Abstract
An image pickup apparatus that prevents erroneous recognition of a photographing range when a video acquired using an anamorphic lens is displayed. A system controller determines a type of a lens mounted on a lens mounting section. When the type of the mounted lens is a first lens for scaling a video by a factor of 1/a in a horizontal direction, first aspect markers indicating an aspect ratio of M:N are displayed in a state superimposed on a first video acquired via the first lens. When the type of the mounted lens is a second lens for scaling the video by a factor of 1/b in the horizontal direction, second aspect markers indicating an aspect ratio of M′:N (M′=M×a/b) are displayed in a state superimposed on a second video acquired via the second lens.
Claims15
An image pickup apparatus comprising:
- a lens mounting section;
- a determination unit configured to determine a type of a lens mounted on the lens mounting section;
- and
- a display control unit configured to perform control such that in a case where it is determined by the determination unit that the type of the lens mounted on the lens mounting section is a first lens for scaling a video by a factor of 1/a (a≥1) in a horizontal direction with respect to a vertical direction, first aspect markers indicating an aspect ratio of M:N are displayed in a state superimposed on a first video acquired via the first lens, whereas in a case where it is determined by the determination unit that the type of the lens mounted on the lens mounting section is a second lens for scaling the video by a factor of 1/b (b≥1, a≠b) in the horizontal direction with respect to the vertical direction, second aspect markers indicating an aspect ratio of M′:N (M′=M×a/b) are displayed in a state superimposed on a second video acquired via the second lens.
An image pickup apparatus comprising:
- a lens mounting section that is capable of having mounted thereon a first lens for reducing a video by a factor of 1/a (a>1) in a horizontal direction with respect to a vertical direction;
- a transformation unit configured to generate a first transformed video by enlarging a first video acquired via the first lens by a factor of a in the horizontal direction;
- a display unit configured to display a video;
- and
- a display control unit configured to perform control such that in a case where the first transformed video generated by the transformation unit is displayed, first aspect markers indicating an aspect ratio of m:n are displayed in a state superimposed on the first transformed video, whereas in a case where the first video is displayed, second aspect markers indicating an aspect ratio of m/a:n are displayed in a state superimposed on the first video.
A non-transitory computer-readable storage medium storing a computer-executable program for executing a display control method for displaying a video acquired by an image pickup apparatus including a lens mounting section via a lens mounted on the lens mounting section,
- wherein the display control method comprises:
- determining a type of the lens mounted on the lens mounting section;
- and
- performing control such that in a case where it is determined that the type of the lens mounted on the lens mounting section is a first lens for scaling a video by a factor of 1/a (a≥1) in a horizontal direction with respect to a vertical direction, first aspect markers indicating an aspect ratio of M:N are displayed in a state superimposed on a first video acquired via the first lens, whereas in a case where it is determined that the type of the lens mounted on the lens mounting section is a second lens for scaling the video by a factor of 1/b (b≥1, a≠b) in the horizontal direction with respect to the vertical direction, second aspect markers indicating an aspect ratio of M′:N (M′=M×a/b) are displayed in a state superimposed on a second video acquired via the second lens.
A non-transitory computer-readable storage medium storing a computer-executable program for executing a display control method for displaying a video acquired by an image pickup apparatus on which a first lens for reducing a video by a factor of 1/a (a>1) in a horizontal direction with respect to a vertical direction is mounted,
- wherein the display control method comprises:
- generating a first transformed video by enlarging a first video acquired by the image pickup apparatus via the first lens by a factor of a in the horizontal direction;
- and
- performing control such that in a case where the first transformed video is displayed, first aspect markers indicating an aspect ratio of m:n are displayed in a state superimposed on the first transformed video, whereas in a case where the first video is displayed, second aspect markers indicating an aspect ratio of m/k:n are displayed in a state superimposed on the first video.
