Abstract: A solid-state imaging apparatus includes a pixel circuit and a negative feedback circuit. The pixel circuit includes: a photodiode; a charge storage that holds a signal charge generated by the photodiode; an amplification transistor that outputs a pixel signal corresponding to the signal charge in the charge storage; a first reset transistor that resets the charge storage; a first storage capacitive element for holding a signal charge; and a first transistor that controls the connection between the charge storage and the first storage capacitive element. The negative feedback circuit negatively feeds back a feedback signal corresponding to a reset output of the amplification transistor to the charge storage via the first reset transistor.

Abstract: A connection cable is provided with a plurality of structures, a first connector, and a second connector. The plurality of structures include a concave-shaped structure and a convex-shaped structure. The first connector includes the concave-shaped structure and the convex-shaped structure that are arranged in line symmetry with respect to a predetermined reference line. The second connector includes the concave-shaped structure and the convex-shaped structure that are arranged in line symmetry with respect to a predetermined reference line.
