ABSTRACT:
An image signal processing system and an electronic imaging device are provided in which a shading correcting circuit carries out shading correction by multiplying image data by a gain which is proportional to a distance from a center of an image; a noise reduction filter carries out noise reduction processing by using a value which varies inversely proportionately to the gain; and a contour correction processing circuit carries out substantially uniform contour correction at all regions of the image, independently of the shading correction and the noise reduction processing.
