Beschreibung
Zusammenfassung:	An image sensor includes unit pixels of a first pixel group sharing a first floating diffusion region and associated with a single color filter, and unit pixels of a second pixel group sharing a second floating diffusion region and associated with the single color filter. Control logic may generate an image by obtaining capacitance having a first value from the first floating diffusion region at a first time, and obtaining capacitance having a second value different from the first value from the second floating diffusion region at a second time following the first time. The first pixel group and the second pixel s group have different sensitivity levels.
