KR0164557B1 - Reproducing method of still picture in searching - Google Patents

Abstract

Performing a search operation of the VCR generates noise bars, making it difficult to reliably recognize the search screen.

Since the playback operation must be performed during the search operation, the inconvenience of the switch operation during the search operation is accompanied.

Therefore, when the search operation is performed, the present invention counts the execution time of the search operation and checks whether a predetermined time has elapsed.

When the search operation is performed for a certain time, the still image is played and the still image playback time is counted to check whether the set time has elapsed.

When the still picture is reproduced for a predetermined time, the search operation is performed and the above operation is repeated, thereby eliminating the inconvenience of the switch operation for checking the screen during the search operation.

The present invention relates to a search method of a VCR that records and reproduces a video signal.

The present invention relates to a still picture reproducing method during a search operation such that a still picture is reproduced at a predetermined time during a search operation.

The VCR has a search function for quickly searching for a desired scene among scenes recorded on a tape. The search function described above is performed by a forward search or reverse picture search switch input during a playback operation.

When the above search function is executed, the tape can be reproduced at a constant speed (fixed by design when producing a set) so that a user can find a desired scene.

When performing the search function, the search screen appeared noise bars, and it was difficult to check the desired screen in the search screen state. Therefore, the search screen was switched to the playback mode during the search operation to check the current playback screen state.

In other words, to search for the desired scene by pressing the search switch, the user must switch to the playback mode every halfway to find the desired scene. If the scene is not the desired scene, the search screen must be repeated by pressing the search key again. It was inconvenient to find the desired scene.

As described above, in the conventional VCR, it is necessary to check whether a desired scene is displayed by reproducing every intermediate operation during the search operation. Therefore, inconvenient inconvenience is caused in the present invention. By playing it, you can find the screen you want more conveniently.

As described above, an object of the present invention is to provide a method for reproducing a still image whenever a predetermined time elapses during a search operation, and counting the search operation execution time when the search operation is performed to check whether a predetermined time has elapsed.

When the search operation is performed for a certain time, the still image is played and the still image playback time is counted to check whether the set time has elapsed.

When the still picture is reproduced for a predetermined time, the search operation is performed and the above operation is repeated.

This invention will be described in detail based on the accompanying drawings.

1 is a VCR configuration diagram to which the present invention is applied. In block 70, the servo data is recognized while the signal reproduction recording section 50 is controlled.

Here, the signal reproduction recording unit 50 records or reproduces an image signal under the control of the scissor microcomputer 40, and the reproduced image signal is displayed through the TV 60.

The servo block 70 receives data of the sheath cone microcomputer 40 to control the driving of the drum motor 80 and the capstan motor 90.

For example, when the regeneration switch of the remote controller 10 or the function switch unit 20 is pressed, the scissor microcomputer 40 recognizes this and applies a loading motor driving signal to load the tape to the servo block 70 while the signal is received. A surge that rotates the drum motor 80 and the capstan motor 90 upon applying the regeneration control voltage to the reproducing recording unit 50 to switch the internal signal flow to match the reproducing operation and recognizes through the sensor 30 that the loading operation is completed. The beam data is applied to the servo block 70 and the drum motor 80 is rotated while the tape is transferred to the capstan motor 90 to pick up the signal by the rotating head, and then the signal reproduction recording unit 50 converts the appropriate signal. To be played back on the TV 60.

When the search mode is selected, the capstan motor 90 is driven according to a predetermined double speed to change the tape feed speed. When the still image is reproduced, the capstan motor 90 is stopped and only the drum motor 80 is rotated.

The configuration of such a VCR is the same as that of a conventional VCR, but the present invention is to play back a still image every predetermined time in the search mode.

That is, the present invention performs a search operation and counts the search time when there is a search switch input during the play operation;

When the search operation is performed for a certain time, the process of playing back the still image and counting the still image playback time,

When the still picture playback time elapses, the search operation is performed and the search time is counted.

If there is a switch input other than the search mode while performing a search operation or playing a still image, perform the corresponding switch function.

This process of performing the operation will be described with the flowchart of FIG.

First, check the play switch input (S100), if it is not the play switch input, exit the program and execute the main program.

If regeneration switch input, regeneration operation is performed and check whether search switch is input. (S101)

The search switch may be either a forward search switch or a reverse search switch.

In this way, if there is no search switch input during the reproducing operation, the search mode is not performed. Therefore, the reproducing operation is continued. If there is a search switch input during the reproducing operation, the search mode is performed. Count the execution time. (S103)

Performs a search operation and checks when the search time counting the search operation is equal to or greater than the set time. (S104)

At this time, the setting time can be set in advance when the set is produced or can be changed by the user, but the setting time is about 10 seconds.

At this time, if the search time is smaller than the set time, check the switch input again (S108). If the search mode is continued, the search time is continuously counted.

If the search mode is not running, the function corresponding to the input function switch is executed.

If the search time is less than the set time, the reason for checking the switch input is that the search time is less than the set time, but according to the user, there may be a search interrupt switch input.

Alternatively, there may be a power off switch input, so check other function switch inputs while performing a search operation.

However, if the search operation is continued without input of another function switch and the search time becomes greater than or equal to the set time (S104), the system switches to the still image playback mode (S105) to reproduce the still image.

At this time, the still picture is replayed and the still picture play time is counted to check whether the still picture play time has elapsed. (S106)

At this time, the fixed time during which the still image is reproduced can be set in advance during the production of the set or can be changed by the user, but the fixed time is 1-2 seconds.

That is, if the search operation continues for a set time, the still image is played but the still image playback time is performed only for a certain time.

After a certain time has elapsed, the still image playback operation is stopped, the search operation is performed (S107), and the process of checking whether there is a switch input is performed (S108).

Therefore, when the search operation is performed, the search operation is to replay the still image for a certain time every time the set time passes, to make sure the user recognizes the current screen, and then perform the search operation again and repeat the above operation. The search screen can be replayed every halfway through the search operation, making the screen navigation more certain.

In addition, the present invention performs a function corresponding to the input switch when the search mode is a switch input to check the switch input during the search operation or during the playback of the still image.

As described above, the present invention can easily and accurately find a desired scene by reproducing a still image every set time while performing a search operation.
