交叉引用

技术领域
本发明涉及光电技术领域，尤其涉及一种像素单元、光电传感器、摄像模组及电子设备。
背景技术
目前摄像头中光电传感器的感光方式和人眼类似，光电传感器的像素上覆盖的三原色(Red-Green-Blue，RGB)三种颜色滤波阵列(color filer array，CFA)模拟人眼的三种视锥细胞，对光谱反射曲线进行采样，形成数字信号后通过图像信号处理(Image Signal Processing，ISP)的处理，最终成为图像。
上述光电传感器的感光方式与人眼感光方式的区别是：光电传感器中每个像素只能获取RGB中的一种，而人眼的视锥细胞分布非常密集，可以等效理解为每个像素同时获取到RGB三个信号。采用上述光电传感器可能会导致其生成的图像相对于人眼感知到的图像的细节处出现伪色，即在图像中会产生严重的人工痕迹如彩色镶边等虚假颜色效应。
