Abstract
A pixel array includes a plurality of pixels. Each of the pixels includes a photoelectric element formed on a substrate and that generates charge from light, and a pixel circuit formed between the photoelectric element and the substrate and that outputs a digital signal value based on an amount of the generated charge. The pixel circuit includes a floating diffusion formed in the substrate and that stores the charge therein, a vertical pixel electrode that connects the floating diffusion to the photoelectric element and extends in a direction perpendicular to the substrate, an analog-to-digital converter that converts an electric potential of the floating diffusion into the digital signal value, and a memory element that stores the digital signal value.
