    Abstract: A heartbeat detection device includes a bone conduction microphone that converts, into a signal, displacement on the body surface of a user in a thickness direction of the body of the user, and an extractor that extracts a first frequency component and a second frequency component which are included in the signal. The first frequency component is based on audio information of the user, and the second frequency component is based on heartbeat information of the user. The heartbeat detection device is capable of estimating the physical and psychological state of the user based on the heartbeat information by extracting both the audio information and the heartbeat information, from a signal that has been output by the bone conduction microphone.

    Abstract: A display system includes an attitude detection device configured to detect an attitude change amount of a moving body, and a correction processing device including a vibration detector configured to determine whether or not an attitude change in the moving body having a specific frequency band component has been continuously generated based on the attitude change amount. The correction processing device updates a correction amount of a display position of the image based on the attitude change amount when the vibration detector determines that the attitude change having the specific frequency band component has not been continuously generated, and sets an absolute value of the correction amount to be equal to or less than an absolute value of a correction amount at a time of last determination when the vibration detector determines that the attitude change having the specific frequency band component has been continuously generated.

    Abstract: A camera body according to the present disclosure is one on which a lens unit is detachably mounted. The lens unit includes an optical system to form an optical image of a subject onto an imaging surface. The camera body includes: an imaging part having the imaging surface to form an image by converting light incident from the optical system into an electric signal; a first blur-detecting part capable of detecting motion of the camera body at least in a pitching, yawing, and rolling directions; a first blur-correction part capable of correcting a blur caused by the motion in the pitching, yawing, and rolling directions, based on a result of the detection by the first blur-detecting part; and a first controller, capable of communicating with the lens unit, controlling both the first blur-detecting part and the first blur-correction part. The first controller acquires information indicating whether or not the lens unit includes a second blur-correction part to correct a blur caused by the motion in the pitching and yawing directions. The first blur-correction part corrects only a blur caused by the motion in the rolling direction when the lens unit causes the second blur-correction part to operate.
