The power saving method includes: capturing a first image at a first time; capturing a second image at a second time, wherein a time interval between the first time and the second time is identical to one emitting cycle which is an integral multiple of the sampling period; comparing the first image and the second image to obtain a displacement; comparing the displacement with at least one threshold value; and adjusting the emitting cycle of the light source according to a comparison result of comparing the displacement and the threshold value. The present invention further provides a motion estimation device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Motion estimation device and power saving method thereof","description":"A power saving method for a motion estimation device which has a fixed sampling period and includes a light source illuminating with an adjustable emitting cycle to provide the needed light for the mo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8462115","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
