The invention relates to a sunlight backflow detection device, a head-up display device and a sunlight backflow detection method. In one aspect, a sunlight backward flow detection device is provided, which is arranged on a light emitting side of a display panel of an image generation unit of a head-up display device in use and outside a light envelope of the display panel, the sunlight backward flow detection device comprises: an imaging element for receiving light from the display panel to form an image; the image sensor is arranged on the light emitting side of the imaging element and used for capturing the image; and a monitoring device configured to detect sunlight backflow according to the captured image. Therefore, not only can the accuracy of sunlight backflow detection be improved, but also the internal structure of the head-up display device can be simplified.
本公开涉及阳光倒灌检测装置、抬头显示设备及阳光倒灌检测方法。在一方面中,提供了一种阳光倒灌检测装置,其在使用中布置在抬头显示设备的图像生成单元的显示面板的出光侧,且在显示面板的光包络之外,该阳光倒灌检测装置包括:成像元件,用于接收来自显示面板的光线以形成图像;图像传感器,布置在成像元件的出光侧,以用于捕获该图像;以及监控装置,配置成根据所捕获的图像来检测阳光倒灌。由此,不仅可以提高阳光倒灌检测的准确性,还可以简化抬头显示设备的内部结构。
