Abstract: Physiological parameter detecting apparatuses and methods of detecting the physiological parameters are provided. A physiological parameter detecting apparatus includes: a light source configured to emit a light onto a region of an object; an optical path converter configured to receive the light returning from the object and convert an optical path of the received light; an optical detector configured to detect the light that has the converted optical path; and a controller configured to extract physiological information of the object from the detected light.

Abstract: The method includes simultaneously illuminating a scene by at least two light sources, each light source emitting structured light having a spatial pattern, a wavelength and/or a polarization, wherein the spatial pattern, the wavelength and/or the polarization of each structured light differ from each other, respectively, capturing an image of the scene simultaneously illuminated by the at least two light sources by an imaging sensor through a filter array, wherein one pixel of the imaging sensor captures the image through one filter of the filter array, calculating, for each pixel, intensity values of direct and global components of the light received by the pixel from a system of equations compiled for each joint pixel, and performing, for each pixel, image correction by assigning to each pixel its calculated intensity value of the direct component to obtain a corrected image.
