An error detection unit (11) of a variable-length decoding unit (10) can detect an error that occurs in a coded picture to be decoded to send error information on the error to a control unit (8). When the control unit (8) determines that an error has been detected or the frequency of occurrence of errors is large enough to have a deleterious effect on decoded pictures based on the error information, the control unit (8) stops the transfer of decoded picture data to a display unit (9). After that, the control unit (8) restarts the transfer of decoded picture data to the display unit (9) when it determines that no error has been detected or the frequency of occurrence of errors is too small to have a deleterious effect on decoded pictures. As a result, any hard-to-see picture disturbed due to occurrence of errors, witch may provide a sense of incompatibility for users, can be prevented from being displayed.
