Abstract: A solid-state imaging apparatus includes a pixel circuit, a detection and selection circuit, and an AD conversion circuit. The pixel circuit outputs a plurality of pixel signals corresponding to mutually different gains or sensitivities. The detection and selection circuit compares one or more of the plurality of pixel signals with a reference value to generate a signal selection signal that instructs selection of a pixel signal among the plurality of pixel signals. The detection and selection circuit includes a sample and hold circuit that holds the plurality of pixel signals, and selects at least one pixel signal among the plurality of pixel signals held in the sample and hold circuit based on the signal selection signal. The detection and selection circuit is arranged in a stage before the AD conversion circuit that AD converts the at least one pixel signal selected.

Abstract: A solid-state imaging apparatus includes a pixel circuit that outputs a pixel signal and a negative feedback circuit. The negative feedback circuit includes a sample and hold circuit (hereinafter “SH circuit”) that samples and holds the pixel signal, and a feedback amplifier that negatively feeds back, to the SH circuit, a feedback signal according to a difference between the pixel signal from the pixel circuit and an output signal from the SH circuit.

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.
