Arithmetic coding method for digital image e.g. JBIG, involves renormalizing value contained in register when value is lesser than predefined value by registering lowest value among calculated values

摘要

The method involves renormalizing a value contained in a register A when the value is lesser than a predefined value. The register is renormalized by calculating values Ai where each value is multiplication of register value by multiple of 2. A value in calculated values, which is higher than the predefined value and less than or equal to all the Ai values is determined. The determined value is registered in the register.
