Document Type and Number:
WIPO Patent Application WO/2020/129954
Kind Code:
A1
Abstract:
A ranging/imaging device (1) is provided with: a timing control unit (100) which outputs one or more timing signals; a light-receiving unit (204) which receives reflected light, due to a subject, of light emitted from a light source (203) and outputs a signal used for measuring a distance to the subject; and a phase adjusting circuit (2) which, on the basis of the one or more timing signals, outputs at least one of an emission control signal which is used for emitting light from the light source (203) toward the subject, and an exposure control signal which is used for starting exposure by the light-receiving unit (204). The phase adjusting circuit (2) includes one or more DLL circuits for determining the phase, with reference to at least one of the one or more timing signals, of at least one of a rise edge and a fall edge of the at least one of the signals.
