DEFOCUS在英语中的意思是什么?

散焦像差

在光学中,散焦是图像简单地失焦的像差。 任何使用相机,摄像机,显微镜,望远镜或双筒望远镜的人都很熟悉这种差异。 在光学上,散焦是指沿着光轴离开最佳焦点的平面或表面的平移。 一般来说,散焦会降低图像的清晰度和对比度。 什么应该是锋利的,高对比度的边缘在场景中逐渐过渡。 场景中的细节很模糊,甚至变得隐形。 几乎所有的图像形成光学装置都融合了某种形式的焦点调整,以减少散焦和最大化图像质量。 对于给定的聚焦偏移量,图像模糊程度与镜头f数量成反比。 低f值,如f / 1.4至f / 2.8,对散焦非常敏感,并且具有非常浅的焦点深度。 在f / 16至f / 32范围内的高f数高度耐散焦,因此具有较大的焦点深度。 f值中的限制情况是针孔摄像机,可能在f / 100到f / 1000的范围内工作,在这种情况下,所有物体几乎不受距离针孔的影响。

在英语 词典里defocus的定义

字典中散焦的定义是失去焦点。 其他离焦的定义是使焦点不在了。
