A B S T R A C T A surface containing encoded information bordered by bars where both the bars and the information contrast with a background is detected as to orientation and location and the information read by sampling the video scan output of a television camera which is designed to raster scan the image formed therein. The camera may be caused to scan with alternating rasters at an angle, preferably 90°, to one another while the orientation of the raster relative thereto is determined. The orien- tation of the raster scan may be rotated by electronic means, to provide the desired orientation of the raster relative to the information.
