Abstract: A pulse wave detection device color converts a frame image of a moving image from RBG components to YIQ components, and identifies an eye section using the eye color of a user prepared in advance with a Q component. Next, the pulse wave detection device uses the Y values of the eye section to detect the brightness of the imaging environment. Then, the pulse wave detection device detects a pulse wave signal Qm on the basis of the average of the Q-values of a skin section in the frame image, corrects a change in the brightness by subtracting from Qm the average value Ye of the Y values of the eye section, and thereby outputs a post-brightness-correction Qm. As a result, a pulse wave can be successfully detected even if the brightness is changing because the user is moving in a vehicle or the like.

Abstract: A pulse wave detection device color converts a frame image of a moving image from RBG to HSV components, and identifies a skin section using the skin color of a user prepared in advance with an H component. The device converts the skin section of the image to YIQ components, and takes Qm as a pulse wave signal, Qm being obtained by averaging the Q values of the pixels. The device then obtains a chronological change in the pulse wave signal Qm and outputs the change as a pulse wave. Accordingly, it is possible to exclude disturbance factors from the pulse wave detection target, and successfully detect a pulse wave. The identification of the skin section is performed using the H component to identify candidate pixels, and using the S component to narrow down the candidate pixels to the target, so high-precision identification of the skin section is possible.
