We have been developing a lensless camera using a Fresnel zone aperture. This technology enables a very thin device making close-up photography possible. However, for objects with significant brightness edges, an artifact arises at fixed positions in the images. We analyze the unusual point spread function of the lensless camera and establish a method to reduce the artifact taking its uniqueness into account. |
