1. A method of generating at least a first panoramic picture and a second panoramic picture based on a series of frames acquired by one frame acquisition device while said device is panned in a main direction, a global motion value and a perspective transform being computed for each pair of consecutive frames of the series, said global motion value reflecting a displacement in the main direction between the frames of a pair of frames and said perspective transform reflecting a perspective change between the frames of a pair of frames;

  • wherein for each frame of the series, a first area of the frame is determined for the first panoramic picture and a second area of the frame, distinct from the first area, is determined for the second panoramic picture,wherein the method further comprises, upon acquisition of a current frame of the series of frames;

    determining a first frame among the already acquired frames of the series of frames, which has a second area that shares at least a common area with the first area of the current frame;

    calculating a global transform based on the perspective transforms of the pairs of consecutive frames that have been acquired between the first frame and the current frame; and

    determining an adapted first area by applying an inverse of the global transform to the first area of the current frame, said adapted first area being included into the first panoramic picture and the second area of the current frame being included into the second panoramic picture.
