Abstract
Provided is an imaging element that comprises a first substrate and a second substrate. The first substrate including a plurality of detection pixels that generates a voltage signal corresponding to a logarithmic value of a photocurrent, and the second substrate including a detection circuit that detects whether the change amount of the voltage signal of a detection pixel indicated by an inputted selection signal among the plurality of detection pixels exceeds a predetermined threshold or not are stacked, and an element constituting the detection circuit is disposed in each of a first region on a back surface side and a second region on a front surface side of the second substrate. The present technology can be applied to, for example, an imaging element that detects an address event for each pixel.
