Description
Technical field
The utility model relates to a kind of filming apparatus, is specifically related to a kind of safety monitoring and intelligent transportation photography or shooting (detecting or monitoring) high definition of taking based on sensor devices such as CCD or CMOS in field or differentiation sensitization digital filming apparatus of SD of being mainly used in.
Background technology
Traditional filming apparatus integral light-transmitting or whole optical filtering formula (as visible or infrared light) sensitization, due to its single photobehavior, when in picture, zones of different exists different exposures to require, just can not meet the emphasis sensitization requirement of specific region.
There is high light overexposure and when another regional exposure deficiency, improve exposure or reduce exposure and all can bring the more serious problem in another region in a certain region in picture.
Summary of the invention
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of zones of different is carried out to differentiation exposure-processed, and in same width picture, people is the step sensitization digital filming apparatus of building the multiple exposure effects such as dark space and clear zone or dark space, inferior clear zone and clear zone and color effect.
For achieving the above object, the utility model provides following technical scheme: a kind of differentiation sensitization digital filming apparatus for safety monitoring or intelligent transportation photography and shooting field, comprises housing, is arranged on the sensor devices in housing and is arranged on the camera lens before sensor devices; Before described sensor devices, be provided with the step filter glass for filtering different wavelength range that covers sensor devices.
By adopting technique scheme, abandoned the single sensitization setting of traditional camera, adopt step filter glass to carry out differentiation exposure to sensor devices, so just can in same width picture, obtain the image of different exposures and different color effect.In safety monitoring and intelligent transportation photography and shooting, during typically as shooting road driving automobile, because car plate, vehicle body and occupant have significant difference to the requirement of exposure, when filming apparatus or light are during in vehicle front, because the orienting reflex characteristic of car plate is in strong reflection object, easily produce the phenomenon of overexposure; And occupant is due to the obstruct of glass for vehicle window, in low echo area, tend to owe to expose to the sun.Use technique scheme, at car plate and headstock position, set up dark space (infrared ray as whole in filtering), avoid car plate overexposure, for the identification of the number-plate number and the identification of car plate color, provide reliable foundation; Simultaneously at vehicle body and front windshield place, clear zone (as a filtering part infrared ray) is set, so just avoided environment inside car owe expose to the sun, just occupant can cover all at one glance.Two parts form difference like this, and each takes what he needs, and the basis of picture and convenience are all very strong.
The utility model can further arrange: described step filter glass at least comprises the Yu Hui dark space, bright district that is respectively horizontally set, and described grey dark space is placed in the bottom in bright district.
By adopting technique scheme, while being used for taking mobile object (as automobile), utilize the corresponding different photosensitive regions of step filter glass, can do differentiation exposure to environment, scene, object, sign and personnel, better the personnel of different distance, different illumination conditions and different reflection characteristics or object are implemented to take and effectively identify.
The utility model can further arrange: described step filter glass also comprises and be horizontally set Zhong Guang district, and described Zhong Guang district is placed between described bright areas ash dark space.
By adopting technique scheme, while being used for taking mobile object (as automobile), utilize the corresponding different photosensitive regions of step filter glass, can do differentiation exposure to environment, scene, object, sign and personnel, further better the personnel of different distance, different illumination conditions and different reflection characteristics or object are implemented to take and effectively identify.
The utility model further arranges: described step filter glass is set to gradual change type filter glass.
By adopting technique scheme, adopt gradual change type filter glass to carry out selectivity to sensor devices and block exposure, so just can in the same width picture of the serious skew of high light and low light, obtain the image of exposure balance.This picture both can utilize the light district of progressive lens to expose to low light region, can utilize again the relatively dark district of filter glass to expose to highlight area, thereby obtained the image of a secondary exposure relative equilibrium.In safety monitoring and intelligent transportation photography and shooting, typical as while taking road driving automobile, because car plate and vehicle body have different reflection efficiencies, often there will be the situation that car plate overexposure or vehicle body owe to expose to the sun when night lights illumination (particularly); Use technique scheme, problem has just been readily solved.
The utility model further arranges: described step filter glass is set to visible ray filter glass or infrared ray filter glass.
By technique scheme, bring into play more fully the flexibility of this filming apparatus, the step filter glass of different wavelength range can be set according to different shot objects and different photographing requests.
The utility model further arranges: described step filter glass is arranged in described housing, and is placed between described sensor devices and camera lens.
By adopting technique scheme, the image that this filming apparatus is absorbed is meticulousr careful and clear, prevents step filter glass dust stratification, ponding or damage simultaneously, and also can need to change according to actual conditions.
Below in conjunction with accompanying drawing, the utility model is further described.
