LIGHT SOURCE DRIVING CIRCUIT AND DISTANCE MEASUREMENT DEVICE

To provide a light source driving device and a distance measurement device, capable of realizing more highly precise timing control with a relatively small-scaled circuit configuration.SOLUTION: The light source driving circuit pertaining to the present disclosure includes: a first delay circuit that imparts a delay at a first time resolution on the basis of a clock signal to an inputted signal; and a second delay circuit that is connected in series with the first delay circuit and imparts, to the inputted signal, a delay at a second time resolution having different precision than the first time resolution on the basis of the clock signal, and outputs the delayed signal as a signal for driving a light source.SELECTED DRAWING: Figure 1 【課題】より高精度なタイミング制御を比較的小規模な回路構成により実現可能な光源駆動装置および測距装置を提供する。【解決手段】本開示に係る光源駆動装置は、入力された信号に対してクロック信号に基づき第１の時間分解能で遅延を与える第１の遅延回路と、第１の遅延回路と直列に接続され、入力された信号に対してクロック信号に基づき第１の時間分解能と異なる精度の第２の時間分解能で遅延を与え、光源を駆動するための信号として出力する第２の遅延回路と、を備える。【選択図】図１
