Pattern is a kind of color standard of industrial quarters, be by red (R), green (G), blue (B) three Color Channels variation and it
Mutual superposition obtain miscellaneous color, RGB is the color for representing three channels of red, green, blue.Assuming that
Each the color value in channel is indicated with 8 bits, theoretically, if the color recognition ability of camera is accurate enough, from
The data of 24 bits can be identified in one pixel.And CMYK is also referred to as printing color pattern, represents four in printing
Kind 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 CMYK
And dependent, the practical distinguishable number of colours that can be generated is ten thousand kinds of 100 × 100 × 100=100, theoretically, if camera
Color recognition ability it is accurate enough, then can identify the data of 19 bits from a CMYK pixel.With skill
The color recognition capability of the progress of art, the following camera can be further improved, the bit that a pixel can express
Number can be more.In one embodiment of the invention, it according to the value range of non-image digital information, determines and needs how many
Pixel indicates.By taking RGB patterns as an example, if value range can use the numberical range of 3 0-255 between, with 1 pixel
It indicates, because 1 pixel includes tri- kinds of colors of RGB, as shown in table 1 below, each pixel value has one-to-one mapping
Relationship, 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 pixel
Pixel 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 is
Between 0-767), it is converted into the corresponding pixel with different colours value successively, and show successively.The mode presented successively
Can be line by line, any scheduled shape such as square, circle.As described above, in order on the area of certain size, transfer ratio
More 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 we
Now 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 successively
Pixel with different colours value, and show successively, form rambling pixel map shown in FIG. 1.By pixel
Information restore, the pixel map will be reduced into before video data.
