摘要:
A signal processing circuit generates an image signal by performing signal processing to an imaging signal obtained through a picked up optical system that includes a lens, a diaphragm, an image sensor, and a lens barrel. A main light source detector detects a main light source contained in a picked up image of the image signal. An estimated ghost generator generates an estimated ghost based on layout information of the main light source and the imaging optical system, and structural information of the lens barrel. A matching device extracts an estimated ghost image by searching the estimated ghost in the picked up image through pattern matching. A ghost subtractor subtracts the estimated ghost image from the picked up image.
