我们都知道,评价一款扫描仪主要从两个方面来考虑:一是扫描仪的质量,尤其是扫描仪的实际分辨率,二是扫描仪的扫描速度和易操作性,这两者都取决于扫描仪所采用的技术是否先进、过硬。除分辨率外,还有更能影响图像质量的因素。我们欣喜地看到hp scanJet 7400c扫描仪的问世,又将业界扫描仪产品带到了一个新高峰。 hp scanJet 7400c扫描仪光学系统的核心是一项全新的CCD技术,它创立了扫描仪性能的新标准。类似照相机中的胶片一样,CCD(光电耦合器)能够捕捉图像并将它转换成数字信息。其独有的双光敏原件设计缔造了业界领先的48位色彩深度,在每个CCD上
We all know that the evaluation of a scanner mainly from two aspects to consider: First, the quality of the scanner, especially the actual resolution of the scanner, the second is the scanner’s scanning speed and ease of operation, both of which depend on The technology used in the scanner is advanced and perfect. In addition to the resolution, there are more factors that can affect the image quality. We are delighted to see the advent of the hp scanJet 7400c scanner, which in turn brings industry scanners to a new heyday. The heart of the hp scanJet 7400c scanner optical system is a new CCD technology that sets the new standard in scanner performance. Like film in a camera, a CCD (Photo Coupler) captures an image and converts it into digital information. Its unique dual photo-active design creates the industry-leading 48-bit color depth on each CCD
