Abstract
An image processing apparatus comprises an acquisition unit that acquires image data, an estimation unit that detects a predetermined subject from the image data and estimates posture information of the detected subject, and a determination unit that, in a case where a plurality of subjects are detected by the estimation unit, determines a main subject from the plurality of subject using feature vector of each of the subjects obtained from the posture information.
Claims15
An image processing apparatus comprising:
- an acquisition unit that acquires image data;
- an estimation unit that detects a plurality of subjects from the image data and estimates likelihood of each of the plurality of subjects being a main subject based on posture information of the detected subjects;
- and
- a determination unit that determines a main subject from the plurality of subjects based on the likelihood of the each subject estimated by the estimation unit,
- wherein each unit is implemented by one or more processors.
An image capturing apparatus comprising:
- an image processing apparatus that includes:
- an acquisition unit that acquires image data;
- an estimation unit that detects a plurality of subjects from the image data and estimates likelihood of each of the plurality of subjects being a main subject based on posture information of the detected subjects;
- and
- a determination unit that determines a main subject from the plurality of subjects based on the likelihood of the each subject estimated by the estimation unit;
- an image sensing unit that outputs the image data;
- and
- a focus adjustment unit that performs focus adjustment based on the image data within an area of the main subject determined by the determination unit,
- wherein each unit is implemented by one or more processors.
An image processing method comprising:
- acquiring image data;
- detecting a plurality of subjects from the image data and estimating likelihood of each of the plurality of subjects being a main subject based on posture information of the detected subjects;
- and
- determining a main subject from the plurality of subjects based on the likelihood of the each subject.
A non-transitory computer-readable storage medium, the storage medium storing a program that is executable by the computer, wherein the program includes program code for causing the computer to execute an image processing method, the method comprising:
- acquiring image data;
- detecting a plurality of subjects from the image data and estimating likelihood of each of the plurality of subjects being a main subject based on posture information of the detected subjects;
- and
- determining a main subject from the plurality of subjects based on the likelihood of the each subject.
