The invention provides an anti-shake light path, an anti-shake method and an anti-shake detection method for a head-up display. The anti-shake light path of the head-up display comprises a first image source, an image adjusting assembly and an image receiving device, wherein the first image source emits first image light; the image adjusting assembly turns the first image light to form a first target virtual image; the image receiving device is arranged outside the light envelope range of the first image light and is fixed relative to the first image source; test light is arranged in the head-up display, the image receiving device receives the test light reflected by the image adjusting assembly, and the head-up display obtains the jitter amount of the image adjusting assembly according to the test light received by the image receiving device and determines the picture offset compensation amount according to the jitter amount. The first image source adjusts the first image light according to the frame offset compensation amount. The anti-shake light path of the head-up display can monitor the shake condition of the head-up display and adjust the image source according to the shake condition to carry out image compensation, so that the stability of a display picture of the head-up display is improved.
本公开提供一种抬头显示器防抖光路、抗抖动方法和抗抖动检测方法。抬头显示器防抖光路包括第一像源、图像调节组件与图像接收装置,第一像源出射第一图像光线;图像调节组件转折第一图像光线以形成第一目标虚像;图像接收装置设于第一图像光线的光包络范围之外且与第一像源相对固定;抬头显示器内具有测试光线,图像接收装置接收经图像调节组件反射的测试光线,抬头显示器根据图像接收装置接收的测试光线获取图像调节组件的抖动量并根据抖动量确定画面偏移补偿量,第一像源根据画面偏移补偿量调节第一图像光线。本公开的抬头显示器防抖光路能够监测抬头显示器的抖动情况,并根据抖动情况调节像源以进行图像补偿,提高抬头显示器显示画面的稳定性。
