The present invention relates to an operation control apparatus of a camera, and in particular, a self-timer shooting control apparatus for a camera which controls stable shooting to be performed in response to changes in side values before and after self-timer shooting during self-timer shooting and It relates to a control method.

Among the functions of the camera, the self-timer shooting function is a function that allows shooting to be performed after a predetermined time from the start of self-timer shooting, and is usually used when the photographer wants to target himself. For self-timer shooting, first, set the self-timer mode, manually operate the self-timer wait time, and release one-stage switch operation. Therefore, the camera performs the metering and metering according to the release one-stage switch operation. Shooting is performed after the set self-shooting waiting time has elapsed.

However, such self-timer photography is usually performed outdoors, the distance between the photographer and the camera is far, and the self-shooting wait time until the shooting is variable, so that undesired photography may be performed due to an unexpected situation. That is, there may be a case where another person invades the composition of the subject during the self-photographing waiting time, or the self-photographing waiting time does not satisfy the charging time during flash emission photography.

Therefore, conventionally, in order to solve the above problem, the first method of selecting double self or triple self-timer shooting during self-timer shooting, and shooting in an uncharged state when the distance measurement result during self-timer operation is sufficiently long. A second method of allowing this to be performed and a third method of extending the self-photographing waiting time by providing a separate switch for adjusting the self-photographing waiting time are known.

However, in the prior art, the first method and the third method must manually operate the multi-self function or separate switches, and the second method requires the subject to take the self-shooting waiting time due to the shooting operation according to the result of the measurement at operation. There is a problem that does not correspond to the movement.

 Accordingly, the present invention is to solve the conventional problem, and to perform the measurement before and after the self-timer operation, and compare the results of the two measurements so that the photographing operation to correspond to the movement of the subject during the self-shooting waiting time.

Self-timer shooting control apparatus of the camera according to a feature of the present invention for achieving the above object includes a release switch, self-shooting switch, ranger, self-timer, control unit.

The release switch outputs a release first stage signal which is manipulated by the photographer to start shooting, and a release two stage signal which allows shooting to be performed. The self-shooting switch is operated by the photographer to output a signal for starting self-timer photography. The ranger detects the distance between the camera and the subject and outputs it as a range signal. The self-timer is driven for a set time in accordance with the input control signal.

 If the output signal of the release switch is input while the single self-shooting mode is set according to the output signal of the self-shooting switch, the controller determines the first and second side values by driving the ranger before and after the self-timer driving. Then, the self-photographing control according to the difference between the first and second side values is performed by comparing the first and second side values.

Here, the self-timer photographing apparatus of the camera according to an aspect of the present invention preferably further includes a display unit which performs a display operation so that the photographer can check the self-photographing operation control according to the output signal of the controller. In addition, the self-timer photographing apparatus of the camera according to an aspect of the present invention preferably further includes a multi-self photographing switch that allows a user to select a corresponding multi-self photographing.

Hereinafter, with reference to the accompanying drawings will be described the operation of the red-eye reduction shooting control apparatus according to an embodiment of the present invention.

1 is a block diagram of a self-timer shooting control apparatus of a camera according to an embodiment of the present invention. As shown in FIG. 1, the self-shooting control device according to an exemplary embodiment of the present invention includes a self-shooting switch SW1, a release switch SW2, a light metering unit 100, a ranging unit 200, and a multi-shot count selection unit. 300, the control unit 400, the self-timer 500, the display unit 600, and the shutter unit 700.

Here, the self-photographing switch SW1 outputs a signal to the controller 400 to be operated by the photographer and to set the self-photographing mode. The release switch SW2 is operated by the photographer and outputs a release first stage signal S21 for starting photographing and a release two stage signal S22 for photographing to the control unit 400. The photometer 100 and the detector 200 are driven under the control of the controller 400 to detect the focusing information and the exposure information and output the detected information to the controller 400. The self-timer 500 is generally built in the control unit 400, but it is said that the self-timer 500 is mounted externally for the sake of understanding.

The multi-shot count selector 300 is operated by the photographer to generate a signal for setting the number of shots during the self-shooting compensation operation.

The controller 400 receives the switches SW1 and SW2 and sets the self-photographing mode, and outputs a control signal for driving the light meter and the light detector 100 and 200. When the self-shooting mode is set, the ranger 200 is driven according to the release first stage signal S21 to determine the ranged value. After that, the self-timer 500 is driven and the ranger 200 is driven again. Judge the mounting. Then, the side values determined before and after driving the self-timer are compared, and if the two side values are the same, normal self-timer shooting is performed. If the two side values are not the same, the shutter counts by the number of shots selected by the multi-shot number selector 300. The photographing is performed by driving the unit 700 at predetermined time intervals.

The display unit 600 may be a liquid crystal display, a light emitting diode, or both to display a corresponding message so that the photographer or the subject can check the self-photographing operation by driving according to a control signal of the controller 400 during self-capture. It is preferable to use both a liquid crystal display and a light emitting diode using a liquid crystal display for the purpose and a light emitting diode for the subject. Here, when the display unit 600 is a liquid crystal display device, a release switch lock, a release switch lock release, etc. are displayed during self-timer photography using a letter or a sign on the liquid crystal display device. Perform the function display for self-timer operation.

Hereinafter, the operation of the self-timer shooting control device of the camera according to the first embodiment of the present invention with reference to FIG. 2 will be described in detail.

2A and 2B are flowcharts illustrating operations of a self-timer shooting control apparatus of a camera according to a first embodiment of the present invention.

First, referring to FIG. 2A, as shown in FIG. 2A, when the photographer signals the self-shooting switch SW1 on, the controller 400 inputs an on-signal of the self-shooting switch SW1 to enter the self-timer mode. It is set (S10). In this case, the self-timer mode set by the controller 400 is a single self-timer mode in which self-timer photography is performed once.

 When the single self-timer mode is set, the control unit 400 outputs a driving signal to the light metering unit 100 and the metering unit 200 when the first stage signal is released, and the metering unit 100 and the metering unit 200 are controlled. The luminance signal of the subject detected by the driving and the ranging signal, which is the distance between the camera and the subject, are input and calculated to determine the primary side value and the luminance of the subject (S20 and S30).

Then, when the release two-stage signal is input (S40), the control unit 400 starts the self-timer 500 to start and checks the self-taking waiting time by receiving time information input from the self-timer 500. In operation S50, the display unit 600 controls the subject or the photographer to confirm that the self-timer is being photographed by driving the display unit 600.

The controller 400 stops driving the self-timer 500 when the checked self-photographing waiting time reaches a set time (eg, 10 seconds). Here, the self-shooting waiting time may be set to be fixed, or by installing a switch for setting the self-shooting waiting time may be changed by the photographer according to the self-shooting waiting time operation (S60).

When the self-photographing waiting time reaches 10 seconds, the controller 400 drives the light metering unit 100 and the ranger 200 again to determine exposure information together with the secondary side range (S70). Here, when the self-photographing waiting time is completed, the designer may drive only the ranger 200 again to obtain a secondary range value.

On the other hand, the control unit 400 compares whether the primary side value obtained and the secondary side value is the same (S80).

The comparison (S80) is for determining whether there is a movement of the subject during the self-photographing waiting time or whether an unintended object is invaded within the subject composition range. That is, if the primary side value and the secondary side value are the same, the control unit 400 determines that the normal self-timer shooting is not the same. It is judged that it occurred.

In the above, the controller 400 controls the photographing to be performed by driving the shutter unit 700 when the primary side value and the secondary side value are the same (S90).

Here, an operation of the self-timer shooting control apparatus of the camera according to the first embodiment of the present invention when the primary side value and the secondary side value are different will be described with reference to FIG. 2B.

As shown in FIG. 2B, when the primary side value and the secondary side value are different, the control unit 400 locks the release switch SW2 to prevent the first shooting from being performed (S81), and then doubles the single self-timer mode. Switch to the self-timer mode (S82).

At the same time as switching the double self-timer mode, a control signal is output to the display unit 600 to control that the set mode is switched to the double self-timer mode (S83).

Then, when the double self-timer is set, the control unit 400 releases the locking of the release switch SW2 (S84), and according to the double self-timer mode, two consecutive shots are automatically taken twice at intervals of a set time. Will be controlled). Here, the two consecutive shootings are determined by the user operating the multi-shot count selection unit 300 before the self-timer shooting. That is, the photographer operates the multi-shot count selector 300 before the self-timer shooting, that is, before setting the single self-timer mode, and the controller 400 when the first side value and the second side value are different during single self-timer shooting. Perform 2 consecutive shots. Here, the person skilled in the art can set the 2 continuous shooting or the 3 continuous shooting to the default value even if the photographer does not operate the multi-shot count selection unit 300.

The controller 400 first determines whether a predetermined time has elapsed for the second continuous shooting (S85). In addition, when the predetermined time elapses in the determination S85, the control unit 400 performs shooting according to the primary side value and the exposure value at this time (S86 and S90), and then whether the predetermined time elapses again. It is determined (S87).

In operation S87, when the predetermined time elapses, the controller 400 performs photographing again according to the secondary side value and the exposure value at this time (S88 and S90).

Therefore, according to the first embodiment, the present invention determines that the initial subject composition has been changed by comparing the side position immediately before the self-timer operation and the side position after the operation, and accordingly assumes that the subject is moving to the primary side position. According to the assumption that the subject is moved, the photographing according to the secondary side position is performed on the assumption that the subject is moved so that the desired photograph can be taken by the photographer.

Hereinafter, the operation of the self-timer shooting control apparatus of the camera according to the second embodiment of the present invention will be described with reference to FIG.

As shown in Fig. 3A and Fig. 3B, the second embodiment of the present invention is a first embodiment for obtaining distances before the self-timer operation and after the self-timer operation, that is, the primary side value and the secondary side value for self-timer photography. Has the same operation process as This process is shown in FIG. 3A and is the same as FIG. 2A.

However, the second embodiment differs from the first embodiment in that the self-timer shooting is controlled when the primary side value and the secondary side value are different. This will be described with reference to FIG. 3B.

As shown in FIG. 3B, when the primary side value and the secondary side value are different, the control unit 400 locks the release switch SW2 to prevent shooting from being performed first (S810), and then sets the single self-timer mode to multi ( multi) Switch to the self-timer mode (S820).

In addition, the control signal is output to the display unit 600 at the same time as the switching of the multi-self-timer mode to control that the set mode is switched to the multi-self-timer mode (S830).

Then, when the multi-self timer is set, the controller 400 releases the lock of the release switch SW2 (S840), and then automatically sets the number of shots set according to the multi-self timer mode. Here, the multi-shooting is performed according to the user's manipulation of the multi-shot count selecting unit 300 before the self-timer shooting. That is, the photographer operates the multi-shot count selector 300 before the self-timer shooting, so that the control unit 400 performs the multi-continuous shooting when the first side value and the second side value are different during the single self-timer shooting. At this time, select the number of multiple continuous shooting. Here, assume that the photographer has set the number of multi continuous shootings to three.

The controller 400 determines whether 3 seconds, which is a pre-determined time, has elapsed for the multi continuous shooting (S850). Then, when 3 seconds have elapsed in the determination (S850), the control unit 400 performs the photography according to the primary side value and the exposure value at this time (S860, S900), and then again determines whether 3 seconds have elapsed (S850). In operation S850, when 3 seconds have elapsed, the controller 400 performs photographing again according to the secondary side value and the exposure value at this time (S870 and S900).

Then, it is determined whether the predetermined 3 seconds have elapsed again (S850), and when 3 seconds has elapsed, the average of the first and second side values is calculated, and the shutter unit 700 is driven according to the calculation result. Shooting is performed (S880, S900).

The embodiments described above are only one of the most preferred embodiments for achieving the object of the present invention, and the present invention is not limited to the above embodiments. That is, a person skilled in the art can perform the first and second surveys before and after the self-timer and perform the third survey if the results of the first and second surveys are different so that the photographing is performed according to whether the third survey is the same as the first survey. Can be. In other words, when the third ranging result is the same as the first ranging result, the photographing is performed. When the third ranging result is the same as the second ranging result, the release switch lock is performed so that the shooting is not performed. On the other hand, it is easy for those skilled in the art to perform four or more surveys instead of the three surveys, and if the final measurement result is the same as the primary survey value, the photographing may be easily performed.

According to the present invention, a self-timer photographing operation is automatically performed to compensate for an involvement of an undesired subject within a range of subject movement or subject composition, thereby improving camera reliability, allowing a desired picture to be taken, and wasting film. prevent.
