iPhone4影像性能有多好?問Imagination就知
 

【CTIMES/SmartAuto 籃貫銘 報導】   2010年06月09日 星期三

蘋果iPhone4昨日風光問世。除了更輕薄的工業設計外,其挑戰人類視網膜極限的螢幕更是主要賣點之一。然而,空有高解析的營幕顯示並不夠,如何在這麼高解析的畫面中提供順暢、精緻的影像,甚至是執行沒有延遲的3D遊戲才是關鍵。而對於達成這項需求,Imagination很有一套。

Imagination在3D影像方面已有長期的經驗與技術,能夠支援OpenGL等標準,同時也提供豐富的API支援,能夠對應Linux、Android、MeeGo、Palm WebOS、Symbian和微軟Microsoft等平台。
Imagination在3D影像方面已有長期的經驗與技術,能夠支援OpenGL等標準,同時也提供豐富的API支援,能夠對應Linux、Android、MeeGo、Palm WebOS、Symbian和微軟Microsoft等平台。

新的iPhone4與iPad相同,都是使用蘋果自行開發的A4處理器,這也是其進行影像處理與3D運算的主要核心。對於A4的技術架構,蘋果一直非常保密,但外界普遍猜測是使用ARM的Cortex-A8或A9多核處理器,至於影像處理器的部份則可能是ARM的Mali,或者Imagination的POWERVR繪圖處理核心。不過,蘋果在去年6月時,對Imagination的持股已大幅提升至9.5%,其目的何在,其實早已不言而喻。

對此,Imagination的PR總監David Harold表示,Imagination的POWERVR影像處理器的確被運用在iPhone4上,也就是A4核心中,但具體的型號則不方便透露。他指出,未來的智慧型手機對影像處理的需求非常龐大,下一代的手機影像性能甚至將高出目前的10倍左右,包含3D遊戲和影片等,都會成主流的手機應用。而Imagination在3D影像方面已有長期的經驗與技術,能夠支援OpenGL、OpenGL ES、OpenVG和CL等標準,同時也提供豐富的API支援,能夠對應Linux、Android、MeeGo、Palm WebOS、Symbian和微軟Microsoft等平台。

而在今日的台灣記者會上,Imagination除了展示一系列的技術應用外,也宣布推出可供嵌入式與行動裝置使用的POWERVR SGX544高性能繪圖核心。該核心為POWERVR Series5XT系列產品家族的第二個成員,可以搭載高性能四管線的單核心,或介於二至十六個核心(八至六十四管線)的多重處理器設計,並完全支援微軟Microsoft DirectX 9。

Imagination行銷副總裁Tony King-Smith表示,SGX544是以過去成功的MP多重處理器技術為基礎,並有五家授權客戶廠商。GX544還支援桌上型desktop OpenGL 2.1、OpenGL ES 1.1與2.0、OpenVG 1.1和OpenCL 1.1 Embedded Profile等標準,並通過了嚴苛的Khronos與Microsoft相容測試,可確保快速上市的業務要求,並適用於各式嵌入式與桌上型作業系統中。

Imagination Technologies為處理器IP供應商,可運用在繪圖、影像、多媒體、多執行緒的嵌入式處理器/ DSP中,以及多標準的通訊應用。目前台灣包含矽統、聯發科及瑞昱都是其授權客戶。

iPhone 5 傳6月6日現身

美國最大無線電信營運商威瑞森無線公司(Verizon Wireless)才開始販售CDMA版iPhone 4,業界就已盛傳蘋果將在6月初發表iPhone 5,分析師直指時間就在6月6日。

 

AppleBitch部落格上月率先披露,蘋果預定6月5日至9日在舊金山Moscone中心舉行的「企業會議」時發表新版iPhone。蘋果自2003年起一直在該地舉行全球開發商大會(WWDC),過去三年來WWDC都在6月第一周舉行,且都在會議的第一個周一發表新版iPhone,因此有分析師推估6月6日可能是iPhone 5問世之日。

 

蘋果過去四年來都在WWDC會議結束後的數周內讓iPhone上市,其中有三次上市時間為6月,只有2008年是在7月11日供應iPhone 3G。

 

不過AppleBitch說,蘋果也預定在5月10至11日、以及6月22至23日在 Moscone中心舉行「企業會議」,這兩個時間也可能是推出iPhone 5甚至是iPad 2的日子。蘋果過去大多在3月或4月宣布WWDC的日期。

 

蘋果以前每年夏天推出新一代iPhone,今年消費者都在討論,iPhone 5將維持長久以來由AT&T獨賣的GSM系統,還是會增加類似本周威瑞森將正式銷售的CDMA系統。

 

部分業界人士揣測,新一代iPhone可能採用與全球各地GSM和CDMA系統都相容的高通(Qualcomm)全球電話晶片。

 

因拆解蘋果產品而聲名大噪的科技網站iFixit披露,威瑞森銷售的CDMA版iPhone 4,已修正先前收訊不良的天線設計,且採用的晶片則來自高通,而非英飛凌(Infineon)。威瑞森已在3日開放預購iPhone 4,結束AT&T獨家銷售三年半的局面,10日起並將在威瑞森、蘋果商店以及百思買(Best Buy)、沃爾碼(WalMart)等實體商店開賣,售價199.99美元

 

分析師看好威瑞森加入iPhone銷售行列後將帶動蘋果銷售成長。Needham公司說,蘋果目前在全球智慧手機市占率為16%,預估將因此增加5個百分點,該公司並以iPhone和iPad銷售強勁為由調升蘋果股票目標價,從每股375美元上修至450美元。

Nikon Patent Could Lead to DSLR Moviemaking Dream Lens

Nikon Patent Could Lead to DSLR Moviemaking Dream LensSo you got a nice new DSLR for Christmas, and it can take impressive HD video too! That said, you'll probably notice that simultaneous zooming and refocusing is less than ideal. A new Nikon lens patent aims to fix that.

While such a lens is unsurprising, given the incredible interest in DSLR filmmaking these days, it is nevertheless very welcome (should it see the light of day).

Should the lens land in prosumers' hands, they can expect an experience that will involve a single lens that can zoom by hand (manual mode) or automatically in its movie/video-making mode. Again, such a lens is not surprising in the least, but it's still great to see Nikon R&D putting design to paper. [Egami via Nikon Rumors via Engadget]

Toshiba building new factory to churn out iPhone LCDs, says Nikkei

Word on the street -- and by that we mean a Nikkei Business Daily report -- is that Toshiba's dropping a cool 100 billion yen (around $1.2 billion in US currencies) for a new factory in the Ishikawa prefecture, Japan. Its raison d'être? Low-temperature polysilicon LCD panels, primarily for the iPhone (no indication on which version; Apple is said to be investing in a portion of the factory, as well). Construction begins early next year and production is apparently slated to commence in the second half. More than enough time to stockpile unicorn tears for the assembly line.

memory + Wi-Fi = Eye-Fi

http://www.eye.fi/how-it-works/basics

Eye-Fi View Quickly Shares Full-Resolution Photos With All Your Devices

In a hurry to share the full-resolution versions of your photos with several web-connected devices? Eye-Fi has a solution. Turns out that the company behind the wireless memory cards we know and love has a clever new photo-sharing service.

Basically all you'll do is log on to the Eye-Fi site and view your uploaded photos. You'll have the ability to share photos or albums with trusted contacts and to create download links. There's no charge for sharing photos uploaded to the site within a seven day window, but anything beyond that will require you to upgrade to a $50/year premium service.

VIEW AND SHARE DIGITAL MEMORIES ANYWHERE, ANYTIME WITH EYE-FI VIEW

New System and Email Feature Let People Quickly Show Off and Share Content on Multiple Devices

MOUNTAIN VIEW, Calif., October 27, 2010 - Eye-Fi Inc. (www.eye.fi), best known as makers of the world's first wireless memory card, today launched Eye-Fi View, giving consumers a new way to access their photos and videos from virtually any computer or mobile device. Along with Eye-Fi View, Eye-Fi also introduced a new email-sharing feature, allowing direct, private sharing of full-resolution images without clogging inboxes or requiring viewers to login.

"When we released the first Eye-Fi card three years ago, we solved the fundamental problem of getting pictures off the camera and onto computers and online sharing sites. As we enter the biggest photo-sharing season of the year – Halloween to Christmas – we're delivering an even easier way for people to view and share photos from any device, with more control than ever," said Jef Holove, President and CEO of Eye-Fi. "Photos and videos of the kids trick-or-treating can be easily emailed to grandma and shown off on dad's iPad"

When it comes to photography, viewing the images is the point, and more devices – from netbooks to smartphones to tablets – create more ways consumers want to view and show their memories. With Eye-Fi View, this content is now accessible from virtually any Internet connected device and can be viewed and shared at home, at the office, or on the road.

Whether selecting certain photos to share on public sites like Facebook or Flickr, or privately sharing several images or full albums with trusted email contacts, Eye-Fi makes it easy. By simply logging into their Eye-Fi account from any device, users can view photos, publish them on the web, or share them via email.

"There are many sites on which pictures and videos can be shared. But even in this age of social media, email remains the most popular method of sharing among consumers," added Holove. "With our unique approach to email sharing, Eye-Fi is extending its ease of use capabilities to customers who want to email their photos. Because, put simply, photos are created to view."

With Eye-Fi's email feature, users select contacts from their own address book, and recipients – whether Eye-Fi users or not – can easily download full-resolution images through a single link, without worrying about overwhelming their inbox.

Pricing and Availability

With the latest Eye-Fi Center release, Eye-Fi X2 card users can automatically send content to their Eye-Fi View. Access to content uploaded within the last seven days is always free. Upgrade to Eye-Fi Premium to maintain access to an unlimited amount of content for only $4.99 a month or $49.99 a year. All Eye-Fi users can take advantage of the new email sharing feature.

Eye-Fi products are now available at Wal-Mart stores nationwide. Wal-Mart is the latest national retailer to feature Eye-Fi, following the addition of Target earlier this year. Availability beyond electronics and photography outlets underscores the expanding consumer demand for Eye-Fi's unique solution. Additionally, Eye-Fi's international users can now subscribe to all Eye-Fi services including Eye-Fi Premium. For more information, visit www.eye.fi.

The World's Smallest Full HD Display

The World's Smallest Full HD Display

The iPhone 4's Retina Display is 3.5 inches, with a resolution of 960x640 and a pixel density of 326ppi. Pretty much everyone agrees it looks great. So how incredible must ORTUS's new 4.8-inch, 1,920×1080, 458ppi display look?

ORTUS, a collaborative venture between Casio and Toppan Printing, announced the Hyper Amorphous Silicon TFT (HAST) display today in Japan. The company claims it's up to 30% brighter than other TFT displays, capable of producing 16.8 million colors and has a viewing angle of 160 degrees.

But if the Retina Display, as Apple claims, is pushing up against the threshold for the human eye, is ORTUS's added pixel density really that important? I'm reserving judgment until I can watch Dark Knight on the thing. [CrunchGear]

seiko active-matrix epd watches offer 300dpi display

I’ve always got my eyes peeled for unique watches for you guys, and this is definitely one of the cooler high-tech timepieces I’ve seen in a while.

seiko_SDGA001_SDGA003_epd_watches

Seiko Japan’s new SDGA001, SDGA002 and SDGA003 watches feature the world’s first active matrix electrophoretic display (EPD). This display technology is similar to what you might find in a high-end e-reader, capable of producing sharp, 300 dot-per-inch images with a 180-degree viewing angle.

seiko_SDGA001_epd_watch

Thanks to the ultra high-res display, the watches can display time in a variety of fonts and on-screen styles – my personal favorite being the deck of cards style:

seiko_SDGA001_SDGA003_watch_fonts

The watches offer a 32-city world time capability, and can automatically be synchronized via radio signal. Each one comes in a sturdy stainless steel case, with a durable sapphire crystal. Battery power is recharged through an integral solar panel, offering about 30 months of display time on a full charge. There’s also LED illumination for viewing the time in darkened rooms.

Prices for the watches range from ¥94,500 to ¥105,000 (appx. $1127 to $1253 USD), so unless you’re loaded, you’re going to want to wait for the 2nd or 3rd generation versions before you start cashing your dollars for yen.
