Abstract:
An apparatus and method is provided for controlling a stepping motor in a digital photographing apparatus, the apparatus including: a temperature measuring unit for measuring a temperature; and a digital signal processor (DSP) for determining a measured temperature driving value of the stepping motor in correspondence with the measured temperature, 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. Accordingly, power consumption of image capturing apparatuses may be eventually reduced by reducing power consumption of a stepping motor by driving the stepping motor with different driving values depending on temperatures and positions thereof.
