    摘要： An apparatus for storing high definition image signals capable of processing high definition image signals and low definition image signals using the same apparatus. A storage medium is provided with an interface of low definition image signals. High definition image signals are compressed, transformed into a format according to the specifications of the interface of low definition image signals and are then stored in the storage medium. The compressed image signals taken out from the storage medium are subjected to the format reverse transform for expansion to restore the original high definition image signals. The format-transformed compressed high definition image signals and the compressed high definition image signals taken out from the storage medium are transmitted over a transmission medium via low definition image interface and are, as required, stored in the storage medium or put to other processings, and are then expanded to restore the original high definition image signals.

    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.
