JPH0818898A - Reproduction device for video floppy disk - Google Patents

Abstract

PURPOSE:To obtain a reproduction device for a video floppy disk at a low cost and with a saved space without need for a stop button by stopping the reproduction mode through the simultaneous depression of a reproduction forward button and a reproduction rewind button. CONSTITUTION:A CPU 17 controls each circuit based on the key operation of a key button 13 and the entire camera system. When the reproduction is stopped, a reproduction forward button and a reproduction rewind button of the key button 13 are depressed simultaneously. Thus, the reproduction forward command and the reproduction rewind command are given to the CPU 14. When an AND processing of the reproduction forward command and the reproduction rewind command are given to the CPU 14, a reproduction demodulation circuit 7 is stopped to stop the reproduction of an image. When the image is stopped, since it is difficult to depress simultaneously the reproduction forward button and the reproduction rewind button, the CPU 14 controls the reproduction forward button and the reproduction rewind button so as to reject an input for a prescribed time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image reproducing apparatus for a video floppy disk which records an image with an electronic still camera, and more particularly to an operating means for stopping reproduction.

[0002]

2. Description of the Related Art Conventionally, when reproducing an image of a video floppy desk recorded by an electronic still camera, it is necessary to stop the reproduction for the following two reasons.

First, there is a case where power is wasted by continuing unnecessary reproduction. Electric power is required for the spindle motor, the reproducing circuit, etc. during reproduction, and particularly when reproducing with a camera having a built-in battery, the battery is exhausted and the battery cannot be used during shooting.

For the following reason, the head and the disk are always in contact with each other when the image is reproduced, and when the image is continuously reproduced for a long time, the disk surface is scratched. If the disc surface is scratched, the head output will decrease and the image quality will deteriorate. For this reason, it is desirable to stop the reproduction after a certain time.

In addition, as an operation for stopping the reproduction of an image in the conventional electronic still camera, there are a method of pressing the stop button to stop the reproduction and a method of pressing the power button to stop the power supply in a system without the stop button.

[0006]

However, these conventional methods for stopping the reproduction of images have the following problems.

In the former case, since the stop button is separately provided separately, the cost of the button and the switch is increased and the space for mounting the button and the switch is required, which is not suitable for downsizing.

In the latter case, since the power supply is stopped, the power must be turned on to reproduce the image again, a certain system control is required until the reproduction, and the user needs a long time before the reproduction. It was

[0009]

SUMMARY OF THE INVENTION In order to solve these problems, the present invention provides a playback advance button for instructing to advance a track of a video floppy disk by one frame and reproduce a recorded image. A playback return button for instructing to return the track of the video floppy disk by one frame and to play back the recorded image is provided. The playback feed button and the playback return button do not accept individual inputs for a predetermined time. Are set so that the image being reproduced is stopped by pressing the reproduction feed button and the reproduction return button at the same time.

[0010]

The present invention will be described in more detail with reference to the drawings. FIG. 1 is an external view of an electronic still camera that employs a method of pausing during reproduction. In the figure, a push-type reproduction feed button 2 and a reproduction return button 3 are provided on the upper surface of the electronic still camera 1.

FIG. 2 is a schematic circuit diagram of a recordable / reproducible electronic still camera. In the figure, the CPU 14
It controls each circuit based on the key operation of the key button 13 and also controls the entire camera system.

The video signal of the subject inputted through the lens shutter 4 and the CCD 5 is converted into a signal format recordable by the modulation recording circuit 6 and then recorded on a predetermined track of the video floppy disk 10 by the magnetic head 9. To be done.
Here, the magnetic head 9 is moved to a predetermined track by a head transfer device whose drive is controlled by the track feed circuit 8. Further, the servo circuit 11 controls the motor 12 to a predetermined rotation speed, and the video floppy disk 10 also rotates at a predetermined rotation speed.

Next, at the time of reproduction, the reproduction demodulation circuit 7 reproduces the image of the track recorded on the video floppy desk 10.

When the reproduction feed is instructed by the reproduction feed button of the key button 13, the CPU 14 is connected to the drive control of the track feed circuit 8 to feed the track frame by frame, and the next recorded image is reproduced.

When the reproduction return button of the key button 13 is instructed to return the reproduction, the CPU 14 connects to the drive control of the track feed circuit 8 to return the track frame by frame and reproduce the next recorded image. It

Here, in order to stop the reproduction, by pressing the reproduction feed button and the reproduction return button of the key button 13 at the same time, the reproduction feed instruction and the reproduction return instruction are issued by the CPU 1.
4 is input. The CPU 14 stops the reproduction demodulation circuit 7 and stops the reproduction of the image when the AND input of the reproduction feed instruction and the reproduction return instruction is input.

Also, since it is difficult for the user to press the play forward button and the play return button at the same time when the image is stopped, the play forward button and the play return button should not accept input for a certain predetermined time. , Are controlled by the CPU 14.

FIG. 3 is a flow chart for explaining the procedure of the reproducing method of the present invention.

The power is turned on (step 1) and the video floppy desk is attached (step 2). A reproduction feed button and a reproduction return button are selected to reproduce a desired image (step 3). It is judged whether or not the reproduction feed button and the reproduction return button are pressed (step 4). If the play forward button and the play return button are not pressed, the current operation is maintained.

When it is determined that both the reproduction feed button and the reproduction return button are pressed, the reproduction is stopped.

[0021]

As described above, according to the method for stopping the reproduction of the video floppy desk according to the present invention, the reproduction is stopped by pressing the reproduction feed button and the reproduction return button. Therefore, the stop button is separately provided. No need to
A low-cost, space-saving playback device for a video floppy desk can be provided.
