Abstract
An image processing apparatus is provided which minimizes reduction in S/N ratio and deterioration in resolution feeling at the lens periphery when the peripheral light amount drop correction of the lens is performed. An image processing LSI to perform the peripheral light amount drop correction of the imaging lens includes a space-direction noise removal correction part and a time-direction noise removal correction part. As the distance from the lens center position increases, the space-direction noise removal correction part reduces the noise reduction correction intensity to the image region to which the light amount drop correction gain is added in each image. As the distance from the lens center increases, the time-direction noise removal correction part increases the noise removal correction intensity to the image region to which the light amount drop correction gain is added in each image.
