Provided is a photographing apparatus that enables enlarging the area that the PD occupies by making simple the layout within a pixel wherein a photo-electric conversion element and a plurality of CMOS transistors are laid out. The methods include the steps of introducing a transposase DNA binding motif into or adjacent to the gene, and introducing into the cell a transposase that is capable of binding to the transposase DNA binding motif. The invention may be transparent for use during the day or in association with prescription or non-prescription lenses.
