Document Type and Number:
Japanese Patent JP2023132446
Kind Code:
A
Abstract:
To achieve an image-plane phase-difference autofocus function without depending on an image sensor.SOLUTION: A camera module includes: an image sensor that performs photoelectric conversion on incident light; a lens system that condenses the incident light toward the image sensor; an aperture diaphragm having an opening that allows the incident light toward the lens system to pass; and a shield device capable of shielding at least a part of the opening. The shield device changes into at least each of a first shield state where only a first light beam bundle asymmetric with respect to a main light beam of an entire light beam bundle that passes through the entire opening is allowed to pass, and a second shield state where only a second light beam bundle different from the first light beam bundle and asymmetric with respect to the main light beam is allowed to pass.SELECTED DRAWING: Figure 3
