Abstract

To determine a state of an object appropriate for shooting. The image capture apparatus is provided with: the image capture unit; the shooting information acquisition unit; the major object identification unit; and the positional relationship determination unit. The image capture means captures an image of an object. The shooting information acquisition unit acquires information relating to optical aberration in the image capture unit. The major object identification unit identifies the major object in the image captured by the image capture unit. A status of the major object identified by the major object identification unit is determined based on the information relating to optical aberration acquired by the positional relationship determination unit and the shooting information acquisition unit.

Claims

1. An image capture apparatus comprising:

a processor which is configured to;

capture an image of an object;

acquire information relating to optical aberration in the image capture unit;

identify a major object in an image captured by the image capture unit; and

determine a status of the major object based on the information relating to optical aberration.

2. The image capture apparatus according to claim 1, wherein the processor is configured to:

acquire information of optical distortion in a lens as the information relating to optical aberration; and

determine a position of the major object in an angle of view as the status of the major object.

3. The image capture apparatus according to claim 2, wherein the processor is configured to:

identify a region in the angle of view suffering from the optical distortion in the lens,

determine the region suffering from the optical distortion in the lens and the position of the major object.

4. The image capture apparatus according to claim 1, wherein the processor is configured to:

acquire information of distance from the major object,

determine a distance status of the major object from the image capture apparatus as the status of the major object.

5. The image capture apparatus according to claim 4, wherein the processor is configured to:

determine a dimension of the major object occupying the angle of view or a distance from the major object as the distance status of the major object from the image capture apparatus.

6. The image capture apparatus according to claim 4, wherein the processor is configured to determine that the status of the major object is preferable in the case of the major object being distant from the image capture apparatus.

7. The image capture apparatus according to claim 1, wherein the processor is configured to notify the status of the major object.

8. The image capture apparatus according to claim 1, wherein the processor is configured to assist attaining a preferable state if the status of the major object determined to be not preferable.

9. The image capture apparatus according to claim 1, wherein the processor is configured to capture the image if the status of the major object determined is preferable.

10. The image capture apparatus according to claim 1, wherein the processor is configured to identify a human face as the major object.

11. The image capture apparatus according to claim 1, wherein the processor is configured to generate a new image by performing a process of enlarging and trimming a region of the major object from the image captured by the image capture apparatus.

12. The image capture apparatus according to claim 1, wherein the processor is configured to determine a status of the major object based on the information relating to optical aberration. in the case of selfie shooting.

13. The image capture apparatus according to claim 12, wherein the processor is configured to:

acquire attitude information relating to attitude of the apparatus; and

detect the selfie shooting based on the attitude information.

14. The image capture apparatus according to claim 1, wherein the processor is configured to capture an image of the object with a wide-angle lens.

15. The image capture apparatus according to claim 1, comprising:

a first housing that has the image capture unit;

a second housing that is connected to the first housing and has a display unit; and

a third housing that is connected to the first housing.

16. A determination method performed by an image capture apparatus provided with an image capture unit that captures an image of an object, the method comprising:

acquiring information relating to optical aberration in the image capture unit;

identifying a major object from an image captured by the image capture unit; and

determining a status of the major object based on the information relating to optical aberration.

17. A non-transitory computer readable storage medium encoded with a computer-readable program that enables a computer to execute functions comprising:

acquiring information relating to optical aberration in the image capture unit;

identifying a major object from an image captured by the image capture unit; and

determining a status of the major object based on the information relating to optical aberration.
