Abstract
An apparatus for estimating biological information of a user may include a light source configured to emit light to an object of the user; an image sensor comprising a pixel array, and configured to acquire successive image frames by detecting light scattered or reflected from the object of the user; and a processor configured to: select a predetermined number of pixel-rows from among pixel-rows of the image sensor, detect signal intensities in the predetermined number of pixel-rows for each image frame of the successive image frames, correct the signal intensities, combine the signal intensities for each image frame of the successive image frames based on correcting the signal intensities, acquire a photoplethysmogram (PPG) signal based on combining the signal intensities, and estimate the biological information of the user based on the PPG signal.
