Therefore, the power source used for the camera can be used to supply the power necessary for the operation of the camera using a small portable power source that can be used in any place.

As described above, since the power source used for the camera is a low power portable power source, which is impossible to use for a long time, the photographer generally has an extra portable power source.

In order to realize advances in electronic technology and advanced cameras, many automated cameras currently being developed have many functions added to meet the needs of photographers.

Therefore, since more power consumption is required to perform various functions assigned to the camera, the use time of the portable power built in the camera is gradually decreasing.

However, there is no separate function or device to reduce the power consumption of the built-in camera currently being developed and marketed. Therefore, a constant power is always supplied to each device regardless of the operation mode or state of each camera selected. Consume.

Therefore, if the device does not directly affect the camera's shooting operation, if the camera is in standby for shooting without actual shooting, or if the barrel moves to each set position in order to shoot a subject that meets the shooting conditions. In addition, the power supplied to control the operation of the barrel is constant, and operates at a constant driving speed or state set regardless of the operation state of the camera.

Therefore, unnecessary current leakage or consumption occurs, thereby accelerating the consumption of portable power.

Therefore, an object of the present invention is to solve the above-mentioned problems, and extends the use time of the portable power supply by changing the value of the current consumed according to the operating state of the camera or the shooting conditions, thereby reducing unnecessary current consumption or leakage current. The present invention provides a device for minimizing current consumption of a camera and a control method thereof.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an apparatus for minimizing current consumption of a camera according to an exemplary embodiment of the present invention, and FIGS. 2a to 2c are flowcharts illustrating an operation method of minimizing current consumption of a camera according to an exemplary embodiment of the present invention.

Referring to FIG. 1, a configuration according to an exemplary embodiment of the present invention will be described. The operating state is changed manually, and the main switch 11 for switching the state of the camera can be photographed, and the operating state is manually changed. In order to shoot the subject, the variable shooting switch 12 for shooting the subject and the operating state are changed manually, so that the zoom in / out operation of the subject can be selected and executed respectively. The zoom in / out switches 13 and 14, the operation state is changed manually, and the fine adjustment switch 15 for allowing the user to arbitrarily adjust the magnification of the zoom in / out, the switches 11 to 15, Connected, and determines the operating state of the camera by using the operating states of the switches 11 to 15, and changes the state of the current applied to each corresponding control device according to the determined operating state, A camera controller 2 for changing the current consumption, a timer 21 connected to the camera controller 2 and operated by an enable signal applied from the camera controller 2 to count time; A barrel motor driving unit 31 connected to the camera control unit 2, the operation state of which is changed according to a state of a control signal output from the camera control unit 2, so as to change an operating speed of the camera barrel; It is connected to (2), the operating state is changed in accordance with the state of the control signal output from the camera control unit 2 is composed of a data display unit 32 that can change the output state of the data displayed in the finder of the camera .

A control method according to an embodiment of the present invention having the above configuration will be described with reference to FIG.

When a portable power source is mounted at a corresponding position of the camera, and power required for operation of each device is supplied, the camera controller 2 starts operation (S10).

Therefore, after initializing the variable used during the control operation (S11), the camera controller 2 reads a signal input from the main switch 11 to determine the operation state of the camera to determine the state of the main switch 11. (S11, S12).

The main switch 11 is a switch for switching the state of the camera to a state in which the photographing operation of the subject is possible after the power is supplied, and the operation state is manually changed by the user.

Therefore, when the state of the main switch 11 determined in the step (S13) is determined to be an off state, the non-operating state, the camera controller 2 determines that the state of the camera is not switched to the state for photographing the subject. To switch the power supply mode to the low speed mode (S39).

Therefore, since the actual photographing operation is not made, the operating speed of the barrel can be reduced by changing the period of the driving signal applied to the barrel motor driver 31 to control the operating speed of the lens barrel at the set low speed.

However, when the determined state of the main switch 11 is switched to the on state by the user, the camera control unit 2 may perform the photographing operation of the subject in accordance with the shooting conditions of the camera selected by the user. By controlling the operating speed of the barrel when the state or position changes or the information display state in the finder, it is possible to reduce the current consumption.

Therefore, the camera controller 2 reads the signals input from the zoom in / out switches 13 and 15 to determine the shooting mode selected by the user, and determines whether the zoom in or zoom out operation of the subject is selected. (S14, S15).

It is determined that the zoom-in or zoom-out operation is selected by the user, and the camera controller 2 reads the signal of the fine adjustment switch 15 to determine whether the zoom-in or zoom-out state can be arbitrarily adjusted by the user. Determine (S16).

In order to determine the fine adjustment state, as in the embodiment of the present invention, a separate fine adjustment switch 15 may be mounted or a fine adjustment operation at the time of zoom in / out control using a mode selection switch that is already mounted on the camera. You can also control.

Therefore, when the fine adjustment state for arbitrarily adjusting the magnification of the zoom-in or zoom-out, the camera controller 2 outputs a control signal corresponding to the barrel motor driver 31 to finely adjust according to the corresponding magnification so that the barrel is operated. If so, the operating speed of the barrel to maintain the medium speed (S17).

However, when the normal shooting state without the zoom control or the fine adjustment for the zoom in / out operation is not made, the camera control unit 2 allows the barrel motor drive unit 31 to be operated at a high speed at which the barrel is at a normal speed. The control signal of the corresponding state is output to control the operation (S18).

The camera controller 2 reads the signal output from the photographing switch 12 and determines whether the photographing switch 12 for operating the shutter is selected for photographing the subject (S19 and S20).

When the determined state of the shooting switch 12 is switched to the on state for photographing the subject, the camera controller 2 adjusts the operation speed of the barrel motor controller 31 to execute the photographing operation of the subject according to the set photographing conditions. In the high speed mode, the barrel is operated at a high speed in a normal state so that the safe photographing operation can be performed (S21).

Then, it is determined whether the photographing operation of one cut is completed by using the winding signal of the film (not shown) (S22).

When the determined shooting state is determined to be the shooting completion state, the camera controller 2 enables the timer 21 to operate by enabling the operation of the timer 21 to count the time (S23).

When the timer 21 is operated by the control signal of the camera controller 2, the camera controller 2 reads the signal output from the photographing switch 12 again to determine whether the photographing operation of the new subject is performed again ( S24, S25).

Therefore, when it is determined that the photographing switch 12 is turned on and the selection operation for photographing a new subject is performed again, the camera controller 2 proceeds to step S20 to determine whether the photographing operation of the subject is completed.

However, if it is determined that the photographing switch 12 is in the off state and the photographing operation of the new subject is not selected, the camera controller 2 reads the value of the timer 21 to determine the elapsed time after the photographing completion ( S26), and compares with the set time (S27).

When the determined time of the timer 21 has passed the set time, the camera control unit 2 is moving to a shooting location after the shooting of the cut in which the state of the camera is completed, or the next shooting is not performed quickly. To judge.

Therefore, the camera controller 2 displays only the most basically necessary data through the data display unit 32, and also controls the supply state of the power output to each corresponding device so as to control only the basic operation (S28).

Therefore, power is not supplied for the photographing operation of the subject such as a barrel, and only the most basic data such as a date and a market price are output to the data display unit 32.

In the state where the photographing operation of the subject has not been performed for a predetermined time as described above, the camera controller 2 is in a state of all unshown switches attached to the camera in addition to the signals of the switches 11 to 14 shown in FIG. It is read to determine whether the switch is operated by the user (S29, S30).

Therefore, when any one of the switches mounted on the camera is operated by the user and the corresponding signal is read, the camera control unit 2 releases the shooting standby mode set in the step S28, and thus the state of the timer 21. In order to initialize the photographing operation of the subject, the power required for the operation of each device is normally supplied to return the state of the data display unit 32 to the normal state, and the barrel may be operated (S31).

However, at this time, since the photographing operation of the subject is not performed, but only the state of the camera is switched to the photographing standby mode, the photographing operation is controlled by controlling the operation of the barrel motor driving unit 31 so that the driving speed of the barrel may be a medium speed. It is possible to reduce the consumption of unnecessary current by setting the speed of the barrel to be operated at the mode change mode.

Then, the state of all the switches attached to the camera is read again (S32), and when it is determined that at least one switch is operated (S33), the barrel is judged as an operation for photographing a subject so that the barrel can be operated at a high speed normally. The operation of the motor driver 31 is controlled to allow normal subject photographing to be performed (S34).

However, when the switch does not operate, the above operation is repeated to determine whether an operation for photographing a subject is performed within the set time using the timer 21 to prevent current consumption when the camera does not operate. S35 to S38).

Therefore, as described above, the camera controller 2 controls the supply of power supplied to each corresponding device when the camera does not perform an operation for photographing a subject for a predetermined time, so that the camera control unit 2 Preserving and outputting basic data and shutting off power to other devices can prevent unnecessary current consumption.

Therefore, normal shooting operation can be made.

However, when the speed of the lens barrel is controlled according to each shooting condition required by the user, and the photographing operation of the subject is performed according to the condition, the camera controller 2 can safely photograph the subject of the operating speed of the barrel. Always control at high speed to ensure safe shooting.

The effect of the present invention operating as described above is to supply only the power for preserving and outputting only the data necessary for the operation when the photographing operation of the subject is not made for a certain time, cut off the supply of power applied to other devices, zoom Even when the barrel is operated for in / out operation, the barrel's operating speed can be lowered than the normal speed and the limited power consumption of the camera can be reduced.

In addition, the power supply to each device is controlled according to the operation state of the main switch, thereby preventing unnecessary power consumption.
