Abstract
A method and an apparatus for providing panoramic image data by reconstructing frame images captured by a panoramic imaging apparatus, are disclosed. In reconstruction of images with multiple image layers, sizes of images reconstructed with an image layer or images to be used for a reconstruction are scaled. An image is selected by analyzing sharpness. A panoramic image is provided by combining selected image. According to the present invention, parts having unclear focal planes may be completely removed in a panoramic image and it is possible to provide an image including only with focused regions.
Claims9
A method for providing a panoramic image, by an apparatus including at least one memory configured to store image data, at least one processor configured to perform operations for providing a panoramic image using the stored image data and a communication circuit configured to communicate with other entities through a communication network, the method comprising:
- (a) scaling sizes of images reconstructed with an image layer or images to be used for a reconstruction in consideration of a size of a predetermined reference image according to a reference image layer;
- (b) dividing the scaled images into a plurality of blocks;
- (c) selecting clear blocks among the divided blocks representing a predetermined region of interest clearly among scaled images;
- and
- (d) providing a panoramic image with the selected clear blocks,
- wherein the divided blocks have specific regions in blocks overlapped with other block, and the clear blocks are selected with respect to the overlapped blocks.
