HEART ACTIVITY MEASUREMENT

摘要

A method includes: obtaining, by an apparatus, instantaneous images from an optical heart activity sensor, wherein the instantaneous images characterize a heart activity data of a user; obtaining information about spatial shifts of a measuring area of the optical heart activity sensor in relation to a body tissue of the user; determining effect of the spatial shifts in the instantaneous images based on the information about the spatial shifts; enhancing the instantaneous images by decreasing the effect of the spatial shifts in the instantaneous images; and processing the enhanced instantaneous images into the heart activity data of the user.

主权项

1. An apparatus for measuring heart activity data of a user, the apparatus comprising:
at least one sensor comprising an optical heart activity sensor, wherein the optical heart activity sensor comprises a measuring head and a matrix detector, wherein the measuring head is configured to be directed towards a body tissue of the user and to form instantaneous images on the matrix detector from a light propagated through the body tissue of the user, wherein the matrix detector is configured to detect the instantaneous images, and wherein the at least one sensor is further configured to detect spatial shifts of the measuring head in relation to the body tissue of the user; a processing circuitry configured to receive the instantaneous images from the optical heart activity sensor, to determine effect of the spatial shifts in the instantaneous images based on the detected spatial shifts, and to process the instantaneous images into the heart activity data of the user; and a controller configured to enhance the heart activity data by decreasing the effect of the spatial shifts in the instantaneous images.
