Processing and providing an image in which a plurality of symbols are encoded

A reception apparatus, comprising:

• circuitry configured to
• receive or retrieve an image in which one of a plurality of predetermined run-in patterns and a plurality of symbols is encoded using a set of luminance values,
• determine which of the plurality of nu-r patterns is encoded in the image,
• determine a slice point used to determine data values of the plurality of symbols encoded in the image based on which of the plurality of predetermined run-in patterns is determined to be encoded in the image, and
• determine the data Values of the plurality of symbols encoded in the image based on the determined slice point.

A method for processing an image in which a plurality of symbols is encoded, the method comprising:

• receiving or retrieving, by circuitry of a reception apparatus, the image in which one of a plurality of predetermined run-in patterns and the plurality of symbols is encoded using a set of luminance values,
• determining, by the circuitry, which of the plurality of run-in patterns is encoded in the image.
• determining, by the circuitry, a slice point used to determine data values of the plurality of symbols encoded in the image based on which of the plurality of predetermined run-in patterns is determined to be encoded in the image, and
• determining, by the circuitry, the data values of the plurality of symbols encoded in the image based on the determined slice point.

A non-transitory computer-readable medium storing instructions which, when executed by a computer, causes the computer to perform a method for processing an image in which a plurality of symbols is encoded, the method comprising:

• receiving or retrieving the image in which one of a plurality of predetermined run-in patterns and the plurality of symbols is encoded using a set of luminance values,
• determining which of the plurality of run-in patterns is encoded in the image,
• determining a slice point used to determine data values of the plurality of symbols encoded in the image based on which of the plurality of predetermined run-in patterns is determined to be encoded in the image, and
• determining the data values of the plurality of symbols encoded in the image based on the determined slice point.
