A time detection circuit may include: a delay unit configured to have a plurality of delay units, each of which delays and outputs an input signal, and start an operation at a first timing relating to an input of a first pulse; a latch unit configured to latch logic states of the plurality of delay units; a count unit configured to perform a count operation based on a clock output from one of the plurality of delay units; a count latch unit configured to latch a state of the count unit; and a latch control unit configured to enable the latch unit at a second timing relating to an input of a second pulse and cause the latch unit and the count latch unit to execute a latch at a third timing at which a predetermined time has elapsed from the second timing.
