Abstract

The invention discloses an on-vehicle head-up terminal and a method for controlling display brightness of the same. The on-vehicle head-up display terminal comprises a controller, a display device which is connected with the controller, and an eyeball tracking device. The eyeball tracking device is connected with the controller and is used for monitoring movement of eyeballs in real time and transmitting captured image information to the controller. The controller is used for determining a visual line focusing point of the eyeballs according to an eyeball tracking algorithm and controlling the operation state of the display device according to determining result. According to the technical solution of the invention, the eyeball movement of a driver is monitored in real time through adding the eyeball tracking device; furthermore whether the visual line focusing point is on the display device is determined; and the operation state of the display device is controlled according to the determining result, thereby ensuring a fact that attention of the driver is not interfered by the display content and brightness, reducing negative effect of the on-vehicle head-up display terminal in a using process and furthermore greatly reducing power consumption of equipment.

Description

technical field [0001] The invention relates to the field of intelligent terminal control, in particular to a vehicle-mounted head-up display terminal and a method for controlling its display brightness. Background technique [0002] The vehicle-mounted head-up display terminal (HeadUpDisplay, HUD) is usually installed in front of the driver, and can provide the driver with some necessary driving information during driving, such as vehicle speed, fuel consumption, navigation, and even mobile phone calls and message reminders. It can be seen that the HUD integrates multiple functions into one, which is convenient for the driver to pay attention to the driving conditions. [0003] However, because the HUD is located in front of the driver's line of sight and is always in the display state, it will also cause a certain degree of visual interference to the driver. For example: when the display content changes, people will unconsciously observe; when driving at night, the HUD Th...
