Claim Text:
1. A solid-state image pickup device comprising: first and second substrates on which circuit elements constituting a pixel are arranged; and a coupler electrically coupling the first and second substrates; wherein the pixel comprises: n photoelectric conversion elements on the first substrate where n is an integer of two or more, the n photoelectric conversion elements being configured to respectively generate n electric conversion signals; n amplifier circuits on the first substrate, the n amplifier circuits being configured to amplify the n electric conversion signals and output n amplified signals, respectively; n signal storing circuits on the second substrate, the n signal storing circuits being respectively associated with the n photoelectric conversion elements, the n signal storing circuits being configured to respectively store the n amplified signals; an output circuit on the second substrate, the output circuit being configured to sequentially output the n amplified signals respectively stored in the n signal storing circuits, as output signals from the pixel; and an analog-to-digital (AD) conversion circuit connected to the output circuit, the analog-to-digital (AD) conversion circuit being configured to convert the n amplified signals from analog signals into digital signals after outputting the n amplified signals from the n signal storing circuits, wherein the n photoelectric conversion elements are grouped into one or more groups based on arrangement positions thereof on the first substrate, and the coupler electrically couples a pixel output node to which the n amplified signals are output, to the n signal storing circuits.
