Abstract
A compressed data storage apparatus is provided with a compressing circuit for generating compressed data by compressing digital data from a camera section, a buffer memory for storing the compressed data temporarily, a disk device for storing the compressed data stored in the buffer memory at a rate faster than a rate at which the buffer memory stores the compressed data, and a system controller for increasing a compression ratio of the compressing circuit when detecting that the disk device has become unable to record the data. According to the above arrangement, in the event that the disk device becomes unable to store the data due to vibrations or an impact, the data compression ratio is increased, whereby the rate at which the buffer memory stores the data is reduced. Consequently, the capacity of the buffer memory can be reduced, and therefore, it has become possible to provide an inexpensive compressed data storage apparatus with excellent resistance to vibrations.
