Abstract
An apparatus includes an acquisition unit configured to acquire distance information that indicates a distance to a subject on each predetermined region in a captured image, a control unit configured to adjust a focus position, and a storage unit configured to store first distance information acquired by the acquisition unit in response to the adjusted focus position. The control unit readjusts the focus position based on the first distance information and second distance information acquired by the acquisition unit.
Claims20
An apparatus comprising:
- at least one processor;
- and
- a memory coupled to the at least one processor, the memory having instructions that, when executed by the processor, perform operations as:
- a control unit configured to adjust a focus position;
- an acquisition unit configured to acquire first distance information that indicates a distance to a subject on each of a plurality of regions within a predetermined region in a captured image, in a state where the focus positon is adjusted by the control unit;
- and
- a storage unit configured to store the first distance information acquired by the acquisition unit,
- wherein the acquisition unit is configured to acquire second distance information that indicates a distance to a subject on each of the plurality of regions within the predetermined region in a captured image, after the first distance information is stored,
- wherein the control unit adjusts the focus position so that a degree of matching between the first distance information and second distance information becomes higher, and
- wherein the control unit adjusts the focus position to maximize the degree of matching.
A method for controlling an apparatus comprising:
- adjusting a focus position;
- acquiring first distance information that indicates a distance to a subject on each of a plurality of regions within a predetermined region in a captured image, in a state where the focus positon is adjusted;
- storing the first distance information into a storage unit;
- acquiring second distance information that indicates a distance to a subject on each of a plurality of regions within the predetermined region in a captured image, after the first distance information is stored;
- and
- adjusting the focus position so that a degree of matching between the stored first distance information and second distance information,
- wherein the adjusting adjusts the focus position to maximize the degree of matching.
A non-transitory computer-readable medium storing a program for causing a computer to execute a method for controlling an apparatus, the method comprising:
- adjusting a focus position;
- acquiring first distance information that indicates a distance to a subject on each of a plurality of regions within a predetermined region in a captured image, in a state where the focus positon is adjusted;
- storing the first distance information into a storage unit;
- acquiring second distance information that indicates a distance to a subject on each of a plurality of regions within the predetermined region in a captured image, after the first distance information is stored;
- and
- adjusting the focus position so that a degree of matching between the stored first distance information and second distance information becomes higher,
- wherein the adjusting adjusts the focus position to maximize the degree of matching.
