This letter describes a method for reducing moiré in a captured image of LCD display. Moiré often appears in a shot image by a CCD camera because of the interference between CCD cells and luminescence devices. The method uses two images with the just focused and the off-focused. Through FFT, only moiré patterns are removed without blurring the contour of an uneven area defect in LCD display. The experimental result showed that the moiré was almost removed by the proposed method.
