  1. 12th forum for digitization in museums第12届博物馆数字化推广论坛 Practical museums applications for digital data acquisition of extremely large pictures and wall paintings博物馆行业在超大尺寸书画和壁画的数字数据采集工作中的一些实际应用

  2. 企业历程 History 德国CRUSE公司自1979年在波恩和科隆附近城市莱茵巴赫成立， 一直为行业高端客户研发和制造高分辨率的大型图像设备. Since 1979 CRUSE GmbH, located in Reihnbach, Germany (near Boon and Cologne), has been developing and producing equipment to record large sized originals in premium quality to meet our clients´ high demands. 借助于严格处理过的线型CCD、均匀光源、统一锐度和复制角度， CRUSE扫描仪完成了完美的图像抓取，也成为在大型稿件成像业 界中最专业、最先进的公司。 CRUSE scanners are far superior to the photography of large size original s, thanks to their image capture with alinear CCD in strictly controlled, homogenous light conditions, and with consistent sharpness and reproduction angle. 严格按照客户想法和需求，所有CRUSE扫描仪均在德国进行设计 和制造，CRUSE扫描仪在扫描和复制行业中享极高的名誉，目前 640台CRUSE扫描仪在全世界33个国家服务使用 Each and every CRUSE scanner is constructed in Germany individually, according to the requirements of each customerand therefore is built exclusively to our customers´ needs. This defines CRUSE quality as the international benchmark for the scanning and reproduction of large size originals – with over 640 CRUSE scanners installed in more than 33 countries worldwide. 因此也成为那些来自博物馆、文献机构、 制版、装饰、地板、墙纸、瓷砖、纺织、 印刷和包装工业的客户首选的产品 CRUSE therefore is an excellent partner for archives, fine art printers, repro houses, design houses, libraries, décor-, laminate-, wallpaper-, ceramic-, textile-, pre-press, and packaging industries, as well as museums, land registries, and survey offices. .

  3. 代表客户 References CRUSE公司的部分客户 Some of our clients are: 美国洛杉矶保罗·盖蒂博物馆 J. Paul Getty Museum, Los Angeles, USA 北京故宫博物院 Palace Museum ， Beijing, P.R. of China 埃及亚历山大城图书馆 Bibliotheca Alexandria, Egypt 英国剑桥大学 Cambridge University，UK 美国国家航空航天局（美国太空总署） NASA (National Aeronautics and Space Administration) in Houston, TX, USA 美国国家档案馆，华盛顿特区 National Archives，Washington, DC.

  4. 独占鳌头 Why is CRUSE so unique? CRUSE扫描仪通过下列关键技术独占鳌头： The uniqueness of Cruse ST scanners can be defined through the following key features: 1. 可调至1200PPI的极致精度 Extremely even and precise scanning with variable resolution up to 1200 ppi (optical resolution) 2. 提供多种可变光模式、扫描原件尺寸可达2米x 3米 Different models for originals up to 200 x 300 cm original size 3. 非常均匀甚至绝对稳定的照明 Very homogenous, even and stable light exposure 4. 线平行扫描: 全幅面原稿范围内,以最大锐度和100%色彩均匀度扫描 通过CCD(RGB)进行逐线获得精准自然的图像 Parallel scanning result: maximum sharpness and 100% parallelism for even the largest originals. Line by line capturing via CCD(RGB) for accurate and natural results 5. 基于ICC规范的色彩管理，全世界最先进的色彩特性， ICC based color management. Best color truth of the world according Getty Advanced profiling 6. 完全的无接触扫描 Totally “touch -free” , non contact scanning 7. 实用功能：可对框高12厘米以上的图片和原稿进行扫描 Multifunctional: scanning of framed pictures and originals with a frame height of up to 12cm and more 8. 可创建3D立体机理效果(2D扫描模式下) We create a three dimensional plastic TXTURE Effect(2D scan) 9.

  27. CRUSE专业色彩管理:专业级 CRUSE Color Management: Expert Opinions 色彩管理 Color management “实验中采用了五套不同的照相（扫描）系统以便分析颜色精度等·····， 只有制造商A和CRUSE系统能提供可以接受的颜色结果以及成功优化的档案图片.当CRUSE系统对高色度色彩发出极端色调警报时，制造商A的系统也会产生自发光效果的图像。对档案色彩图像而言，这两种系统都是值得推荐使用的·····” -罗伊·伯恩，（罗切斯特科技学院）-史丹利·史密斯（保罗·盖蒂博物馆） “Experiments were performed to analyze the color accuracy of five camera systems used for museum image-archiving applications [...] Only the [experimental RIT multispectral] and Cruse systems produced acceptable results, systems optimized for archival imaging. The [Brand A] system produced self-luminous appearing images while [Brand B] had severe tone reproduction error for high-chroma colors. Both of these new systems would require considerable visual editing to produce archival color images.” Roy S. Berns, Rochester Institute of Technology, and Stanley Smith, J.
