A method of identifying defective pixels included in a digital image. The method includes the steps of designating a pixel adjacent the defective pixels in the digital image, setting an evaluation area, setting a defective pixel candidate, computing, as a line average, an average pixel value of each of lines above, below, leftward and rightward of the defective pixel candidate, diminishing the evaluation area by selecting an upper line, a lower line, a left line and a right line, computing a threshold pixel value for determining the defective pixels, from an average pixel value of each line, and comparing values of all pixels with the threshold pixel value to determine the defective pixels.
