Apparatus and method for controlling stepping motor

An apparatus for controlling a stepping motor, the apparatus comprising:

• a storage unit for storing temperature driving values of the stepping motor in correspondence with temperatures and storing divided-region driving values which are differently applied based on a moving section of the stepping motor;
• a temperature measuring unit for measuring a temperature;
• and
• a digital signal processor (DSP) for searching the storage unit to determine a measured temperature driving value corresponding to the measured temperature, searching the storage unit for a divided-region driving value based on a target position to which the stepping motor is supposed to move, and outputting the found divided-region driving value to the stepping motor.

A method of controlling a stepping motor, the method comprising:

• measuring a temperature;
• determining a measured temperature driving value of the stepping motor in correspondence with the measured temperature;
• and
• changing the determined driving value based on a target position to which the stepping motor is supposed to move and outputting the changed driving value to the stepping motor.
