Method and apparatus for photographing an image using light from multiple light sources

摘要

Provided is a photographing apparatus including: first and second light sources that respectively transmit a first light having a first spectral radiant characteristic and a second light having a second spectral radiant characteristic; an image device that captures an image of a subject by using the transmitted lights sources; a storage unit that stores a first reference output ratio corresponding to the first light and a second reference output ratio corresponding to the second light; and a determiner that determines a regular reflection area of the light sources by using a first captured image acquired by capturing an image of the subject by using the first light, a second captured image acquired by capturing an image of the subject by using the second light, the first reference output ratio, and the second reference output ratio.

1. A photographing apparatus comprising:
a plurality of light sources that respectively transmit a first light having a first spectral radiant characteristic and a second light having a second spectral radiant characteristic; an image device that captures an image of a subject by using the first and second lights; a storage unit that stores a first reference output ratio corresponding to the first light and a second reference output ratio corresponding to the second light; and a determiner that determines a regular reflection area of the plurality of light sources by using a first captured image acquired by capturing an image of the subject by using the first light, a second captured image acquired by capturing an image of the subject by using the second light, the first reference output ratio, and the second reference output ratio, extracts a first regular reflection candidate area from the first captured image by using the first reference output ratio, extracts a second regular reflection candidate area from the second captured image by using the second reference output ratio, and determines an area overlapping between the first and second regular reflection candidate areas as the regular reflection area of the plurality of light sources; wherein the first reference output ratio is an output ratio between pixels output from the imaging device when capturing an image of the subject by using the first light, and the second reference output ratio is an output ratio between pixels output from the imaging device when capturing an image of the subject by using the second light.
