Abstract:
In order to produce, for example, an image sensing module which has a resolving power enough to meet required specifications for both photographing a close object and photograph a far object, and which has a simple structure, an image sensing module includes: an imaging lens having an increased depth of field and a decreased curvature of field; and a sensor provided between (i) a location of a best image surface of the imaging lens with respect to white light from a sunflower and (ii) a location of a best image surface of the imaging lens with respect to white light from a tree.
