智慧手機紅 影像處理領域必佈局的四大商機

雖然天線設計與收訊功能紛擾未解,但第四代iPhone受人矚目的高畫質視訊功能已是定局。同時揭示了行動裝置普及帶動消費者對於視訊功能的期待改變,他們要求「隨時,隨地,觀賞隨意格式的影片」,替影像處理領域帶來新的商機,集中於時脈控制器、影像處理器,以及音訊編解碼器與ASSP。

根據研究機構iSuppli報告,全球智慧型手機出貨量將從今年的2億3900萬支,成長為2013年的4億3900萬支,成長幅度驚人。IDT總裁暨執行長Theodore Tewksbury表示,影像處理領域的挑戰與商機來自於數位內容開始被跨裝置瀏覽。

為了利於傳輸,經壓縮的視訊內容必須再經解壓縮程序,一來一往過程往往產生雜訊而折損影像品質。如果只是要滿足行動裝置需求,可能使用低品質的壓縮技術即可解決;但若要同時滿足行動裝置與大型顯示器,情況就完全不同,因為在大型裝置上,雜訊會被放大,對於習慣用大型裝置如電視觀賞高畫質節目的觀眾而言,產生極大的落差。也因此,Theodore Tewksbury說,從時脈控制器到影像處理器,都是商機所在。

而對於音訊商來說,行動裝置原先對於音訊品質的要求不至於太高;但是隨著視訊角色愈趨吃重,如何在行動裝置忠實呈現原始的音效?音訊編解碼器與ASSP的成長都值得預期。

對照研究機構Gartner所發布的統計數據中,無論在金融海嘯威脅下的2009年或是緩步復甦的2010年,ASSP都是對於整個半導體產業營收貢獻比例最高的產品,分別為2009年的27.5%與隔年的25.9%。在2010年的稍有下滑,則來自於記憶體的強勁成長力道所造成。

A Flip-Like Pocket Cam From Sanyo Does 1080p At 30FPS

A Flip-Like Pocket Cam From Sanyo Does 1080p At 30FPS

Sanyo, long-time expert in making small but powerful dual cameras (video + still), just made its first Flip-type camera. Yes! It not only has Sanyo's expertise, it also has a 3X optical zoom and dual-mics that look like shoulder pads.

The price for the VPC-PD2BK is only $170 (right in line with the rest of the pocket cameras), and can do 1080P at 30FPS. It takes 10-megapixel photos, stereo sound recording, flash, SD/SDHC/SDXC card compatible, measures 2.48 x 0.87 x 4.36 and weighs 3.7 ounces. The 3X optical zoom also sets it apart, even if it does make the back look a bit unbalanced and cyborgy.

That Sanyo is getting into the cheaper camcorder space is exciting, even if the space is slowly being squeezed out by higher and higher quality smartphone video recording. Even still, it's going to be a while before you can get this level of quality on a smartphone. [Sanyo]

Even Karate-Mad Hermits Can't Resist Owning Cellphones In Japan

Even Karate-Mad Hermits Can't Resist Owning Cellphones In JapanI thought hermits kept busy plastering windows with newspaper and collecting Pot Noodle cups. This Japanese hermit, while burying himself in the hills and practicing nunchuck skillz, has his own website and answers phonecalls—while being interviewed on TV.

At 68 years of age, the Japanese hermit moves faster and has better eyesight than any of us, probably due to the fact he is a former karate champ. 16 years ago he moved to the Aichi prefecture of Japan to become a hermit, but as shown in this crazy Japanese TV segment about him, he just can't give up communicating with the outside world. I feel his pain. [Heiseisennin via Japan Probe]

購買智慧手機,我個人的先決條件是收發訊及網路要暢通,這是手機溝通與雲端運算的必要條件,其次才是Panel的影像品質與造型設計問題,如HTC與Nokia的天線收發訊號品質就不錯!!而iPad我倒希望有iPhone 4 Panel的影像品質.
