Endoscopes (also referred to as scopes or fiberscopes), which can perform various therapeutic procedures using the following techniques, are widely used.

Furthermore, various electronic scopes are in use that use solid-state imaging devices such as charge-coupled devices (abbreviated as COD) as imaging means. This electronic scope has higher resolution than a fiberscope, and it is easier to record and play back images.
It has the advantage that image processing such as image enlargement and comparison of two screens can be easily performed.

The endoscopic image visualized by the electronic scope is recorded in an image recording device, and recently there has been a strong desire to back up the images recorded in the image recording device.

Furthermore, Japanese Patent Application Laid-Open No. 1983-7567 discloses a technique in which the same data is recorded twice in sectors that are not adjacent to each other when recording on an optical disk whose recording area is divided into sectors. However, in the conventional example described above, data is recorded in two sectors on the same optical disc, so if the optical disc on which it is recorded is broken or lost, images cannot be reproduced. Furthermore, in order to have the same information twice, the amount of data stored is doubled, and the storage space is also doubled.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an endoscopic image file device that has an effective backup method without increasing the amount of data.

As mentioned above, in this example, since images for one examination are recorded using two recording devices, there is a possibility that the recording medium recorded by one of the recording devices becomes unplayable (for example, lost or damaged). However, the images from that test can be reproduced. Furthermore, since the number of recorded sheets does not change, a large storage space is not required.

Furthermore, since there are multiple recording devices, the same examination can be searched at multiple locations by taking the recording medium on which images are recorded to another location.

In this embodiment, two recording devices were used, but three or more recording devices may be used.

Also, although recording was performed every other sheet, it may be possible to record every second sheet, or by weighting one of the devices, for example, one recording device records 2 sheets while the other recording device prints 2 sheets. You can also record it with

Furthermore, the recording devices may be of the same model, or may be of different recording methods (for example, analog recording and digital recording, write-once type and rewritable type, etc.), or of different recording capacities (for example, 100-sheet recording and ioooo-sheet recording) may be used.

[Effects of the Invention] As explained above, according to the present invention, images are recorded by a plurality of recording devices, so that the data load is not increased.
A valid backup can be made.
