Abstract: A supersampling method includes generating a current rendered image frame by performing jittered sampling on a three-dimensional (3D) scene, based on sub-pixels of low-resolution pixels for the current rendered image frame; generating a current warped image frame by warping a previous output image frame, based on a motion vector map corresponding to a difference between the current rendered image frame and a previous rendered image frame; generating a current shifted image frame by shifting pixels of the current warped image frame, based on a change in sampling positions based on the jittered sampling; and generating a current output image frame, based on the current rendered image frame and the current shifted image frame.

Abstract: Provided are a tomography image generating method and an apparatus for generating a tomography image. The method of generating a tomography image includes, in response to a depth scan operation performed on an object, generating a candidate tomography image by using an interference signal acquired by the performed depth scan operation, determining a pixel pattern by using the generated candidate tomography image; and when the depth scan operation performed on the object is completed, generating a final tomography image of the object by using a finally determined pixel pattern. The generating the candidate tomography image and the determining are parallel processed by at least one processor during the depth scan operation being repeatedly performed.
