Abstract
A method, performed by a device, of processing an image, may include obtaining a circular image generated by photographing a target space through a fisheye lens; generating metadata including lens shading compensation information for correcting color information of the obtained circular image; and transmitting the obtained circular image and the metadata to a terminal.
Claims8
A method of processing an image by an electronic device, the method comprising:
- obtaining a plurality of circular images via at least one fisheye lens;
- obtaining fisheye information including lens shading compensation information, wherein the lens shading compensation information includes coefficients of a polynomial function for each of RGB colors of the plurality of circular images and a number of the coefficients;
- and
- transmitting the obtained plurality of circular images and the lens shading compensation information toward another electronic device,
- wherein the polynomial function represents relation between lens shading compensation values for the plurality of circular images and a distance from a center of an image of the plurality of circular images,
- wherein the polynomial function is w=Σi=1Npi-1·ri-1, where w is a lens shading compensation value for one of the RGB colors, N is the number of the coefficients, pi-1 is a coefficient and r is the distance from the center of the image, and
- wherein compensating the plurality of circular images is performed in the another electronic device by using the lens shading compensation values.
A system comprising an electronic device of processing an image and another electronic device, the electronic device comprising:
- a communicator;
- a memory for storing instructions;
- and
- at least one processor configured to execute the stored instructions to at least:
- obtain a plurality of circular images, wherein the plurality of circular images are captured via at least one fisheye lens;
- obtain fisheye information including lens shading compensation information, wherein the lens shading compensation information includes coefficients of a polynomial function for each of RGB colors of the plurality of circular images and a number of the coefficients;
- and
- transmit, via the communicator, the obtained plurality of circular images and the lens shading compensation information toward the another electronic device,
- wherein the polynomial function represents relation between lens shading compensation values for the plurality of circular images and a distance from a center of an image of the plurality of circular images,
- wherein the polynomial function is w=Σi=1Npi-1·ri-1, where w is a lens shading compensation value for one of the RGB colors, N is the number of the coefficients, pi-1 is a coefficient and r is the distance from the center of the image, and
- wherein the another electronic device performs compensating the plurality of circular images by using the lens shading compensation values.
