IMAGE SENSING SYSTEM AND METHOD THEREOF

This abstract first appeared for US patent application 20250130036 titled 'IMAGE SENSING SYSTEM AND METHOD THEREOF

Original Abstract Submitted

a method includes generating light pulses by an illumination source toward an object; collecting the light pulses reflected from the object by an image sensor; generating a first signal-time plot of a sensor signal by the image sensor; generating a second signal-time plot of an index signal, wherein the second signal-time plot of the index signal comprises pulsed signals corresponding to the light pulses, respectively; collecting data from selected time periods of the first signal-time plot of the sensor signal, wherein the selected time periods of the first signal-time plot of the sensor signal are the same as time periods of the light pulses in the second signal-time plot of the index signal; and generating a third signal-time plot of an output signal based on the collected data.
