원고화상으로부터 얻어지는 화상정보신호를 제조정기구에서 처리하고, 그 처리신호에 의거하여, 기록용지상에 1색 또는 다색의 중간조를 갖는 기록화상을 형성하는 더어멀프린터에 있어서, 전기제조조정기구가, 화상정보신호에 의거하는 원고화상상에서의 임의의 표본점의 기초농도치(x) (그 표본점에 있어서의 농도치와 동화상상의 최명부에 있어서의 농도치와의 차)를 형성되어지는 기록화상의 전기표본점에 대응하는 위치에 있어서의 화소농도치(y)에 하기의 관계식(1)에 의해 변환처리하는 것을 특징으로 하는 더어멀프린터.In a thermal printer in which an image information signal obtained from an original image is processed by a manufacturing mechanism, and a recording image having one color or a multicolor halftone is formed on a recording paper based on the processing signal. A recording image on which an elementary density value x of an arbitrary sample point in the original image based on the image information signal (the difference between the density value at the sample point and the density value at the edge of the moving image) is formed. A thermal printer according to the following equation (1) for converting the pixel concentration value y at a position corresponding to the electric sample point. 관계식Relation 단, x:원고화상상의 임의의 표본점 X의 기초농도치, 즉, 동화상의 임의의 표본점 X에 있어서의 농도치로부터, 동화상의 최명부 H에 있어서의 농도치를 차감한 농도치, y:형성되어지는 기록화상상에 있어서의 전기 X에 대응하는 위치 Y의 화소농도치, yH:형성되어지는 기록화상의 최명부 H의 화소에 대하여 설정되는, 소망의 크기의 화소농도치, ys:형성되어지는 기록화상의 최암부 S의 화소에 대하여 설정되는 소망의 크기의 화소농도치, α:기록용지의 방사율, y:β=10-r에 의해서 구하여지는 수치, K:r/(원고화상의 농도역)에 의해서 구하여지는 수치, r:임의의 계수를 각각 나타냄.However, x: the basic concentration value of any sample point X of the original image, that is, the concentration value obtained by subtracting the concentration value at the outermost part H of the moving image from the concentration value at any sample point X of the moving image, and y: recording. Pixel concentration value at position Y corresponding to electricity X in the imagination, y H : Pixel concentration value of desired size, which is set for the pixel of the brightest portion H of the recording image to be formed, y s : Maximum of the recording image to be formed The pixel concentration value of the desired size set for the pixel of the dark portion S, α: emissivity of the recording paper, a value obtained by y: β = 10 -r , and K: r / (concentration range of the original image). Numerical value, r: represents an arbitrary coefficient, respectively. 중간조를 갖는 기록화상이, 디터매트릭스(Dither Matrix)에 의해 형성된 도트밀도의 변조화상인 특허청구 제1항에 기재한 더어멀프린터.The thermal printer according to claim 1, wherein the recording image having an intermediate tone is a modulated image of dot density formed by Dither Matrix. 중간조를 갖는 기록화상이, 기록도트지름을 변화시키므로써 형성되어진 도트사이즈의 변조화상인 특허청구 제1항에 기재한 더어멀프린터.The thermal printer according to claim 1, wherein the recording image having an intermediate tone is a dot-size modulation image formed by changing the recording dot diameter. 중간조를 갖는 기록화상이, 기록도트 자체의 농도를 변화시키므로서 형성된 것인 특허청구 제1항에 기재한 더어멀프린터.The thermal printer according to claim 1, wherein the recording image having a halftone is formed by changing the concentration of the recording dot itself. 다색의 기록화상이, 복수의 인자헤드와, 그것에 대용하는 특수잉크필름에 의해 얻어지는 특허청구 제1∼제4항의 어느 것인가 하나에 기재한 더어멀프린터.The thermal printer according to any one of claims 1 to 4, wherein the multicolor recording image is obtained by a plurality of printing heads and a special ink film substituted therewith. 다색의 기록화상이, 단일의 인자헤드와 다색이 반복되게 배열된 잉크필름과에 의해서 얻어지는 특허청구 제1∼제4항의 어느 것인가 하나에 기재한 더어멀프린터.The thermal printer according to any one of claims 1 to 4, wherein the multicolor recording image is obtained by a single printing head and an ink film arranged in such a manner that the multicolor is repeated. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
