US Patent 10101452 Distance measuring device

In a distance measuring device, a pixel G includes sub pixels Po and Pe in a row direction. Floating diffusion parts Fd1 to Fd4 detect charge quantities relating to reflected modulated light Lb in four terms which are delayed in start by every ¼ of a period of emitted modulated light La in order. A binning group Gv is configured by an array part that the two sub pixels Po and the two sub pixels Pe are adjacent to each other in a row direction.
