Abstract
A pulsed image capturing system includes a pulse generation circuit, a dynamic vision sensor (DVS), and a DVS scanning and readout circuit. A global reset signal is transmitted to pixels of the DVS to set a reference illumination level for the pixels, and then a pulsed light pattern is generated. A global hold signal is transmitted to the pixels, after the pulsed light pattern is generated, to hold an illumination change event indicating a change with respect to the reference illumination level. A DVS scanning and readout operation is performed on event signals received from the pixels, after the global hold signal is transmitted to the pixels. A reflection of the pulsed light pattern is extracted from the DVS output after cleaning artifacts from the DVS output without additional image processing.
