Pixel Horizontal Lines Clause Samples

Pixel Horizontal Lines. This test pattern consists of an alternating series of 1-pixel black and white horizontal lines. The test pattern alternates black and white pixels in only the vertical direction. This pattern is useful for exactly matching the iScan’s output resolution to that of the display to achieve 1:1 pixel mapping and bypass any scaling operation which may be incorporated in the display. Its use is similar to that of the 1-pixel checkerboard, but it operates only in the vertical direction. This pattern is blacked-out for the 1080i output resolution due to the severe flicker it causes on some displays.
