Abstract
The present invention relates to a kind of device and method of auxiliary photo-taking formula scanner focusing.There is the low success rate of problem of auto-focusing in the case of comparison of light and shade is unconspicuous between background scanned for the photo taking type scanner that auto-focusing is carried out using focusing detection method, apparatus of the present invention are made up of focusing plate, axostylus axostyle and hinge, by setting chequered with black and white striped on focusing plate, and pass through rotation and slide hinge, make the comparison of light and shade that distinctness is formed around scanned, so as to improve focusing success rate.The step of the inventive method is given using apparatus of the present invention.
Description
Technical field
The invention belongs to optical field, is related to a kind of device of auxiliary photo-taking formula scanner focusing.
Background technology
Photo taking type scanner is to scanned with digital camera（Such as books）Take pictures the equipment to form digital picture.At it
In each scanning process, digital camera usually requires to carry out auto-focusing, and much carries out auto-focusing using focusing detection method,
But in some cases, due to the scanned comparison of light and shade unobvious between background, it can make it that auto-focusing success rate is low,
So as to influence scan efficiency.
The content of the invention
In view of the above-mentioned problems, the invention provides a kind of device of auxiliary photo-taking formula scanner focusing.
The device is using the principle that light and shade contrast is improved around scanned come auxiliary focusing, and it is by focusing plate, axle
The three parts such as bar and hinge form.
Plate of focusing is a rectangle plank, has chequered with black and white striped above, to form a sharp contrast between striped.
Focusing plate is connected by hinge with axostylus axostyle, can be rotated up perpendicular to axostylus axostyle side, to be closely attached on scanned mounting table
Face, and can be in axostylus axostyle side's upward sliding, so as to the scanned edge that aligns.
Axostylus axostyle is a straight-bar for being used for positioning focusing plate, is black.
Hinge is used for connecting focusing version and axostylus axostyle, is black, and can be slided with focusing plate along axostylus axostyle.
It is upper using, if left and right camera lens is to scanned left and right two sides（Such as the left and right page two of book）It is scanned, then
The device needs 4 blocks of focusing plates, by slide hinge, makes upper and lower side of the focusing plate respectively with scanned left and right two sides
Along alignment, and axostylus axostyle is placed in the medium line on scanned left and right two sides（Such as spine）Under.It is if single-lens to scanned one
Face is scanned, then the device needs 2 blocks of focusing plates, by slide hinge, make focusing plate respectively with scanned both sides
Along alignment, and axostylus axostyle is positioned over scanned side.
The positive effect of the present invention is：The focusing success rate of photo taking type scanner can be improved.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention, wherein：1- focusing plates；2- axostylus axostyles；3- hinges.
Embodiment
The specific embodiment of the present invention is elaborated below.
As shown in Figure 1, a kind of embodiment of apparatus of the present invention includes：Focusing plate 1, axostylus axostyle 2 and hinge 3.
Focusing plate 1 shares 4 pieces, is 40 centimetres of 10 cm x per block size using plastic material, thickness is 0.1 centimetre, often
For block parallel to its chequered with black and white striped of short side direction air brushing, the width per striped is 0.5 centimetre.Axostylus axostyle 2 is 0.1 li of diameter
Rice, the black steel wire that length is 55 centimetres.Hinge shares 4, and every is black spring wire, and every wire diameter is 0.05 li
Rice, external diameter are 0.5 centimetre, and number of total coils 3 is long 3 centimetres.
For every block of focusing plate 1 in the centimeters of edge 0.2 away from its short side, it is 1 li to be provided with spacing between a diameter of 0.1 centimetre, hole
Multiple holes of rice.Each position as shown in accompanying drawing 1 of hinge 3 is penetrated on each focusing plate 1 hole opened, and be inserted in axostylus axostyle 2, all
Focusing plate 1, axostylus axostyle 2 and hinge 3 connect together.Focusing plate 1 can be rotated up perpendicular to the side of axostylus axostyle 2, be swept to be closely attached on
The placed mesa of thing is retouched, and, so as to the scanned edge that aligns, then, can be focused black on plate 1 in axostylus axostyle side's upward sliding
Informal voucher line just improves comparison of light and shade around scanned, and this can auxiliary focusing.
Size in the present embodiment can change according to scanned size；Material can be according to firm and solid journey in the present embodiment
Spend to change, plate 1 of such as focusing can be art post paperboard, and axostylus axostyle 2 can be plastic bar, and hinge 3 can be nylon wire；Focused in the present embodiment plate
1st, the quantity of hinge 3 can determine according to the quantity of surface to be scanned, if left and right camera lens is to scanned left and right two sides（Such as book
Left and right page two）It is scanned, then has 4 blocks of focusing plates 1 and 4 hinges 3, if single-lens sweep to scanned one side
Retouch, then have 2 blocks of focusing plates 1 and 2 hinges 3.
Using above-mentioned specific embodiment shown device, the method for auxiliary photo-taking formula scanner focusing is following steps：
（1）Focusing plate 1, axostylus axostyle 2 and hinge 3 are close on scanning table top；
（2）Place scanned above the auxiliary photo-taking formula scanner focusing mechanism；
（3）Axostylus axostyle 2 is placed at the medium line on scanned left and right two sides；
（4）The slide hinge 3 on axostylus axostyle 2, it is close to burnt plate 1 scanned；
（5）Start photo taking type scanning.
One embodiment of the present of invention is described in detail above, but the content is only the preferable implementation of the present invention
Example, it is impossible to be considered as the practical range for limiting the present invention.All equivalent changes made according to the present patent application scope and improvement
Deng, all should still belong to the present invention patent covering scope within.
