Disclosed is a magnetic recording medium having a magnetic layer comprising a vinyl chloride copolymer as a binder and a magnetic powder and formed on a non-magnetic support. The vinyl chloride copolymer contains a hydroxyl group and a quaternary ammonium salt, wherein the hydroxyl group is derived from a monoallyl or monomethallyl ether of a polyhydroxyl compound, or a monoallyl or monomethallyl thioether of a polyhydroxyl compound. The vinyl chloride copolymer may further contain a hydrophilic group derived from at least one monomer which is selected from carboxylic acids, sulfur-containing acids, phosphorus-containing acids and salts thereof.

摘要:
For generating a destination image (a left-eye image) from an original image and a height map thereof, the height of the height map of the original image is compared with the height of the height map of the destination image, and if a pixel of the original image is higher, the pixel of the original image is copied to a pixel of the destination image. After the pixel of the original image is copied to the pixel of the destination image, the height of the pixel of the original image is decremented. The pixel of the original image is copied in the rightward direction to pixels of the destination image until the height of the pixel of the original image becomes 0 or until a height of the pixel of the destination image becomes lower than that of the pixel of the original image. The same processes are performed on each pixel of the original image, and thereby the left-eye image is generated.
