摘要： The present invention makes possible recording motion pictures accurately starting at a point where a start recording event is received. The recording includes those pictures prior to the start recording event using a picture compressing method that compresses pictures both before and after the starting event, typically using the MPEG2 compression system. To make the above recording method possible, the present invention provides a signal processor and a photographic device that can search a motion vector for changing the object searching range properly, set an compression amount allocation for each picture type, and allow optimized parameters to be set when a start recording event is generated. The pictures processed before the start recording event is generated are stored in a memory buffer and on a recording medium so as to be used for recording or reproduction data entered after the recording starting time.

摘要翻译：本发明使得可以在接收到开始记录事件的点准确地开始记录运动图像。记录包括在开始记录事件之前使用图像压缩方法的那些图像，该图像压缩方法在起始事件之前和之后压缩图像，通常使用MPEG2压缩系统。为了使上述记录方法成为可能，本发明提供一种能够正确搜索运动矢量以改变对象搜索范围的信号处理器和摄影装置，为每种图像类型设置压缩量分配，并且允许设置优化的参数当生成开始记录事件时。在开始记录事件之前处理的图像被存储在存储缓冲器和记录介质中，以便用于在记录开始时间之后输入的记录或再现数据。

摘要： A moving picture coding/decoding apparatus capable of rapidly finding out a content of recorded moving picture data without completely decoding this moving-picture data content is constructed of an image coding/decoding unit (12) for coding/decoding a picture signal containing moving-picture information, a storage control unit (15), and a storage unit (16). In a small image generating unit (13), reduced resolution image signal (namely, "small image data") for indexing the original image signal is generated by sampling the image signal, or cutting out a portion of an image formed by the picture signal. This small image data is stored via the storage control unit (15) into the storage unit (16), while this small image data is correlated with the decoded image data obtained from the image coding/decoding unit (12). A selection is made of any one of the small image data read from the storage unit (16) and the restored image data derived from the image coding/decoding unit (12). Then, the selected image is displayed.
