Method and Apparatus for Correction of Non-Invasive Blood Glucose Measurement
2015
The present invention relates to a non-blood glucose measurement correction method and apparatus, to a method which corrects the glucose measurement signal from the image image of the white light reflected from the skin. In the present invention, there is provided a method and apparatus for extracting blood to measure blood glucose a fundamentally correct blood glucose signal. This is generated by the white light filtered by irradiating the white light to the skin by using a white light source, the step of filtering by the white light reflected from the skin to a first wavelength filter and a second wavelength filter, the first wavelength filter determining, based on the image of the image capture a first signal comprising a glucose signal and a pulse signal, first on the basis of the image of the image generated by the white light filtered by a second wavelength filter to obtain a second signal including a pulse signal step, may be by subtracting the second signal from the first signal comprise the steps of calculating the blood glucose level in the subcutaneous blood vessels based on the blood glucose signal phase, and the obtained signal to obtain the blood sugar. According to the disclosed non-blood glucose measurement correction method and apparatus, it can be extracted in a way that is fundamentally a blood glucose signal in real time.
