A virtual visor system is disclosed that includes a visor having a plurality of independently operable pixels that selectively operate with a variable opacity. The camera captures a face image of the driver or other passenger, and based on the captured image, the controller operates the visor to automatically and selectively darken a limited portion thereof to block sunlight or other illumination sources from impacting the driver's eyes while leaving the remainder of the visor transparent. The virtual visor system advantageously employs a graded blocking mode for the optical state of the visor, the graded blocking mode including a blocking portion and a transition gradient, which has the effect of less distracting the update of the optical state of the visor. In addition, the transition gradient of the optical state of the visor makes the virtual visor system more robust to errors that position the barrier on the visor.

    公开了一种虚拟遮阳板系统,其包括具有多个独立可操作的像素的遮阳板,所述像素以可变的不透明度选择性地操作。相机捕获驾驶员或其他乘客的脸部图像,并且基于所捕获的图像,控制器操作遮阳板以自动和选择性地使其有限部分变暗,从而阻挡阳光或其他照明源冲击驾驶员的眼睛,同时使遮阳板的其余部分保持透明。虚拟遮阳板系统有利地对遮阳板的光学状态采用渐变阻挡模式,所述渐变阻挡模式包括阻挡部和过渡渐变,其具有使对遮阳板的光学状态的更新更少分散注意力的效果。此外,遮阳板的光学状态的过渡渐变使得虚拟遮阳板系统对于将阻挡部定位在遮阳板上的错误更加鲁棒。
