Abstract

PURPOSE:To attain only one carrying of a section to be exposed and also to obtain an excellent color picture by emitting each red, green and blue color while switching them at each scanning line and giving a picture data of each color to a cathode ray picture while giving a shift to the colors by the scanning interval's share of each color. CONSTITUTION:The section 12 to be exposed is subjected to the cyclic exposure for one scanning line's share of a red picture data at first, the one scanning line's share of a green picture data and further one scanning line's share of a blue picture data repetitively. Thus, a position on the section 12 to be exposed subject to exposure based on the red picture data is overlapped with the exposure based on the green picture data at the ln-th cycle and also overlapped with the exposure based on the blue picture data at the 2ln-cycle. Then the exposure by the three color lights is finished on the said positin. The exposure like this is performed over the entire face of the section 12 to be exposed and a color picture is obtained by the development. Since there is almost no shear of the exposed position by the three color lights in this case, an excellent color picture is obtained.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a one-dimensional scanning cathode ray tube (including an optical fiber tube) equipped with a striped light emitting section capable of emitting light in each color of red, green, and blue. The present invention relates to an image recording apparatus having an exposure means.

(Prior Art) As one of the color image recording apparatuses using a one-dimensional scanning cathode ray tube, one having the configuration shown in FIG. 1 is known. This has red, green, and blue phosphors coated on the phosphor surfaces, respectively, and the cathode FJI tubes 1, 2. ζ3 is given image data of the color corresponding to and an inclined reflection mirror 6) so as to be incident on a C lume (exposed area) 7. The reference numeral 8 in the figure is a stage that is moved left and right by a step motor (not shown).
The mirror 6 and film 7 are placed on the stage 8 and moved to perform sub-scanning. However, this recording apparatus requires three cathode ray tubes 1 to 3, which has the drawback of increasing the scale of the apparatus.

In addition, as another conventional device, the surface to be scanned by the electron beam is red,
One type of LC is known, which uses a single cathode ray method in which phosphors of three colors, green and blue, are applied in stripes. In this recording device, in order to perform exposure for each color separately, the exposed area is repeatedly transported three times, and at each transport time, exposure is performed based on both data for the corresponding color, thereby obtaining a color image. . In this recording device, the drawbacks of the conventional device described above have been eliminated, but the exposed area is returned to its initial position and the images of each color overlap.
The equipment required to do so is complicated, and the equipment is becoming larger. Moreover, despite this increase in size, the exposure position due to the three-color light is significantly shifted, and a good f-if-color image cannot be obtained.

(Object of the invention) The present invention was made in view of these 41 problems, and
The purpose was to create an image recording device that uses a single cathode ray tube, transports the exposed area only once, and can produce good color images. - It is about providing.

(Structure of the invention) 4111 or red, green of the present invention which constitutes this purpose.

In an image recording apparatus whose exposure means is a one-dimensional scanning cathode ray tube equipped with a striped light emitting section, the light emission of each color of blue can be switched at a predetermined scan interval. 3. (Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a block diagram showing one embodiment of the present invention.

In the figure, numeral 11 is a one-dimensional scanning cathode ray tube, and here a Δ physical fiber tube is shown. The fluorescent surface portion of the cathode ray tube 11 is a red fluorescent material 11a, as shown in FIG.

It is painted striped with green phosphor 11b and old phosphor 11c. When each of the phosphors 11a, 11b, and 11c forming this striped light emitting part is scanned by the ffl beam, it produces red light, green light, and blue light, respectively, and this light has an optical axis in the horizontal direction in the figure.

It is preferable that the The expansion 11 (transfer photosensitive material) referred to here is, for example, one constructed as a film of Instances 1 to N (the film is photosensitive), and uses a reversal emulsion in the 6 layers, and a dye and a fastener under each photosensitive layer. A layer containing a dyO-releser bonded with a diffusible group is provided, and the silver halide in the exposed area is not transferred because it is a reversal emulsion, but the silver halide in the unexposed area (dyO-releser) is On the same day when it is reduced with momme medicine, the development main festival is 01st Risane,
Due to the action of this oxidation product and alkali, the diary release
The dye is released from the film, and the diffusible dye spreads to the image-receiving layer (transferred) and combines with the Kir-1 compound in the image-receiving layer to form a positive dye image. The time processing is efficient, and the 1R1 photos have excellent resolution, color reproducibility, etc., and are of the same quality as general silver halide film.

<m+n> scanning lines (the three scanning lines are located at the center of the phosphors 11a, 11b, 11c, respectively). Although different from this embodiment, the order of light emission can be set as appropriate.

Returning to Figure 2 again, 14. ．． Reference numerals 15 and 16 denote frame memories, and the frame memories 14 and 15 and 16 store image data for exposure with red light, green light, and blue light, respectively, and the data in each frame memory 14 to 16 is The input signal is selected by a multiplexer 17 and input to the cathode ray tube 11 via a 1/A converter 18.

In this embodiment, the direction of conveyance of the exposed portion 12 is the downward direction (direction of the arrow) in FIG. /++ (mm). However, this value is obtained when 113'E is set to n dots/ml in the solution 41 of the system. Further, the frame memory 14. ．． When the frame memory 14 outputs data corresponding to the first scanning line as red scanning line data, the data being read from 15° 16 is assumed to be green scanning line data and T, 1. - Outputs the data of the lnth [:1] and outputs the data of the 1st to 21111sth frames (16 is the scanning line data of b). For example, 1

If so, the green data will be output 30 scan lines closer than the red data, and the blue data will be output 30 scan lines closer than the green data.
0; J': The output starts to be output after a delay of the foot line 3
The reason for this is to apply 6 tomoe data falling at the same position 12I of the original image to the same position of the exposed area.

- According to the above description, while the exposed part 12 is being conveyed downward in FIG. Recycle exposure is repeated for one scanning line and then one scanning line of the blue image data.

Then, the exposure to the three-color light at that position is completed.

Such exposure is performed in four areas on the entire surface of the exposed area 12, and a color image is obtained by development.

In this case, there is almost no deviation in the exposure position due to the three-color light, so a good color image can be obtained.
