HP ScanJet 6100C彩色平板式扫描仪近日在中国市场露面。HP在引入新机型的同时,还引入了衡量扫描仪性能的若干新概念。HP ScanJet 6100C的光学分辩率为600dpi;最高插值分辩率可达2400dpi。在600dpi时,其扫描速度可达4.56ms/Iine。另外,该扫描仪配有扫描幻灯片用的工具附件,并兼容多种著名的专业图像软件,还可用于建立动态网页。HP的有关专家在演示新机型时,特别引入了一个可以更加准确地扫描仪分辩率的概念ppi。ppi与以往很多厂家所宣传的dpi的不同之处在于它衡量的是每英寸象素的数目而不是点数。据HP专家介绍,除分辩率外,另一个衡量扫描仪性能的重要指标是MTF(modulation Transfer Function)。MTF值越高,则表明该扫描仪对图像调节的处理能力越强。
HP ScanJet 6100C color flatbed scanner recently appeared in the Chinese market. While introducing new models, HP introduced several new concepts for measuring scanner performance. HP ScanJet 6100C optical resolution of 600dpi; maximum interpolation resolution of up to 2400dpi. At 600dpi, the scanning speed of up to 4.56ms / Iine. In addition, the scanner comes with a tool attachment for scanning slides and is compatible with a variety of well-known professional image software and can also be used to create dynamic web pages. When demonstrating a new model, HP’s experts introduced a concept ppi that provides more accurate scanner resolution. The difference between ppi and dpi advertised by many manufacturers in the past is that it measures the number of pixels per inch rather than the number of dots. According to HP experts, in addition to resolution, another important measure of scanner performance is MTF (modulation Transfer Function). The higher the MTF value, the stronger the scanner’s ability to handle image adjustments.
