BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera with a self-timer.

[0002]

2. Description of the Related Art It is well known that a self-timer is a shutter release after a predetermined time. It is known that the shutter release is normally performed only once for the setting of the self-timer, and the interval timer is used when the shutter release is performed a plurality of times.

[0003]

In the case of taking a group photo of a person, it is common to take a few pictures by changing the position of the person. However, as described above, since the shutter release is performed only once, the photographer has to make a round trip to and from the camera every time one frame is photographed. As a countermeasure, by using the interval timer, it is possible to shoot multiple times with one set, but the operation of this interval timer is complicated and it was extremely difficult for general laymen to handle. . In addition, the interval timer requires a large number of operating members, which complicates the circuit, which causes a cost increase and an increase in size.

The present invention has been made in view of the above-mentioned problems, and has a built-in self-timer which is easy to set when performing self-timer photographing a plurality of times and does not lead to cost increase or size increase. The purpose is to provide a camera. Another object of the present invention is to provide a camera with a built-in self-timer that does not require a special display member to let the photographer recognize that the self-timer shooting should be performed a plurality of times.

[0005]

In order to solve the above-mentioned problems, the present invention starts counting a predetermined time in response to a clock start signal in a camera with a built-in self-timer,
The shutter is released by at least one of a first self mode in which shutter release for one frame is executed upon completion of the time count, and a second self mode in which shutter release for a plurality of frames is executed at predetermined intervals. Self-timer means for performing release; release means for continuously performing shutter release for a plurality of frames regardless of the self-timer means; first display for indicating that the first self-mode is selected Section and a second display section for displaying that shutter release of a plurality of frames is continuously performed by the release means, and when the second self mode is selected, these first , And display means for displaying the second display portion.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a top perspective view of a camera according to a first embodiment of the present invention. In FIG. 1, a self-timer button 2 is provided on the left side of the upper surface of the camera body 1, and a liquid crystal display 3 is provided at the center.

The self-timer button 2 is for setting the self-mode, and in this setting state, the self-shooting is started by pressing the release button 4 arranged on the right side of the upper surface of the camera body 1. Is configured. As self modes, there are a single self mode in which self photography is performed only once after a predetermined time, and a multi self mode in which self photography is performed a plurality of times at predetermined time intervals.

The liquid crystal display 3 informs the photographer of information necessary for photographing such as whether or not self photographing is possible, a flash photographing setting mode, and the number of film feeds. FIG. 2 is a block diagram of the self-timer device according to the first embodiment. In the block diagram of FIG. 2, the microcomputer 100 includes a CPU, a memory, an I / O port, and a timer circuit. And the microcomputer 10
An input / output terminal of the counter 200 is connected to the input / output port of 0. This counter 200 is originally a microcomputer 1
00, but it is shown as a separate circuit here. Input terminals of the shutter control circuit 300 and the display circuit 400 are connected to the output ports, respectively. The counter 200, the shutter control circuit 300, and the display circuit 400 are the microcomputer 10 that responds to the closing of each switch Sw.
It is configured to operate according to a command of 0.

Here, each switch will be described. Sw1
Is a release button switch, and when the release button is pressed, O
N is done. Sw2 is a self-timer button switch, which is turned on when the self-timer button is pressed. Figure 2
In the above, the counter 200 converts each pressing of the self-timer button 2 into a pulse signal and counts the number of pulses.

The shutter control circuit 300 drives and controls the shutter and starts its operation in response to a control signal from the microcomputer 100. The display circuit 400 causes the liquid crystal display 3 to display information necessary for shooting, such as whether or not self-shooting is possible, a flash shooting setting mode, and the number of film feeds. The operation of the camera having the above configuration will be described.
When the self-timer is photographed, for example, when the self-timer button 2 is pressed twice, the self-timer switch Sw2 is turned on twice. The pressing of the self-timer button 2 twice means that the self-shooting is continuously performed twice, that is, the shooting is performed in the multi-self mode. When the self-timer switch Sw2 is turned on twice, the number of times the self-timer button 2 is pressed “2” is counted by the counter 200. Next, the microcomputer 100 that responds to the turning on of the self-timer switch Sw2
The display circuit 400 is controlled. As a result, the liquid crystal display 3 displays 3a and 3b as the self-mode display to inform the photographer that the multi-self mode is set. Then, when the release button 4 is pressed, the release button switch Sw1 is turned on, and the microcomputer 100
The shutter control circuit 300 is operated in response to ON of w1, and the first shutter release is performed after the elapse of the predetermined time T1. Furthermore, when one frame is rolled up,
After the elapse of the predetermined time T2, the second shutter release is performed. When the self-timer button 2 is pressed three times and four times more, the self-timer switch Sw
2 is turned on three times and four times, and the liquid crystal display 3 displays 3c and 3d as the self-mode display. Regarding this self-mode display, the display marks 3a to 3d are erased one by one with each shutter release, but instead of using these display marks 3a to 3d, the number of times of photographing is displayed by numbers, etc. Is possible.

Regarding the above-mentioned predetermined times T1 and T2,
Both T1 and T2 may be set as the same time,
The time T2 may be set shorter than T1 such that T1> T2. This is because the predetermined time T1 is considered as including the time required for the photographer to move from the camera to the shooting location, and the second and subsequent shootings do not require as much time as T1. Third time, 4
The second self-shooting is also performed at the same time as the predetermined time T2.

On the other hand, the self-timer button 2 is not pressed,
When the release button 4 is pressed, self-shooting is not performed, and the shutter is released as normal shooting. When the self-timer button 2 is pressed only once, the single self-mode is set, that is, self-shooting is performed only once after a predetermined time. In this way, setting of the multi-self mode in which a plurality of times of self-photographing are performed at predetermined time intervals can be easily performed by operating a single operation button, and no other operation member is required. Therefore, the size of the camera can be reduced by cost reduction and space saving.

Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 3 is a top perspective view of the camera showing the second embodiment. The difference between the second embodiment and the first embodiment is that in the first embodiment, the number of times of self-shooting is set according to the number of times the self-timer button is pressed, whereas in the second embodiment In this mode, the normal shooting mode, the continuous shooting mode, the single self mode, and the multi self mode can be switched by pressing the self timer button each time.

In FIG. 3, a self-timer button 12 is arranged at the center of the upper surface of the camera body 11, and a liquid crystal display 13 is arranged at the right side. The camera having the above-described structure operates in substantially the same manner as in the first embodiment, but in the second embodiment, the normal shooting mode and the single self-mode are sequentially pressed by pressing the self-timer button 12 once. The multi-self mode and the continuous shooting mode are switched to each other. When the self-timer button 12 is further pressed in the continuous shooting mode, the normal shooting mode is cyclically switched again. In the normal shooting mode, 1 even if the release button 14 is pressed.
When the shooting of the frames is completed, the shooting is terminated, and in the continuous shooting mode, shooting of a plurality of frames is continuously performed while the release button 14 is pressed. The liquid crystal display in each shooting mode is as shown in Table 1.

[0015]

[Table 1]

As described above, in the multi-self mode, both the self-timer display and the continuous shooting display are turned on to display that self-shooting and continuous shooting are performed. Therefore, it is possible to save the display space and cost without the need for separate display as the continuous self mode. In the above embodiment, the self-timer is set by pressing the self-timer button, and the self-shooting is started by pressing the release button. However, the self-shooting is started immediately by pressing the self-timer button. Some will be started. In a camera configured in this way, for example, the self-timer button
It is configured as a step push switch, and the first step is the number of frames setting and the second step is the self mode setting. Then, press the second step at a time to perform self-shooting for only one frame, and turn on only the first step for self-shooting for multiple frames.
The number of frames can be set by repeating ON / OFF, and then the second stage can be pressed.

In the multi-self mode of the present embodiment, the first shutter release is performed a predetermined time T1 seconds after the self mode is set and the release button is pressed, and the predetermined time T2 seconds are set. It is as described above that the shutter release is repeated sequentially after placing it.
In addition to this, various shooting conditions may be changed for each shooting.

For example, in a so-called bifocal camera in which it is possible to take a picture by selecting either the telephoto position (T) or the wide-angle position (W) of the taking lens with the T / W operation button, the first
It is possible to set the T / W shooting mode in which the second shooting is performed by either telephoto (T) or wide angle (W), and the second shooting is performed by the other of telephoto (T) or wide angle (W). You can also do it.

This setting operation will be described with reference to FIG. FIG. 4 shows a display in the T / W shooting mode setting. In FIG. 4, first, the self-timer button 2 is pressed twice to set the multi-self mode.
As a result, the self-mode display 23a and the continuous shooting mode display 23b are turned on to notify the photographer that the multi-self mode has been set. Then, when the T / W operation button 25 is pressed, the first focal length, that is, the telephoto (T)
Alternatively, either one of the wide-angle (W) display lights up, and the second
The other display of the focal length, telephoto (T) or wide angle (W) for the second time flashes. For example, if the first self-shooting is performed at the telephoto (T) and the second self-shooting is performed at the wide angle (W), the telescopic display 23c is lit,
The wide-angle display 23d blinks. Then, by pressing the release button 24, the self-timer operates as described above, and after the elapse of the predetermined time T1, the shutter release in the telephoto (T) is performed. The second shot, that is, the wide-angle (W) shutter release is started after a lapse of a predetermined time T2 from the first shooting. In the above, the first self-shooting was performed at the telephoto (T), but the wide-angle (W)
You can do it in.

By the way, in this case, the self-timer button 2 was pressed twice to set the multi-self mode accompanied by the focal length switching. However, the self-timer button 2 was pressed only once, and then the T / W operation button 25 It is also possible to set the multi-self mode with focal length switching by pressing. Further, both the self-mode display 23a and the continuous shooting mode display 23b are turned on, but the multi-mode setting is the self-mode display 23a and the telephoto display 23c at the same time.
Since the wide-angle display 23d can be identified by lighting and blinking, the continuous shooting mode display 23b can be omitted.

In the case where the photographic lens is capable of zooming, depending on the number of times of photographing in the multi self mode photographing,
The focal length of the taking lens may be changed little by little. In the case where the soft focus filter is insertable / removable into / from the taking optical path, for example, the first self-shooting is performed without the soft focus filter. The second self-shooting may be performed by inserting a soft focus filter. Alternatively, the self-shooting may be performed by gradually changing the exposure amount according to the number of times the self-timer button 2 is pressed.

[0022]

As described above, according to the present invention, the display of the multi-self mode in which the self-shooting is performed a plurality of times is commonly used as the mode display of the self-shooting and the mode display of the continuous shooting. Since it is not necessary to provide a means, cost reduction and space saving can be achieved.
