发明名称 OPTICAL PRINTING DEVICE
摘要 <p>PURPOSE:To obtain a clear image by forming a device of an image body which is constituted of a self light emitting or shutter type picture element whose numerical aperture is <=100%, an image receiving body which is photosensitive and an interlocking means for allowing the image body and the image receiving body to interlock relatively and setting the numerical aperture at about 100%. CONSTITUTION:This device is constituted of the image body 3 which is constituted of the self light emitting or shutter type picture element whose numerical aperture is <=100%, the photosensitive image receiving body 6, and the interlocking means 7 for allowing the image body 3 and the image receiving body 6 to interlock relatively, and the numerical aperture is set at about 100%. In the case that the numerical aperture of the picture element cell of a shutter 3 is >=25%, an overlapped part is caused and overexposure occurs. In the case that the numerical aperture is <=25%, a thin lattice is newly caused. Therefore, a part where the lattice is caused is allowed to compensate for data corresponding to correct image data so as to obtain the clear image with colorfulness. Thus, the natural clear printed image is obtained.</p>
