An electronic device according to the present invention includes: a processor; and a memory storing a program which, when executed by the processor, causes the electronic device to: perform control to change a display region of an image in accordance with an orientation change of the electronic device or in accordance with accepting a user operation and display the display region of the image on a screen; and determine a clipping region of the image to be clipped from the image based on a position of the display region of the image, wherein the image includes the display region and the clipping region and the clipping region is wider than the display region.

Various embodiments describe systems and processes for capturing and generating multi-view interactive digital media representations (MIDMRs). In one aspect, a method for automatically generating a MIDMR comprises obtaining a first MIDMR and a second MIDMR. The first MIDMR includes a convex or concave motion capture using a recording device and is a general object MIDMR. The second MIDMR is a specific feature MIDMR. The first and second MIDMRs may be obtained using different capture motions. A third MIDMR is generated from the first and second MIDMRs, and is a combined embedded MIDMR. The combined embedded MIDMR may comprise the second MIDMR being embedded in the first MIDMR, forming an embedded second MIDMR. The third MIDMR may include a general view in which the first MIDMR is displayed for interactive viewing by a user on a user device. The embedded second MIDMR may not be viewable in the general view.

A method for realizing 3D image display is provided. The method comprises: detecting a posture change of a 3D display device; and adjusting a displayed image to a display dimension different from a display dimension before the posture of the 3D display device changes when detecting that a posture of the 3D display device changes, and adjusting a display orientation of the displayed image, so that the display orientation of the displayed image is kept in an initial display orientation before the posture change of the 3D display device. The solution solves a problem that an electronic device cannot display a suitable picture after posture adjustment. A 3D display device, a computer-readable storage medium, and a computer program product are also provided.

A 3D display device is provided, comprising: a multi-viewpoint 3D display screen, comprising a plurality of composite pixels, wherein each composite pixel in the plurality of composite pixels comprises a plurality of composite subpixels, and each composite subpixel in the plurality of composite subpixels comprises a plurality of subpixels corresponding to a plurality of viewpoints; an eye positioning apparatus, configured to acquire spatial positions of eyes of a user; and a 3D processing apparatus, configured to determine the viewpoints by the spatial positions of the eyes of the user, and render the subpixels, corresponding to the viewpoints, in the plurality of composite subpixels based on received 3D signals. According to the above 3D display device, the flexibility of 3D display can be improved. A 3D display method, a 3D display terminal, a computer-readable storage medium and a computer program product are also provided.

An electronic device includes an image sensor, a projector, an adjustable mount, a processor, and a memory. The memory stores instructions executable by the processor to: receive at least one image of an environment around the electronic device from the image sensor; determine a face pose of a viewer based on the at least one image; determine characteristics of a projection surface based on the at least one image; control the projector to project a plurality of images onto the projection surface, the images determined based in part on the face pose of the viewer and the characteristics of the projection surface, wherein the images are configured to be perceived as a three-dimensional (3D) object image when viewed through 3D glasses; and control the adjustable mount to adjust a position or an orientation of the projector based in part on a change in the face pose of the viewer.

A three-dimensional display device includes a display panel, an optical panel, and a controller. The display panel displays a parallax image. The optical panel defines a traveling direction of image light. The controller controls the parallax image based on positions of a first eye and a second eye of a user. The controller causes a predetermined proportion of pixels to display a black image. The predetermined proportion is determined to cause, for the first and second eyes of the user at a predetermined reference position, a black image to be displayed by a pixel at one end or two ends of multiple first areas viewable to the first eye and not viewable to the second eye and by a pixel at one end or two ends of multiple second areas viewable to the second eye and not viewable to the first eye in a parallax direction.
