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.

Provided is an image transmission method. Left-eye image data and right-eye image data corresponding to a same original image frame in a target video are divided into sub-images on the image processing device side, multiple sets of image data in one-to-one correspondence with the sub-images are generated, and transmitted to the image display device through transmission threads. Each of the multiple sets of image data includes a sub-image, and first and second sequence numbers that correspond to the sub-image. Left-eye image data and right-eye image data corresponding to a same original image frame are obtained by combining sub-images in the multiple sets of image data, by the image display device, based on first and second sequence numbers in the multiple sets of image data. Finally, a left-eye image corresponding to the left-eye image data and a right-eye image corresponding to the right-eye image data are played.
