Abstract
A coding apparatus for reduction and variable-length-coding of digital image data, wherein the image data is once variable-length-coded to obtain a variable length coded data. The variable length coded data is coded again to produce an amount of data. The amount of data is used to select an optimum quantization level. The variable length coded data is then coded again with the optimum quantization level to maximize a recording density of the twice coded data on a recording medium.
