Abstract
An image generating apparatus including a filtering unit to filter a plurality of light signals including a first filter region and a second filter region. The first filter region may allow a complementary color wavelength band of an incident light signal to pass through and the second filter region may allow a whole wavelength band of the incident light signal to pass through. At least one of the first filter region and the second filter region includes two sub-regions configured to pass filtered light signals with two different sensitivities. In addition, an image sensing unit may sense at least one of the filtered light signals of different sensitivities in the complementary color wavelength band and the filtered light signals of different sensitivities in the whole wavelength band from the filtering unit and an image processing unit may generate an image based on the sensed light signals.
