Problems solved by technology

Therefore, when imaging at a wide oblique angle and a direction close to the horizontal direction, although the partial light-shielding filter 104 can be provided in the insertion position, it is impossible to control the amount of insertion in response to the monitoring direction or the monitoring object, resulting in, for example, excessive Darkness, etc., which is reflected in the inability to obtain the most appropriate image, for example

[0091] like figure 1 As shown, the camera device 10A according to the first embodiment is, for example, attached to a ceiling surface 11 as another member attachment surface, and can be used as a surveillance camera that can monitor a lower area 360 degrees from the ceiling surface 11 .

[0092] In the following description, it is considered that the ceiling surface 11 is the upper side, and the opposite side of the ceiling surface 11 is the lower side.

[0093] The camera device 10A has a main body (camera main body) 20 that can be attached to the ceiling surface 11 . The main body 20 has: a disc-shaped base 21 attached to the ceiling surface 11 ; a substantially cylindrical receiving portion 22 attached to the underside of the base 21 and a light-transmitting hemispherical cover 23 that covers the opening 221 of the accommodating portion 22 .

[0094] like figure 2 As shown, the internal mechanism 30 is housed in the main body 20 . The internal mechanism 30 accommodate...

[0137] Next, the camera device according to the second embodiment will be described.

[0138] The same reference numerals and symbols are applied to the same parts as those of the camera device 10A in the first embodiment, and repeated descriptions will be omitted.

[0139] like Figure 11 As shown, in the camera device 10B in the second embodiment, the light shielding plate portion 50B has a pair of (sub) light shielding plates 571 and 572 (an upper light shielding plate and a lower light shielding plate). The two light shielding plates 571 and 572 are separated from each other by a distance larger than the outer diameter of the lens 41 , and the opening 58 is provided between the two light shielding plates 571 and 572 .

[0140] Therefore, if Figure 12A As shown, in the state where the light-shielding ratio M=0, the entire front portion of the lens 41 is exposed forward from the opening 58 .

[0141] At the same time, the light-shielding plate portion 50B is lowered (at ...

[0151] Next, the camera device according to the third embodiment will be described.

[0152] In the camera apparatuses 10A and 10B in the first and second embodiments, the visor portions 50A and 50B are moved to partially block the light of the lens 41 to prevent the images from overlapping, thereby obtaining the most appropriate images.

[0153] In the camera device 10C in the third embodiment, the structure of the visor portions 50A and 50B is used to realize the function of protecting privacy.

[0154] like Figure 14 As shown, in the camera device 10C of the third embodiment, the third motor 55 is controlled (refer to Figure 3 to Figure 5 ) to move the visor 51 to cover the entire front sphere of the lens 41 to be hidden. In this way, when the light blocking plate 51 is in a position to cover the entire front sphere of the lens 41 to be hidden (light blocking ratio M=100%), the privacy of the person to be imaged projected on the camera unit 40 can be protected, and It ...

Abstract

A camera apparatus includes: a cover that has transparency; a rotatable camera unit that is provided inside the cover; a shade plate portion that includes a shade plate capable of partially shading light incident on the camera unit, wherein a position of the shade plate is rotatable; a control unit that is configured to control rotation of the camera unit and the position of the shade plate; and a memory that stores posture information including an imaging direction of the camera unit and positional information on the shade plate in association with each other. The control unit controls a direction of the camera unit based on the posture information stored in the memory and controls the position of the shade plate based on the positional information on the shade plate stored in the memory.

Description

technical field [0001] The present invention relates to a camera device having a function of rotating a camera lens in a pan direction or a tilt direction, and a method of controlling the camera device. Background technique [0002] In the related art, in a camera apparatus such as a surveillance camera, it is generally accepted that a camera lens is rotated in a pan direction and a tilt direction to capture an image (for example, refer to Patent Document 1). [0003] like Figure 17 As shown, the dome-type camera 100 disclosed in Patent Document 1 includes a hemispherical dome cover 101 . Inside the dome cover 101, a lens unit 103 having a camera lens 102 is accommodated. [0004] In the dome type camera 100, a pan motor and a tilt motor are provided. The lens unit 103 is rotatable in the pan and tilt directions. [0005] In this dome-type camera 100, in order to prevent vignetting when an image is captured in a direction with a wide tilt angle (a direction close to the ...
