Abstract: Methods, systems, and devices for asymmetric exposure time adjustments for multi-frame (MF) high dynamic range (HDR) imaging in low light conditions are described. In some implementations, a device may receive a set of frames including short exposure frames associated with a first exposure time and long exposure frames associated with a second exposure time and may adjust the second exposure time associated with the long exposure frames to obtain a third exposure time for the long exposure frames based on detecting a low light condition associated with the set of frames. The device may adjust the second exposure time associated with the long exposure frames to obtain the third exposure time for the long exposure frames based on adding, at an image sensor of the device, an additional set of blanking lines to a set of visible lines associated with the short exposure frames.
