DS200IIBDG1AEA燃機電氣模塊
開發(fā)了A400系列我們的目標是提供高性能相機，以滿足分辨率、速度和圖像質量方面最嚴格的要求。這一目標是通過使用一個精密的400萬像素傳感器和一個獨特的相機后端實現(xiàn)的，這兩個傳感器的結合提供了出色的圖像質量和快速預處理的可能性。為了確?？煽俊⒁恢碌馁|量，A400變體經(jīng)過100%的質量檢查和校準。所有這些都使得A400相機在許多應用中都非常靈活和可靠。所有A400攝像頭都包含一個高質量CMOS傳感器，具有2352 x 1726個活動像素。雖然最常見的CCD傳感器的速度限制為每秒15幀，A400變種提供卓越的最大幀速率：?A402k/kc-全分辨率24 fps?A403k/kc-全分辨率48 fps?A304k/kc-全分辨率96 fps?A2 320 x 1726時A405k/kc/167 fps?2 320 x 172時A406k/kc-209 fps A400系列在性能和圖像質量方面樹立了一個新的卓越標準，可與CCD相機匹敵。卓越的圖像質量得益于先進的CMOS傳感器和復雜的電子設計。三種不同的圖像增強功能可以進一步提高圖像質量：?柱陰影校正以消除固定圖案噪聲?DSNU陰影校正以去除暗信號不均勻性?PRNU陰影矯正以消除光響應不均勻性。與配備CCD傳感器的相機相比，無暈染或拖影是另一個優(yōu)勢。缺少代碼不是A400的問題，圖像在這方面非常一致。A400相機中使用的快速FPGA允許選擇機載預處理，并允許實施適合客戶要求的單獨算法
AOI功能、AOI列表和AOI編輯器
當使用A400相機上的感興趣區(qū)域（AOI）功能時，只有圖像的指定部分會從相機中傳輸出去。這會減少攝像頭傳輸?shù)臄?shù)據(jù)量，并增加最大允許幀速率。在A400相機上，可以在AOI列表中定義一組單獨的AOI。每個AOI都可以有不同的參數(shù)設置，例如AOI位置、AOI尺寸、曝光時間和閃光激活。生成的AOI參數(shù)集可以保存在相機中，并在內(nèi)部執(zhí)行。這意味著，從一組AOI參數(shù)更改為另一組參數(shù)時，無需使用慢速串行通信端口，這樣可以在操作期間提高幀速率。AOI編輯器軟件工具使創(chuàng)建AOI列表變得簡單。使用這個易于使用的工具，列表中的每個AOI都是以圖形方式創(chuàng)建的，方法是使用捕獲的圖像將AOI定位在最感興趣的區(qū)域并調(diào)整其大小。AOI列表是自動創(chuàng)建的，它概述了列表中每個AOI的位置、大小、曝光時間、延遲時間和閃光激活。該程序突出顯示任何不正確的設置，并提供糾正所需的信息。A400相機在PCB檢測等經(jīng)常使用AOI功能的應用中特別有用。裸板檢查和平板顯示器檢查也是需要A400卓越圖像質量和高速的應用。晶片檢驗、鍵合檢驗、芯片放置和封裝都是半導體市場的典型應用。其他應用包括三維測量、文檔處理、郵政和文檔排序。
The A400 series was developed
with the goal of offering a high performance camera to meet the most stringent requirements in terms of resolution, speed, and image quality. This goal was realized by using a sophisticated four megapixel sensor and a unique camera backend, a combination which provides brilliant image quality and the possibility of fast preprocessing. To ensure reliable, consistent quality, A400 variants are 100% quality checked and calibrated. All of this makes A400 cameras exceptionally flexible and reliable tools for many applications.All A400 cameras contain a high quality CMOS sensor with 2352 x 1726 active pixels. While the speeds of the most common CCD sensors are limited to 15 fps, A400 variants offer superior maximum frame rates: ? A402k/kc - 24 fps at full resolution ? A403k/kc - 48 fps at full resolution ? A404k/kc - 96 fps at full resolution ? A405k/kc - 167 fps at 2320 x 1726 ? A406k/kc - 209 fps at 2320 x 1726 The A400 family sets a new standard of excellence with performance and image quality that rivals CCD cameras. The extraordinary image quality results from the use of advanced CMOS sensors and sophisticated electronic design. And three different image enhancement features can improve image quality even more: ? Column shading correction to eliminate fixed pattern noise ? DSNU shading correction to eliminate dark signal non-uniformity ? PRNU shading correction to eliminate photo response non-uniformity The absence of blooming or smear represents another advantage over cameras with CCD sensors. Missing codes are not an issue for the A400 and the images are very homogeneous in this respect. The fast FPGA used in A400 cameras enables the option of onboard preprocessing and allows the implementation of individual algorithms adapted to customer requirements.
The AOI Feature, AOI Lists, and the AOI Editor
When the area of interest (AOI) feature on an A400 camera is used, only a designated portion of the image will be transmitted out of the camera. This reduces the amount of data transmitted by the camera and increases the maximum allowed frame rate. On A400 cameras, a set of individual AOIs can be defined in an AOI list. Each individual AOI can have different parameter settings such as AOI position, AOI dimensions, exposure time, and flash activation. The resulting sets of AOI parameters can be saved in the camera and executed internally. This means that the slow serial communication port is not needed to change from one set of AOI parameters to another and this allows higher frame rates during operation. The AOI editor software tool makes creating an AOI list simple. With this easy-to-use tool, each AOI in the list is created in a graphical way by using a captured image to position the AOI in the most interesting region and to adjust its size. The AOI list is automatically created, and it gives an overview of the positions, sizes, exposure times, delay times, and flash activation for each AOI in the list. The program highlights any incorrect settings and provides the information needed to make corrections.A400 cameras are particularly useful in applications such as PCB inspection where the AOI feature is often used. Bare board inspection and flat panel display inspection are also applications where the A400‘s superior image quality and high speed are both required. Wafer inspection, bonding inspection, die placement, and packaging are all typical applications in the semiconductor market. Other applications include 3D measurement, document processing, and postal and document sorting.
