The invention relates to a light detection apparatus and a vehicle control system. The purpose of the present invention is to reduce the circuit scale in a solid-state imaging element that detects an address event. This solid-state imaging element is provided with a plurality of photoelectric conversion elements, a signal supply unit, and a detection unit. In the solid-state imaging element, each of a plurality of photoelectric conversion elements photoelectrically converts incident light to generate a first electric signal. In a solid-state imaging element, a detection unit detects whether or not a change amount of a first electric signal of each of a plurality of photoelectric conversion elements exceeds a predetermined threshold value, and outputs a detection signal indicating a detection result. 本公开涉及光检测装置和车辆控制系统。本发明的目的是减小检测地址事件的固态成像元件中的电路规模。该固态成像元件设置有多个光电转换元件、信号提供单元和检测单元。在该固态成像元件中，多个光电转换元件中的每一个对入射光进行光电转换以产生第一电信号。在固态成像元件中，检测单元检测多个光电转换元件中的每一个的第一电信号的变化量是否超过预定阈值，并输出指示检测结果的检测信号。
