Abstract

See full text

There is provided a system for performing ambient light image correction. The system comprises a light source, a rolling shutter imaging unit configured to capture a plurality of images of the object at an exposure time shorter than the wave period of the pulsed illumination from the light source, and a control unit configured to generate a first composite image comprising a plurality of bright bands from the plurality of captured images by combining sections from the plurality of captured images which correspond to bright bands, generate a second composite image comprising a plurality of dark bands from the plurality of captured images by combining sections from the plurality of captured images which correspond to dark bands, and generate an ambient light corrected image based on a difference in pixel information between the first composite image and the second composite image.
