Image sensor comprising plural pixels including a microlens and plural photoelectric conversion portions and image pickup apparatus comprising same

摘要

The image sensor 107 includes plural pixels each including a microlens and plural photoelectric conversion portions separated from one another with a separating zone thereamong and photoelectrically converting light fluxes passing through the microlens. The microlens includes a separating zone side lens portion overlapping the separating zone in an optical axis direction of the microlens. When the photoelectric conversion portions photoelectrically convert the light fluxes passing through mutually different areas of an exit pupil of an image capturing optical system, the separating zone side lens portion provides no power or a negative power for a light flux entering the separating zone side lens portion in the light fluxes entering the microlens.

1. An image sensor comprising:
plural pixels each including (a) a microlens and (b) plural photoelectric conversion portions separated from one another with a separating zone thereamong and photoelectrically converting light fluxes passing through the microlens, wherein the microlens includes a separating zone side lens portion overlapping the separating zone in an optical axis direction of the microlens, and wherein, when the photoelectric conversion portions photoelectrically convert the light fluxes passing through mutually different partial pupil areas an image optical system, the separating zone side lens portion provides no power or a negative power for a light flux entering the separating zone side lens portion so that the light flux entering the separating zone side lens portion does not enter the separating zone.
