1. A method, comprising:
receiving a first image frame associated with a first time and a second image frame associated with a second time, wherein the second time is earlier than the first time; and
determining a third image frame that includes a first plurality of pixels and a second plurality of pixels, wherein the first plurality of pixels and the second plurality of pixels constitute a third plurality of pixels forming an entirety of the third image frame;
wherein the determining of the third image frame includes:
selecting (a) a first subset of the third plurality of pixels to be generated, with temporal filtering, as the first plurality of pixels and (b) a second subset of the third plurality of pixels to be generated, without temporal filtering, as the second plurality of pixels; and
based on the selecting:
using temporal filtering to modify pixels of the first image frame, that correspond to the selected first subset of the third plurality of pixels, based on corresponding pixels of the second image frame, the modified pixels forming the first plurality of pixels; and
outputting pixels of the first image frame that correspond to the selected second subset as the second plurality of pixels without any modification, of the pixels of the first image frame that correspond to the selected second subset, that is based on the second image frame.
