Abstract

The utility model discloses a star-light high-speed ball-type camera, which mainly solves the problems that in the traditional monitoring camera and under the condition without light assistance, the picture is not clear, and the visual range is small. The star-light high-speed ball-type camera is characterized in that a lens (2) is a high-throughput optical lens with the illumination intensity being lower than 0.0001LUX, the needed working illumination intensity of a CCD (Charge Coupled Device) is below 0.0001LUX, and the SNR (Signal to Noise Ratio) is more than 60 dB; and an arc opening (5) is arranged on the edge of a rotary drum (3) corresponding to the rotating track of a lens support (4). According to the star-light high-speed ball-type camera disclosed by the utility model, the high-throughput optical lens and a high-sensitivity CCD are adopted, the noise point of a night sight picture can be restrained by utilizing 3D (Three Dimension) digital noise reduction technology, and the picture which is finer and clearer can be obtained under the condition without the light assistance; and meanwhile, the visual angle of the lens is enlarged, and the visual range is large.

Description

Starlight high speed ball-shaped camera

Technical field

The utility model relates to a kind of rig camera, is specifically related to a kind of starlight high speed ball-shaped camera.

Background technology

TV monitoring system be utilize rig camera, the first-class equipment of making a video recording, camera lens is installed on the camera, place, all situation that target took place are kept watch in direct viewing on monitor.And can carry out record to the image information content of the place of being kept watch on, target biography through video tape recorder, be widely used in places such as bank, ATM, factory.Rig camera is that the light signal that the quilt of camera lens collection is taken the photograph body is become the signal of telecommunication, is delivered to system handles then, on monitor, demonstrates image.There is following defective in existing rig camera: 1. when using night; Because the lighting quantity deficiency of camera lens and the sensitivity of CCD are lower; Night vision image picture under the auxiliary condition of no light is unintelligible, needs generally that light is auxiliary just can see picture clearly.2. the camera lens visible angle is little, causes visual range little.

The utility model content

In order to overcome the existing rig camera deficiency that picture is unintelligible and visual range is little under the auxiliary condition of no light; The utility model provides a kind of starlight high speed ball-shaped camera; This starlight high speed ball-shaped camera adopts high pass light quantity camera lens and high-sensitive CCD; Utilize 3D digital noise reduction technology, suppress the noise of night vision image, under the auxiliary condition of no light, can obtain exquisiteness, picture clearly; Increased the camera lens visible angle simultaneously, visual range is big.

The technical scheme of the utility model is: a kind of starlight high speed ball-shaped camera comprises camera; Camera mainly is made up of tripod head frame, camera lens and CCD; Electronic rotary drum and lens bracket are installed on the tripod head frame, and cylinder can rotate for circumferential 360 ° relative to tripod head frame around self axis, and lens bracket radially is hinged on the cylinder end and can rotates relative to cylinder; CCD and camera lens are installed in the lens bracket; Described camera lens is the high pass light quantity camera lens that illumination is lower than 0.0001 LUX, and the required illumination of the work of described CCD is below 0.0001 LUX, and signal to noise ratio is more than 60dB; Rotary track corresponding position with lens bracket on the edge of cylinder is provided with the circular arc gap.

The utlity model has following beneficial effect: owing to take such scheme, camera lens adopts high pass light quantity camera lens, and the light that collects exceeds several times than common lens; Adopt the high-sensitive CCD of utmost point low-light (level) simultaneously; To obtain sound response to faint light, utilize 3D digital noise reduction technology, reduced the noise of night vision image; Night is when using, and can obtain fine and smooth, picture clearly under the auxiliary condition of no light; Lens bracket when revolution extreme position be in the circular arc opening position on the edge of cylinder, effectively increased visible angle, visual range is big.

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model.

1-tripod head frame among the figure, 2-camera lens, 3-cylinder, 4-lens bracket, 5-gap.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further:

By shown in Figure 1; A kind of starlight high speed ball-shaped camera comprises camera, and camera mainly is made up of tripod head frame 1, camera lens 2 and CCD, and electronic rotary drum 3 and lens bracket 4 are installed on the tripod head frame 1; Cylinder 3 can around self axis relative to tripod head frame 1 circumferential 360 ° rotate; Lens bracket 4 radially is hinged on cylinder 3 ends and can rotates relative to cylinder 3, and CCD and camera lens 2 are installed in the lens bracket 4, and described camera lens 2 is lower than the high pass light quantity camera lens of 0.0001 LUX for illumination; The required illumination of the work of described CCD is below 0.0001 LUX, and signal to noise ratio is more than 60dB; Rotary track corresponding position with lens bracket 4 on the edge of cylinder 3 is provided with circular arc gap 5.Owing to take technique scheme, camera lens 2 adopts high pass light quantity camera lens, and the light that collects exceeds several times than common lens; Adopt the high-sensitive CCD of utmost point low-light (level) simultaneously; To obtain sound response to faint light, utilize 3D digital noise reduction technology, reduced the noise of night vision image; Night is when using, and can obtain fine and smooth, picture clearly under the auxiliary condition of no light; Lens bracket 4 when revolution extreme position be in circular arc gap 5 places on the edge of cylinder 3, effectively increased visible angle, visual range is big.
