US 2007/0182846 A1 · Portable image pickup device

Abstract

The invention provides a portable image pickup device which is capable of solving the lengthening of an activation time caused in accordance with a structure of a file system. When an operating system is activated, unused cluster information corresponding to real data stored in a hard disc drive (105) is acquired from an FSINFO region (103). Hence, it is possible to omit a work for retrieving an FAT region (124) in processing for initializing a file system, and thus it is possible to shorten a time required to initialize the file system. As a result, it is possible to shorten a time required for processing for activating the operating system, and it is possible to enhance mobility from a phase in which a power source of a portable image pickup device (1) is turned ON to a phase in which the portable image pickup device (1) becomes available.
