The conventional underwater camera has a problem in that it is difficult to take normal photography because the fogging phenomenon occurs according to the temperature difference between the inside of the water and the upper side of the water surface, and the camera lens is damaged by the underwater pressure.

As a prior art previously applied by the same applicant, as disclosed in Korean Patent Publication No. 10-1520961 "Underwater Camera" (registration date: June 11, 2015), a casing in which an accommodating space is formed so that a camera module is embedded therein; , a connector coupled to one side of the casing and for transmitting a signal of the camera module to an external control side, a lens coupled to the other side of the casing so that a peripheral portion is embedded in the other side of the casing and connected to the camera module, and the other side of the casing Airtight means coupled to the lens side to block the inflow of water in the water, coupled to one side of the casing to flow out air in the hermetic space located between the hermetic means and the other side of the casing, and within the hermetic space A valve for supplying an inert gas is provided.

In addition, as disclosed in Korean Patent Publication No. 10-1822096 "Underwater Camera Device" (registration date: 2018.01.19), in the other prior art previously applied by the same applicant, the receiving space is formed so that the camera module is embedded therein. and a casing provided with a holder part extending inwardly on the other side and having a holder hole formed in the center into which a lens is fitted, a connector part coupled to one side of the casing and transmitting a signal of the camera module to an external control part, and the other side of the casing A lens coupled so that a peripheral portion is embedded in the camera module and connected to the camera module, an airtight means coupled to the other side of the casing to block the inflow of water in water to the lens side, and the airtight means provided on the other side of the casing and injection means for injecting the liquid silicone liquid into the space positioned between the first window member of the casing and the holder portion of the casing; The injection means injects the silicone liquid into the space by using an injector on the edge of the holder hole in which the lens is fitted, so that the front and rear sides of the lens are filled with the silicone liquid. , so as to be symmetrically spaced apart from the injection hole with respect to the holder hole and communicate with both sides of the front and rear sides of the holder portion so that the silicone liquid injected into the space is filled in the space and then discharged to the outside. It is composed of a perforated discharge hole.

However, the existing underwater camera device moves the lens to adjust the focal length with the lens while the camera module is fixed, checks the camera screen, and adjusts the lens again to focus while adjusting the lens. When the focal length is changed due to the difference in the lens shape and silicone refractive index after curing is completed, it is difficult to accurately adjust the focal length of the lens.

In addition, the existing underwater camera device has a disadvantage in that maintenance is difficult because it is difficult to repair and take action in case of an electrical failure.
