彩色扫描仪

 

彩色扫描仪转换成电子的位图图像可以由计算机使用的照片,幻灯片,和艺术品。 The bitmap images can be scaled and rotated during the scan.位图图像可以缩放和旋转扫描过程中。 After the scan, they can be also be scaled (to a minimum) and rotated or color corrected in an image editing program such as Adobe Photoshop?.扫描结束后,他们可以也可以缩小到最低限度,旋转或色彩校正在图像编辑程序,如Adobe Photoshop?。

Almost any type of original can be scanned, including photographs, negatives, transparencies, artwork, previously printed materials, and text.可以扫描几乎所有的原始类型,包括照片,底片,胶片,艺术品,以前的印刷材料,和文字。 The text scanning requires an OCR (optical character recognition) program.文本扫描需要一个OCR (光学字符识别)方案。 Scanners are available in several different sizes ranging from a small hand-held model to the large drum scanners.扫描仪是在几个不同大小的范围从一个小型的手持式模型的大型滚筒扫描仪。 If you need to scan images larger than the scanner will allow, scan it in pieces and then stitch it together in an image editing program.如果您需要扫描超过扫描仪的图像将允许,扫描件,然后缝在一个图像编辑程序一起。

Different types of scanners provide output of different quality ranging from the low-end, inexpensive scanner, to the high-end, expensive professional scanner that can cost several thousand dollars.不同类型的扫描仪提供不同质量的输出,从低端,廉价的扫描仪,高端,昂贵的专业扫描仪,可以花费数千元不等。 The low-end scanner may work well for Web, newspaper, and "For Position Only" (FPO) design/layout images to be replaced later by a high-resolution scan.低端扫描仪以及可能的工作网络,报纸,“位置”(自由党)设计/布局被取代了高分辨率扫描后的图像。 The high-end scanners are generally placed in service bureaus and printing companies where high quality images are commonly provided.高端扫描仪一般都放置在服务部门和印刷企业普遍提供高质量的图像。

Note: Any image editing you do to a FPO image will not automatically be carried over to the high-resolution image. 注:任何图像编辑你做一个自由党的形象,将不会自动进行高分辨率图像。 The changes will also have to be edited on the high-resolution image.的变化也将是对高分辨率图像编辑。

The key factors for providing high quality scanned images are dynamic range, resolution, quality of optics, the light source, the number of bits per color, and aperture.提供高品质的扫描图像的关键因素是光学动态范围,分辨率,质量,光源,数位每色的,和光圈。
