Abstract
A device, system and method for in vivo imaging. A device may include a typically monochrome image sensor, a plurality of illumination sources, each illumination source having different spectral characteristics, and a controller configured for effecting successive illumination of each of the illumination sources within a single image capture cycle. Typically the image sensor is a monochrome sensor. The illumination may be provided by a white light source and a plurality of filters for filtering illumination from the illumination source. A final image may be obtained by processing precursor images created using different spectra or colors.
