Abstract
Disclosed is an image sensor including first and second pixels arranged in a first row, for outputting first and second pixel signals through first and third column lines during a unit row time; third and fourth pixels arranged in a second row, for outputting third and fourth pixel signals through second and fourth column lines during the unit row time; an alignment circuit for aligning the first to fourth pixel signals for each row, and outputting first to fourth alignment signals, according to control signals; a first signal conversion circuit for generating a first depth information signal corresponding to a difference in voltage levels between the first and second alignment signals, through one A/D conversion operation; and a second signal conversion circuit for generating a second depth information signal, corresponding to a difference in voltage levels between the third and fourth alignment signals, through one A/D conversion operation.
