【摘要】 数字影像取代传统影像是以数字技术的发展为前提的,数字技术对传统技术的冲击带来了数字影像技术发展壮大的同时,也引出了影像科学理论上的新问题。如何对数字影像质量,尤其是技术质量进行科学的评价和界定,在目前的理论界有着非常重要的意义。本文从影调再现、细部再现、彩色再现三个方面对数字影像的技术质量进行了较为系统的梳理和分析。更多还原

【Abstract】 The traditional image replacing by digital image was premised on the development of digital technology.Traditional technologies brought the impact of development and growth of digital imaging technology,it also raised new problems in theory of imaging science.How to evaluate the digital image quality,especially in the scientific evaluation of technical quality and defination had a very important significance in the present theory sector.In this paper,image tone reproduction,detail reproduction and color reproduction of the technical quality of digital images were systematically combined and analysed.更多还原
