高动态范围彩色图像传感器及相关的方法
Abstract:
高动态范围彩色图像传感器包括(a)具有感光像素阵列的硅基板，感光像素阵列具有多个第一像素和多个第二像素，(b)滤色镜层，滤色镜层被布置在硅基板上并至少包括(i)位于多个第一像素的第一子集和多个第二像素的第一子集的上方并用于选择性透射第一颜色的光的多个第一滤色镜，和(ii)位于多个第一像素的第二子集和多个第二像素的第二子集的上方并用于选择性透射第二颜色的光的多个第二滤色镜，以及(c)动态范围扩展层，动态范围扩展层被布置在滤色镜层上并包括被布置在多个第二像素上方以衰减朝多个第二像素传播的光的灰色滤光镜。
Abstract(English):

A high-dynamic-range color image sensor includes (a) a silicon substrate having a photosensitive pixel array with a plurality of first pixels and a plurality of second pixels, (b) a color filter layerdisposed on the silicon substrate and including at least (i) a plurality of first color filters positioned above a first subset of each of the plurality of first pixels and the plurality of second pixels and configured to selectively transmit light of a first color and (ii) a plurality of second color filters positioned above a second subset of each of the plurality of first pixels and the plurality of second pixels and configured to selectively transmit light of a second color, and (c) a dynamic-range extending layer disposed on the color filter layer and including grey filters disposed above the second plurality of pixels to attenuate light propagating toward the second plurality of pixels.
