Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pixel image forming apparatus for use in three-dimensional printed matter and variable printed matter using a lenticular screen.

Regarding three-dimensional printed matter, variable printed matter, and its manufacturing method using a lenticular screen (continuous semi-cylindrical screen), see, for example, Japanese Patent No. 88069 and Japanese Patent No. 6.
As shown in Japanese Patent Publication No. 6635, Japanese Patent Publication No. 49-11940, etc., a pixel image is arranged on the back side of a lenticular screen, and the pixel image is formed by forming a plurality of images into stripes. A plurality of images formed into stripes at each lens pitch are arranged in the same order.

There are many methods for forming this pixel image, but all conventional methods involve forming multiple images in an array as described above using a photographic method, and are complicated and involve an extremely large number of steps. It was hot.

The present invention uses an electrical method to obtain pixel images necessary for three-dimensional prints and variable prints from a plurality of images, thereby forming pixel images much more easily and inexpensively than conventional methods. The present invention will be explained in detail with reference to one example below.

As shown in FIG. 1, the subject 1 is photographed at an appropriate solid angle using television cameras 2 and 7 to obtain left and right image signals, and after checking the photographed images on television monitors 3 and 3', frame memories 4 and 1 are respectively taken. recorded as a still image. Next, among the left and right image signals read out from the frame memories 4 and 4', horizontal synchronization signals are transferred to synchronization separation circuits 6 and 6'.
is separated and input to the control circuit 11.

The control circuit 11 uses this horizontal synchronization signal and inputs the clock pulse from the clock pulse generation circuit 12 to the control circuit 11 for only one scanning line of the image signals read out from the frame memories 4, 4'. Using the generated clock pulses, the A/D converter 5 converts them into digital image signals, and similarly inputs the clock pulses from the clock pulse generation circuit 12 to the control circuit 11, and uses the generated clock pulses to perform shifting. Write to registers 7 and 7'.

Scanning image signals are not written until the digital image signals written in the shift registers 7, 7' are read out. Among the digital image signals written in the shift register 7, γ, a command signal coming from the engraving machine 10 is input to the control circuit 11, and a read signal generated is used to read out the digital image for one scan that is input to the shift register 7. The signal is read out, converted back to an analog image signal by a D/A converter 8, amplified by an amplifier 9, and sent to an engraving machine 10, where one scanning image is engraved onto a printing plate. This engraving machine 10 is, for example, an engraving machine as shown in the specifications of U, S, P2, 986, 598, etc., in which a needle provided in an engraving head moves up and down in accordance with an image signal, and at the same time a plate as an object to be engraved is moved up and down. The plate material is engraved according to the image signal by reciprocating the material. When engraving for one scanning line is completed, a command signal is sent from the engraving machine 10 to the control circuit 11, and the control circuit 11 then outputs a read signal to the shift register 7', and this signal is input to the shift register 7'. The digital image signal for one scan is read out, and the D/
It is returned to an analog image signal by the A converter V, amplified by the amplifier 9, and sent to the engraving machine 10.
Engrave the scanned image and place it on one of the lenticular screens.
A pixel image corresponding to the pitch is formed.

While the digital image signal from the shift register 7' is being written out, the image signal for the second scan of the still image signal input to the frame memory 4 is transferred to the shift register 7 from the A/D converter 5. input through.

When the image signal for one scan input to the shift register 7/ is read out and the engraving is completed, the image signal for the second scan, that is, the next pitch, input to the shift register 7 is then engraved. In this way, the image signals of the scanning lines of the left and right parallax images of the subject 1 recorded in the frame memories 4 and 1 are read out alternately, and the engraving machine 10 engraves them onto a plate material.

The images thus recorded in the frame memories 4, 4' are engraved onto a plate material to obtain a plate material with a three-dimensional pixel image engraved thereon.

Incidentally, by passing the image signal through the phase inversion switching circuit 13, both the positive and negative images of the subject 1 can be engraved.

In the present invention, an embodiment using an engraving machine as an output mechanism has been shown, but the invention is not necessarily limited to an engraving machine. For example, a pixel image can be formed by scanning a photosensitive film with a photoelectric head such as a color scanner. It may also be output as a film.

Also, although the left and right parallax images (2 images) were used as pixel images, 3
It is clear that it can also be an image or more images. Also, in the above embodiment, one scanning line was recorded in a half-pitch of the lenticular screen, but if the number of scanning lines is not one but multiple, for example three, First, the first scanning line signal among the image signals recorded in the frame memory 4 is input to the shift register 7, and is read out and engraved.

And while engraving this signal, shift register 7
Write the second scanning line of the image signal recorded in the frame memory 4 to ', and when the signal input to the shift register 7 is finished engraving, read the signal input to the shift register 7' and start engraving. do. During this time, the third scanning line of the image signal recorded in the frame memory 4 is written into the shift register 7. The first of the image signals recorded in the frame memory 4 in this way
~ The third scanning line segment is engraved, while the first scanning line of the image signal recorded in the frame memory 4' is recorded in the frame memory 4 input to the shift register 7. The signal for the third scanning line of the image signal is read out and written to the shift register 7' while it is being engraved, and after the signal input to the shift register 7 is completely engraved, the frame is memory 4
The engraving is performed next to the line engraved by the third scanning line in the image signal recorded in . By repeating this process, each scanning line of the image signal in the frame memory 4 can be taken out alternately every third and engraved. Since the present invention has the above configuration, three-dimensional,
Pixel images required for variable printed matter can be formed extremely easily without using photographic methods.

In addition, traditional photographic methods require many steps,
In addition, the present invention requires a skilled photographer, but the present invention is easy to operate and can form pixel images in an extremely short time.However, the conventional method requires a large amount of film and is difficult to shoot in one shot. However, according to the present invention, consumption of film and the like is reduced, and one-shot photography is easy.
