A computation device, a sensing device and a processing method based on time-of-flight (ToF) ranging are provided. In the method, intensity information of at least two phases corresponding to at least one pixel is obtained. The intensity information is generated by sensing a modulation light with time delays using these phases. Whether to abandon the intensity information of the at least two phases corresponding to the pixel is determined according to the difference between the intensity information of the at least two phases. Accordingly, the influence caused by motion blur would be reduced on depth information estimation.

Computation device, sensing device and processing method based on time of flight

An exposure method and an image sensing device using the same are provided. The exposure method includes the following steps: obtaining a first light-intensity confidence value of each pixel unit based on a first exposure time; obtaining a second light-intensity confidence value of each pixel unit based on a second exposure time, wherein the second light-intensity confidence value is different from the first light-intensity confidence value; and taking the phase difference value, corresponding to one of the light-intensity confidence value and the second light-intensity confidence value of each pixel unit, as an output value of the corresponding pixel unit.
