Problems solved by technology

However, the environmental resistance of the compact camera has been improved by using the dome cover, but the advantages of the small size are sacrificed by the installation of the dome cover, and the original "flexibility of the compact camera" must be reduced.
[0004] A well-known dome cover has a spherical shape, and if a small camera is covered with a dome cover of this shape, the overall size becomes extremely large

Abstract

The present invention provides a dome-type camera and dome cover which reduce image quality degradation, caused by the optical properties of the dome cover, in image data generated on the basis of imaging light that has passed through the dome cover. In one embodiment of the present invention, the dome-type camera comprises a dome cover (11) and a camera unit (12). The dome cover (11) has a front surface (21) and a rear surface (22). The camera unit (12) includes an optical system (13) and an image capture element (14). The optical system (13) is arranged on the rear surface (22) side of the dome cover (11), and the image capture element (14) outputs image data on the basis of the imaging light received via the optical system (13). Of the front surface (21) and the rear surface (22) of the dome cover (11), at least the rear surface (22) has a non-spherical shape wherein the change in optical properties is continuous, at least in areas other than the top section t of the dome cover (11).

Description

technical field [0001] The invention relates to a dome camera and a dome cover, in particular to the technology related to the shape of the dome cover. Background technique [0002] The compact camera has high flexibility and applicability, and can be used for various shooting purposes regardless of the location. When shooting outdoors, it may be necessary to refrain from using it depending on the environment. For example, for a camera as a precision machine, wind, rain, snow, dust, sand, etc. are not necessarily preferred, so it is difficult to fully utilize the flexibility of a compact camera in such an environment. [0003] In order to be able to use the compact camera in various environments, the whole or part of the compact camera is usually covered with a transparent dome cover. However, the environmental resistance of the compact camera is improved by using the dome cover, but the advantages of the small size are sacrificed by the installation of the dome cover, and ...
