Embodiment Construction

[0027] Embodiments of the present invention will be described with reference to the drawings. First, a VR image will be explained, and then a display control device according to the embodiment will be explained.

[0028] VR image

[0029] A VR image is an image that can be displayed in VR (displayed in the "VR view" display mode). The VR image includes an omnidirectional image (spherical image) captured by an omnidirectional camera (spherical camera), and a panoramic image whose image range (effective image range) is wider than that of an image that can be displayed on a display unit at one time. VR images are not only still images, but also moving images and live view images (images acquired from a camera in almost real time). VR images have a field of view that is maximum 360° in the vertical direction (vertical angle, angle relative to the zenith, elevation angle, depression angle, attitude angle, pitch angle) and maximum in the horizontal direction (horizontal angle, azi...

Abstract

The invention relates to an electronic device, a control method of the electronic device, and a storage medium. The electronic device comprises: an acquisition unit configured to acquire an image set including a first image and a second image which have parallax from each other; and a control unit configured to perform control such that 1) in a case of a first display mode where the first image is to be displayed without displaying the second image, the first image is displayed on a display with an orientation of the first image being corrected to be directed to be in a predetermined orientation, and 2) in a case of a second display mode where both the first image and the second image are to be displayed, the first image and the second image are displayed on the display without an orientation of the first image and the second image being corrected to be directed to be in the predetermined orientation.

Description

technical field [0001] The present invention relates to an electronic device for controlling display of VR images, a control method for the electronic device, and a storage medium. Background technique [0002] There is known a technique of displaying stereoscopic virtual reality (VR) images by acquiring wide-angle images with parallax using two optical systems and mapping and displaying the images on a virtual sphere. A dual-lens VR camera for capturing images with parallax includes two optical systems facing the same direction. Therefore, the twin-lens VR camera captures two images with parallax through one image capturing operation. As a twin-lens VR camera, in particular, a camera is known that captures images of a wide range of at least 180° (a hemisphere, 90° from the image center in all directions) vertically and horizontally in each optical system. [0003] In addition, as a VR display method, "single-lens VR display" is known, which converts a VR image to be mappe...
