Abstract
The present invention discloses a method for splicing split images, which makes a plurality of small images with low resolution imaged in a projection mode for many times to form a complete image with high resolution and a large equiamplitude surface. The method is characterized in that image element brightness gradation processing is carried out to the circumferential marginal zone of each of split images. When the split images are spliced, the marginal zones among the split images are interlapped and spliced. The method can be used for eliminating the occurrence of bright lines of dark lines among the split images, so the integral effect of the formed image with the equiamplitude surface is favorable.
Description
The invention belongs to image and show the imaging field.
In order to write down or to show a panel height resolution entire image, can adopt several low resolution small image, make their multiple projections imagings, to form a complete high-resolution large area image.
It is with projection lamp the low-resolution image on the LCD to be projected imaging on the photosensitive material surface by camera lens that Japan Patent JP03041868 discloses a kind of method.Photosensitive material is under the driving of x axle y axle two-dimensional motion mechanism, and LCD is aimed at the zones of different on the photosensitive material at every turn, and framing exposure one by one finally forms complete significantly high-definition picture on photosensitive material.
Because this patent is with fritter picture frame direct splicing, in actual applications, the error of display and camera lens can make the framing image edge produce the convex-concave distortion.Mechanical device also can make the branch images produce position deviation.This all can cause at the splicing seams place of adjacent minute images and produce tangible bright line or concealed wire.Shown in Fig. 3 a, two fens images of A, B are desirable splicing states.When causing owing to above-mentioned two kinds of reasons that the distance between the images was zoomed out in two minutes (B, C among Fig. 3 a divide images), then the imaging surface between two fens images concealed wire (B, the C that see Fig. 3 b divide the images joint) occurs because of failing exposure.When cause two fens distances between the images to be pushed (C, D among Fig. 3 a divide images) when near owing to above-mentioned two kinds of reasons, then the imaging surface lap between two fens images produces bright line (C, the D that see Fig. 3 b divide the images joint) because of double exposure.
The objective of the invention is to overcome above-mentioned prior art weak point, provide a kind of and can eliminate divide bright line or the concealed wire that occurs between the images, realize many framings image connection after, can form the good framing image connection method of big images whole structure.
The objective of the invention is to realize: 1. before the framing image connection, divide images to carry out the edge gradual change to every width of cloth and handle by following measures.The method of handling one is not deal with by electronic circuit or the software program pixel brightness with every width of cloth framing image center district, keeps former brightness value.Its edge district does the gradual change of each pixel brightness and handles, and each pixel that is about to the marginal zone all multiplies each other with a luminance factor, and luminance factor is extremely diminished by near far gradually with the distance in decentre district, and its Changing Pattern is linear or non-linear arbitrary curve to be changed.Be divided into 100 pixels as the marginal zone that will divide images, the luminance factor of each pixel extremely far is decided to be 99%, 98%, 97%, 96% by the decentre district near ... 1% (seeing Fig. 4 c); The 2nd, manufacture a width of cloth or the above brightness trimmer of a width of cloth earlier by electronic circuit or photograph, its center transparency is the highest, and the transparency in edge, center district is extremely reduced by near far gradually with the decentre district, then the brightness trimmer is placed light path near display or imaging surface place, when carrying out the imaging of framing image projection again, the pixel in framing image edge district is subjected to the modulation of each point light transmittance on the brightness trimmer to make the center pixel brightness of per minute images keep former brightness value, the brightness in its edge district is extremely diminished by near far gradually with the distance in decentre district, and the width of marginal zone is 1～65536 pixel.2. divide images to carry out lap splice every width of cloth then.
Following three kinds of situations can appear when carrying out the framing image connection by above-mentioned measure: the one, and desirable splicing state, do not occur between two fens images anamorphose and or position deviation, the pixel brightness when then the i in the lap splice marginal zone is capable is two fens images brightness sum (seeing A ' and B ' minute images among Fig. 4 c) in this row respective point.Two is that two width of cloth divide images in the capable splicing marginal zone of j when overlapping, anamorphose or position deviation appear between the image and when making two fens images being zoomed out, then reduce at the j+1 of one fen images and the locational pixel brightness of another minute images j+n, and the brightness of marginal zone other each point of lap is the weighted averages of two images after the respective points dislocation, splicing place definition slightly reduces, but can not make image tangible concealed wire occur.Reduced l% as the j+1 of B ' minute images among Fig. 4 d and the locational pixel brightness of C ' minute images j+100.And the brightness of marginal zone other each point of lap is the weighted averages of two images after the respective points dislocation, splicing place definition slightly reduces, but can not make the image connection place tangible concealed wire occur, sees stack place between the B ' of Fig. 4 a, b and C ' minute images.Three is that two width of cloth divide images in the capable splicing marginal zone of k-1 when overlapping, occur anamorphose or position deviation between the image and two fens images are pushed when near, then increase slightly at the k of one fen images and the locational pixel brightness of another minute images k+l, and the brightness of marginal zone other each point of lap also increases slightly, jump in brightness can not occur, the image connection place tangible bright line can not occur.Increase slightly as the k of C ' minute images among Fig. 4 e and the locational pixel brightness of D ' minute images k+1, and the brightness of marginal zone other each point of lap also increases slightly, jump in brightness can not occur, see the C ' of Fig. 4 a, b and spliced stack place in D ' minute between the images tangible bright line not occur.
Detailed step of the present invention is:
1. be plural low resolution framing figure with the image processing of high-resolution view picture earlier
Resemble;
By electronic circuit, software program or brightness trimmer will divide images around
The marginal zone is carried out the pixel brightness gradual change and is handled;
3. display, camera lens and imaging surface do relative motion or remain static then,
It is each to divide every width of cloth of the shown low resolution of display images to pass through camera lens
Aim at the zones of different projection imaging of imaging surface, make every width of cloth divide images to piece together one by one
Connect, form the big images of view picture high-resolution.During as the framing image connection,
Should make the overlapped splicing in marginal zone between the branch images.
4. the width of above-mentioned marginal zone is 1～65536 pixel, and imaging surface is a photosensitive material
Or screen, the brightness trimmer is film, LCD plate, it is little dividing images
Piece image or line segment.
