An apparatus includes a sensor and a processor. The sensor may be configured to generate a first video signal. The processor may be configured to search for a flickering effect in a frame of the first video signal, determine a location and a region of pixels to modify within the frame in response to the flickering effect, determine a modification based on the flickering effect, perform the modification of the region of pixels by determining average values of pixels based on the location of the region of pixels over consecutive frames of the first video signal and generate a second video signal in response to the modification of the region of pixels and the first video signal. The second video signal may present a modified version of the region of pixels to mask the flickering effect when viewing the second video signal on a display.
