Incorporated by reference to referring to Figures 1 and 2, the photo-printer 100 that the utility model embodiment is provided includes printer sheet Body 110 and paper storehouses 120, printer body 110 and paper storehouses 120 are detachably connected.Printer body 110 include shell 130 and The mainboard being set in shell 130, paper storehouses 120 and shell 130 constitute enclosure space, and heat-sensitive paper is placed in paper storehouses 120.

In the present embodiment, key-press module 111, photographic device 113, viewfinder 114 and instruction mould are provided on shell 130 Block 116 is provided with main control chip 112, thermal printing head 115 and power module 117 on mainboard.Main control chip 112 and button mould Block 111, photographic device 113, viewfinder 114, indicating module 116, thermal printing head 115, power module 117 are electrically connected.

In the present embodiment, key-press module 111 is electrically connected with main control chip 112, and is electrically connected with power module 117, is pressed Key module 111 generates photographing instruction for the photographing operation based on user, for example, preparing to clap when user pushes button module 111 According to when, key-press module 111 generate triggering command, triggering photographic device 113 start to work.As an implementation, button mould Block 111 may be, but not limited to, button switch.

In the present embodiment, main control chip 112 is for control button module 111, photographic device 113,116 and of indicating module Thermal printing head 115 starts or stops work, for example, when user pushes button module 111, the control instruction of main control chip 112 Module 116 is indicated.

As an implementation, main control chip 112 can be a kind of IC chip, have signal handling capacity, Main control chip 112 can be at general processor, including central processing unit (CentralProcessing Unit, CPU), network Manage device (Network Processor, NP), speech processor and video processor etc., can also be digital signal processor, Application-specific integrated circuit, field programmable gate array either other programmable logic device, discrete gate or transistor logic, Discrete hardware components.As an implementation, main control chip 112 may be, but not limited to, microcontroller.

In the present embodiment, photographic device 113 is electrically connected with main control chip 112, and is electrically connected with power module 117, is taken the photograph Image information as device 113 for acquiring outside under the triggering of photographing instruction, and image information is sent to main control chip 112.As an implementation, photographic device 113 may be, but not limited to, digital camera.

In the present embodiment, viewfinder 114 is electrically connected with photographic device 113, and viewfinder 114 is for showing photographic device 113 viewfinder range, user can check the viewfinder range of photographic device 113 by viewfinder 114.As a kind of embodiment party Formula, viewfinder 114 may be, but not limited to, black and white view finder, colored view finder etc..

In the present embodiment, photographic device 113 acquires external image information, and the image information is sent to master control core After piece 112, which is converted to black white image by main control chip 112, and controls thermal printing head 115 by the artwork master As printing on heat-sensitive paper.

As an implementation, after main control chip 112 gets image information, by image information be compressed into width with The compressed picture that the maximum width of thermal printing head 115 is consistent and the ratio of width to height is consistent with original image information；Then compression figure is obtained The rgb pixel array of piece, the form of the rgb pixel array are as follows：

Int [] ArrRGB=px0, px1, px2, px3, px4, px5,, }；

The rgb pixel array is to be stored the pixel of compressed picture successively from left to right, from top to bottom, One element of rgb pixel array represents a pixel of compressed picture, each element by each pixel RGB tri- Component value forms and is 24 bits, and each component value is indicated by 8 bits in wherein RGB.

It is compressed picture by original image Information Compression, and after getting the rgb pixel array of compressed picture, needing will be color The compressed picture of color is converted to gray-scale map.Formula can be utilized according to tri- component values of RGB of each pixel in compressed picture Gray=R*0.3+G*0.59+B*0.11 calculates the gray value of each pixel.

It calculates in compressed picture after the gray value of each pixel, each element in rgb pixel array is used into ash Angle value is replaced, and gray-scale pixels array ArrGray is obtained, for example, ArrGray=[200, Isosorbide-5-Nitrae, 255 ... ..., 0 ,], then pass through this Gray-scale pixels array ArrGray generates gray-scale map.

Next it needs to carry out binaryzation to gray-scale map to obtain black white image, when binaryzation needs with 128 to be threshold values, such as The pixel value of some pixel of fruit is more than 128, then it is 255 that the pixel value, which is arranged, on the contrary then be set as 0.Due to every in gray-scale map The pixel value range of a pixel is 0~255, and therefore, the more pixel close with threshold values, the quantization generated after binaryzation misses Difference is bigger.

To eliminate the quantization error generated after binaryzation, first have to carry out at error diffusion gray-scale map before binaryzation Reason, that is to say, that increase to the residual quantization error of any one pixel on its adjacent pixel so that the figure of final process It as visually tending to mitigate, can be realized with formula, wherein * indicates that the pixel being presently processing, white space indicate The pixel of completion is handled, from left all right, quantizing pixel value one by one from top to bottom in processing procedure.The amount of each pixel Change error and be added to the other pixels adjacent with the pixel, while not changing the pixel for having handled completion.

Error DIFFUSION TREATMENT is carried out to gray-scale map and then two are carried out to the element inside gray-scale pixels array ArrGray Value is handled, and can obtain black white image.

In the present embodiment, thermal printing head 115 is electrically connected with main control chip 112, and is electrically connected with power module 117. Thermal printing head 115 is used under the control of main control chip 112, and black white image is printed on heat-sensitive paper.Thermal printing head 115 It being made of row's heating element, these heating elements resistance having the same will produce high temperature when by a constant current, to Heat-sensitive paper is set to reveal color.
