1. A method for detecting distance for use in an apparatus configured to measuring a distance, comprising:
executing a first distance measurement mode by using the apparatus, wherein the apparatus has an anti-vibration module;
executing a second distance measurement mode by using the apparatus when displacement of the apparatus is greater than a preset value;
when the first distance measurement mode is executed, electrically connecting the anti-vibration module to perform distance measurement to obtain a first distance measurement result, wherein the maximum movement compensation amount of the anti-vibration module is a first value; and
when the second distance measurement mode is executed, electrically connecting the anti-vibration module to perform distance measurement to obtain a second distance measurement result, wherein the maximum movement compensation amount of the anti-vibration module is a second value, and the first value is greater than the second value.
