Abstract:
As an embodiment of the present invention, a data processing apparatus stores as cache data, in a RAM, data included in a predetermined fixed length area of a stored file. The PC sends a transfer request for cache data to the data processing apparatus, and the data processing apparatus sends the cache data to the PC. The PC extracts thumbnail images and EXIF data from the received cache data. Therefore, the data processing apparatus does not need to extract thumbnail images, etc.
Abstract(Chinese):

作为本发明的实施例，数据处理装置将包含在存储文件的预定固定长度区域中的数据作为高速缓存数据存储在RAM中。 PC向数据处理装置发送缓存数据的传送请求，数据处理装置向PC发送高速缓存数据。 PC从接收到的高速缓存数据中提取缩略图和EXIF数据。 因此，数据处理装置不需要提取缩略图等。
