諾基亞Lumia 1020

諾基亞Lumia 1020是一款諾基亞2013年7月11日釋出的以Windows Phone 8平臺所開發的智慧型手機。它擁有一個支援拍攝4100萬畫素相片的卡爾蔡司認證鏡頭，透過諾基亞研發的超取樣，再加上(Back-illuminated sensor)，把七個畫素點歸一，令相片質素提升至最清晰地步。Lumia 1020是繼諾基亞808 PureView之後的諾基亞新一代拍攝機王。命名方式.在Lumia 1020的設定中的關於介面內顯示手機型號為諾基亞 909，與同樣主打攝影功能的諾基亞 808 PureView有著相同的命名方式。PureView Pro 相機技術.PureView是使用於Lumia 1020的影像技術。它使用高達4100 萬畫素、1/1.5"，並搭配 Carl Zeiss 鏡頭組的感光元件。此技術支援畫素超取樣，也就是將周圍的許多畫素合併為單一畫素。 PureView影像技術提供優良的影像品質、無損數位變焦，及在低光源環境下提升效能。它的數位變焦捨棄幾乎絕大多數智慧型手機常用的插補點技術。在拍攝相片及錄製影片的時候，該技術在較低的影像輸出尺寸下提供更好的變焦品質，能夠在錄製1080p的全高畫質影片時提供4倍無損變焦，或是在720p的錄影解析度提供6倍變焦。光學防手震能夠在拍攝相片及影片時抑制手持晃動的模糊現象，而且也可在低光源環境下以光學防手震延長快門開啟時間，提供更好的品質。有些評論者指出Lumia 1020的相機在某些特定狀況可能會發生鏡頭耀光及白平衡失常的現象。而Lumia 1020的相機啟動時間為6.1秒，500萬畫素相片的拍攝處理時間為3.6秒，3800萬畫素的拍攝處理時間則是4.2秒。PureView Pro 規格.Nokia Lumia 1020搭載了4130萬畫素背照式CMOS感光元件，尺寸為1/1.5吋。單一畫素尺寸為1.12微米，元件尺寸為8.80×6.60毫米，焦距轉換率為3.93×35mm，16:9等效焦長為25mm，4:3的等效焦長為27mm，光圈為2.2。Nokia 808 Pureview搭載4130萬畫素CMOS感光元件，尺寸為 1/1.2 吋，總畫素為7728×5368。取決於使用者的拍攝長寬比，在預設的相機軟體的16:9影像尺寸為7728×4354畫素的相片。單一畫素尺寸為1.4µm，元件尺寸為10.67×8.00毫米，焦距轉換率為3.2×35mm的16:9等效焦長為26mm，4:3則是28mm，光圈為2.4。光圈為2.2的單群6枚鏡片Carl Zeiss 鏡頭。焦距為 7.2 mm，35mm的16:9 等效焦長為25mm，4:3的等效焦長為27mm。所有鏡片皆採非球面鏡片，其中一枚使用高折射率低色散非球面玻璃鏡片。光學防手震—使用新型的滾珠位移作動方式，擁有良好的位移量，也增加鏡頭模組的組裝複雜度。使用低延遲機械快門，快門開啟長度為1/16000秒至4秒。採用支援超取樣及無損變焦的整合式影像處理器，並搭載每秒可處理超過10億畫素的整合式影音處理器，在錄製全高畫質影片時能做到四倍無損變焦，並且降在低雜訊及提升動態範圍。評論.知道您的小工具：「Nokia Lumia 1020 is a great improvement over the Nokia 808. The camera is just superb and one of the best we have seen on a mobile device. If you need a simple smartphone and your phone doubles as your point and shoot, this is the device for you.」的布賴恩·克盧格：「I think it’s fair to say that once again Nokia has basically set the bar for the rest of the smartphone imaging world – in terms of both hardware and software features.」美國雜誌Finnamore的評論家克里斯：「Simply stunning photos make the Lumia 1020 the ultimate cameraphone.He gave it five stars and awarded it the Expert Reviews: Ultimate award, which places it among other high-end flagships such as the Galaxy S4 and the iPhone 5S, which also received the award.」網站的艾琳洛：「Despite the lower lighting level, the Nokia is able to out-perform its rivals by a healthy margin. Fine detail is better maintained and the image is generally "cleaner." This benefit (that comes from a combination of a larger sensor and the noise-reducing effect of downscaling images), is one of the significant advantages of Nokia's decision to use a large sensor in a smartphone. Whether you look at the resolution stripe on the left of the image or the etched portrait on the right, the 1020 is significantly out-performing its rivals.」The Verge的大衛·皮爾斯則評論道：「this is a remarkable phone, hampered by its operating system.」科技新時代的Dan Nosowitz：「Nokia's new Lumia smartphone has amazing hardware (especially its unprecedented 41-megapixel camera). And it doesn't matter at all, because its software lags so far behind its hardware.」衛報的查爾斯·亞瑟：「The Finnish phone maker released its remarkable Lumia 1020 phone with a 41-megapixel camera - but it's still missing native apps for low-quality Instagram, Vine and Snapchat」的吉姆·費舍爾：「The Lumia 1020 is a big step forward for camera phones, but the step isn't complete. Nokia's sensor and lens advances must be paired with a CPU and image processor fast enough to make shooting effortless, and Windows Phone's creative app gaps need to be filled in.」Gadgetmania網站的一位評論家：「If you absolutely need the best camera on a smartphone and don’t mind Windows Phone 8 and spending a good chunk of money upfront, the Lumia 1020 is worth looking at, but I don’t expect it to be very popular.」問題報告.有些使用者報告Lumia 1020電池消耗過快和容易發熱，隨後則會自動重新開機或處於宕機狀態，而且其語音通話和WiFi質量也未如理想。在微軟釋出Windows Phone 8.1更新後也為Lumia 1020帶來一些問題，包括手機可能會隨機停機。不過，微軟後來已經解決了該問題。流行文化.Lumia 1020曾經出現在多個MV和電影中，其中包括：
