Abstract
The present disclosure proposes a solution in which an electronic device configures at least one view window existing in an image frame including a plurality of post-processing areas, identifies a plurality of division areas obtained by dividing the configured view window by the plurality of post-processing areas, obtains a compensation parameter on the basis of the plurality of identified division areas, and processes an image in the view window using the obtained compensation parameter.

A method for processing an image frame for a virtual reality content in an electronic device, comprising:
- setting a view window in an image frame corresponding to a 360 degree image, the image frame including a plurality of first areas;
- identifying at least one second area in an image which is a part of the image frame within the view window, wherein each of the at least one second area corresponds to a part of an area among the plurality of first areas, and the part of the area among the plurality of areas is within the view window;
- obtaining at least one compensation parameter based on the at least one second area;
- and
- processing the image within the view window using the obtained at least one compensation parameter,
- wherein the at least one compensation parameter is based on at least one parameter set for each of the at least one second areas and a ratio of a size of each of the at least one second areas with respect to a size of the view window.
An electronic device for processing an image frame for a virtual reality content, comprising:
- a controller configured to:
- set a view window in an image frame corresponding to a 360 degree image, the image frame including a plurality of first areas,
- identify at least one second area in an image which is a part of the image frame within the view window, wherein the at least one second area corresponds to a part of an area among the plurality of first areas, and the part of the area among the plurality of areas is within the view window,
- obtain at least one compensation parameter based on the at least one second area, and
- process the image within the view window using the obtained at least one compensation parameter;
- and
- a display unit configured to display the processed image,
- wherein the at least one compensation parameter is based on at least one parameter set for each of the at least one second area and a ratio of a size of each of the at least one second area with respect to a size of the view window.
