日翻英：
Mr. Asakura: In this series, but has been covered so far about the display and 4K projectors, over in March from February, has been a pilgrimage across the country in the event of Sony and JVC. Future will continue until May. In the event, we have been preached in detail the difference between full HD projector impressed, and Effectiveness of a home theater, you may notice in the event that I am in reverse. This time I measure with strength and character of the projector of both companies, as an interim report, I would like to report that we have learned from the tour.
Recently, in conjunction with Sony's "PlayStation 3" and VPL-VW1000ES, today announced a software Utsushidaseru native image content stored within the PS3. Toshiba has developed the "4K box" that can be projected to 4K2K, "55X3" 4 HDMI cables also use the box. You can see the video taken with a JVC video camera and 4K content that was created with the PC. I have become active movement to come here this way, reflecting the native 4K content.
Mr. Asakura: 4K if the software package for home use if You do not know how to fix, I can demonstrate its ability to fully 4K projectors, however, is currently the main source of Blu-ray Disc. Even in the event, and then listen to up-converted to 4K and 2K content mainly.
However, up-conversion of content from 2K to contain a subtle issue, in the traditional Apukon mean to expand to four times, accompanied by a blur really. In mere Apukon video and you will have less blurring of the same level of image quality, at worst. As long as there is no technology or something random, it would blur because there will of course make it one of the pixels of four pixels. However, use a 4K projector, you can experience a strange sense of resolution that goes up rather.
In the event of a provincial city, the user Rashiki veteran, "Because I only have 2K content, this projector does not make sense," meaning the term had been whispered that you were on target. But I was hot story begins emergency viewers, surprised out a result that exceeds the forecast, and was touched by the image of 4K. For up-converted to 4K to 2K, as this user, there is also skeptical of course. Indeed, some are not very effective BD software, that some very large effect was confirmed again in reverse.
So, manufacturers are making these 4K projectors, what did you do. According to JVC, they think of "Benefits of 4K" is, or what the picture is taken at 4K First of all, or it may be edited, that remain even if the signal is fine in 2K. Victor is called as "traces of 4K" this. 2K does not remain completely invisible, and to up-convert the signal of the 4K you'll see fine. This is the policy design of JVC.
In the event, comparing the image was projected investment of BD Togetsukyo Bridge Arashiyama, Kyoto, taken with a JVC 4K camera first, groans of "Oh ~Tsu" is the venue of Sapporo has occurred. This video is light and sparkling water, mountains in the back of the forest can be seen. Roundness of the mountain as I feel in the 2K, to recognize the individual trees are not enough. Was Apukon to 4K, the feeling becomes the gorgeous glitter of the surface of the water first, went up to the overwhelming clarity of the water but also
In addition it different trees of the forest people. There are (stereoscopic) bulge into trees one by one, until you can feel the difference of each color. 2K projectors are available for comparison, the evaluation of a high quality surface is "DLA-HD100" and earlier "DLA-X30", there was a difference in the uniform. When up-converted to 4K, as well as sense of resolution, change is coming to represent color and contrast. This means that the original 4K footage ability had, that come back to some extent. I was able to feel the "traces of 4K" clearly.
improvement of a mere resolution. 4K is coming overwhelmingly conveyed the message to loquacity.
- What is that new film production that enable 4K
Mr. Asakura: Scene, 4K is also active in addition to. In addition to the digital cinema of the original 4K, will restore an important content of BD masterpiece of the past. What "The Sound of Music" for example is scanned at 8K, make repair and mastering is 4K, BD turned into down-converted to the final 2K. Originally because there was a resolution of 8K, "traces of an 8K" Why is there. There is "evidence of editing of 4K" in the editing, I will also double structure of traces of hi-res.
Sony has been playing and JVC, the "Sound of Music" in both events. Doremi scene of the song of chapter 19. Now here is a lot of messages were put.
Prior to that chapter 18 begins with a scene that looked at teacher Maria curtains of the house. Children do not have clothes to go to play. Because we believe that teacher Maria just replace the curtains, and Let 'dress to it. In the second half of chapter 18, I have been strutting the streets of Salzburg, the children are wearing clothes made here in the curtain.
For the design of clothes that are large, curtain fabric you are using a 2K projector, but also to understand, until the texture is good but I do not know. At 4K, fine texture and find that clothes made but you will see exactly curtain. That has been talked about in that scene, it is clearly understood.
I was impressed by one of the other is a tomato fruit was displayed at the storefront of the shop. Rounded and polished, was clearly out. Same as with the picture of Arashiyama, there is a completely different world in 4K texture for three-dimensional representation and 2K.
Once in Chapter 19, children and teacher Maria sit on the lawn, steep mountains to the left of it, in the back will be the scene that spread the sky. Here is a look at the reproducibility of the lawn. The flat lawn is visible to 2K, you know the difference between a color and texture in 4K. I can see that the curtain fabric is also clearly the children's clothes, real trees and mountain ridges and look in the distance. If you look ahead for a moment, distant view is looking blue tinge.
This is what is called aerial perspective. It looks blue sky is in the process of light coming through the atmosphere, leaving only blue because of the various wavelengths of light. In the same way, the foreground is the distant mountains are blue color makes it look even become colorful. If 2K, but the impression would be that quiet blue, like artificial mountains and grass also, the individual objects is also come out in the real sense of depth and really look at 4K.
Recent restoration work and Hepburn work, such as "Ben-Hur", in order to maximize the expressive power of film with the movie heyday, using the original negatives, incorporating more information to the hi-res scan in the first place. A 4K projector, pick up the traces of them, and 2K is overwhelmingly show me a different picture. 4K projectors when appeared honest, last fall, and there is a difference so far could not imagine.
Mr. Asakura: As one high-quality material, there is another 70mm IMAX film. Has been mixed by the chapter is 70mm "The Dark Knight," for example and 35mm, was caught the Grand Prix Grand Prix "Blu-ray" the first part of IDG been highly praised in particular parts of the 70mm film. However, the magnitude of the difference by showing 4K, it is larger and more "Eclipse" earlier in "The Sound of Music". Since the original IMAX film was considerably higher resolution and contrast even when downconverted to 2K, a kind of "overlap width" from 2K to 4K increase may be small it.
- Next time we will hear about the possibility of utilizing 21:9 playback 4K also, for the content of the current mainstream production 2K. |
