Abstract
Solid-state imaging elements that accommodate expanded dynamic range are disclosed. In one example, a conversion efficiency control transistor controls conversion efficiency during conversion of a charge into a voltage by opening and closing a path between a floating diffusion layer and an additional capacitance. An upstream amplification transistor amplifies the voltage generated from the charge according to the conversion efficiency, and outputs the voltage to a node. Capacitive elements hold the output voltage. A selecting circuit connects any of the capacitive elements to a downstream node. A downstream circuit reads out and outputs the held voltage via the downstream node.
