Patent ID: 8605198

Claim:
An imaging device for an imaging apparatus adapted to image an object through an image formation lens, comprising: a light receiving section having a plurality of light receiving elements; a microlens section having a plurality of microlenses respectively provided corresponding to a plurality of the light receiving elements to make the corresponding light receiving elements receive an object light beam that passed through the image formation lens; a control section adapted to control shapes of the plurality of the microlenses so as to control pupil regions in an exit pupil of the image formation lens that pass a light beam that should be received by each of the plurality of the light receiving elements; and an image signal generation section adapted to generate an image signal of an image of the object based on imaging signals of the plurality of the light receiving elements, wherein the control section controls the shapes of the microlenses to be changed from a shape having first refractive power to a shape having second refractive power that is larger than the first refractive power so as to limit sizes of the pupil regions that pass the light beam that should be received by the plurality of the light receiving elements, and the imaging device further comprising a deflection section having a plurality of first deflection optical elements, the first deflection optical elements being provided respectively corresponding to a plurality of first light receiving elements, out of the plurality of the light receiving elements, to make the corresponding first light receiving elements receive, via the corresponding microlenses, an object light beam that passed through a first pupil region in the exit pupil when the plurality of the microlenses are controlled to be in the shape having the second refractive power.
