Summary of the invention
Technical problem to be solved by this invention is, a kind of image collecting device that has is provided, can effectively solve partial exposure excessively, the inhomogeneous and captured image blurring problem of exposure; A kind of acquisition method that is applied to image collecting device also is provided.
The technical scheme that technical solution problem of the present invention is adopted is, a kind of image collecting device comprises a sealing cover body, and the setting regions of cover body upside is set to transparent panel, in order to place subject; One image picking-up apparatus is fixed in the bottom side of cover body, and the alignment lens transparent panel of image picking-up apparatus is used to take the subject of placing on the transparent panel; At least one group of internal light source equipment is arranged on around the cover body upper inside walls relative with an image picking-up apparatus side of living in.Also comprise an automatic trigger equipment, be arranged on the outside of the upside transparent panel of cover body, and within the regional extent that subject can cover.
Further, the outside of described cover body upside transparent panel is placed with at least two baffle plates, is used for fixing subject.Described baffle plate is made of magnetisable material.Described cover body outer surface constitutes the external light source shielding device.The space sidewall that each limit of described image picking-up apparatus and cover body upside constitutes is the cover body inwall, and described cover body inwall constitutes the inner counter light device.
Further, described cover body one lateral surface is provided with automatic trigger switch, is used to control the Push And Release of automatic trigger equipment.
Further, between described automatic trigger equipment and image picking-up apparatus, be provided with a time-delay equipment, take when remaining static in order to the control subject.
The present invention also provides a kind of automatic triggering method that is applied to image collecting device, comprises the steps:
One image picking-up apparatus is provided;
One image acquisition region is provided, is used to place subject;
At least one group of internal light source equipment is provided, photographic light sources is provided;
One automatic trigger equipment is provided, is used to trigger image picking-up apparatus work;
When subject covered automatic trigger equipment, after subject remained static, this automatic initiating device triggered image picking-up apparatus and finishes shooting.
The invention has the beneficial effects as follows, adopt such scheme, the cover body of image collecting device sealing is as external light source shielding device and inner counter light device, in conjunction with the internal light source equipment of installing in the cover body, effectively solve over-exposed problem and because the uneven problem of partial exposure that the electric light source irradiation produces in subregion that the light source direct projection causes again.Automatically the design of trigger equipment makes image taking intelligent more.This device is easy to operate, and photographic images is clear.

Embodiment
Describe the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1, this device is made of sealing cover body, image picking-up apparatus, automatic trigger equipment and transparent panel.The setting regions of sealing cover body upside is set to transparent panel, and this transparent panel region composing images pickup area is in order to place subject.This setting regions is defined as the central area of sealing cover body upside, and this central area periphery is an one with other side of cover body.In the cover body upper edge and at the automatic trigger equipment of transparent panel arranged outside.And have two baffle plate (not shown)s to be placed on the transparent panel outside, being used for fixing the subject baffle position that is placed on image acquisition region can move according to the size of subject.Baffle plate is made by magnetisable material, can magnetic be adsorbed on the image collecting device surface.
Image picking-up apparatus is fixed in the bottom side of cover body, and the alignment lens transparent panel of image picking-up apparatus is used to take the subject of placing on the transparent panel.This image picking-up apparatus can be a digital camera, or video camera, and focal length can adopt automatic focus or fixed focal length pattern.If fixed focal length in the time of can taking, needs to adjust focal length and makes image reach the most clear state.
An end relative with image picking-up apparatus is provided with internal light source equipment around the cover body upper inside walls, is used to produce the light source of shooting needs.Internal light source equipment can be luminous always, and is luminous in the time of also can selecting to take.The position of internal light source will be evenly distributed on apart from around subject close together one end, guarantees that exposure evenly, prevents the regional direct reflective partial distortion that obtains image that causes that is taken.In the present embodiment, internal light source adopts the diode luminescence pipe or the fluorescent lamp of scattering to carry out light filling, better effects if.
Part outside the cover body transparent panel all is designed to opaque shape and prevents the light leakage.Therefore, the cover body outer wall constitutes extraneous shielded from light source device, is used to shield external light source, prevents that the brightness of taking is subjected to the influence of extraneous light.Space sidewall in image picking-up apparatus and each limit formation of cover body upside is the cover body inwall, described inwall constitutes the inner counter light device, non-smooth material by white is made, and makes photographic light sources can carry out sufficient diffuse reflection and shines subject again, further improves the effect of light filling.
Cover body one outer side edges is provided with mains switch and automatic trigger equipment switch, and this automatic trigger equipment switch is controlled the on off state of automatic trigger equipment.
Automatically be provided with a time-delay equipment between trigger equipment and the image picking-up apparatus, described time-delay equipment can be realized by an analog circuit, also can realize by a digital circuit, as single-chip microcomputer.Delay function also can pass to computer with signal by automatic trigger equipment and be realized by computer software.By time-delay equipment is set, guarantee that subject remains static to take.
In the present embodiment, automatically trigger equipment is a transducer, when subject enters the zone that is taken and is placed on the transparent panel, triggers transducer, and transducer sends the request of shooting to image picking-up apparatus and takes.Transducer can be infrared sensor, pressure sensor etc., and present embodiment adopts infrared sensor.
When using this device to take, subject is placed on the transparent panel, looks the size of subject and place baffle plate.After subject triggers transducer to run into baffle plate is stop motion, transducer passes to time-delay equipment with triggering signal, time-delay equipment is carried out after the time-delay order, triggering signal is passed to image picking-up apparatus takes, the subject of this moment remains static after time-delay, thereby has guaranteed the quality of photographic images.If image picking-up apparatus adopts video camera, principle also is the same.Video camera is the pattern of continuous acquisition, as long as the signal of taking is delivered to computer, that width of cloth image of getting then at that time gets final product.
For being not suitable for triggering automatically the object of taking, this device can be connected with computer, send the request of shooting by software keys that designs or keyboard and take.
The present invention efficiently solves the excessive or uneven problem of partial exposure of partial exposure, has abandoned the pattern that traditional use switching manipulation is taken.Easy to operate, photographic images is clear.Be fit to be applied to a plurality of fields such as office, library.
