Abstract
An imaging device includes a first pixel including a first photoelectric conversion region disposed in a first substrate and that converts incident light into first electric charges, and a first readout circuit including a first converter that converts the first electric charges into a first logarithmic voltage signal. The first converter includes a first transistor coupled to the first photoelectric conversion region and a second transistor coupled to the first transistor. The imaging device includes a wiring layer on the first substrate and includes a first level of wirings arranged in a first arrangement overlapping the first photoelectric conversion region and in a second arrangement overlapping the first and second transistors, the second arrangement being different than the first arrangement.
