A method of operating an inspection device includes collecting a plurality of successive image frames using an image sensor of the inspection device and displaying the plurality of successive image frames on a display of the inspection device. The method includes processing, via a processor of the inspection device, each image frame of the plurality of successive image frames by determining a motion parameter of each respective image frame and adding each respective image frame to a frame buffer when the respective image frame is motion free. The method includes receiving a control signal from a user interface of the inspection device requesting an image frame output. The method further includes determining, via the processor of the inspection device, a noise-reduced image frame from the frame buffer in response to the control signal and outputting the noise-reduced image frame in response to the control signal.
