Abstract
A solid imaging element (11a) according to an embodiment includes: a light reception element (402) that outputs an electric signal in accordance with incident light, a detection unit (30) that detects whether a change quantity of the electric signal output from the light reception element has exceeded a threshold, and outputs a detection signal expressing a detection result of the detection, a temperature measurement unit (51) that measures temperature, and a setting unit (52) that sets the threshold on the basis of the temperature measured by the temperature measurement unit.
