Patent attributes
A plurality of lenses 102a to 102d arranged in the same plane form a plurality of subject images on a plurality of imaging regions 104a to 104d. Vertical line directions and horizontal line directions of the pixel arrangement in the respective plurality of imaging regions are equal to one another among the plurality of imaging regions. Further, at least one pair of subject images received by at least one pair of imaging regions having a parallax in the vertical line (or horizontal line) direction among the plurality of imaging regions are shifted from each other by a predetermined amount in the horizontal line (or vertical line) direction. By performing pixel shifting in a direction perpendicular to the direction in which a parallax is generated, it always is possible to obtain a high-resolution image even when the subject distance varies.
