A relatively long, narrow defect in a digital image is repaired by identifying an elongated area to be repaired, and by automatically calculating pixel color/shade values within the area to be repaired from pixel values in the vicinity of the perimeter of the elongated area. Preferably, a user identifies an elongated rectangular area to be repaired on an interactive display. The computer automatically generates the pixel coordinates of a pair of parallel lines constituting the opposite long sides of the rectangle, and a set of line segments running between the long sides. The interior pixels of the rectangle are then filled by interpolating color values along each line segment. Since this method is not guaranteed to fill all pixels, the system optionally maintains a map of pixels filled and not filled while performing this method, and after completion, performs an additional step of assigning to any unfilled pixels a value based on the average of all adjacent pixels. For long, narrow defects, particularly those introduced by creasing, the automated digital image repair method herein described generally produces images without significant visually noticeable defects, and does so without undue effort on the part of the user.
