Abstract
A signal processing device, on the basis of an image capture signal acquired by an image capture device provided with an anamorphic lens, performs a detection process each in a vertical direction of the anamorphic lens and in a horizontal direction of the anamorphic lens.
Claims20
A signal processing device, comprising:
- the signal processing device configured to:
- perform, based on an image capture signal acquired by an image capture device with an anamorphic lens, a detection process in each of a vertical direction of the anamorphic lens and a horizontal direction of the anamorphic lens;
- acquire, based on the detection process, detection information in each of the vertical direction of the anamorphic lens and the horizontal direction of the anamorphic lens;
- and
- determine an in-focus position of a subject based on the acquired detection information.
A signal processing method, comprising:
- performing, based on an image capture signal acquired by an image capture device with an anamorphic lens, a detection process in each of a vertical direction of the anamorphic lens and a horizontal direction of the anamorphic lens;
- acquiring, based on the detection process, detection information in each of the vertical direction of the anamorphic lens and the horizontal direction of the anamorphic lens;
- and
- determining an in-focus position of a subject based on the acquired detection information.
A non-transitory computer-readable medium having stored thereon, computer-executable instructions which, when executed by a computer, cause the computer to execute operations, the operations comprising:
- performing, based on an image capture signal acquired by an image capture device with an anamorphic lens, a detection process in each of a vertical direction of the anamorphic lens and in a horizontal direction of the anamorphic lens;
- acquiring, based on the detection process, detection information in each of the vertical direction of the anamorphic lens and the horizontal direction of the anamorphic lens;
- and
- determining an in-focus position of a subject based on the acquired detection information.
An image capture device, comprising:
- an anamorphic lens;
- an image capture element that includes a plurality of phase difference detection pixels to make placement densities different between a vertical direction of the anamorphic lens and a horizontal direction of the anamorphic lens, wherein the horizontal direction is orthogonal to the vertical direction;
- and
- a signal processing unit configured to:
- perform, based on an image capture signal acquired by the image capture element, a detection process in each of the vertical direction of the anamorphic lens and the horizontal direction of the anamorphic lens;
- acquire, based on the detection process, detection information in each of the vertical direction of the anamorphic lens and the horizontal direction of the anamorphic lens;
- and
- determine an in-focus position of a subject based on the acquired detection information.
