Point can also form the picture point that eyes acceptable is more visible, all scenery of the front and back of this plane away from
From the depth of field Δ L being called camera.
When the parallel light of optical axis injects convex lens, preferable camera lens should be all of light-ray condensing on one point after, then
Come with taper diffusion, a bit of these all light of gathering, just it is called focus.
Before and after focus, light starts to assemble and diffusion, and the image of point becomes fuzzy, forms a circle expanded, this
Individual circle is just called blur circle, a diameter of σ of blur circle.
In the middle of reality, the image viewing and admiring shooting is (such as to project, zoom into photo etc.) in some way to observe
, the image that human eye is experienced has the biggest relation with enlargement ratio, projector distance and viewing distance, if blur circle
Diameter σ more than the distinguishing ability of human eye, the fuzzy of actual video generation is unidentified.This can not
The blur circle of identification is known as allowing blur circle (permissible circle of confusion).Focus forward and backward respectively
One is had to allow blur circle.
On the basis of holding photographing unit photographer, from focus to allow nearby blur circle distance front depth of focus J1, from Jiao
Point allow to a distant place distance of blur circle rear depth of focus J2, front depth of focus J1 and rear depth of focus J2 sum are depth of focus J.
When shooting, regulate camera 141 camera lens, make the mistake of the scenery blur-free imaging of distance camera 141 certain distance
Journey, is called focusing, the point at that scenery place, referred to as focusing, because " clearly " is not a kind of absolute concept, so,
Before focusing, the imaging of the scenery in (near camera 141), rear certain distance can be clearly, this antero-posterior extent total
With, just it is called depth of field Δ L, as long as the meaning is the scenery within the scope of this, can clearly photograph.Depth of field Δ L's is big
Little, first relevant with lens focus f, the camera lens of focal distance f length, Δ L is little for the depth of field, and the short camera lens depth of field Δ L of focal distance f is big.Secondly, scape
Deep Δ L is relevant with aperture F, and aperture F the least (numerical value is the biggest, and the aperture of the such as F16 aperture than F11 is little), depth of field Δ L are more
Greatly；Δ L is the least for the depth of field for aperture F the biggest (numerical value is the least, and the aperture of such as F2.8 is more than F5.6).Secondly, front depth of field Δ L1 is little
In rear depth of field Δ L2, say, that after exact focus, before focusing, the scenery in the shortest distance can clearly become
Picture, and the scenery in the longest segment distance after focusing, be all clearly.
The imaging space degree of depth of eye can be referred to as simultaneously by the most clearly spatial depth, be i.e. depth of field Δ L.
The front depth of field
The rear depth of field
Depth of field Δ L=Δ L1+ Δ L2.
