Abstract
The utility model discloses a multispectral optical filter switching apparatus used for a camera. The multispectral optical filter switching apparatus used for the camera includes a pedestal, a rotating disc, a transmission mechanism and optical filters. The pedestal has a photosensitive window; the rotating disc has a disc structure with straight teeth at the periphery, the rotating disc is mounted on the pedestal through a rotating shaft and can rotate circling the axial lead of the rotating shaft; four optical filters are disposed, an optical filter mounting disc is provided with four loopholes which correspond to the photosensitive window by rotating the rotating disc, and the optical filters are fixed at the loopholes through supports; and the transmission mechanism includes a deceleration motor which drives the rotating disc to rotate through cooperation of a worm and the straight teeth at the periphery of the rotating disc. The multispectral optical filter switching apparatus used for the camera has a plurality of optical filters, and can be used for shooting in different environments, so as to satisfy people' demands; and the assembly is convenient and the reliability is high.
Description
Technical field
The utility model relates to camcorder technology field, relates in particular to a kind of multi-spectrum filter sheet switching device shifter for video camera.
Background technology
The imaging components and parts CCD of video camera or CMOS can see the light of most wavelength, wavelength coverage is between 200nm-1000nm, according to imaging need to before its imaging components and parts, install corresponding spectral filter, can improve the image quality of video camera under varying environment light.On existing market, video camera all adopts two switching device of optical fiber, and the optical filter of two kinds of different spectrum can only be installed, and generally can only adapt to two kinds of light environments, thereby cannot normally clearly make a video recording in the place of circumstance complication; Cannot meet the shooting requirement that people increase day by day to video camera.
Summary of the invention
For prior art above shortcomings, the purpose of this utility model is just to provide a kind of multi-spectrum filter sheet switching device shifter for video camera, has multiple optical filter, can under different environment, make a video recording, thereby meet people's demand; Easy to assembly, reliability is high.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of multi-spectrum filter sheet switching device shifter for video camera, is characterized in that: comprise base, rotating disc, gear train and optical filter; Described base has photosensitive window, and described rotating disc is disc structure, and its periphery has straight-tooth, and this rotating disc is arranged on base and can be rotated by axial line around the shaft by rotating shaft; Described optical filter is 4, offers 4 light holes in optical filter mounting disc, rotates rotating disc, light hole can with photosensitive window over against, described optical filter is fixed on light hole place by support; Described gear train comprises reducing motor, and this reducing motor rotates with the driven rotary dish that coordinates of rotating disc periphery straight-tooth by worm screw.
Further, on described base, also there is photoelectrical position sensor, near 4 tablet filters, be provided with position encoded hole, when near position encoded hole optical filter and photoelectrical position sensor position over against time, this optical filter position just in time with photosensitive window position over against.
Further, described rotating disc is arranged in rotating shaft by bearing; Rotating disc is rotated more smooth and easy, thereby global reliability is higher.
Compared with prior art, the utility model has the advantage of: simple in structure, practicality is high; 4 kinds of optical filters can be installed, by the optical filter of different spectrum is installed, can adapt to the shooting under multiple ambient light, as used cutoff filter daytime, restore true colour; Use full spectral filter night, make camera image sensor make full use of all light, thereby greatly improved low according to performance; Greasy weather is used Penetrating Fog optical filter, effectively improves image quality and image definition; While carrying out laser auxiliary lighting, use the narrow-band spectrum optical filter of respective wavelength, effectively suppress the light of other wavelength, guarantee the effective lighting of laser, highlight target detail; Meanwhile, directly adopt reducing motor as gear train, assemble conveniently, and reliability is higher.
