Abstract: A computer-implemented method of (800) and an electronic device (208) for rendering a panorama image comprising a first image tile (310) and a second image tile (308). The method (800) comprises receiving the first image tile; generating, by a processor (110, 111), a first intermediate rendering result (404) by associating the first image tile (310) with a first transparent layer (410); and storing, in a non-transitory computer-readable medium (120, 130), the first intermediate rendering result (404). Upon receiving an instruction to render at least a portion of the panorama image, the method may execute accessing the first intermediate rendering result (404) and a second intermediate rendering result (414); merging the first intermediate rendering result (404) and the second intermediate rendering result (414) to render the portion of the panorama image; and displaying, on a display screen (142), the portion of the panorama image.
