SOLID-STATE IMAGING ELEMENT AND IMAGING DEVICE
Solid-state imaging elements are disclosed. In one example, an upstream circuit block generates a predetermined reset level and a plurality of signal levels each corresponding to an exposure amount, and causes capacitive elements, different from each other, to hold them. A selection circuit sequentially performs control to connect the capacitive element in which the reset level is held to a predetermined downstream node, control to disconnect capacitive elements from the downstream node, and control to connect the capacitive element in which any of the plurality of signal levels is held to the downstream node. A downstream reset transistor initializes a level of the downstream node when the capacitive elements are disconnected from the downstream node. A downstream circuit sequentially reads the reset level and the plurality of signal levels via the downstream node
