Abstract
A multi-layered solid state image sensor senses a three-dimensional optical image introduced through a lens having a constant focal length and a constant focal depth. The image sensor has a plurality of transparent layers stacked together with reflection preventive coating films sandwiched therebetween. A cell matrix is provided on each of the transparent layers. Cells included in each cell matrix are arranged so as not to overlap each other so that image light can effectively reach the lowermost layer. The cell matrices defining imaging surfaces on the stacked transparent layers become operative simultaneously for image sensing. Therefore, just-focused image planes at different focal points are formed on the cell matrices.
