Description
Technical field
The present invention relates to a kind of digital image register, be specifically related to a kind of digital image register based on the application of camera lens full figure field.
Background technology
The standard of the present general photo-sensitive cell of camera is 645 and 135 specifications, and 645 photo-sensitive cells are of a size of 44mm*33mm; 135 photo-sensitive cells are of a size of 36mm*24mm, and photo-sensitive cell shape is rectangle.The image field of existing camera lens is circular, is connected to the rectangle of circular image field in photo-sensitive cell is, and will cause like this waste of the effective image information of camera lens image field.In shooting process, need to consider patterning effect, increased the inconvenience in camera use procedure, post-processed space is less.Current video camera and monitor also possess above-mentioned shortcoming.
In view of this, need to invent the digital image register that a kind of full figure field information that is beneficial to post-processed gathers.
Summary of the invention
The digital image register that the object of the present invention is to provide a kind of full figure field information that is beneficial to post-processed to gather.
For achieving the above object, the technical solution used in the present invention is:
A digital image register for camera lens full figure field application, described photo-sensitive cell is circular photo-sensitive cell or square photo-sensitive cell.
As the present invention, further improve, the sensitive surface of described pentaprism is shaped as the outer square that lens transmit full figure field image light that is cut in.
As the present invention, further improve, described square photo-sensitive cell is the outer butt of accepting camera lens full figure field image capturing range.
As the present invention, further improve, described outer butt can be made digital compensation except the extraneous white space in full figure field and reduce.
As the present invention, further improve, described digital compensation reduction can utilize high-order interpolation to expand and color transfer theory is played up.
Compared with prior art, the beneficial effect that the present invention obtains is:
The present invention is owing to having adopted full figure field design, and traditional acquisition geometry of comparing has improved the utilance of existing camera lens image field, and image information collection capacity has reached full figure field and caught.In addition, square photo-sensitive cell is designed to accept the outer butt of camera lens full figure field circle, and can make digital compensation reduction, the further fuzzy field range that expanded to the extraneous white space of image field circle.Overcome and in shooting or photographic process, needed to consider the little shortcoming of patterning effect and post-processed space.

In the accompanying drawings: 1 photo-sensitive cell, 2 pentaprisms, 3 reflectors, 4 optical finders.
Embodiment
Below in conjunction with 1-3 and specific embodiment, the present invention is described in more detail.
As shown in Figure 1, a kind of camera based on the application of camera lens full figure field, this camera is based on guest being obtained to the improvement of 645D, camera comprises camera lens part, reflector 3, pentaprism 2, photo-sensitive cell 1 and optical finder, 4, its photo-sensitive cell 1 for radius be the circle of 28mm, the sensitive surface of its pentaprism 2 become improve before the square of 2.08 times of pentaprism sensitive surface area, other faces of pentaprism are done respective change.
Based on the improved camera of aforesaid way, directly the effective feeling light area of photo-sensitive cell 1 is become to 1.64 times before improvement.
The present invention can also do further improvement to photo-sensitive cell 1, it can be the length of side square that is 55mm, and can adopt digital dimmed compensation technique to compensating between the unexpected clear area of image field circle, the actual like this effective feeling light area obtaining becomes 2.08 times before improvement.
A Nikon D800 camera after the improvement of camera lens full figure field application, its photo-sensitive cell is that radius is the circle of 22mm, the sensitive surface of its pentaprism becomes the square of 2.17 times that improves front pentaprism sensitive surface area.Other faces of pentaprism are done respective change.
Based on the improved camera of aforesaid way, directly the effective feeling light area of photo-sensitive cell is become to 1.70 times before improvement.
The present invention can also do further improvement to photo-sensitive cell, it can be the length of side square that is 43mm, and can adopt digital dimmed compensation technique to compensating between the clear area outside image field circle, the actual like this effective feeling light area obtaining becomes 2.17 times before improvement.
A kind of video camera based on the application of the improved camera lens full figure of the HDR-PJ510E of Sony field, before improving, photo-sensitive cell is of a size of 1/3.91 inch, after improving, photo-sensitive cell is that radius is the circle of 3.25mm, and the effective feeling light area of the photo-sensitive cell after improvement is 1.96 times before improving.
The present embodiment can also be done further improvement to photo-sensitive cell, it can be the length of side square that is 6.5mm, and in camera, relate to computing system, and adopt digital fuzzy compensation technology to compensate the space outside image field circle, the actual like this effective feeling light area obtaining becomes 2.09 times before improvement.
Take 645 models as example, describe a kind of method for designing of the digital photography register based on the application of camera lens full figure field in detail:
Method one: rectangular cornerwise half 28mm of the 44mm*33mm of usining, as radius, obtains the circumscribed circle of 44mm*33mm, designs and produces the photo-sensitive cell large with resulting circumscribed circle etc.1.64 times of the photo-sensitive cell that now photosensitive area of photo-sensitive cell is 44mm*33mm.Pentaprism sensitive surface becomes the square of 2.08 times that improves front pentaprism sensitive surface area, and other faces of pentaprism are done respective change.
Method two: rectangular cornerwise half 28mm of the 44mm*33mm of usining is as radius, obtain the circumscribed circle of 44mm*33mm, using external diameter of a circle 55mm as the length of side, obtain the circumscribed square of circumscribed circle, design and produce the photo-sensitive cell large with resulting circumscribed square etc., the part of circumscribed square deduction inscribed circle, by digital fuzzy compensation, so both can obtain full figure field picture can also carry out fuzzy compensation reduction to the scenery outside image field, 2.08 times of the photo-sensitive cell that the photosensitive area that makes the photo-sensitive cell after improving is 44mm*33mm.Pentaprism sensitive surface becomes the square of 2.08 times that improves front pentaprism sensitive surface area, and other faces of pentaprism are done respective change.
The method realizes based on following principle:
The camera photo-sensitive cell of 645 models is rectangle, and camera lens is circular, and the image field that so just has partial lens is wasted, and cannot reach the effect of highly utilizing.As shown in Figures 2 and 3, during interior spreading in well-known circle is square, inscribed square 645 sides' area is maximum.But foursquare photo-sensitive cell still cannot reach the effect of full figure field application.Want to reach the effect that full figure field utilizes and photo-sensitive cell can be made to 645 side's circumscribed circles.In order to utilize more fully full figure field circumscribed circle can be extended, obtain the continuous square of 645 side's circumscribed circle, and square edge white space is carried out to mathematics fuzzy compensation, so just reached the utilance of photosensitive area.In the present invention, mathematics fuzzy compensation can utilize high-order interpolation to expand and color transfer theory is played up, and reaches the fuzzy imaging of white space.
For the camera of 645 models and 135 models, concrete photo-sensitive cell imaging area data are as table 1,
Table 1 645 and 135 and expansion imaging area
| Sequence number | Model | Limit/radius (mm) | Photosensitive area (mm 2） |
| 1 | 645 | 44*33 | 1452 |
| 2 | 645 sides | 39 | 1513 |
| 3 | 645 side's circumscribed circles | 28 | 2376 |
