Abstract: Methods, systems, and devices for anchor frame switching in an imaging system are described. A device may generate a pixel map based on a set of frames. A first subset of frames of the set of frames have a first exposure and a second subset of frames of the set of frames have a second exposure different than the first exposure. The device may determine a region of the pixel map representing motion between at least two frames of the first set of frames. If the device determines that a quantity of motion pixels in the region is higher than a threshold, the device may select a short exposure frame as an anchor frame, beginning at a later frame. Otherwise, the device may maintain using a long exposure frame as the anchor frame.
