Abstract

A multimedia rear-view mirror system (100) and a method for adjusting the size of a mirror reflection area thereof. A multimedia video module (120) sends a video signal to a display screen driving module (130), a vehicle state sensing module (140) sends a sensed vehicle state to the display screen driving module (130), and the display screen driving module (130) superimposes a black blocking signal on the video signal in response to reception of the video signal when the vehicle state is in a forward driving state, so that a display screen displays the superimposed video signal. Therefore, by using the display screen driving module (130) and the vehicle state sensing module (140), an image displayed on the display screen can be partially blocked when the vehicle is in the forward driving state, to prevent a driver from watching entertainment videos normally, thereby improving driving safety, or the driver can still obtain brief navigation information via a non-blocked part of the display screen on the rear-view mirror when the size of the mirror reflection area is sufficient, thereby improving driving convenience.

Description

technical field [0001] The invention relates to the field of automobile accessories, in particular to a multimedia rearview mirror system and a method for adjusting the size of a reflection area thereof. Background technique [0002] Car rearview mirrors on the market are generally divided into two categories. One type of rearview mirror is integrated with multimedia modules such as WINCE or Android to have functions such as navigation and video playback. The other type is that the rearview mirror is integrated with a display module that can receive video and audio signals from mobile phones or other devices in a wireless or wired manner. The display screen in this type of rearview mirror is directly driven by multimedia modules such as WINCE or Android. [0003] However, for the above two multimedia rearview mirrors, in addition to the navigation map, the openness of multimedia modules such as WINCE or Android allows the driver to freely control mobile phones and other devi...
