Abstract
There is provided an information processing apparatus capable of determining an object area with high accuracy. An object area determination unit of the information processing apparatus acquires defocus information of positions in a captured image and information of a position specified as an object in the captured image, and determines, based on a difference between a defocus value at each of the positions and a defocus value at the specified position, an estimated area of the object specified in the captured image. Further, the object area determination unit determines an object area from the captured image based on an evaluation value calculated from each of a plurality of evaluation areas set for the specified position.
Claims13
An information processing apparatus comprising:
- a determination circuit configured to acquire defocus values at positions in a captured image, acquire a position specified as an object in the captured image, determine, based on a difference between a defocus value at each of the positions and a defocus value at the specified position, an estimated area of the object specified in the captured image, and determine an object area from the captured image based on an evaluation value calculated from each of a plurality of evaluation areas set for the specified position,
- wherein the determination circuit uses an evaluation area contained in the estimated area.
An imaging apparatus comprising:
- an image sensor configured to generate an image signal of a captured image;
- a control circuit configured to generate defocus information at positions of pixels in the captured image;
- a determination circuit configured to acquire a position specified as an object in the captured image, determine, based on a difference between a defocus value at each of the positions and a defocus value at the specified position, an estimated area of the object specified in the captured image, and determine an object area from the captured image based on an evaluation value calculated from each of a plurality of evaluation areas set for the specified position,
- wherein the determination circuit uses an evaluation area contained in the estimated area.
An information processing method comprising:
- acquiring defocus values at positions in a captured image, acquiring a position specified as an object in the captured image, and determining, based on a difference between a defocus value at each of the positions and a defocus value at the specified position, an estimated area of the object specified in the captured image;
- and
- determining an object area from the captured image based on an evaluation value calculated from each of a plurality of evaluation areas set for the specified position,
- wherein an evaluation area contained in the estimated area is used.
A non-transitory computer-readable storage medium storing a program to be executed by an information processing apparatus, the program including executable instructions for achieving an information processing method, the method comprising:
- acquiring defocus values at positions in a captured image, acquiring a position specified as an object in the captured image, and determining, based on a difference between a defocus value at each of the positions and a defocus value at the specified position, an estimated area of the object specified in the captured image;
- and
- determining an object area from the captured image based on an evaluation value calculated from each of a plurality of evaluation areas set for the specified position,
- wherein an evaluation area contained in the estimated area is used.
