A time-of-flight distance measuring method and TOF distance measuring system. The distance measuring method includes: intermittently transmitting a plurality of pulses from a pulse generation unit; controlling a TOF sensor to allow each pixel of a plurality of pixels in the TOF sensor to continuously perform a first signal sampling first proportion for a first predetermined time on a first proportion of a plurality of reflected signals and performs a second signal sampling second proportion for a second predetermined time on a second proportion of a plurality of reflected signals, so as to generate a plurality of sampling results corresponding to the plurality of pixels; obtaining a plurality of depth information and a plurality of luminance information corresponding to the plurality of pixels according to the plurality of sampling results; and adjusting the first proportion and the second proportion according to the plurality of depth information and the plurality of luminance information.

Time-of-flight based distance measuring method and related distance measuring system

A time-of-flight distance measuring system includes: intermittently transmitting a plurality of first pulses, wherein the plurality of first pulses are reflected by a target to generate a plurality of first reflected signals; using a TOF sensor to selectively perform a first signal sampling or a second signal sampling upon the plurality of first reflected signals respectively to generate a first sampling result, wherein there is a first time difference between a starting time point of the first signal sampling and a transmitting time point of the corresponding first pulse, and the first signal sampling lasts for a first predetermined time, and there is a second time difference between a starting time point of the second signal sampling and a transmitting time point of the corresponding first pulse, and the second signal sampling lasts for second predetermined time, and the first time difference is smaller than the second time difference.
