发明名称 Image processing apparatus for removing an isolated point
摘要 An image processing apparatus efficiently removes an isolated point. A pixel area comprising a matrix area and a line area extending from the matrix area is defined. The matrix area includes a plurality of pixels forming a matrix so that a center pixel which is being processed is located in the center of the matrix. The line area includes a predetermined number of pixels along a scan line in which the center pixel is included so that the predetermined number of pixels extend from the matrix area. The center pixel is subjected to an isolated point removing process by referring to the pixels included in the pixel area.
