A coding apparatus (10) has a data compressor (15) for compressing input data under a given condition of compression to deliver compressed data, a detecting unit (6) for detecting a quantity of the compressed data, a designating unit (13) for designating a target compressed data quantity which is so set as to be less than, by a predetermined quantity, a maximum transmission data quantity of output data to be transmitted externally, a comparator (7) for comparing the target compressed data quantity with the detected compressed data quantity to deliver a comparison result, a setting unit (8) for setting a compression condition in accordance with the comparison result, and a limiter (14) for applying a comparison condition of a predetermined lower limit value to the compressor (15) when the set compression condition is less than a predetermined reference value. <IMAGE> |
