Abstract
A processor-implemented imaging method includes: obtaining initial homography information between a plurality of tele images that covers a field of view (FOV) of a wide image; receiving a user input of zooming a partial region of the wide image from a screen on which the wide image is displayed; stitching tele images corresponding to the partial region using the initial homography information, based on whether a zoom level corresponding to the user input exceeds a maximum zoom level of the wide image; and rendering the stitched tele images and displaying an image obtained by the rendering on the screen.
Claims16
A method of displaying an image, comprising:
- obtaining initial homography information between a plurality of tele images that covers a field of view (FOV) of a wide image;
- determining whether a user input of zooming a partial region of the wide image from a screen on which the wide image is displayed exceeds a maximum zoom level;
- in response to the zoom exceeding the maximum zoom level, determining whether a number of the tele images corresponding to the partial region is more than one tele image;
- in response to the number of the tele images corresponding to the partial region being more than one tele image, stitching tele images corresponding to the partial region using the initial homography information;
- and
- rendering the stitched tele images and displaying an image obtained by the rendering on the screen,
- wherein the stitching comprises aligning the multiple tele images corresponding to the partial region based on the initial homography information and removing an artifact occurring in a boundary region of an overlapping region among the tele images by:
- determining a deformation field of the boundary region of the tele images by an optical flow of the boundary region;
- and
- warping pixels in the boundary region based on the deformation field.
