The present disclosure relates to a camera module capable of achieving a smaller height, a method of manufacturing a camera module, an imaging apparatus, and an electronic apparatus. An imaging device having its imaging surface bonded to a provisional substrate is attached, and the imaging device in that state is joined to a substrate via an electrode having a TSV structure. After the provisional substrate is detached, an IR cut filter (IRCF) on which a light blocking film is printed or jet-dispensed in a region other than the effective pixel region is bonded to the imaging surface via a transparent resin. Because of this, there is no need to provide any sealing glass in the stage before the imaging surface, and the optical length of the lens can be shortened. Thus, a smaller height can be achieved. The present disclosure can be applied to camera modules.

Techniques are described for dynamically correcting image distortion during imaging of a patterned sample having repeating spots.
