A photogate electrode PG has a planar shape of a rectangular shape having first and second long sides LS1, LS2 opposed to each other and first and second short sides SS1, SS2 opposed to each other. First and second semiconductor regions FD1, FD2 are arrang...

The range image sensor is a range image sensor which is provided on a semiconductor substrate with an imaging region composed of a plurality of two-dimensionally arranged units (pixel P), thereby obtaining a range image on the basis of charge quantities Q ...

A signal current I1 that is output from output terminal of semiconductor position detection element is converted to a signal voltage V1 by a current/voltage conversion unit and a signal current I2 that is output from output terminal is converted to a signa...
