Abstract: A control device suitable for use in a time-of-flight sensor is provided. The control device includes a storage unit and a control unit. The storage unit records the count data corresponding to the photon trigger number of the time-of-flight sensor. The control unit is coupled to the storage unit. The control unit reads the count data, obtains the modulation ratio corresponding to the counting range according to the count data, generates a control signal corresponding to the modulation ratio of each counting range, and transmits the control signal to the time-of-flight sensor, so as to control the operation of the time-of-flight sensor.

Abstract: A data processing method that is suitable for use in a time-of-flight sensor includes the following steps. A processing unit reads a first stage of time-slot counting data corresponding to the time-of-flight sensor from a storage unit. The processing unit generates an overflow warning signal according to the first time-slot counting data and a first predetermined threshold. The processing unit reads a second stage of time-slot counting data, wherein the second time-slot counting data are greater than or equal to the first time-slot counting data, and the second time-slot counting data are generated by the time-of-flight sensor performing a sensing operation based on the first time-slot counting data. The processing unit subtracts a second predetermined threshold from the second time-slot counting data to generate a third stage of time-slot counting data or maintains the second time-slot counting data according to the overflow warning signal.
