The accompanying drawing explanation
Fig. 1 is the flow chart of the Method of printing of medical black and white color mix image in the embodiment of the present invention;
The realization of the object of the invention, functional characteristics and advantage, in connection with embodiment, are described further with reference to accompanying drawing.
The specific embodiment
Describe technical scheme of the present invention in detail below with reference to drawings and the specific embodiments, so as clearer, understand invention essence of the present invention intuitively.
Shown in Fig. 1, the Method of printing of the medical black and white color mix image of the present embodiment comprises the following steps:
S1: the inkjet channel of setting ink-jet printer is some black ink passages and some color inks passages, the black ink passage black ink of packing into, the color inks passage color ink of packing into;
S2: by DICOM print protocol or printer communication agreement, receive print image data;
S3: the described print image data received is carried out to the lattice processing, form a plurality of image subblocks, each described image subblock comprises at least one pair independently or complete image;
S4: each described image subblock is carried out to the colored judgement of black and white; Described image subblock is divided into to black white image sub-block and coloured image sub-block.
S5: adopt the black and white algorithm of color separation to carry out color separation processing to the black white image sub-block, to the coloured image sub-block, adopt the color separation algorithm to carry out color separation processing;
S6: export the view data after color separation processing to printer or printhead by communication protocol.
It should be noted that: described printer communication agreement is the communication protocol that printer carries.
In described step S1, described black ink passage at least comprises two groups, and described color inks passage at least comprises three groups.So that in the color separation processing process of step S5, add at least two group black ink after adopting the black and white algorithm of color separation to calculate to the black white image sub-block and carry out color separation processing, add at least three group color ink after adopting the color separation algorithm to calculate to the coloured image sub-block and carry out color separation processing, this color separation processing mode had both guaranteed high optical density (OD) and the high-contrast of black white image, guarantee again the gorgeous degree of coloured image, met the high standard of medical image fully.
Described print image data in described step S2 comprises: by any one or several in a plurality of independently image subblock data of DICOM print protocol transmission, the view data integrated of transmitting by the DICOM print protocol and the view data integrated by the printer communication protocol transmission.
The form of above-mentioned print image data comprises but is not defined as DICOM form, BMP form, jpeg format, tiff format, PCX form, PSD form and CDR form.
Thereby, the first situation: when described print image data is a plurality of independently image subblock data of transmitting by the DICOM print protocol, described step S3 is specially: follow the DICOM print protocol described a plurality of independently image subblocks are positioned to processing, so that image subblock is pressed the pre-defined rule location; Described step S4 is specially: directly read the image category in the file header of described image subblock, common described image category comprises black white image and coloured image.
The second situation: when described print image data is the view data integrated of transmitting by the DICOM print protocol, in this view data integrated, usually include many secondary independently or complete image, so now, described step S3 is specially: to described integrated image carry out the lattice processing according to image information, form a plurality of described image subblocks; Described step S4 is specially: detect the image category of each described image subblock of judgement, common described image category comprises black white image and coloured image.
The third situation: when described print image data for by the printer communication protocol transmission integrated be integrated image the time, in this view data integrated, usually include many secondary independently or complete image, so now, described step S3 is specially: the described image be integrated of having integrated is carried out to the lattice processing, form a plurality of described image subblocks; Described step S4 is specially: detect the image category of the described image subblock of judgement, common described image category comprises black white image and coloured image.
Wherein, in the described step S4 of above-mentioned the second situation and the third situation, described detection judges that the mode of the image category of each described image subblock is generally: the image category according to the value judgement image subblock of the color channel of image subblock pixel judges that this image subblock is black white image if in image subblock, the value of all color channels of each pixel is all identical; If have the value of all color channels of a pixel entirely not identical in image subblock, judge that this image subblock is coloured image.
Enter step S5 after completing steps S1, S2, S3 and S4: printer adds at least two group black ink after can adopting the black and white algorithm of color separation to calculate to above-mentioned black white image sub-block and carries out color separation processing, add at least three group color ink after adopting the color separation algorithm to calculate to the coloured image sub-block and carry out color separation processing, and its processing mode can be to process line by line, can be also that pointwise is processed.For the method for color separation processing, because be known prior art, at this, specifically do not describe in detail, for example, can be with reference to the technical scheme of the patent No. 200810227256.0, patent name " a kind of color separation processing method and device of image file ".
Finally carry out step S6: export the view data after color separation processing to printer or printhead by communication protocol.Specifically, can export by the communication protocol of printer printer to and print, also can export printhead prints to by the communication protocol of printhead.
Above six steps can complete the Method of printing of the medical black and white color mix image of the present embodiment.
In sum, the Method of printing of medical black and white color mix image of the present invention first receives by DICOM print protocol or printer communication agreement the print image data that comprises the three types described in embodiment, again each image subblock of described print image data carried out to the colored judgement of black and white, to the black white image sub-block, adopt the black and white algorithm of color separation to carry out color separation processing, after adopting the color separation algorithm to carry out color separation processing to the coloured image sub-block, can print out the image that the black and white colour mixes mutually.And in the color separation processing process, add at least two group black ink after adopting the black and white algorithm of color separation to calculate to the black white image sub-block and carry out color separation processing, add at least three group color ink after adopting the color separation algorithm to calculate to the coloured image sub-block and carry out color separation processing, this color separation processing mode had both guaranteed high optical density (OD) and the high-contrast of black white image, guarantee again the gorgeous degree of coloured image, met the high standard of medical image fully.This Method of printing of the present invention not only process is simple, easy to operate, is beneficial to the doctor and reads sheet, has avoided again the waste of the black and white colour cost that printing film causes respectively.
The foregoing is only the preferred embodiments of the present invention; not thereby limit its scope of the claims; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
