DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self mode setting device for a camera, which activates a self timer by operating a self button to perform a photographing operation.

[0002]

2. Description of the Related Art Conventionally, as a self-mode setting device of this type, a single self-mode is set in which, when the self-mode setting button is pressed once, one photographing operation is performed after a set time of the self-timer. When the button is pressed twice, the double self mode (continuous shooting mode) in which the shooting operation is performed twice in succession after the set time of the self timer is set, and after the single self mode or the double self mode is set by the self mode setting button. When the release button is pressed, the self-timer starts and the set self-photographing operation is performed.

[0003]

However, in such a conventional self mode setting device, the release button is operated after the single self mode or the double self mode is set by the self mode setting button. There is a problem that the operation for self-shooting is complicated because it requires two operations.

The present invention has been made in view of the above-mentioned conventional problems, and provides a self-mode setting device for a camera in which the self-mode can be set and the self-photographing can be started by operating only a self-button. The purpose is to do.

[0005]

In order to achieve this object, according to the present invention, a self-timer is activated by operating a self-button and a photographing operation is performed after a preset time of the self-timer. When the operation of the self button is started, a predetermined time starts to be counted, and when the operation of the self button is canceled within a time shorter than the predetermined time or when the operation of the self button is not performed within the predetermined time, the set time of the self timer is set. After setting the first self-mode for performing one shooting operation later and starting the self-timer, releasing the operation of the self-button for a time longer than the predetermined time or adding a new operation of the self-button within the predetermined time. When the operation is canceled, the second self mode in which the continuous photographing operation is performed a plurality of times is set after the set time of the self timer and the self timer is activated. Than it is.

In the second self-photographing operation, the first phototaking operation is performed after the time set by the self-timer, and the second phototaking operation is performed after a lapse of a predetermined time from the first phototaking operation. It is okay.

[0007]

In the self-mode setting device of the present invention having such a configuration, when the self-button is momentarily operated or once operated, the single self-mode (first self-mode) is set at the same time. When the self-timer is activated, and the self-button is held down for a predetermined time or more, or when the self-timer is pressed, for example, twice, the self-timer can be activated at the same time when the double self-mode (second self-mode) is set. The setting of the self mode and the start of the self timer can be performed only by the operation of the self button, and the self photographing operation becomes easy.

[0008]

FIG. 1 is a circuit block diagram showing an embodiment of the present invention. In FIG. 1, reference numeral 10 is a camera control circuit using a CPU, and for the camera control circuit 10, a half-press switch S1, a full-press switch S2, and a self-switch S.
3 are connected. The half-push switch S1 is turned on by a half-push operation of the release button to start a predetermined photographing sequence by supplying power to the camera control circuit 10. The full-push switch S2 is followed by the half-push switch S1 by a deep-push operation of the release button. When turned on, the shutter release operation allows a series of shooting operations to be performed.

Further, as will be apparent from the description below, the self switch S3 is set to a single self mode when the self switch S3 is operated for a short time by, for example, a self button, and the self switch S3 is continuously pressed for a predetermined time or longer. The double self mode is set, and the self timer built in the camera control circuit 10 is started at the same time when each self mode is set.

An AF control unit 12, an AE control unit 14, and a hoisting / rewinding driving unit 16 are connected to the camera control circuit 10, and a self mode is displayed to display a self mode setting state and a self photographing operation state. The LED 18 is connected. FIG. 2 is an operation flow chart showing the main routine of the photographing sequence in the embodiment of FIG.

In FIG. 2, when the self-switch S3 is turned on by pressing the self-button, the camera control circuit 10 is activated. First, the activation reset process is performed in step S100 and then the photographing condition such as the AF process is possible in step S200. Perform a series of processing. After performing AF processing or the like in step S200, it is checked in next step S300 whether or not the self-switch S3 is in the ON state. If the self-switch S3 is in the ON state, step S900
Proceed to the self-mode processing of. This self-mode process is shown in detail in FIG. On the other hand, the self switch S3 If off, checks the status of all the push switch S2 proceeds to step S 400.

[0012] proceeds to step S 500 when the full press switch S2 at step S 400 is off half push switch S1
Is checked, and if the half-push switch S1 is in the on state, the process returns to step S300 and step S300.
The process is repeated ~S 500. On the other hand, step S500
If the half-push switch S1 is turned off, the series of processing ends. When on the total push switch S2 is determined in step S 400, performs film winding process for the next shot in step S 700 after the end of shooting subjected to exposure by imaging operation proceeds to step S 600, thus to check the latched state of the double self mode in step S 800 when a series of photographing operations are completed, but the double self mode ends the series of processing when not latched, if the double self mode has been latched returns to the self-mode process in step S 900, so that a series of photographing operations by the film winding exposure step S 700 of step S 600 again through the self-mode process.

FIG. 3 is an operation flow chart showing details of the self-mode processing shown in step S9 of FIG. In FIG. 3, when the self-mode processing is performed by determining whether the self-switch S3 is turned on in step S300 of FIG.
First, in step S10, the self LED 18 is turned on, and then in step S11, it is checked whether or not the double self mode is in the latch state. If the double self mode is not in the latch state, the process proceeds to step S12 and the self switch D3.
Check the on state of.

[0014] Self-switch S3 is started seven second timer routine proceeds to step S13 when off in step S12, the time-up of the 7-second timer is monitored at step S 14, step S 15 when the 7-second timer times up
Then, the self LED 18 is switched from the previously lit up to the blinking. Subsequently, the 3-second timer is started in step S16, and it is determined in step S17 that the time of the 3-second timer is up.
The ED 18 is turned off, and the process proceeds to the second step S6 to perform the photographing operation.

That is, the processing from step S12 to step S13 in FIG. 3 to the photographing operation is a self-photographing operation by setting a single mode by determining that the self-switch S3 has been operated for a short time. on the other hand,
When it is determined in step S12 that the self switch S3 is turned on, the process proceeds to step S19 to start the 3-second timer, and in the next step S20, the on state of the self switch S3 is checked. If the self-switch S3 continues to be turned on, the process proceeds to step S21, and the time-up of the 3-second timer is monitored. If it is determined in step S3 that the self-switch S3 is off before the 3-second timer expires, the process proceeds to step S13. Go to single self mode.

On the other hand, if the self-switch S3 is continuously pressed for 3 seconds or more, it is determined in step S21 that the time of the 3-second timer has expired, the process proceeds to step S22, and the double self mode is latched. If the double self mode is latched in step S22, the self LED 1
8 is switched from the previously lit state to the blinking state to notify the photographer that the double self mode has been set.

Subsequently, in step S24, it is checked whether or not the self-switch S3 is turned off. When the self-switch S3 is turned off, the process proceeds to step S25 and self-LE is executed.
D18 is switched from blinking to lighting, and similarly to the case of the single self mode, the processes of steps S13 to S18 are performed and the process proceeds to step S6 of FIG. 2 to perform the first photographing operation.

When the double self mode latch is discriminated in step S8 of FIG. 2 by the first photographing operation, the process returns to the self mode processing of FIG. In this case, it is determined in step S11 that the latch in the double self mode is determined, the process proceeds to step S26 to release the latch state in the double self mode, the 2 second timer is started in step S27, and the process proceeds to step S14.

When it is determined in step S14 that the time of the 2-second timer has expired, the process proceeds to step S15, in which the self-LED 18 blinks to notify the photographer of the second photographing operation, and then in step S16, the 3-second timer is started. In step S17, it is determined whether the 3-second timer is up,
The process proceeds to step S18, the self LED 18 is turned off, and the process proceeds to step S6 in FIG. 2 to perform the second photographing operation.

As described above, in the self-mode processing of the present invention shown in FIG. 3, the self-switch S3 serves as a start-up switch for the self-timer, and when the self-switch S3 is turned on, the self-timer is started up and at the same time. When the operation time of the self switch is short, for example, 3 seconds or less, the single self mode in which one shooting operation is performed after the set time of the self timer is set. On the other hand, when the on-time of the self-switch S3 continues for, for example, 3 seconds or more, the self-switch S3 is continuously set to 2 after the set time of the self-timer.
You can set the double self mode to perform one shooting operation,
By setting the single self mode or the double self mode by turning on the self switch S3 by operating only the self button, the self timer can be activated and the self photographing operation can be performed.

FIG. 4 is an operation flow chart showing another embodiment of the self-mode processing of the present invention. In this embodiment, when the self-button is operated once, the single self-mode is set, and the self-button is pressed. The double self mode can be set by pressing the button twice within a predetermined time, for example, within 1 second. That is, step S in the operation flow chart of FIG.
When it is determined in 300 that the self switch S3 is turned on by the operation of the self button, the process proceeds to the self mode process of FIG. 4, the self LED is turned on in step S10, and the double self mode latch state is present in step S11. Check. If it is determined in step S11 that the mode is not the double self mode, the process proceeds to step S30 to check the ON state of the self switch S3.

When the self-switch S3 is turned off, the process proceeds to step S31 to start the 1 second timer. continue,
At the same time as checking the on-state of the self-switch S3 at step S32, the time-up of the 1-second timer is checked at the next step S33, and if the release switch is not turned on again before the time-up of the 1-second timer, go to step S13. Proceeding to step S13 of FIG. 3, the shooting operation in the single self mode is performed as shown in the processing from step S13.

On the other hand, if it is determined in step S32 that the second self-switch S3 is turned on before the one second timer times out in step S33, the process proceeds to step S22, in which the double self mode is latched, and in step S23 the self The blinking of the LED 18 informs the photographer that the double self mode has been set, and when it is determined in step S24 that the self switch S3 that was turned on for the second time is off, the process proceeds to step S25 to switch the self LED 18 from the blinking state to the lighting state. , And proceeds to step S13, and through the processing of steps S14 to S18 shown in FIG. 3, step S6 of FIG.
Proceed to and perform the first photographing operation.

By the first photographing operation, the latch state of the double self mode is discriminated in step S8 of FIG. 2, and when the process returns to the self mode processing of FIG. 4, the latch state of the double self mode is determined in step S11. As a result of the determination, as in the case of FIG. 3, the process proceeds to steps S14 to S18 through the processes of steps S26 and S27, returns to step S6 of FIG. 2 again, and the second photographing operation is performed.

As described above, in the self mode process of FIG. 4, pressing the self button once sets the single self mode and activates the self timer, while the self button is pressed twice within a predetermined time. The double self mode is set and the self timer is activated.
In the double self mode (second self mode) in the above embodiment, the 2 second timer of step S27 and step S6 of FIG. 3 from the end of the first photographing operation.
The second shooting operation is performed after 5 seconds by the 3-second timer of, and a time lag of 5 seconds is provided between the first shooting operation and the second shooting operation. Has made it possible to change the pose, but without setting a time lag between the first shooting operation and the second shooting operation, the self-timer has timed out in the double self mode setting state. A continuous shooting mode may be used in which the shooting operation is continuously performed twice.

[0026]

As described above, according to the present invention, the single mode (first self mode) or double self mode (second self mode) is set and the self timer is started by operating only the self button. Compared with the case where the setting of the self-mode and the start of the self-timer are performed separately, the self-mode shooting operation is easier and no mistakes are made in operation, and the person who is unfamiliar with the handling of the camera. However, it is possible to reliably perform the necessary photographing operation in the self mode.
