An image coder with a pre-record function includes a coding unit (11) which codes a motion-picture signal to generate closed GOPs or open GOPs, a buffer unit (14) in which at least one of the GOPs generated by the coding unit (11) is stored in a first-in first-out manner, a user I/F unit (12a) which receives instructions to start or stop capturing a moving picture, and a recording control unit (12b) which, before the user I/F unit (12a) receives an instruction to start capturing a moving picture, establishes a non-recording status and causes the coding unit (11) to start and continue coding the motion-picture signal so as to generate a GOP sequence including a closed GOP, and when the user I/F unit (12a) receives the instruction, switches from the non-recording status to a non-recording status and causes the coding unit (11) to generate a GOP sequence including only open GOPs.
