Dot sight device having power saving functions, the control method thereof

A control method of a dot sight having power saving functions, the control method comprising:

• turning on a power switch which supplies power to the dot sight;
• performing an operation mode by turning on power of a dot visual chart generator of the dot sight;
• initializing a value of a timer;
• turning on the timer;
• comparing a value of the timer which is measured from when the operation mode is started with a predetermined value;
• if the value of the timer is greater than or equal to the predetermined value, performing a power saving mode by turning off the power of the dot visual chart generator of the dot sight;
• and
• performing a first movement sensing operation, which senses a movement of a gun through a vibration sensor in the power saving mode, and, if the movement of the gun is sensed, goes to the operation of performing the operation mode.

A control method of a dot sight having power saving functions, the control method comprising:

• performing a power saving mode by turning off power of a dot visual chart generator of the dot sight;
• checking a power switch, which, if the power switch is tuned off as a result of checking a state of the power switch, returns to the previous operation of performing the power saving mode, and, if the power switch is turned on, goes to an operation of performing an operation mode;
• performing the operation mode by turning on the power of the dot visual chart generator;
• initializing a value of a timer;
• turning on the timer;
• a timer sub-routine which compares the value of the timer with a predetermined value, and, if the value of the timer is greater than or equal to the predetermined value, goes to the operation of performing the power saving mode;
• and
• a vibration sensing sub-routine which senses a movement of a gun through a vibration sensor, if a movement is sensed in the operation mode, initializes the value of the timer, and, if a movement is sensed in the power saving mode, goes to the operation of performing the operation mode.
