Abstract
The imaging device includes an image sensor that has a plurality of phase difference pixels and outputs phase difference information and a captured image, and at least one processor, in which the processor is configured to acquire subject distance information indicating a distance to a subject existing in a focusing target region and peripheral distance information indicating a distance to an object existing in a peripheral region of the focusing target region based on the phase difference information.
Claims16
An imaging device comprising:
- an image sensor that has a plurality of first phase difference pixels and a plurality of second phase difference pixels, and outputs a captured image;
- and
- at least one processor,
- wherein the at least one processor is configured to:
- convert signals obtained from the plurality of first phase difference pixels and the plurality of seconds phase difference pixels into first phase difference information and second phase difference information by using a local binary encoding method;
- acquire distance distribution information corresponding to the captured image by performing a shift operation on the first phase difference information on the second phase difference information;
- and
- acquire subject distance information indicating a distance to a subject existing in a focusing target region and peripheral distance information indicating a distance to an object existing in a peripheral region of the focusing target region based on the distance distribution information.
A method of driving an imaging device including an image sensor that has a plurality of first phase difference pixels and a plurality of second phase difference pixels, and outputs a captured image, the method comprising:
- converting signals obtained from the plurality of first phase difference pixels and the plurality of seconds phase difference pixels into first phase difference information and second phase difference information by using a local binary encoding method;
- acquiring distance distribution information corresponding to the captured image by performing a shift operation on the first phase difference information on the second phase difference information;
- and
- acquiring subject distance information indicating a distance to a subject existing in a focusing target region and peripheral distance information indicating a distance to an object existing in a peripheral region of the focusing target region based on the distance distribution information.
A non-transitory computer-readable storage medium storing a program that operates an imaging device including an image sensor that has a plurality of first phase difference pixels and a plurality of second phase difference pixels, and outputs a captured image, the program causing the imaging device to perform processing of:
- converting signals obtained from the plurality of first phase difference pixels and the plurality of seconds phase difference pixels into first phase difference information and second phase difference information by using a local binary encoding method;
- acquiring distance distribution information corresponding to the captured image by performing a shift operation on the first phase difference information on the second phase difference information;
- and
- acquiring subject distance information indicating a distance to a subject existing in a focusing target region and peripheral distance information indicating a distance to an object existing in a peripheral region of the focusing target region based on the distance distribution information.
