Application Number: JP,2023-103835
Category (FI): A61B5/02,310@A
Stage: PROBLEM TO BE SOLVED: To obtain a pulse wave estimation device capable of suppressing a decrease in estimation accuracy of a pulse wave.SOLUTION: A pulse wave estimation device 1 includes: a photographed image acquisition unit 11 that acquires a photographed image obtained by imaging a person; a skin region detection unit 12 that detects skin regions of the person from the photographed image; a measurement region setting unit 13 that sets regions obtained by dividing the skin region in the photographed image into prescribed regions as multiple measurement regions for extracting luminance signals indicating luminance variations; a luminance signal extraction unit 14 that extracts the luminance signals on the basis of the luminance variations in the measurement regions on the photographed image; and a pulse wave estimation unit 16 that estimates the pulse wave of the person on the basis of the extracted luminance signals. The measurement region setting unit 13 resets, when a ratio of the measurement regions with the number of pixels being equal to or greater than a predetermined reference value among the set multiple measurement regions is less than a threshold, the measurement regions such that the ratio becomes equal to or greater than the threshold.SELECTED DRAWING: Figure 1 (Grant)
