Electronic apparatus, control method of electronic apparatus, and non-transitory computer readable medium
An electronic apparatus according to the present invention includes a processor, and a memory soring a program which, when executed by the processor, causes the electronic apparatus to execute acquisition processing to acquire a live view image, and execute display control processing to perform geometric transformation for a display range, which is a partial region of the live view image, and to perform control so as to display a geometrically transformed image for display, where the display range is changeable, wherein in the display control processing, control is performed so as to further display an item which makes the region displayed in the live view image identifiable.
1 . An electronic apparatus comprising:
a processor; and
a memory storing a program which, when executed by the processor, causes the electronic apparatus to:
execute acquisition processing to acquire a live view image, and
execute display control processing to perform geometric transformation for a display range, which is a partial region of the live view image, and to perform control so as to display a geometrically transformed image for display, where the display range is changeable, wherein
in the display control processing, control is performed so as to further display an item which makes a displayed region including a region displayed before the display range is changed in the live view image and a region displayed by changing the display range in the live view image identifiable.
2 . The electronic apparatus according to claim 1 , wherein
the item includes a reduced image generated by reducing the live image, and is an item to make a region corresponding to the displayed region in the reduced image identifiable.
3 . The electronic apparatus according to claim 1 , wherein
in the display control processing, the item is initialized in a case where a predetermined condition is satisfied.
4 . The electronic apparatus according to claim 3 , wherein
the predetermined condition is one in which an imaging position of the live view image is changed.
5 . The electronic apparatus according to claim 3 , wherein
the predetermined condition is one in which an imaging direction of the live view image is changed.
6 . The electronic apparatus according to claim 3 , wherein
the predetermined condition is one in which an imaging parameter is changed.
7 . The electronic apparatus according to claim 6 , wherein
the imaging parameter includes at least one of ISO sensitivity, an aperture value, shutter speed, white balance setting, focus setting and zoom setting.
8 . The electronic apparatus according to claim 1 , wherein
the live view image includes a plurality of image regions which are captured through a plurality of optical systems respectively, and
in the display control processing, the control is performed so as to display a part of at least one of the plurality of image regions as a display range.
9 . The electronic apparatus according to claim 8 , wherein
in the display control processing, control is performed so as to further display a second item to indicate an image region of the plurality of image regions, of which a part is displayed as the display range.
10 . The electronic apparatus according to claim 8 , wherein
each of the plurality of image regions is a region of a circular fisheye image.
11 . The electronic apparatus according to claim 1 , wherein
the geometric transformation is perspective projection transformation.
12 . The electronic apparatus according to claim 1 , wherein
the live view image is an omnidirectional image or a hemispherical image.
13 . The electronic apparatus according to claim 1 , wherein
in the display control processing, the display range is automatically changed.
14 . The electronic apparatus according to claim 1 , wherein
the live view image includes two image region having parallax with each other, and
in a case where both of the two image regions are displayed as geometrically transformed images for display, in the display control processing, control is performed so as to display, for each of the two image regions, the item which makes the displayed region identifiable.
15 . The electronic apparatus according to claim 1 , wherein
by the item, a region that has been subjected to the geometric transformation and a region that has not been subjected to the geometric transformation are made identifiable.
16 . A control method of an electronic apparatus, comprising:
acquiring a live view image;
performing geometric transformation for a display range, which is a partial region of the live view image, where the display range is changeable;
performing control so as to display a geometrically transformed image for display; and
performing control so as to further display an item which makes a displayed region including a region displayed before the display range is changed in the live view image and a region displayed by changing the display range in the live view image identifiable.
17 . A non-transitory computer readable medium that stores a program, wherein the program causes a computer to execute a control method of an electronic apparatus, the control method comprising:
acquiring a live view image;
performing geometric transformation for a display range, which is a partial region of the live view image, where the display range is changeable;
performing control so as to display a geometrically transformed image for display; and
