Abstract
A pulse wave estimating device includes processing circuitry configured to; acquire a captured image of a human; detect a skin region of the human on the captured image; set, as a plurality of measurement regions for extracting luminance signals representing luminance changes, regions formed by dividing the skin region on the captured image in a predetermined manner; extract the luminance signals on a basis of the luminance changes in the measurement regions on the captured image; and estimate a pulse wave of the human on a basis of the extracted luminance signals; perform measurement region resetting, when a ratio of measurement regions, in which the number of pixels is equal to or greater than a preset reference value among the set plurality of measurement regions, is lower than a threshold, in such a manner as to make the ratio of measurement regions equal to or higher than the threshold.
