Patent ID: 8339489

Claim:
An image photographing apparatus comprising: a filter unit comprising: a first filter region comprising: a first sub-filter region which passes a first wavelength band of an incident light signal corresponding to a complementary color of a first color; and a second sub-filter region which passes a second wavelength band of the incident light signal corresponding to a complementary color of a second color; a second filter region which passes all wavelength bands of the incident light signal; and a third filter region including a white filter which blocks an infrared wavelength band of the incident light signal; and an image sensor unit to sense an image from the light signal that passes through the filter unit, wherein each of the first sub-filter region and the second sub-filter region is formed of any one of a cyan filter, a magenta filter, and a yellow filter with a filter of the first sub-filter region being different than a filter of the second sub-filter region, and wherein the first sub-filter region and the second sub-filter region are formed adjacent to each other in a first row and the second filter region and the third filter region are formed adjacent to each other in a second row that is consecutive to the first row.
