Abstract
A defect pixel correction apparatus includes an internal memory which associates and stores a position of a defect pixel with an order of the defect pixel in an image sensor and a processor which corrects a pixel signal of an object pixel based on a pixel signal of an adjacent normal pixel when the adjacent normal pixel is present in the neighborhood of the object pixel and corrects the pixel signal of the object pixel based on a pixel signal of an adjacent defect pixel of a lowest order when the adjacent normal pixel is not present and the adjacent defect pixel of a lower order than an order of the object pixel is present.
