Abstract

A computer-implemented method is provided. The method includes generating a measurement wave at a frequency lower than an audible range, the measurement wave being to be used for estimation of a temperature, generating superimposed control data by superimposing the measurement wave on control data for vibration of a voice coil motor, inputting the superimposed control data to the voice coil motor, obtaining a current value and a voltage value inside the voice coil motor to which the superimposed control data has been inputted, subjecting the obtained current value and voltage value to low-pass filter processing, calculating a resistance value inside the voice coil motor based on the low-pass filtered current value and voltage value, and estimating the temperature inside the voice coil motor based on the calculated resistance value.
