Description

  The present invention relates to an imaging apparatus capable of monitoring a state of a part that is subject to various restrictions when a person works, such as the seabed, with a clear image or recording and shooting clearly. It is intended to improve sex.

  Carbon dioxide emissions have been found in submarine hydrothermal activity areas occurring in active submarine crust. In recent years, from the viewpoint of global warming, the sequestration of recovered carbon dioxide in the ocean has been studied, and elucidating the dilution status of the isolated carbon dioxide in the ocean is the setting of an effective sequestration method And is useful for understanding environmental changes.

  For this reason, attempts have been made to observe carbon dioxide droplets released in the seafloor hydrothermal activity region. Carbon dioxide ejected from the ocean floor is thought to rise as droplets, and gradually dissolves into the sea during the ascent process and is thought to disappear. Therefore, it is possible to mount a photographing device on a submarine, etc., shoot the state of carbon dioxide droplets ejected from the seabed as they float, and analyze the captured images to analyze the behavior of carbon dioxide. It is considered an effective means of grasping. Specifically, it is conceivable to use a working machine (for example, see Patent Document 1) that performs work in the sea, and mounts an imaging device that has been subjected to waterproofing processing and the like to photograph carbon dioxide droplets by remote control. It is done.

  In order to analyze a photographed image, it is necessary to record, and it is conceivable that a video camera for recording is mounted on the work machine. However, since the recording time is limited, it is realistic to check the carbon dioxide ejection site with a monitor provided in the work machine and operate the video camera for recording at the carbon dioxide ejection site. Therefore, the actual situation is applicable only to a working machine equipped with a monitor. In addition, it is difficult to obtain a clear image with a normal photographing apparatus (CCD camera or the like), and the actual situation is that the behavior of carbon dioxide has not been accurately grasped.
