Abstract

PROBLEM TO BE SOLVED: To eliminate a noise in a pitch direction caused in the case of printing by a digital printer, by adjusting the paper feeding amount and performing printing so that respective dots have overlapping within the range of a specified value. SOLUTION: In this method; a printer conventionally used can be used as the digital printer, and the respective dots for printing are printed so that they may overlap each other by 0 to 45% by adjusting the paper feeding amount. The driving force of a pulse motor 1 is transmitted to a platen roller 2. Since the feeding amount of recording paper 3 is decided according to the rotational amount of the roller 2, it can be varied so that the respective dots may be somewhat superposed in a paper feeding direction by producing the printer considering the diameter of the roller 2 and a gear ratio between the motor 1 and the roller 2. An ink ribbon 5 is fed by one dot every time a thermal head 4 prints one dot. The printer by which the respective dots are somewhat superposed in the paper feeding direction by such operation is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a stereoscopic image which is the basis of a stereoscopic image by a digital printer when obtaining a stereoscopic image which can be stereoscopically viewed through a lenticular sheet.

[0002]

2. Description of the Related Art Heretofore, a stereoscopic image which can be stereoscopically viewed using a lenticular sheet has been created as follows.

First, a plurality of original image films for forming a three-dimensional image on which an original image for forming a three-dimensional image having parallax is formed are prepared by using a multi-view camera or computer graphic processing.

[0004] Next, each of the original image films is aligned such that the positions of the original images are aligned with respect to a feature point (for example, a portion which does not appear to be raised or appears to be receding) in the original image. After the registration, the original image film is provided with a register hole, and the feature points of each original image film are arranged at the same position by the register hole. This is because each original image film is often formed at a position where the original image is slightly shifted.

The original image film is attached to a synthesizing machine through a register hole, and the original image (characteristic points) of the original image film is arranged at a fixed position, and the original image pattern of the original image film is enlarged at a predetermined magnification. Then, the film for synthetic image is exposed through a lenticular plate. For each exposure, the lenticular sheet and the synthetic image film are moved by one pitch of the lenticular film / the number of original images so that the divided compressed images of each original image are arranged in a predetermined arrangement on the stereoscopically-viewable image film. become.

By superimposing the observation lenticular sheet under the same conditions as the lenticular sheet from the stereoscopically-obtained image thus obtained, a stereoscopic image can be observed through the observation lenticular sheet. In addition, a lenticular sheet and a film for synthesis are treated as an integrated product, and a processing process is performed on the lenticular sheet and the synthetic film to obtain a sheet that can be stereoscopically viewed.

However, such positioning of the original image film is troublesome because fine adjustment is manually performed using a loupe. In particular, in order to create an actual stereoscopic photograph or stereoscopic display, a large number of original image films having parallax are required, so that the above-described alignment work has been very complicated. In addition, since the accuracy of the alignment is poor, the vertical parallax remains, and the stereoscopic vision becomes difficult, or the stereoscopically viewed part protrudes too far in front or sinks too far behind, so that it is difficult to obtain a good stereoscopic image. was there.

Therefore, it has been considered to output a lenticular image using a digital printer. In this case, since the digital printer has a small gap between each dot of a printed matter, this is called a three-dimensional image for a lenticular sheet. When used as a collation image, this gap is enlarged by the lens of the lenticular sheet, so that the contrast of the stereoscopic image obtained using the lenticular sheet can be reduced, or noise that is thin in the pitch direction of the lenticular sheet can be reduced. There was a phenomenon that appeared.

[0009]

SUMMARY OF THE INVENTION The present invention has been made to solve this problem, and it is an object of the present invention to provide a method for printing a lenticular sheet stereoscopic image forming original image by a digital printer. It is an object of the present invention to provide a method of creating a stereoscopically-viewed image in which noise in the pitch direction is eliminated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail. As a method of creating an original image for forming a stereoscopically matched image according to the pitch of the lenticular lens according to the present invention, the original image can be created by using a conventional multi-view camera or by computer graphic processing.

As the digital printer used in the present invention, a conventionally used digital printer can be used. By adjusting the paper feed amount, each dot of printing can be 0-45%.
Can be printed so as to have an overlap.

As a method of reducing the paper feed amount of the digital printer according to the present invention, the configuration of the digital printer device can be made or adjusted so that the dots of the printed matter slightly overlap in the paper feed direction. .

Hereinafter, the configuration of the digital printer according to the present invention will be described in detail with reference to FIG. The driving force of the pulse motor (1) is sent to the platen roller (2), and the amount of rotation of the recording paper (3) is determined by the amount of rotation of (2), so that the diameter of (2) and (1) and (2) If it is manufactured in consideration of the gear ratio, the feed amount of (3) can be changed so that the dots slightly overlap in the paper feed direction.

The ink ribbon of (5) is fed by one dot each time the thermal head (4) prints one dot. By such an operation, a printing apparatus in which each dot slightly overlaps in the paper feeding direction is obtained.

These techniques can be applied to thermal printers, sublimation transfer printers, laser type film printers, laser beam printers, laser type photographic paper printers, ink jet printer imagesetters, direct offset plate making devices and the like.

A three-dimensional image can be observed by sticking the paper output direction of the printed matter output in this way and the pitch direction of the lenticular sheet together.

[0018]

As described above, according to the present invention, a stereoscopic image is formed so that each dot slightly overlaps without a gap, so that a lenticular image can be output by a conventional digital printer. The noise of the thin streaks in the pitch direction of the lenticular sheet at the time of stereoscopic image observation, which is generated by enlarging the generated gap between the dots by the lens of the lenticular sheet, can be eliminated. This has made it possible to more easily obtain high-quality stereoscopic images with a digital printer.
