图像产品的测试是相当专业的工作,在工业生产上,图像品质可以量化到加以测量,但是这种量化的方式,牵涉到许多复杂的数学问题,远非一般仅仅喜爱摄影,或者没有受过专业训练的人所能精确测量。因此衡量图像品质的专业人员,本身必须具备相当高的专业知识。必须在这些专业知识的引导下,思考一切图像品质的实际需求,然后才能够制订出一套适合的检验方式,检验的结果才能客观而公正。我们本着图像光学专业的态度及知识,为读者制作这次的采购特集,主要的目的在于告诉读者哪些扫描仪是属于功能较佳的扫描仪;其次对于送测的扫描仪提出最佳的图像调整方案,最后,希望能提供扫描仪制造厂品质改进的根据。通过这三个目的的规划,我们不仅要找到哪一台扫描仪比较好,还要告诉购买者如何调整这些扫描仪所扫描的图片,并且希望这些测试的结果能作为各大厂商品质改善的根据。
The testing of image products is quite professional work. In industrial production, the image quality can be quantified and measured. However, this quantitative method involves many complicated mathematical problems, far from the general preference of photography or the lack of professional training People can accurately measure. Therefore, professionals who measure the image quality must have a very high level of expertise in their own right. Under the guidance of these professional knowledge, we must think about the actual needs of all image quality before we can formulate a suitable test method so that the result of the test can be objective and fair. We have the image of optical professional attitude and knowledge for readers to make this purchase feature, the main purpose is to tell readers which scanners are better features of the scanner; followed by the scanner to send the best test image Adjust the program, and finally, hoping to provide a basis for scanner factory quality improvement. Through these three goals, we not only find out which scanner is better, but also tell the buyer how to adjust the images scanned by these scanners and hope that the results of these tests will serve as a basis for improving the quality of the major manufacturers .
