    Abstract: A method of generating an image using an image capturing device includes generating an imperfect image excluding data corresponding to one or more pixel sensors by capturing an object while the object is focused. A defocused image is generated to include the data corresponding to the one or more pixel sensors generated using neighboring pixel sensors around the one or more pixel sensors while the object is defocused. The data corresponding to the one or more pixel sensors is extracted based on data in the generated imperfect image and data in the generated defocused image. A final image is then generated by reflecting the extracted data to at least one of the generated imperfect image or the generated defocused image.
