    • Taught herein is an integragted narrow bandpass filter array and a method of its fabrication. The filter array is a Fabry-Perot type of filter array, wherein the pass band changes with the thickness of the spacer layer. The integrated filter array comprises a substrate, a lower mirror stack, a spacer array, and an upper mirror stack. The spacer array is an array of varied thicknesses formed using a combinatorial deposition technique. The spacer array is used to control the pass band of each mini-size narrow bandpass filter and realizes the integration of narrow bandpass filters with different pass bands on a single substrate. The merit of this technique lies in its fabrication efficiency and finished product rate which are much higher than for conventional methods. The filter array is completely matched with detector arrays and functional in most of the important optical ranges.
    • 这里介绍的是一个集成窄带通滤波器阵列及其制造方法。 滤波器阵列是法布里 - 珀罗型的滤波器阵列,其中通带随间隔层的厚度而变化。 集成滤波器阵列包括衬底,下反射镜叠层,间隔物阵列和上反射镜叠层。 间隔物阵列是使用组合沉积技术形成的各种厚度的阵列。 间隔阵列用于控制每个小尺寸窄带通滤波器的通带,实现了单个衬底上具有不同通带的窄带通滤波器的集成。 这种技术的优点在于其制造效率和成品率都远高于传统方法。 滤波器阵列与检测器阵列完全匹配,并且在大多数重要的光学范围中起作用。

    • De-ringing operation for image processing. A selective image processing means is presented herein by which high frequency content is preserved while also eliminating ringing within digital images, and this is achieved without introducing aliasing. Based on the analysis of neighboring pixels, one or more of multiple filter modules and/or multiple image filtering/processing means is/are selectively applied to generate an output sample for a given pixel location. Two measures (e.g., local activity (LA) and edge strength (ES)) are calculated based on processing at least two different groups of pixels near a desired output sample. One of these groups of pixels may be a subset of another of the groups of pixels. By analyzing these two measures (e.g., LA and ES), selective processing of pixels near the desired output location ensures that high frequency content within the digital image is preserved with substantially reduced and/or eliminated ringing therein.
    • 去抖动操作进行图像处理。 本文提出了选择性图像处理装置,通过该选择图像处理装置保持高频内容,同时还消除数字图像内的振铃,并且在不引入混叠的情况下实现。 基于相邻像素的分析,选择性地应用多个滤波器模块和/或多个图像滤波/处理装置中的一个或多个以产生用于给定像素位置的输出样本。 基于在期望的输出样本附近处理至少两个不同的像素组来计算两个度量(例如,局部活动(LA)和边缘强度(ES))。 这些像素组之一可以是像素组中另一组的子集。 通过分析这两个测量(例如LA和ES),对期望输出位置附近的像素的选择性处理确保数字图像内的高频内容被保留,其中基本上减少和/或消除振铃。
