Specific implementation mode
In order to make the objectives, technical solutions and advantages of the present invention clearer, With reference to embodiment and joinAccording to attached drawing, the present invention is described in more detail.It should be understood that these descriptions are merely illustrative, and it is not intended to limit this hairBright range.In addition, in the following description, descriptions of well-known structures and technologies are omitted, to avoid this is unnecessarily obscuredThe concept of invention.
The content that is shown of video of word, image and continuous multiple frames image composition, be by the acquisition of human eye byAcquired in people, for example be printed upon paper-made advertising, books or be shown in film on electronic media, TV etc..Due to point of human eyeResolution is limited, and the resolution ratio for improving printing or display unlimitedly is not necessarily to.For example, someone calculated,Minimum resolution distance under the sighting distance of 25cm is not 0.1mm.Higher resolution ratio, for example, will display content more smaller than 0.1mm,It cannot be captured by human eye.Therefore, there are certain limits for the content that can be shown on unit area.Therefore, Wo MenwuOne novel is compressed in video human-readable on the scraps of paper of a very little, can not to have larger data amount by one by methodPrint matter browses on a small scraps of paper for everybody.Fiche can also be realized print to one section of video in some senseOn one pictures.For example, using fiche technology, all picture frames in one section of video are reduced frame by frame and print to oneOn film, the purpose on a sheet of paper by video printing can also be realized.However, fiche, is the production for simulating the calculating epochObject, the printing and reading of film are required for special equipment, and fiche is simply to contract to original imageIt is small, larger information loss can be caused in micro process and reading process.Fiche is only applicable to analog imageAcquisition and diminution.Fiche technology directly can not carry out compression processing to digital content.And the year extremely universal in digitlizationGeneration, how by digitized content, including text, text+image blend, computer installation procedure, music, the image after codingOr video data, and other computer datas in addition to music, video, image, text, it prints on a sheet of paper, orIt is shown on the page of electronic curtain, is that the prior art does not solve the problems, such as fully.
For the ease of the propagation of information, it would be desirable to which a kind of new technology, the technology can realize following purpose：
(1) by video or other need the digital information that multiframe or multiple pages could be presented, including novel, textbookDeng printing to and be transmitted and read on a pictures；
(2) include the picture of above-mentioned digital content, there can be high-resolution photographic camera to obtain simultaneously by mobile phone etc.Identify content therein；
It (3), may be by shadows such as light, camera shrewdness components accuracies because photographic camera is when reading pixel map informationIt rings, will produce certain reading error, therefore when digital content is printed to a pictures, certain fault-tolerant machine can be providedSystem.
In the present invention, the mode of non-image digital content image is showed, purpose is not configured to the sight of human eyeIt surveys, in other words, the content not instead of image itself which really transmits, in order to more easily by number as much as possibleIt is visible that word content is converted into human eye acquired in other daily common equipment such as mobile phone, then by these common equipmentForm.A kind of common form by digital information image conversion is Quick Response Code.But the purpose of the present invention is different from existing Quick Response Code.One main usage of Quick Response Code is to be presented brief text (such as URL) or identity information coding in quick response code formIn image, information content is no more than the information content that human eye can identify in the image of same area, accordingly even when with relatively low pointThe camera of resolution can also quickly and accurately identify the content of Quick Response Code.It is generally believed that the pixel density of an image is in every EnglishWhen very little possessed number of pixels is more than 300 or more, the limit that human eye can be differentiated is had reached.In our inventionIn, in order to which on the area of certain size, more information content that transfer ratio human eye can be read use figure as high as possibleAs printing or display resolution.For this purpose, we are by minimum printing or display, rate is set as the pixel that per inch is possessed respectivelyNumber (Pixel Per Inch) is not less than 1200 (1200PPI).Existing printing or display technology have been able to realizePixel density even higher 1200PPI.
The first aspect of the invention is to provide a kind of digital information conversion method, and the digital information is non-image numberInformation, as shown in Figure 1, including the following steps：(1) the non-image digital information is converted into an at least width pixel map, whereinThe data that size is preset in the non-image digital information correspond to the color for being expressed as at least one of pixel map pixelValue；(2) pixel map is printed or is shown optically；The resolution ratio of printing or the display of the wherein described pixel mapMore than the resolution capability of human eye.
Non-image digital information described here includes but is not limited to：Text, text and image blend, application program, peacePacket, multi-medium data are filled, using data and other computers storage data, after the multi-medium data includes music, codingImage or video data etc..Particularly, in the present invention, the image after coding or video data are not considered as image digitizationContent is showed in the way of image them by the technology of the present invention because they are the transition forms of original imageWhen, not its original image presented, but the data after the coding of image conversion presentation.
In above-mentioned steps (1), non-image digital information is indicated first with color value, is then converted into a width pixel map.The pixel color value is the combination of the value or value of each color separated under RGB and CMYK patterns.By taking RGB patterns as an example, rgb colorPattern is a kind of color standard of industrial quarters, be by red (R), green (G), blue (B) three Color Channels variation and itMutual superposition obtain miscellaneous color, RGB is the color for representing three channels of red, green, blue.Assuming thatEach the color value in channel is indicated with 8 bits, theoretically, if the color recognition ability of camera is accurate enough, fromThe data of 24 bits can be identified in one pixel.And CMYK is also referred to as printing color pattern, represents four in printingKind color, C represent cyan (Cyan), and M represents carmetta (Magenta), and Y represents yellow (Yellow), and K represents black(Black).As RGB patterns, CMYK patterns also have channel, and are 4, each one of C, M, Y, K.Each channel colors of CMYKAnd dependent, the practical distinguishable number of colours that can be generated is ten thousand kinds of 100 × 100 × 100=100, theoretically, if cameraColor recognition ability it is accurate enough, then can identify the data of 19 bits from a CMYK pixel.With skillThe color recognition capability of the progress of art, the following camera can be further improved, the bit that a pixel can expressNumber can be more.In one embodiment of the invention, it according to the value range of non-image digital information, determines and needs how manyPixel indicates.By taking RGB patterns as an example, if value range can use the numberical range of 3 0-255 between, with 1 pixelIt indicates, because 1 pixel includes tri- kinds of colors of RGB, as shown in table 1 below, each pixel value has one-to-one mappingRelationship, the value range that 1 pixel determines is between 0-767 (256*3=768).Further, the institute in the step (1)The data for stating default size are the data of 24 bits, and value range is between 0-767.After the value for determining pixel, according to pixelPixel is included or being printed upon on the surface of certain material on electronic curtain by value.General non-image digital information quantity is more,Digital information can be so digitized to each value after coding, and (value is made of 3*8=24 bits, and value range isBetween 0-767), it is converted into the corresponding pixel with different colours value successively, and show successively.The mode presented successivelyCan be line by line, any scheduled shape such as square, circle.As described above, in order on the area of certain size, transfer ratioMore information content that human eye can be read use image as high as possible and resolution ratio are presented.For this purpose, minimum is in by weNow rate is set as the number of pixels (Pixel Per Inch) that per inch is possessed and is not less than 1200 (1200PPI) respectively.
As shown in Figure 1, one section of video information is passed through digital coding, all values of digital coding are converted into successivelyPixel with different colours value, and show successively, form rambling pixel map shown in FIG. 1.By pixelInformation restore, the pixel map will be reduced into before video data.
