Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a system for recording/playing still images and audio captured using a still video camera.

(Background of the Invention) Conventionally, playback in a still video system is sometimes performed using a playback-only device, and sometimes using a camera with a playback function.

The functions of playback-only devices include the ability to send one frame at a time (or vice versa), and the ability to automatically send one frame at a time.
There is a function to advance one frame at a time (interval playback), a function to play a specific frame by specifying a track number, and a function to erase one frame at a time.

Cameras with a playback function only have a forward (reverse) playback function or a function to erase one frame at a time.

(Problems to be Solved by the Invention) The above-mentioned conventional technology only has simple playback functions such as forward playback, and therefore still video cameras have unique features (for example, instant playback functions) that are different from silver halide cameras. There is a problem that it is not easy to use because it cannot be said to be fully utilized and cannot respond to the needs of the diversifying market.

The present invention has been made in view of the problems of the prior art described above, and its purpose is to diversify the playback functions of a still video camera system and to make the system multifunctional by various new modes of playback. There is a particular thing.

(Means for Solving the Problems) The present invention is a system for recording still images or audio on a recording medium using a still video camera, or reproducing them from a recording medium, the system comprising: The present invention is characterized by having means for randomly extracting one or more still images or sounds from a plurality of still images or sounds, and displaying the extracted images on a display device.

(Function) A new shirtful function has been added that randomly extracts a portion of multiple images and sounds, making it possible to enjoy using the system as if it were a game by taking advantage of the immediacy of a still video camera. do.

This makes it possible to enjoy, for example, drawing lots or playing rock, paper, scissors games, etc.

This shirtful function, for example, includes a shirtful means having a random number table in the playback machine, and when the shirtful mode is selected by the mode selection means, a recording track is randomly selected using random numbers, and according to a command from the CPU. This is accomplished by controlling the playback head to move to a selected track position and reading out images or audio.

In addition, by adding an ID code (identification code) to the track in advance and decoding this ID code during playback and controlling the video output and audio output according to the instructions, even more diverse playback is possible. becomes possible. For example, it is possible to perform processing such as outputting audio first and then outputting an image immediately after that, or fixing the reproduced image to a pre-stored image to liven up the mood when a shirtful is being performed.

(Example) Next, an example of the present invention will be described with reference to the drawings.

Embodiment 1 FIG. 1 is a block diagram showing the configuration of a first embodiment of the still video system of the present invention, and FIG. 2 is a perspective view showing the overall configuration of this embodiment.

In FIG. 1, the playback device 46 is shown surrounded by a dashed line, and the other blocks belong to the still video camera main body. The system operation will be outlined below.

When a signal from the recording operation section 49 or the remote control receiving circuit 48 is input to the CPU 41, the sequence is started.

The lens 8. Aperture 9 etc. are adjusted. After this, the optical image signal of the object is transmitted to the lens 8. Aperture 9
The image is formed on an image sensor (CCD) 10 through an optical system such as the following. The video signal read from the CCD 10 by the COD drive circuit 11 passes through the CDS circuit 12, is separated into a luminance signal and a color signal circuit by the signal processing circuit 13, and is FM modulated by the FM modulator 15. After the DPSK-modulated ID code is superimposed by the mixing circuit 16, the selector 17, the recording amplifier 20 . It is recorded on the floppy disk 22 via the recording/reproducing head 21. ID code is CP during playback.
It is sent to U41 and controls the operation of the system.

Furthermore, the audio signal input from the microphone 1 is amplified by the amplifier 2, subjected to processing such as noise reduction by the signal processing circuit 3, and then once processed by the A/D converter 4.
It is converted into digital data and stored in the memory 5.

The data read from the memory 5 is D/A converted by the D/A converter 6, FM modulated by the FM modulator 7, and then sent to the selector 17. Recording amplifier 20. It is recorded on the floppy disk 22 via the recording/reproducing head 21. The record video signal and the record audio signal are selected by the selector 17.

An erase circuit 18 is provided for erasing the contents of the floppy disk 22, and the erase signal is selected by a selector 17.

The sequence of the reproduction operation during normal reproduction is also started upon receiving a signal from the remote control receiving circuit 48 or a signal from the operation section 49. First, an audio signal is read from the floppy disk 22, and the playback amplifier 26. FM? via selector 27? After being input to the Jj modulation circuit 33 and FM demodulated, the A/D converter 34
/D converted and temporarily stored in the memory 35.

Next, the video signal corresponding to this audio signal is read from the floppy disk 22, FM demodulated by the FM demodulation circuit 28, predetermined processing is performed by the signal processing circuit 29,
It is output continuously as a video signal.

While the video signal is being output, or during the period before and after that, the digital audio data stored in the memory 35 is read out at a speed that returns to real time, and is D/A converted by the D/A converter 36. The output circuit 38 outputs the signal as an audio signal.

Incidentally, these operations are collectively controlled by the CPU 41. The CPU 41 uses the main memory 44 to control each section. Also, the rotation of the floppy 22 (the motor 2
5 rotation) is the PG signal generation circuit 23° servo circuit 24
It is always stabilized by the control of

When a signal (mode signal) for selecting the shirtful mode is input to the mode selection circuit of the playback device 46 during shirtfull playback, the shirtfull execution means 43 randomly selects the audio or video recording track number using a built-in random number table. and reports the selected number to the CPU 41.

The CPU 41 instructs the head control circuit 19 to move the re-recording head 21 onto the corresponding track and perform reproduction.

During this reproduction, the ID code superimposed on the floppy disk 22 together with the video signal is separated by the selector 27 and sent to the CPU 41. The CPU 41 uses this ID
According to the instructions of the code, commands are sent to the memory 39 and mute circuit 40 to control the reproduction signal. For example, the memory 39 stores several types of characters and voices, and these signals are superimposed on the reproduced signal or output in place of the reproduced signal. This enables a variety of playbacks. In addition, mute circuit 4
0 cuts the video signal and also controls the background color etc. when there is no video signal.

The mute circuit 40 and the like need not necessarily be controlled by the ID code, but may be controlled directly by the CPU 41. In addition, when adjusting the output timing of the video signal in relation to the audio signal, an A/D converter 30. This is performed using the memory 31 and the D/A converter 47.

Specific example of control The case shown in FIG. 3(a) shows the case where one image is selected from among a plurality of human images, and after the shirt full mode is selected, one image is randomly selected and played. Until then,
The characters "5HUFFLE" stored in the memory 39 are displayed on the television 45 (state 70). After this, person A is selected and displayed (state 71).

In the case of Figure 3(b), the number is selected, and “5H
After "UFFLE" is displayed (state 80), "3" is selected and displayed (state 81).

In the case of FIG. 3(c), a game of rock, paper, scissors is displayed. After "5HUFFLE" is displayed (state 90), the background of the screen is fixed, and at the same time, the sound of "rock, paper, scissors" is stored in the memory 39. stored) is output (state 9
