Abstract: An image processing system is disclosed. The system includes a first light source operable to illuminate an image plane in a first direction and a second light source operable to illuminate the image plane from a second direction. Also included is a sensing device operable to detect light from the first and second light source that interacted with the image plane. A processor operable to receive information from the sensing device and determine an image and image defects is coupled to the sensing device.

Abstract: A system and method for correcting defects in an image. A correction area surrounding the defective pixel is dynamically chosen to include a predetermined percentage of non-defective pixels. The percentage is varied as a function of the size of the surrounding region, such that the percentage decreases as the size of the region increases. The shape of the surrounding area may be varied to further enhance the correction procedure. A center of gravity is maintained around the defective pixel by defining subregions surrounding the pixel.

Abstract translation: 一种用于校正图像缺陷的系统和方法。 动态地选择围绕缺陷像素的校正区域以包括预定百分比的无缺陷像素。 该百分比随着周围区域的大小而变化，使得该百分比随着区域尺寸的增加而减小。 可以改变周围区域的形状，以进一步增强校正过程。 通过限定像素周围的子区域，重心被保持在缺陷像素周围。
