Patent ID: 8237843

Claim:
An imaging device, comprising: an imaging lens having an aperture stop; an imaging element adapted to obtain image data based on received light; and a microlens array provided in the focal plane of the imaging lens between the imaging lens and imaging element, the microlens array including a plurality of microlenses arranged in such a manner that each microlens is associated with a plurality of imaging pixels of the imaging element, wherein the arrangement of the microlenses of the microlens array is corrected from an equidistant arrangement to a non-linear arrangement according to the height of the image from the imaging lens on the imaging element; wherein the arrangement of the microlenses is corrected to the non-linear arrangement in the direction in which image height deviation appropriate to the image height cancels out; and wherein the rate of increase of a correction amount for the non-linear arrangement of the microlenses gradually diminishes with increase in the image height.
