Abstract
An image pickup apparatus that is capable of suppressing degradation of image quality even when the orientation of a photographing lens is changed in a state in which a dome is attached to the image pickup apparatus. A dome attaching/detaching mechanism detachably holds a dome which is transparent and has a hemispherical shape. An image pickup unit is arranged inside the dome and is capable of changing an orientation of a lens group by a tilt mechanism. An image processor performs correction processing on an image photographed by the image pickup unit. The image processor performs image quality correction according to the orientation of the lens group.

An image pickup apparatus comprising:
- a cover member that comprises a first portion having a constant curvature, and a second portion formed continuously with the first portion and including a curved surface different in curvature from the first portion or a flat surface that is not curved;
- an image pickup unit including a photographing lens and an image pickup device, wherein the photographing lens is arranged inside the cover member, a tilt position of the photographing lens is capable of being changed by a tilt mechanism, and a focus position of the photographing lens is adjustable;
- and
- an image processing unit that performs image processing for correcting an image output from the image pickup device;
- wherein the image processing for correcting the image includes at least one of respective corrections of sharpness, gamma, saturation, aberration, and noise reduction, and
- wherein the image processing unit performs the image processing so that a correction amount of image processing in a case where a field of view of the photographing lens overlaps with the second portion of the cover member is larger than a correction amount of image processing in a case where a field of view of the photographing lens overlaps with the first portion of the cover member.
An image processing apparatus that uses an image photographed by an image pickup apparatus which includes a photographing lens and an image pickup device, wherein a tilt position of the photographing lens is changed by a tilt mechanism, a focus position of the photographing lens is adjustable, and the photographing lens is arranged inside a cover member comprising a first portion having a constant curvature, and a second portion formed continuously with the first portion and including a curved surface different in curvature from the first portion or a flat surface that is not curved, the image processing apparatus comprising:
- an image processing unit that performs image processing for correcting an image output from the image pickup device;
- wherein the image processing for correcting the image includes at least one of respective corrections of sharpness, gamma, saturation, aberration, and noise reduction, and
- wherein the image processing unit performs the image processing so that a correction amount of image processing in a case where a field of view of the photographing lens overlaps with the second portion of the cover member is larger than a correction amount of image processing in a case where a field of view of the photographing lens overlaps with the first portion of the cover member.
A method of controlling an image pickup apparatus having a cover member that comprises a first portion having a constant curvature, and a second portion formed continuously with the first portion and including a curved surface different in curvature from the first portion or a flat surface that is not curved, an image pickup unit including a photographing lens and an image pickup device, wherein the photographing lens is arranged inside the cover member, a tilt position of the photographing lens is capable of being changed by a tilt mechanism, and a focus position of the photographing lens is adjustable, the method comprising:
- an image processing step for performing image processing for correcting the image output from the image pickup device;
- the image processing for correcting the image includes at least one of respective corrections of sharpness, gamma, saturation, aberration, and noise reduction, and
- wherein the image processing is processing so that a correction amount of image processing in a case where a field of view of the photographing lens overlaps with the second portion of the cover member is larger than different a correction amount of image processing in a case where a field of view of the photographing lens overlaps with the first portion of the cover member.
A method of controlling an image processing apparatus that uses an image photographed by an image pickup apparatus which includes a photographing lens and an image pickup device, wherein a tilt position of the photographing lens is changed by a tilt mechanism, a focus position of the photographing lens is adjustable, and the photographing lens is arranged inside a cover member comprising a first portion having a constant curvature, and a second portion formed continuously with the first portion and including a curved surface different in curvature from the first portion or a flat surface that is not curved, the method comprising:
- an image processing step that performs image processing for correcting an image output from the image pickup device;
- and
- the image processing for correcting the image includes at least one of respective corrections of sharpness, gamma, saturation, aberration, and noise reduction, and
- wherein the image processing is processing so that a correction amount of image processing in a case where a field of view of the photographing lens overlaps with the second portion of the cover member is larger than a correction amount of image processing in a case where a field of view of the photographing lens overlaps with the first portion of the cover member.
A non-transitory storage medium storing a program causing a processor to execute a method of controlling an image pickup apparatus having a cover member that comprises a first portion having a constant curvature, and a second portion formed continuously with the first portion and including a curved surface different in curvature from the first portion or a flat surface that is not curved, an image pickup unit including a photographing lens and an image pickup device, wherein the photographing lens is arranged inside the cover member, a tilt position of the photographing lens is capable of being changed by a tilt mechanism, and a focus position of the photographing lens is adjustable, the method comprising:
- an image processing step for performing image processing for correcting an image output from the image pickup device;
- and
- wherein the image processing for correcting the image includes at least one of respective corrections of sharpness, gamma, saturation, aberration, and noise reduction, and
- wherein the image processing is performed so that a correction amount of image processing in a case where a field of view of the photographing lens overlaps with the second portion of the cover member is larger than a correction amount of image processing in a case where a field of view of the photographing lens overlaps with the first portion of the cover member.
A non-transitory storage medium storing a program causing a processor to execute a method of controlling an image processing apparatus that uses an image photographed by an image pickup apparatus which includes a photographing lens and an image pickup device, wherein a tilt position of the photographing lens is changed by a tilt mechanism, a focus position of the photographing lens is adjustable, and the photographing lens is arranged inside a cover member comprising a first portion having a constant curvature, and a second portion formed continuously with the first portion and including a curved surface different in curvature from the first portion or a flat surface that is not curved, the method comprising:
- an image processing step for performingimage processing for correcting an image output from the image pickup device ;
- wherein the image processing for correcting the image includes at least one of respective corrections of sharpness, gamma, saturation, aberration, and noise reduction, and
- wherein the image processing is performed so that a correction amount of image is performed processing in a case where a field of view of the photographing lens overlaps with the second portion of the cover member is larger than a correction amount of image processing in a case where a field of view of the photographing lens overlaps with the first portion of the cover member.
