Abstract
An image processing apparatus comprises a selection unit that selects an object to be detected; an acquisition unit that acquires an image; a detection unit that detects the object selected by the selection unit from the image; and a determination unit that determines a size of the object detected by the detection unit in the image, wherein the determination unit changes part of the object to be determined as the size of the object in the image in accordance with a shape of the object.
Claims14
An image processing apparatus comprising one or more processors and/or circuitry which function as:
- a selection unit that selects an object to be detected;
- an acquisition unit that acquires an image;
- a detection unit that detects the object selected by the selection unit from the image;
- and
- a determination unit that determines a size of the object detected by the detection unit in the image,
- wherein the determination unit changes part of the object to be determined as the size of the object in the image in accordance with a shape of the object.
An image capturing apparatus comprising:
- an image processing apparatus comprising one or more processors and/or circuitry which function as:
- a selection unit that selects an object to be detected;
- an acquisition unit that acquires an image;
- a detection unit that detects the object selected by the selection unit from the image;
- and
- a determination unit that determines a size of the object detected by the detection unit in the image;
- and
- an image sensor that captures an image,
- wherein the determination unit changes part of the object to be determined as the size of the object in the image in accordance with a shape of the object, and
- the acquisition unit acquires the image captured by the image sensor.
An image capturing apparatus comprising:
- an image processing apparatus comprising one or more processors and/or circuitry which function as:
- a selection unit that selects an object to be detected;
- an acquisition unit that acquires an image;
- a detection unit that detects the object selected by the selection unit from the image and a position of the detected object in the image;
- a determination unit that determines a size of the object detected by the detection unit in the image;
- and
- a subject detection unit that detects a predetermined subject included in the image and obtains the position and size of the detected subject in the image, and
- a decision unit that decides, in a case where a plurality of the subjects are detected by the subject detection unit, a main subject from the plurality of subjects based on the position and size of each of the subjects in the image and the position and size of the object in the image;
- and
- a focus control unit that performs focus control so as to focus on the main subject decided by the decision unit,
- wherein the determination unit changes part of the object to be determined as the size of the object in the image in accordance with a shape of the object.
An object size determination method comprising:
- selecting an object to be detected;
- acquiring an image;
- detecting the selected object from the image;
- and
- determining a size of the detected object in the image,
- wherein part of the object to be determined as the size of the object in the image is changed in accordance with a shape of the object.
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 function as an image processing apparatus comprising:
- a selection unit that selects an object to be detected;
- an acquisition unit that acquires an image;
- a detection unit that detects the object selected by the selection unit from the image;
- and
- a determination unit that determines a size of the object detected by the detection unit in the image,
- wherein the determination unit changes part of the object to be determined as the size of the object in the image in accordance with a shape of the object.
