PROBLEM TO BE SOLVED: To provide a moving image encoding device capable of suppressing generation of an excessive code amount and appropriately preventing image quality deterioration even in the case where an excessive ineffective region that is not an effective video region forming an original video image is included in a part of or an entire predetermined macro block, in accordance with a relation between a display size and a macro block unit.SOLUTION: In a moving image encoding device 1000, a first zero setting section 2 sets a signal value of a predictive error signal to "0" in the case of a signal corresponding to the ineffective region. A second zero setting section 17 sets a signal value of a differential vector signal to "0" inn the case of a signal corresponding to the ineffective region. Thus, unsuitable moving image encoding processing is prevented from being performed on the ineffective region, and the generation of the useless code amount is appropriately suppressed. |
