IMAGE STORAGE SYSTEM

Abstract

An image storage system effectively stores image data captured by an image capture device in a plurality of image storage devices. Each of the image storage devices includes a storage unit for storing image data. An image storage device performing as a master among the image storage devices includes an image reception unit for receiving the image data captured by the image capture device. A storage unit provided in each of the image storage devices distributes the image data received by the image reception unit provided in the image storage device performing as the master to the respective image storage devices so as to be stored there.

Claims

1. An image storage system comprising: an image capture device, anda plurality of image storage devices for storing image data captured by the image capture device,wherein each of the image storage devices includes a storage unit for storing image data,an image storage device serving as a master among the plurality of image storage devices includes an image reception unit for receiving the image data captured by the image capture device, andthe image data received by the image reception unit provided in the image storage device serving as the master is distributed to each of the plurality of image storage devices and stored in the storage unit provided in each of the plurality of image storage devices.

2. The image storage system as claimed in claim 1, wherein each of the plurality of image storage devices includes a check unit for checking whether an other image storage device is normally operating, andeach of the image storage devices operates according to a mode based on a check result obtained by the check unit.

3. The image storage system as claimed in claim 2, wherein if the check result obtained by the check unit indicates that at least one of the image storage devices has stopped operation, the storage unit provided in the other image storage device stores all the image data captured by the image capture device in the other image storage device.

4. The image storage system as claimed in claim 1, wherein the image storage device serving as the master includes an image output unit for acquiring the image data stored in the storage unit provided in each of the plurality of image storage devices and arranging the data in the time series for output.

5. The image storage system as claimed in claim 1, wherein the image capture device includes a compression unit for compressing the captured image data for each set of a predetermined number of frames of odd numbers and for each set of a predetermined number of frames of even numbers, andthe storage unit provided in each of the plurality of image storage devices distribute the compressed image data for each set of a predetermined number of frames as a unit to each of the plurality of image storage devices so as to be stored there.

6. The image storage system as claimed in claim 1, wherein the image storage device serving as the master includes an image output unit for acquiring the image data stored in the storage units provided in the image storage devices and arranging the data in the time series for output.

7. The image storage system as claimed in claim 1, wherein the image capture device includes a compression unit for compressing the captured image data for each set of a predetermined number of frames of odd numbers and for each set of a predetermined number of frames of even numbers, andthe storage units provided in the image storage devices distribute the compressed image data for each set of a predetermined number of frames as a unit to the image storage devices so as to be stored there.
