Abstract
The present invention discloses a sub-frame image splicing method adopting several low-resolution small images and making them pass through the process of multiple projection image-forming treatment to form of complete high-resolution large frame image. It is characterized by that firstly, the periphery of every sub-frame image is passed through the process of image element brightness asymptotic treatment, and when splicing sub-frame images, the peripheries between the sub-frame images must be mutually overlapped and spliced, so that said invention can remove the bright line or dark line produced between sub-frame images so as to form a good, large and integrated image.
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 resolving power 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 Jap.P. JP03041868 discloses a kind of method. photosensitive material is under the driving of x axle y axle two-dimensional motion mechanism, LCD is aimed at the zones of different on the photosensitive material at every turn, 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 hook-up 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 marginarium all multiplies each other with a luminance factor, and luminance factor is extremely diminished by near far gradually with the distance in decentering district, and its Changing Pattern is linear or non-linear arbitrary curve to be changed.Be divided into 100 pixels as the marginarium that will divide images, the luminance factor of each pixel extremely far is decided to be 99%, 98%, 97%, 96% by the decentering 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 decentering 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 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 decentering district, and the width of marginarium 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 marginarium 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 marginarium 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 marginarium other each point of lap is the weighted mean values of two images after the respective points dislocation, splicing place sharpness slightly reduces, but can not make image tangible concealed wire occur.Reduced 1% 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 marginarium other each point of lap is the weighted mean values of two images after the respective points dislocation, splicing place sharpness 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 marginarium 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+1, and the brightness of marginarium 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 marginarium 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 that plural low resolution is divided images with the image processing of high resolving power view picture earlier;
2. will divide the edge district of images to carry out the pixel brightness gradual change by electronic circuit, software program or brightness trimmer handles;
3. display, camera lens and imaging surface do relative motion or remain static, each zones of different projection imaging of aiming at imaging surface, make every width of cloth divide images to splice one by one, form the big images of view picture high resolution, during as the framing image connection, should make the overlapped splicing in marginarium between the branch images.
4. the width of above-mentioned marginarium is 1～65536 pixel, and imaging surface is photosensitive material or screen, and the brightness trimmer is film, LCD plate, and dividing images is fritter image or line segment.
