Sony whinging about Nokia 808 PureView as not new Tech?




According to TechRadar, Sony is yet another company trying to put down the Nokia 808 PureView. I love your products too, Sony, but this sounds like whining. Just give credit where its due.

It’s quite clear it’s a development announcement more than a retailable proposition, the technology is not new, it’s only what our cameras have done for about a year now

For about a year? PureView has been in development for 5 years. Whilst pixel binning is not new, Sony, please tell me who else has put this combination of imaging together yet on a phone? Perhaps your point and shoots. Come on, if it’s been around for a year, where is your equivalent? Xperia what? Xperia Duntexist?
Sony goes on to say it’s just a technological announcement, not a retail solution. What does that even mean? The product is right there and will appear in a couple of months. Maybe it’s not a plausible retail solution for you, Sony?

But, it is still only a technological announcement, it’s not a plausible retail solution yet.

Oh well, no one really cares what Sony thinks. No one ever cares when someone says “we’ve been doing that for years” as clearly they haven’t done it quite right enough for people to pay attention. We Nokia fans should know as we say that often about other products. Sony: make something better than PureView’s camera for your mobiles and then talk.
Tech Radar points out many are quick to denounce the Nokia 808 PureView’s technology. Yup, that’s the key word right there. Quick. Quick and ignorant to what PureView actually does. I don’t need to explain it all over again of course as results are speaking for themselves. Touched yet another nerve ?It’s not about Technology – it’s what you do with it!
(Very pleased to say that from a genuinely Nokia pro perspective as opposed to them not getting their own slogan)

大家有何看法?
應該是因為最近大家都在說SONY只會灌畫素,畫質糊得像油畫,然後又一直被拿來和NOKIA比較所以惱怒吧~~SONY呀SONY與其說風涼話,不如好好的改善畫質吧~~買CYBER-SHOT相機只附贈一堆取了亂七八糟名字的技術,品質也越來越差...哀。
現在808到底是不是成功的產品確實還未可知
之前那幾張樣照都是iso69的產物,為何不演示高iso表現?
前幾天吵得沸沸揚揚的是2400萬畫素APS-C的NEX7
被指出鏡頭素質無法吃下那麼大的畫素(邊緣死)
那麼808的鏡頭不曉得能否滿足它的1/1.2" 41MP
另在,它沒有OIS,數位防手震?
據我所知一般數位防抖的作法是拉高ISO來得到更快的快門
如果高感不OK,那麼低光可用度將非常的低,模糊/雜訊二選一
我知道文章內在強調的是PUREVIEW技術,真的有很厲害?
它原生就是4100萬畫素的RAW檔,即使超取樣組成優質的低畫素JPEG
但41MP高感光度的RAW想必雜訊、細節很慘,會因此處理得到改善嗎?

再來之前官光方說法似乎語帶保留
The maximum ISO is not yet confirmed, but expect it to be impressive!
-希望很棒
he optics and lenses are co-developed by Nokia and Carl Zeiss, but not the sensor.
-和蔡斯一起開發卻不說是誰生產、用料鍍膜?感光原件也不知誰是做的

SONY我覺得還算蠻有立場發聲的
畢竟它手機、攝影機、相機、感光元件都有做
不過打擊對手也是事實,只能期待808上市後會讓他閉嘴
(他最新那顆1800萬1/2.33的CMOS很油畫是真的)

我覺得sony也不要在意,相機不光是只有鏡頭和感光原件的大小而已,808的光圈、快門、測光模式、Iso值都不可調,再怎麼厲害也不過是照相手機。
SONY說自己早就有...不拿出來放在手機上賣是有屁用= =?
業界一定有許多技術是早就存在的,但是你沒有導入商品內在user的眼中就是沒有!
SONY相機真的不錯,但SE跟SONY的手機相機卻...
而且SONY拿真的相機來砲手機的相機自己都不覺得好笑嗎...

虧我對SONY的品牌印象不錯,沒想到這次竟然也說出這麼無腦的話...

唯一的解釋就是...Nokia 808真的讓DC感受到不安了...

相機界早就停止畫素戰爭了

你要賣可以 但是對手不一定跟

Canon 5D3跟1Dx就是最好的例子 不隨對手起舞



高畫素的噱頭就是騙騙外行人而已,不然充其量就是照片佔容量、佔傳輸頻寬

大家都有本事塞四千萬畫素

只是沒想到這梗先被Nokia拿來用 SE酸葡萄心理吧

不是這樣吧...
這東西是有利於無損數位變焦的,而SONY的DC確實很早就說他們有無損數位變焦了~只是事實就是SONY一直沒導入到手機內
索尼說他們已經使用pixel binning(像素融合)這項技術快將近1年了
It’s quite clear it’s a development announcement more than a retailable proposition, the technology is not new, it’s only what our cameras have done for about a year now
我們知道PureView其實也是在這基礎下發展出來的

我突然想起一件事情
就是以前n8推出的時候曾經閱讀過一些文章
依稀記得有提過pixel binning相關訊息
在網上搜尋了一下果不其然讓我找到了
Through the downscaling and binning process from the 4000×3000 pixel sensor to 1280×720 video pixels, any visual noise that may have required some degree of noise reduction is effectively filtered out, therefore allowing us to process the video with noise reduction disabled. This means in reasonable lighting you won’t see any noise in the video during play back. This has allowed us to retain incredible levels of detail rather than losing it to noise reduction. It’s also allowed us to implement digital zoom which is virtually as good as optical zoom
(來源)

原來pixel binning早就已經在N8的時候就開始使用了, 不過當時是用在影片上
現在重點來了
我們姑且不論是誰先把這技術用在照片或影片上
而是誰先使用這項技術
請大家回想一下
索尼號稱自己已經使用了快一年, 注意, 是"快一年"
可是N8是什麼時候出來的呢? 呵呵
更別論PureView技術已經開發5年時間了
差別在於這次的808大肆的宣傳PureView這項技術而當年的n8卻沒有(可能只是試水階段而已, 沒什麼好宣揚的)
所以這技術到底是誰先開始使用的
答案已經呼之欲出了
連對手的東西都還未釐清就急著給自己冠上先驅的名號?
索尼算是搬石頭砸自己的腳嗎

我看你又是一個未了解PureView技術的訴求是什麼就亂下定論的人吧
再說一次了
4100萬像素並不是這次808的重點
而是如何去善用這些畫素去達到高水準的畫質

誰都有本事做出來?
那為什麼到目前為止沒見到消費型DC有什麼大突破?
現在反而讓一家手機製造商給超前了?
這真的只是一個梗而已嗎?
索尼不是最近才有一支什麼1800萬 1/2.33"ccd的型號出來, 可是畫質卻被人批評?
這不是在打畫素戰是什麼?

乾啦! 來看看 N8 的 Pure View 餘興一下...
