US 2019/0159732 A1 · WEARABLE DEVICE AND ASSOCIATED METHOD

Abstract

A wearable device includes: a light source, a sensor and a processor. The light source selectively operates in an illuminating mode or a non-illuminating mode, and generates an auxiliary light passing through a physical body in the illuminating mode. The sensor captures detecting images from the physical body, wherein the detecting images include at least one illuminating image captured while the light source is in the illuminating mode, at least one pre-illuminating image captured before the illuminating image is captured while the light source is in the non-illuminating mode, and at least one post-illuminating image captured after the illuminating image is captured while the light source is in the non-illuminating mode. The processor generates physiological information of the physical body according to the illuminating image, the pre-illuminating image and the post-illuminating image.

Dependent claims

A wearable device, comprising:

a light source, selectively operating in an illuminating mode or a non-illuminating mode, wherein the light source generates an auxiliary light passing through a physical body in the illuminating mode;
a sensor, arranged to capture detecting images from the physical body, wherein the detecting images comprise at least one illuminating image captured while the light source is in the illuminating mode, at least one pre-illuminating image captured before the at least one illuminating image is captured while the light source is in the non-illuminating mode, and at least one post-illuminating image captured after the at least one illuminating image is captured while the light source is in the non-illuminating mode;
and
a processor, coupled to the sensing circuit, wherein the processor is arranged to generate a physiological information of the physical body according to the at least one illuminating image, at least one pre-illuminating image and the at least one post-illuminating image.
