MOTION CLUTTER SUPPRESSION FOR IMAGE-SUBTRACTING CAMERAS |
摘要 |
Embodiments of the present invention relate to systems and methods for minimizing motion clutter in image-generation devices. Temporally-interleaved image-subtraction reduces the magnitude of motion clutter and has no adverse effect on the desired ambient-light cancellation of static images. Embodiments of image-generation devices employing temporally-interleaved image-subtraction include single, double, triple, and series accumulator configurations. All four embodiments allow synchronization with scene illuminators and may be implemented on a single electronic chip. Temporally-interleaved image subtraction is particularly well suited for use in video eyetracking applications where ambient light and scene motion can cause significant problems. |
