Imaging apparatus and medical equipment

Abstract

An imaging apparatus includes a light emitting section that emits light toward a subject, and a light receiving element that receives incident light from the subject side. The light emitting section is configured so that the light emitted from the light emitting section along an illumination direction that inclines with respect to a reference direction at an angle greater than 0° and equal to or smaller than 45° has a larger irradiation strength than the light emitted from the light emitting section along the reference direction, the reference direction being a direction perpendicular to a plane that faces the subject.

What is claimed is: 
     
         1 . An imaging apparatus comprising:
 a light emitting section that emits light toward a subject; and   a light receiving element that receives incident light from the subject side, wherein   the light emitting section is configured so that the light emitted from the light emitting section along an illumination direction that inclines with respect to a reference direction at an angle greater than 0° and equal to or smaller than 45° has a larger irradiation strength than the light emitted from the light emitting section along the reference direction, the reference direction being a direction perpendicular to a plane that faces the subject.   
     
     
         2 . The imaging apparatus according to  claim 1 , wherein
 the light emitting section is configured so that a peak wavelength of the light emitted from the light emitting section along the reference direction is longer than a peak wavelength of the incident light to the light receiving element along the reference direction.   
     
     
         3 . The imaging apparatus according to  claim 1 , further comprising
 a transmissive section that transmits the incident light from the subject side, wherein   the light receiving element receives the incident light transmitted through the transmissive section.   
     
     
         4 . The imaging apparatus according to  claim 1 , further comprising
 a lens that focuses the incident light to the light receiving element.   
     
     
         5 . The imaging apparatus according to  claim 1 , wherein
 the plane that faces the subject is parallel to a surface of a substrate on which the light emitting element is mounted.   
     
     
         6 . A medical equipment comprising
 the imaging apparatus according to  claim 1 ,   the medical equipment being configured to estimate biometric information from an image taken by the imaging apparatus.
