摘要： A method of correcting image latency in implementing augmented reality includes receiving a first image including frames, in which a time point and a pose of an electronic apparatus for each frame are recorded, from an external apparatus; rendering the first image; receiving first data corresponding to a first time point of a first frame; receiving second data corresponding to a second time point of a second frame; calculating a respective pose of the electronic apparatus for each scan line of a second image based on the first data and the second data; calculating a pixel shift for each pixel in each scan line based on the respective pose calculated for each scan line; generating the second image by correcting the first image based on the pixel shift; and transmitting the second image to the external apparatus.
