    • A system and method for generating multiple images with rich color acquisition using a plenoptic camera having a main lens disposed in front of a micro array of lenses, a mosaic color filter array and an image sensor, characterized in that it comprises: capturing a first set of images using an ordinary state of an electrically controllable birefringent medium being disposed between said main lens and said micro array of lenses, said ordinary state providing an ordinary ray to each pixel; capturing a second set of images using an extraordinary state of said electrically controllable birefringent medium, said extraordinary state splitting the light from said main lens into an ordinary ray and a extraordinary ray respectively impinging on two adjacent pixels of different colors, said extraordinary ray being shifted by distance of one pixel on said image sensor; performing a weighted subtraction of information about said second set of images from information about said first set of images; and generating a final set of images with rich color information from said weighted subtraction and said first set of images.
    • 一种用于使用具有布置在微型透镜阵列前方的主透镜,马赛克滤色器阵列和图像传感器的全光照相机来生成具有丰富色彩采集的多个图像的系统和方法,其特征在于, 该方法包括:使用布置在所述主透镜和所述微透镜阵列之间的电可控双折射介质的普通状态捕获第一组图像,所述常规状态向每个像素提供寻常光线; 使用所述电可控双折射介质的非常态来捕获第二组图像,所述非常态将来自所述主透镜的光分成普通光线和非常光线,分别照射在不同颜色的两个相邻像素上,所述非常光线被移动 通过所述图像传感器上的一个像素的距离; 从关于所述第一组图像的信息中执行关于所述第二组图像的信息的加权减法; 并从所述加权减法和所述第一组图像中生成具有丰富色彩信息的最终图像集。
