High dynamic range video capture using variable lighting

Abstract:

A system and method is generally provided for producing a high dynamic range video. The system includes a probe and a computer communicatively coupled to the probe. The probe includes a camera and a light source. Further, the probe produces a plurality of frames. The computer includes at least one processor and at least one memory device. The memory device contains instructions configured to combine the plurality of frames into composite frames. The instructions are further configured to filter out portions of frames captured below a first threshold of light and portions of frames captured above a second threshold of light. The light source modulates a lighting characteristic, and the camera captures a first video with the modulated light source to produce a plurality of frames defining a plurality of lighting characteristics. Further, the computer combines the plurality of frames into a second video including a plurality of composite frames.
