图像编码装置、摄像机、集成电路以及图像编码方法
摘要：
一种具有预录功能的图像编码装置，包括：编码部(11)，通过对所述影像信号进行编码从而生成封闭画面组或开放画面组；缓冲器部(14)，以先入先出的方式记忆由所述编码部生成的至少一个画面组；用户接口部(12a)，接受拍摄的开始以及结束的指示；以及记录控制部(12b)，控制编码部(11)，以使得在用户接口部(12a)接受拍摄开始指示之前，在确保非记录状态的状况下，使编码部(11)开始编码，并使编码持续进行，从而生成包含封闭GOP的GOP列，在用户接口部(12a)接受拍摄开始之时，使非记录状态切换为记录状态，并使编码部(11)生成仅由开放GOP构成的GOP列。
摘要（英）：

An image coder having a pre-recoding function comprises a coding unit (11) for generating a closed GOP or an open GOP by coding a video signal, a buffer unit (14) for storing at least one GOP generated by the coding unit (11) in a first-in first-out way, a user I/F section (12a) for receiving start and end instructions of imaging, and a recording control section (12b) which sets up a non-recording mode before the user I/F section (12a) receives an imaging start instruction, allows the coding unit (11) to start and continue coding and thereby to generate a GOP sequence including a closed GOP, changes the mode from the non-recording mode to a recording mode when the user I/F section (12a) receives the imaging start instruction, and controls the coding unit (11) to generate a GOP sequence including only open GOPs.
