mode and the program reproduction is started by pressing the program reproduction switch 85,
First, reproduction is started from the first track of the floppy disk, and after an interval time set by the user elapses, the program shifts to the next two tracks, and is sequentially advanced.
Play up to 10 tracks. However, if there is a track on which no video is recorded from the 1st track to the 10th track, that track is skipped during playback and the next track is played back. It can be invalidated.

In this way, when the frame is fed up to 10 tracks, the frame feeding is interrupted, and the still image recorded on the 10 tracks is continuously reproduced. Here, if the user does not perform any operation, the reproduction of the 10 tracks is continued, but when the user presses the program reproduction switch 85 or the pause switch 84, the reproduction of the track is specified after the 10 tracks. The playback shifts to 11 tracks, and since “1020” is set, when the program playback switch 85 is pressed to release the pause, the tracks from track 10 to track 20 are successively played back.

When the frame-forward playback of up to 20 tracks is completed, this time is set to “202”, so that 20 tracks will be replaced by 19,1
The reproduction is repeated in the reverse direction to 8, returning to the second track, and the reproduction from the first track which is the start track is repeated again. In the above-described program reproduction, the reproduction is started from one track.
When the playback pattern ends with 20 tracks,
Playback is repeated from track 20 to track 1. Then, when it is desired to stop the repeated program reproduction, the stop switch 83 and the reproduction switch 82 may be pressed.

In this way, if the frame feed is automatically paused at a predetermined track, for example, the shooting content is continuous shooting of a golf swing, etc. If you want to carefully observe the video that captures the moment, you can add a “*” mark to the track number where the video at the moment of the ball impact is recorded and set the playback procedure in advance. The reproduction pattern to be stopped can be repeatedly performed, and the usability when the still video camera is used for analysis of a sports form and the like is improved.

For example, when “110 10 1020” is set, frame-by-frame playback is performed at the set interval time from track 1 to track 9;
After the transition to the reproduction of the 10 tracks, since the 10 tracks is designated by 3 consecutive, only 10 tracks can be played three times set interval time (or 8 times = 2 ³ times) longer.

In this way, for a track that is desired to be played back longer than other tracks, the playback time can be lengthened by setting a plurality of track numbers consecutively, and in this case, the Even if is not operated, after a certain reproduction time has elapsed, it is possible to skip to the next track.

When the still video camera is set to the playback mode and the program playback switch 85 of the remote control unit is pressed to perform the program playback, when the jog shuttle dial 73 is operated with the pause switch 84 turned on,
The playback track selection by the jog shuttle dial 73 becomes effective, and the track can be advanced by the jog shuttle dial 73 prior to the program playback.

Further, in the above embodiment, only one type of program reproduction procedure is stored and set. However, a plurality of types of reproduction procedures can be stored and a pattern to be reproduced during program reproduction is selected. You may do it.

Further, when the program playback is started by pressing the program playback switch 85, if the interval time and the playback track order are not set, the frame playback is performed as a default playback according to the track order of the 2-second interval time, When only the interval time is set, the interval time is treated effectively and the floppy disk is sequentially played back in the track order.

Further, when the previously set contents remain without being cleared at the time of setting the reproduction procedure of the program reproduction, the new set contents are overwritten and updated, and for the set contents which do not need to be updated, the execution switch 77 is used. By pressing, it can be followed as it is. When the previous settings remain, move the cursor to the content you want to change using the jog shuttle dial 73, and set a new playback procedure by setting only the changed part. Can also.

Here, the procedure setting of the program reproduction outlined above will be described in detail with reference to the flowcharts of FIGS.

In the flowchart of FIG.
In the figure, it is determined whether or not the program setting is selected by the program setting / end switch 81. When the program setting is selected by the switch 81, the interval time is set in step 2. Is performed.

The above-mentioned interval time setting is shown in the flowchart of FIG. 9. First, in step 11, a message "INTERVAL TIME?"
In step 12, the storage content of the area for storing the interval time is set to B.

Then, in step 13, it is determined whether or not the interval time has been set by confirming the contents set in B. If not, the default interval time (for example, 2 seconds) is set to B in step 14. Set.

In this way, when the interval time before updating is set to B, in step 15, the “INTERV
AL TIME? "And the interval time before the update are displayed on the monitor TV.

Here, if the interval time displayed on the monitor television is good, the execution switch 77 is pressed. Then
The process jumps from step 16 to step 19 for determining ON / OFF of the execution switch 77 to determine the display content of the monitor television as an interval time and store it in the memory. In the next step 20, the determined interval time is monitored. Display on TV.

On the other hand, if the user wants to change the interval time displayed in step 15, the user operates the jog shuttle dial 73 to sequentially display a plurality of preset interval times on the monitor (step 17), and sets the desired interval time. Is displayed, if the execution switch 77 is pressed, the interval time displayed on the monitor at that time is determined (step 18 → step 1).
9).

Returning to the flowchart of FIG.
When the setting of the interval time is completed as described above, when the program setting / end switch 81 is pressed,
Since the program setting is completed, the process proceeds to step 4 to perform default setting of the reproduction track.

In step 4, as the track order at the time of program reproduction, "1" is set so that the last track (for example, 50) is reproduced sequentially from one track of the floppy disk.
Set "50".

On the other hand, after the interval time is determined, program setting /
If the end switch 81 is not pressed, the order of the reproduction tracks can be programmed (step 5), and the program setting of the order of the reproduction tracks is performed as shown in the flowchart of FIG.

First, in step 31, A displays “START TRACK NO?”
In the next step 32, the content of the memory area storing the start track number is set to B.

Then, it is determined whether or not a start track has been set based on the content set in B (step 33). If no start track has been set, the process proceeds to step 34, where the playback track order is first determined according to the track number. The default playback order, that is, one track is set.

Then, in step 35, the "START T
RACK NO? And the start track number determined by the previous program setting or default setting is displayed on the television monitor.

In the next step 36, all the track numbers to be reproduced following the start track according to the current program settings are displayed as the pre-update date on the start track. In the case of the default setting, "150" is displayed on the monitor.

Here, when the execution switch 77 is pressed (step 3
7), the number of the start track is determined as the display number on the monitor, and this track number is stored in the memory in step 38, and is set as the determined value in the next step 39
To display.

On the other hand, when it is desired to update the start track number, the desired start track is displayed on the monitor using the jog shuttle dial 73 in step 40 and the execution switch 77 is pressed (step 41), whereby the start track can be arbitrarily updated and set.

When the start / stop switch 81 is pressed after the start track is determined (step 42), the program setting is terminated at that point, and only the start track is updated and the program setting is completed.

On the other hand, when it is desired to update the second and subsequent reproduction tracks, the update setting of the second and subsequent reproduction tracks can be performed in the next step 43 and thereafter unless the program setting / end switch 81 is pressed.

In step 43, the message "NEXT TRACKNO?" Is set in A, and in the next step 44, N (initial value =
2) Set the number before update set as the second reproduction track to B.

Then, in step 45, the message "NEXT TRACKNO?" And the track number before the update are displayed on the monitor television.

Here, if the track number displayed on the monitor can be used, the execution switch 77 is pressed, and
Then, the track number is stored in the memory as the N-th reproduction track number, and the track number of the determined result can be displayed in the next step 50.

On the other hand, when it is desired to update the track number, the desired track number is displayed on the monitor by operating the jog shuttle dial 73 and then the execution switch 77 is pressed, whereby the Nth reproduction track number can be updated (step 47). , 48).

When it is not necessary to update the remaining reproduction tracks at the stage when the update of the track numbers up to the N-th is completed in this way, the program setting mode is immediately ended by pressing the program setting / end switch 81. (Step 51).

Then, when it is desired to continuously update the data after the next reproduction track, N is incremented by 1 in step 53, and the process returns to step 44 again to perform the same setting.

As a result of sequentially updating the reproduction tracks as described above, if the last reproduction track is updated, the program setting is terminated in step 54 until the program setting / end switch 81 is pressed.

Next, a description will be given of the program reproduction according to the reproduction procedure updated and set as described above with reference to the flowcharts of FIGS.

This program playback is started by pressing the switch 85 for program playback of the remote control unit with the still video camera in the playback mode.

When the program playback switch 85 is pressed, first, in step 61, the contents of the memory storing the interval time for program playback (memory built in the main CPU 20) are read out. In the next step 62, the interval time is read out. It is determined whether or not it has been set.

If the interval time has not been set, 2 seconds which is the default time corresponding to the reference reproduction procedure is set as the interval time which is a reproduction procedure parameter (step 63), and is set to 1 regardless of the program content in the reproduction track order. A default reproduction for sequentially reproducing the tracks from the track to the last track is performed (step 66).

Since the default reproduction is one pattern of the program reproduction, release control and pause control based on various switch devices during the program reproduction are similarly performed.

On the other hand, when it is determined in step 62 that the interval time has been set, the process proceeds to step 64, where the address where the start track number is stored is set to A, and the contents of the address set in A, that is, the start Set the track number to N.

Then, in the next step 65, it is determined whether or not a start track has been set based on the content set in N. If the start track, which is a playback procedure parameter, has not been set, the start track is also determined. Then, the process proceeds to step 66 in which the default reproduction (reference procedure reproduction) to be performed is performed.

If the start track has been set, N tracks are reproduced in step 67, and the current reproduction track number is set to N 'in order to determine whether or not the next reproduction track is the same track.

Then, in the next step 68, an interval process based on the set interval time is executed. The contents of the interval processing are shown in the flowchart of FIG.

In the flowchart of FIG. 12, first, step 81
Then, the counting of the interval time is started.

In step 82, it is determined whether or not the reproduction switch 82 has been pressed during the interval. If the reproduction switch 82 has been pressed, the program reproduction is interrupted and the mode is shifted to the normal reproduction mode (step 83). Therefore, if it is desired to view the video in a sequence other than the preset reproduction order during the program reproduction, pressing the reproduction switch 82 allows the jog shuttle dial 73 to reproduce the video of the desired track. .

In step 83, it is determined whether or not the stop switch 83 is pressed during the interval. When the stop switch 83 is pressed, the process proceeds to step 85, the screen is muted, and the playback switch 82 or the program playback switch It waits until 85 is pressed and the playback trigger is applied again.

Further, in step 86, it is determined whether or not the pause switch 84 has been pressed during the interval.
When the button 84 is pressed, a temporary stop control described later is executed in a step 87.

Then, in a step 88, it is determined whether or not the interval time T has elapsed. If the interval time T has not elapsed, the flow returns to the step 82 again to continue the current reproduction state.

Note that the interval processing shown in the flowchart of FIG. 12 is similarly performed in the interval time control in the default reproduction in the step 66.

Here, the suspension control in step 87 will be described with reference to the flowchart of FIG.
At 91, it is determined whether or not the jog chart dial 73 has been operated to generate a signal.

When the jog shuttle dial 73 is operated with the pause switch 84 pressed during program playback (including default playback; the same applies hereinafter), the program playback mode is exited at that point and the normal playback mode is exited. (Step 92), and the track selected by the jog shuttle dial 73 can be reproduced.

Therefore, during program playback, for example, if you want to check the video that has already been framed, press the pause switch 84 and then use the jog shuttle dial 73 to return the track number. The jog shuttle dial 73 can be used to search for a track to be viewed as a base point.

On the other hand, even when the jog shuttle dial 73 is not operated, if the pause switch 84 is pressed and then the play switch 82 is pressed during program playback (step 93), the mode shifts to the normal play mode, and the jog shuttle dial 73 is used. The playback track can be selected.

When the pause switch 84 is pressed and then the stop switch 83 is pressed during program playback (step 94), the screen is muted, and the video is not played back until the playback switch 82 or the program playback switch 85 is pressed (step 94). Step 95).

Further, when the program playback switch 85 is pressed (step
96), it is determined in step 97 whether or not the program is being reproduced. This is because the routine shown in FIG. 13 is executed when the pause switch 84 is pressed regardless of whether or not the program is being reproduced.

If it is determined in step 97 that the program is being reproduced, the routine is terminated to exit the paused state and restart the program reproduction. Execute from the initial state.

If it is determined in step 99 that the temporary stop switch 84 has been pressed again, this routine is terminated as it is, and the temporary stop state is released.

Therefore, when the pause switch 84 is pressed during program playback and the program is paused, the program playback switch
If you press 85 or press the pause switch 84 again,
The pause is released and the program playback is resumed. Also, when continuous playback is performed by the “*” mark in the program settings, the same operation is performed as if the pause switch 84 was pressed, so if the program play switch 85 or the pause switch 84 is pressed, the next setting will be performed. Frame playback can be executed.

Here, returning to the flowchart of FIG. 11, when the above-described interval processing is completed and the program reproduction is to be continued, the steps from step 68 to step 68 are performed.
Proceed to 69 to set a memory address where a track number to be reproduced next is stored.

Then, in the next step 70, the content set in the updated memory address is read, and in a step 71, it is determined whether or not the track number to be reproduced next has been read.

When the track number is read,
Proceeding at 72, when the same track number as the previously read track number is read again, the interval time of that track is set and controlled according to the continuously set number of times, and a different track number from the last time is read. When this is done, interval control is performed based on the set value of the interval time.

On the other hand, if the address at which the playback track is to be stored is blank (step 73), the process returns to the address at which the start track number is stored (step 74), and returns to step 67. Then, the reproduction from the start track to the space setting is repeated.

If “continuous” is set at the address where the playback track should be stored (step
75), controls to sequentially play back each track between the track number read last time and the track number set after "Continuous" setting along the set interval time (Step 76).

Further, when “pause *” is set at the address where the playback track should be stored (step
77), the pause control shown in the flowchart of FIG. 13 is executed (step 78), and the state is the same as when the pause switch 84 is pressed.

Therefore, if there is a video that you want to pause in advance,
Even if you do not operate the pause switch 84 during playback, if you set “Pause *” after the corresponding track in the program settings, you can automatically pause, and the pause will be assured Done.

In this embodiment, the still video camera has both functions of recording and playback. However, a configuration may be adopted in which the playback is performed by an independent device as a playback device. In this case, FIG. The remote control unit shown becomes a remote control unit for the playback device, and the release switches 72 and 74 become unnecessary.

Further, instead of using the remote control unit as shown in FIG. 7, a configuration may be provided in which the main body is provided with various switches for program setting, a program reproduction start switch, and the like.

Further, the remote control unit may be configured to send a signal to the main body by wire.

Further, the recording medium is not limited to a floppy disk, but may use a semiconductor memory or the like.

<Effects of the Invention> As described above, according to the present invention, a plurality of still images recorded on a recording medium can be frame-by-frame reproduced in an order according to a user's desire, and frame-by-frame reproduction can be performed. If there is a video that you want to pause and play continuously in the middle of the course, you can set a pause corresponding to that video in advance. The moment can be automatically paused and viewed, and the paused video can be played continuously without any time restrictions.
