FIG. 3 is a block diagram showing the internal structure of a still video camera according to the present invention. The still video camera of this embodiment is an IC memory that is detachable from the camera body as a storage medium for recording captured image signals. In addition to using the card, it has a reproducing function of reproducing the image signal recorded in the IC memory card set in the camera body and outputting the reproduced image signal to the outside.

In FIG. 3, an optical image from a subject is formed on a CCD 4 (photoelectric conversion element) via a lens 1, a diaphragm 2 and an optical filter 3. The CCD 4 photoelectrically converts the optical image and outputs it as an electric image signal. Then, the electric image signal is input to the preprocessing circuit 6 via the buffer 5 and is subjected to various processing in the preprocessing circuit 6.

The pre-process circuit 6 comprises a double correlation sampling circuit (CDS circuit) 6a, a knee circuit 6b, an amplifier 6c, a clamp circuit 6d and the like. The output from the preprocessing circuit 6 is converted into a digital signal by the A / D converter 7, and the γ correction,

It is sent to the memory card slot 14 and recorded in an IC memory card as a storage medium (not shown).

The reproduced image signal from the IC memory card proceeds in the opposite direction to the signal flow at the time of recording, is subjected to expansion processing by the compression / expansion processing circuit 12, and then passes through the memory interface 9. Is sent to the image reproduction circuit section. In the image reproduction circuit part, the digital image signal sent is returned to an analog signal by the D / A converter 15,
After passing through the clamp circuit 16, the color separation circuit 17 outputs R, G, B
The three primary color signals are separated.

Further, in the still video camera of this embodiment, various information is provided to the reproduced image signal sent to the LCD monitor 20 attached to the camera and the video signal output to the outside through the post process circuit 24. A character generator 40 and a character generator memory 41 for synthesizing and outputting are provided. 4 and 5 show
FIG. 4 is a perspective view showing an external appearance example of a still video camera having the internal configuration shown in FIG. 3, in which a taking lens 1, an optical finder window 50, and a flash are provided on the front surface of a camera body 49.
51 and a microphone 52 are provided, and the taking lens 1 and the microphone 52 are protected when not in use by closing the slide cover 53 in the direction A in the figure. The slide cover 53 may also function as a power switch.

A shutter switch 54 and an IC memory card insertion port 55 are provided on the upper surface of the camera body 49. Furthermore, on the back of the main body, L that displays various shooting information
CD display unit 33, various operation switches 28, LCD monitor 20 for displaying reproduced images, optical finder 56, video output terminal
57 and a voice output terminal 58 are provided.

In the configuration shown in FIG. 3, the circuit configuration for voice recording is omitted, but the voice signal obtained by the microphone 52 may be recorded in the IC memory card together with the image signal. As the various operation switches 28, a switch for selecting various modes, an up / down switch for instructing the number of frames of an image to be reproduced, an execute / cancel switch, etc. are provided.

The LCD display section 33 is constructed as shown in FIG. In FIG. 6, four triangular marks vertically arranged at the left end indicate the shooting modes of single shooting, low speed continuous shooting, high speed continuous shooting, and self-timer shooting. The display unit including six 7-segment displays provided in the lower portion is used for displaying various information such as date and time. The battery mark indicates the consumption status of the built-in battery, the clock display on the upper left indicates the operating status of the self-timer, and the display consisting of the arrow and the letter A on the right side of the self-timer display indicates the auto strobe mode. Indicates. The display section consisting of two 7-segment displays on the upper right is a section showing the number of frames of the reproduced image.

Further, three triangular marks vertically provided on the right end indicate a photographing mode, a reproduction mode, and a party mode from the top, and any one of them can be selected by a switch operation. It is like this. In the party mode, when shooting is performed based on a predetermined shooting trigger signal, the latest shot image is continuously and automatically played, and the image playback is repeated until the next shooting trigger signal is generated. The recording / playback automatic switching mode (the mode function corresponds to the recording / playback automatic switching means), and the shooting trigger signal includes not only a normal shutter switch or a remote control release operation but also an automatic shooting at fixed time intervals (interval shooting). ), Or automatic shooting control based on the input sound level of the microphone 52 can be used.

The photographing mode is a mode in which only the photographing operation is normally performed, and the reproducing mode is a mode in which the image signal stored in the IC memory card is reproduced in accordance with the instruction of the number of frames. It is also a mode that allows you to erase the image that was played. The party mode is used at a party venue as shown in FIG. 7, for example. Here, the camera body 49 is fixed to the tripod 61 toward the center of the party venue, and the camera body 49 and the large monitor 62 are connected by the cable 63 so that the reproduced image of the camera is displayed on the large monitor 62. I am trying to do it.

If the party mode is selected and the shutter is set to be released when the input sound level of the microphone 52 exceeds a predetermined level, for example, every time the party operates, the camera is directly operated. Even if there is no person, the pattern of the party venue can be sequentially displayed on the large-sized monitor 62 to be enjoyed. Next, the display control and the recording control when the IC memory card as the storage medium is used up in shooting using the still video camera described above will be described with reference to the flowchart in FIG.

First, it is judged whether or not the photographing mode or the party mode is selected (S1). When the photographing mode or the party mode is selected,
It is determined whether the set IC memory card is used up and the storage capacity is below a predetermined value, that is, whether the recorded image is full from the state where no image is recorded (S2). . The part of S2 corresponds to the storage capacity detecting means.

Here, if the IC memory card has a storage capacity sufficient to store at least one screen, the image signal normally shot based on the shooting trigger signal is recorded in the empty portion of the IC memory card. The normal shooting control is executed (S3). On the other hand, when the IC memory card is full, as shown in FIG.
A display for warning the memory full state is displayed on the display unit 33 (S4). In FIG. 9, “FULL” is displayed using the 7-segment display of the LCD display unit 33, and this is a display for warning that the storage capacity has been used up.

Then, it is judged whether or not the party mode is selected (S5), and if it is the party mode, a warning "F
The characters "ULL" are generated by the character generator 40 and combined, and "FU" is displayed on the playback screen displayed on the screen of the monitor 62 connected to the camera, as shown in FIG.
By superimposing the character "LL", a warning of the storage capacity is issued to the reproduced image (S6). The part of S6 corresponds to the storage capacity warning means.

At this time, the character "FULL" is superimposed on the playback screen on the LCD monitor 20 attached to the camera. In the above, the storage capacity is warned by using the character "FULL", but the present invention is not limited to this character, and if it is within a range in which the content of the warning can be understood, Japanese or pictograms can be used. It may be. Thus, it is difficult to confirm the small "FULL" display on the LCD display unit 33 on the camera body or the LCD monitor 20 as shown in FIG. Is installed in order to show the reproduced image to the participants of the party, and it is installed in a position that is easy to see in the party venue.
If the letter "L" is superimposed, it can be easily confirmed that the memory of the camera is full even if it is far from the camera.

On the other hand, in the normal shooting mode instead of the party mode, a buzzer sounds to warn that the memory is full (S7), and the "FULL" display on the LCD display section 33 cannot be confirmed. Even let the photographer notice that the memory is full. Even in the party mode, the buzzer may sound with a superimpose of "FULL" characters on the playback image to warn the user. However, in order to prevent the buzzer from interfering with the party, this implementation has been implemented. In the example, the buzzer is not used as a warning means in party mode.

When the memory becomes full as described above, normally, the IC memory card that is set is replaced with another IC memory card with a remaining storage capacity, or the IC memory card that is set is replaced. It is necessary to erase unnecessary ones of the recorded images to make a space, but in the present embodiment, the recorded images are sequentially updated without performing the erasing operation only in the party mode. A recycle mode is provided for updating and recording recorded images. The function of this recycle mode corresponds to the update recording means.

That is, if the recycle mode is selected, when the memory becomes full due to shooting in the party mode, the oldest image among the images recorded in the memory is updated to a new image in order. Even if the camera is left as it is, recording is not impossible, and only the image captured recently is left in the memory.

Especially when used in the party mode, it is not necessary to store the image signal for a long period of time, and a relatively recent image is often required even when a past captured image is required. The recycle mode as described above can be selected only when it is the party mode. So when the memory is full in party mode,
It is determined whether the recycle mode is selected (S
8) When the recycle mode is selected, the self-timer mark, which is a mark indicating that the recycle mode is selected, is displayed on the character generator as shown in FIG. It is combined with the output video signal and superimposed on the image on the monitor 62 (S9). At this time, the mark of the self-timer is also superimposed on the playback screen on the LCD monitor 20 attached to the camera. The above-mentioned step S9 corresponds to the update recording operation display means.

In this embodiment, when the recycling mode is selected in the party mode, the self-timer display of the LCD display unit 33 of the camera is turned on as shown in FIG. 12, and this is the recycling mode in the party mode. Since the selected state is shown, the self-timer mark is also displayed on the monitor (see FIG. 11), but characters such as “recycle” may be displayed.

When the fact that the recycle mode is selected is displayed on the monitor 62 as described above, the "FUL" is displayed.
As with the “L” indication, it can be surely notified that the recycle mode is selected, and if the user of the camera requests the selection of the recycle mode, the camera does not need to worry about the memory capacity and the camera can be used as it is. You can easily confirm that you can leave it.

When a photographing trigger signal is generated in the recycle mode (S10), the oldest image stored in the IC memory card at that time is updated to the latest photographed image and the latest image is recorded (S11). This S11 part corresponds to the update recording means. In the recycle mode, "FULL" may be displayed on the reproduced image only when the memory is first full.

In the party mode in which the above recycling mode is not selected and in the normal photographing mode, when the memory is full, even if a photographing trigger signal is generated, photographing / recording is performed as it is. However, it is necessary to prompt the user to erase the image or replace the IC memory card. Therefore, when a shooting trigger signal is generated in the party mode in which the recycle mode is not selected and the normal shooting mode (S12), shooting is performed due to insufficient storage capacity in the LCD display unit 33, for example, as shown in FIG. It warns that it is impossible (S13).

In FIG. 13, turning on all the middle horizontal segments of the 7-segment display of the LCD display unit 33,
It gives a warning that shooting is not possible. At this time, if the party mode is set (S14), the reproduced image is set to the mute screen (S15) to surely inform the user of the camera that an erasing operation or memory replacement is necessary.
The portion of S15 corresponds to the photographing impossible warning means, but when recording cannot be performed due to insufficient storage capacity even if the photographing trigger signal occurs, the image reproduction at the previous photographing is continued as it is, and the photographing is performed on the reproduction screen. It is also possible to display a message indicating that the operation could not be performed.

In the normal shooting mode,
A buzzer sounds (S16) to warn that photography could not be performed due to lack of storage capacity, and informs that image deletion or memory replacement is required. In the shooting mode, the warning buzzer will sound both when the memory is full and when the shooting trigger signal is generated when the memory is full, so you can change the tone of both buzzers. It is preferable to be able to distinguish them.

By the way, as a normal erasing operation for erasing the recorded image on the IC memory card, the reproduction mode is selected, the erased image is reproduced by instructing the number of frames by the up / down switch, and the reproduced image is erased. The image is erased one by one by judging whether it is good or not.
At this time, on the LCD display section 33, as shown in FIG. 14, "DELETE" indicating an erase mode by image selection is displayed.
Is displayed.

In this embodiment, a mode in which the image can be erased is set in the shooting mode and the party mode other than the reproduction mode.
It has a last (latest) image erasing mode that can be used in the party mode or the normal shooting mode, and a batch all erasing mode that can be used only in the party mode. Thus, as described above, when the memory becomes full during shooting, the troublesomeness of switching to the reproduction mode and erasing the image while checking the erased image can be eliminated.

When the batch all erase mode is selected, as shown in FIG. 15, the LCD display section of the camera is displayed.
"DEL ALL" is displayed by the 7-segment display of 33, and when the last (latest) image erasing mode is selected, as shown in Fig. 16, "DEL ALL" is displayed.
"AST" is displayed. Also, in playback mode,
In addition to the erasure based on the selection of each screen as described above, the batch erasure and the latest image erasure can be performed.

Next, control of image erasing in the photographing mode or the party mode will be described with reference to the flowchart of FIG. First, it is determined whether it is the party mode (S21), and when it is the party mode, it is determined whether it is the recycle mode (S22). If the batch all erase mode is selected in the party mode and the recycle mode (S23), the ICs set based on the erase execution trigger (S24).
All stored images on the memory card are erased at once (S25).

That is, when the recycle mode is selected, it is presumed that the recycle mode is selected because there is no original request for saving the image. Therefore, the above-described erased images are not collectively checked without confirmation. Erase is allowed. On the other hand, if the batch erase mode is not selected even in the party mode and the recycle mode, or in the normal shooting mode (S26), it is determined whether or not the last (latest) image erase mode is selected. (S2
7).

When the last (latest) image erasing mode is selected, if an erasing execution trigger occurs (S2
8) Erase the most recently recorded image (the most recently recorded image) among the image signals stored in the set IC memory card (S29). If the batch erase mode is not selected even in the party mode,
In the normal shooting mode, it is assumed that it is necessary to confirm the erased image, but if the image was taken recently,
It is presumed that it is possible to determine whether or not the image can be erased without actually reproducing and confirming the image. Therefore, as described above, only the last image can be erased.

On the other hand, when it is neither the party mode nor the shooting mode and is in the reproduction mode, which one of the modes of erasing by selecting one screen at a time, erasing all at once, and erasing the latest image is selected. Depending on,
The erase operation is executed (S30). As shown in the flowchart of FIG. 17, in the party mode, when the recycle mode is selected, the batch all erase mode,
You can select the latest image deletion mode,
Further, in the photographing mode, only erasing in the latest image erasing mode can be executed, and the function shown in the flowchart of FIG. 17 corresponds to the latest image erasing means and update recording erasing control means.

If erasing in the latest image erasing mode is continuously executed, all the images in the IC memory card can be erased, but in the normal photographing mode, the power switch of the camera is turned on and the IC memory card is turned on. If you add a restriction (image selection delay time) so that you cannot trace back to the recorded image immediately when the contents of the are searched and the camera is ready to shoot, important images will be erased by mistake. You can avoid the fear of being lost.

In the above, as shown in FIGS. 14 to 16, the erase mode display is shown using a 7-segment display. However, as shown in FIGS. 18 to 20, the erase mode dedicated display section is used. May be provided on the LCD display unit 33. Figure 18
Shows a state in which all the displays in the erasing mode are lit, although there is no actual display state, and FIG. 19 shows the reproduction mode in which the image selective erasing mode (SELECT) and the latest (last) image erasing mode ( LAST), batch erase (AL)
L) is selectable, and here, the latest (last) image erasing mode (LAST) is selected. In addition, in FIG. 19, the display of “SELECT” and “ALL” is not enclosed by a square, but this is
Indicates that the mode is not currently selected but can be selected.

FIG. 20 shows the party mode,
The erase mode in a state in which the recycle mode is not selected is shown. In this case, in the present embodiment, since the image selective erase mode (SELECT) and the batch all erase (ALL) cannot be selected, "SELECT" and "ALL" are displayed. Disappears, and the selected state of the latest (last) image erasing mode (LAST) is shown.

By the way, in the case of the present embodiment, selecting and erasing an arbitrary image is permitted only in the reproduction mode. However, for example, the memory is full while recording in the normal photographing mode. When it becomes necessary to erase the memory image, it is troublesome to perform the operation of switching to the reproduction mode by the mode selection switch to erase it and to return to the photographing mode again.

Therefore, for example, as shown in the flowchart of FIG. 21, it is preferable that the up / down switch for the number of frames can be used to switch to the reproduction mode and to return to the shooting mode. That is, when in the shooting mode (S
41) When the down switch for designating the frame number instruction to down is operated (S42), this is received as a switching command signal for switching to the reproduction mode so that the reproduction mode can be switched (S43).

In the reproduction mode, normally, an arbitrary frame (image) is selected and reproduced by the down switch and the up switch (S44), and if it is an erased image, an erase execution trigger is generated to select the selected image. Is erased (S46, S47). Here, when erasing is completed,
When the most recently captured image is selected with the up / down switch, and the next number of frames with no image recording is instructed by the up switch operation in this state (S45), this is considered to be a return command to the shooting mode. Then, the shooting mode is restored (S48).

Therefore, in the case of the above-mentioned format, even if the switch for switching between the shooting mode and the reproduction mode is not operated, the switching between the shooting mode and the reproduction mode is performed only by the up / down switch, and the erased image is selected. It is possible to improve the operability. In the above-described embodiment, in the party mode, the deletion of the image by the arbitrary selection is not permitted. However, if the deletion of the arbitrary selection image is permitted, the memory management becomes complicated and the image is easily deleted. This is because it is not suitable for the party mode in which you shoot and display them side by side in chronological order.

In the above embodiment, the 7-segment display on the LCD display section 33 of the camera is used to display "DEL" and "AL".
Although characters such as “L” and “FULL” are displayed, if a display device having more expressive power than the 7-segment display is provided, other characters or pictograms may be used to perform mode display or warning. .
