摘要

本文给出了光到光视频传输路径可能达到的清晰度水平的估计，这可以被认为是理想的，即仅由于相机镜头的衍射限制以及相机矩阵传感器和再现显示器的变换元件的有限尺寸而发生清晰度下降，而无需额外的图像处理。给出了SDTV、HDTV、UHDTV 4K和UNDTV 8K系统的端到端MTF示例，其中考虑了再现显示引入的畸变，并对镜头和相机传感器的指定参数进行了分析。

POTENTIALLY ACHIEVABLE LEVEL IMAGE DEFINITION IN VIDEO APPLICATIONS

The paper gives an estimate of the potentially achievable level of definition for light-to-light video transmission path, which can be considered as ideal, i.e. such that a decrease in definition in it occurs only due to the diffraction limitations of the camera lens and the finite dimensions of the transforming elements of the camera matrix sensor and of the reproducing display without additional image processing. Examples of MTF of end-to-end paths for SDTV, HDTV, UHDTV 4K and UNDTV 8K systems for the specified parameters of the lens and camera sensor, taking into account the distortions introduced by the reproducing display, are presented.
