Abstract

The utility model relates to an image-capture device which can scan documents. The utility model mainly includes an image-capture module group, and an optical scanning module group is added. The image-capture module group utilizes the function of array type inductors cooperating with a lens to shoot 3D images of objects. The optical scanning module group utilizes linear inductors cooperating with a lens to scan 2D images, for example, the images of documents. Thus the utility model enables the user to realize the dual effect of shooting 3D images of objects and scanning 2D images with one device.

Description

But the image capture unit of scanning document

The utility model relates to a kind of image capture unit, particularly a kind of image acquisition function that is combined with as 3D objects such as digital camera, video camera or V8, and the image capture unit of 2D image scanning function.

Now be used to absorb the product of image, be broadly divided into two big classes, a kind of image capture unit that is applicable to the 3D object, for example digital camera, video camera or V8 etc.; Another is applicable to the 2D device of image scanning, for example platform-type scanner etc.With digitized Image intake device, both action principles are roughly the same, with traditional platform-type scanner is example, it is equipped with substantially and includes: one in order to carry the glass platform (Window) and a ray machine module of object to be scanned (can be file or picture), in order to video conversion is become electric signal; The core of ray machine module then is an Image Sensor (Image sensor) and with the camera lens (Lens) of the correct focal imaging of the image of object in Image Sensor, Image Sensor (as CCD) has many image sensing pixels, along with each image sensing pixel is subjected to the difference of light intensity and gathers electric charge formation pressure reduction, then be converted into digital electric signal via analogy/digital quantizer (A/D Converter).

Wherein, the difference of both maximums is that the use of inductor, optical scanner are to utilize the function of linear response device to read the shadow file, are more suitable for scanning the 2D image; Image capture unit then is to utilize array inductor (as ccd array) to cooperate the function of camera lens to absorb the image of 3D object, and its resolution is low than scanner, and is not suitable for scanning the 2D image as this class of file.

So when the image of wanting to take the 3D object as the user needs scanning document again, then must prepare above two kinds of devices.

But the main order of the utility model is to provide a kind of image capture unit of scanning document, the image of available picked-up 3D object and scanning 2D image, and the user only needs a kind of device can have the function of scanning 2D image and 3D object image concurrently.

The technical solution of the utility model is: but a kind of image capture unit of scanning document, comprise an image capture module, this image capture module has an an array formula inductor and the camera lens in order to picked-up 3D image at least, it is characterized in that: more include an optical scanning module, this optical scanning module has a linear response device, a linear light sorurce generator, a transparent window at least, and in order to scan a camera lens of 2D image.

The utility model also can be realized by following technology: image capture unit more includes in order to store a mnemon of picked-up or scan-image, and wherein this mnemon is a memory card; This image capture unit more includes in order to avoid a prominent rib of transparent window and object to be scanned friction, is positioned at this optical scanning module outside, and contiguous periphery at transparent window.Image capture unit more includes a traverse gear, this traverse gear includes: in order to the motor of outputting power, and the gear set that is connected with motor, and a plurality of wheels that are exposed at image capture unit outward, and the interlock by gear set, drive the object surface that this image capture unit walking is being scanned.

For making the purpose of this utility model, structural attitude and function thereof that further understanding be arranged, existing conjunction with figs. and embodiment are described further:

Fig. 1, be structural representation of the present utility model.

Fig. 2, capture the synoptic diagram of remote image for the utility model.

Fig. 3, scan the closely synoptic diagram of image for the utility model.

Fig. 4, be the structural representation of the utility model second embodiment.

Fig. 5, be the structural representation of the utility model the 3rd embodiment.

Fig. 6, be the structural representation of the utility model traverse gear.

But, consist predominantly of an image capture module 10 and an optical scanning module 20 referring to the image capture unit 100 of Fig. 1,2, a kind of scanning document; Image capture module 10 is in order to the image (as a personage) of shooting 3D object 200, and optical scanning module 20 is with scanning 2D image (image of file 300 as shown in Figure 3).

As shown in Figure 1, image capture module 10 as Digital camera the same, mainly form by an an array formula inductor 11 (as ccd array) and a camera lens 12, adopt the capture of face type by array inductor 11, camera lens 12 is adjusted the function of the focal length and the depth of field, and is suitable for taking the image of 3D object 200.

Optical scanning module 20 then includes: a linear response device 21 (as Linear CCD), linear light sorurce generator 23 (as cold-cathode tube), transparent window 24 and camera lens 25 are formed, when transparent window 24 being relied on for example the surface of file 300 to move, just can be integrated into a planar 2D image by the line style 2D image that linear response device 21 scans gained one by one through file 300.In addition, because of optical scanning module 20 when the scanning 2D image, its transparent window 24 is surfaces of very close file, so can set up a prominent rib 22 that is adjacent to transparent window 24 peripheries in the outside of optical scanning module 20, to prevent producing friction between transparent window 24 and the file to be scanned 300, avoid the quality of transparent window 24 scratches or influence scanning.

Referring to Fig. 2, when user's desire is taken the image of 3D object 200, can utilize image capture module 10 to absorb the image of the 3D object 200 that will take.Otherwise if desire scanning 2D image (as scanning document 300), then as shown in Figure 3, the surface that utilizes optical scanning module 20 to move the file 300 through wanting to scan can be finished.

More including a mnemon 41 referring to Fig. 1, image capture unit 100, for example is the device of memory card etc.And absorb or scan the image of gained, just can be stored in the mnemon 41.

Referring to Fig. 4, another embodiment of the present utility model, more be provided with an infrared transmission unit 42 or a wireless radio transmission unit 43 (see figure 5)s, be sent in the treating apparatus that institute's tendency to develop send in order to image, for example the treating apparatus (not shown) of computer or the like absorb or scan gained.

Referring to Fig. 3, when the scanning document 300, must go movable image capture device 100 to finish the action of scanning by the user, but the speed that moves because of the user differs, can influence the 2D quality of image of file 300, so in another preferred embodiment of the present utility model, more be provided with a traverse gear 30, when the scan-image literal, can make the 2D image quality of scanning gained improve and stablize automatically with constant speed movement image capture unit 100.

Comprise a motor 31, gear set 32 and two wheels 33 referring to Fig. 6, traverse gear 30; Motor 31 is the source of power, with so that image capture unit 100 move; Gear set 32 connects motor 31, in order to transmit the power that motor 31 is exported; Wheel 33 is contained in the below of image capture unit 100, and with gear set 32 interlocks, when making scanning 2D image, image capture unit 100 automatically constant speed movement on the surface of file to be scanned 300.

But the image capture unit of scanning document provided by the utility model can provide the dual-use function of picked-up 3D image and scanning 2D image simultaneously, so can save substantial contribution, the use value of raising product improves the quality of absorbing 3D image and scanning 2D image.
