The solid-state imaging device 1 includes an imaging photodetecting section 10, a trigger photodetecting section 20, a row selection section 30, a column selection section 40, a holding section 50, a pixel data output section 60, a trigger data output section 70, and a control section 80. The control section 80, when an absolute value of trigger data has changed into a state of being in excess of a first threshold, and then the state has continued for a predetermined time Ä 1 or more, judges it as a start of a light incidence, and starts a charge accumulating operation for each pixel unit, and when an absolute value of trigger data has changed into a state of being less than a second threshold, and then the state has continued for a predetermined time Ä 2 or more, judges it as an end of a light incidence, and causes a charge transferring operation and a data outputting operation to be performed for each pixel unit. Accordingly, a solid-state imaging device that can perform accurate imaging even for various applications and light incidence patterns is realized.
