An operation method of an optical sensor comprising receiving an ambient light by a light-sensing device. Record a signal generated by the light-sensing device after receiving the ambient light by a operation unit. A flicker frequency of the ambient light is determined by the operation unit. A signal operation parameter is set according to the flicker frequency, and the signal operation parameter comprises a sampling time difference, which is the starting time interval of two corresponding integration time periods of a plurality of integration time periods. Furthermore, the light-sensing device and the operation unit start the calculation of the intensity of the ambient light, so that the flicker component of an ambient light source may be eliminated from the light sensing result to produce a stable sensing result.
