Anti-dazzling rearview mirror

Abstract

The invention relates to the field of safe automobile driving, in particular to an anti-dazzling rearview mirror. The anti-dazzling rearview mirror comprises an optical sensor for detecting a dazzling light source projected to the rearview mirror and saving an image projected to the rearview mirror at the present, and an image processing unit which is used for receiving the image saved by the optical sensor, reducing the brightness of the dazzling light source in the image, and transmitting the processed image to the rearview mirror. The anti-dazzling rearview mirror disclosed by the invention can reduce the brightness of the dazzling light source projected into the image in the rearview mirror through the image processing unit, thus relieving or eliminating halation or dazzling of a driver.

Description

technical field [0001] The invention relates to the field of safe driving of automobiles, in particular to an anti-glare rearview mirror. Background technique [0002] Motor vehicles are usually illuminated with headlights or headlights in the following two situations. One situation is to illuminate the road ahead for vehicles in the case of poor visibility in the surrounding environment, especially in the dark; the other situation It is to alert vehicles on other lanes so that other drivers can see the motor vehicle. The headlights should be based on the premise of not making the driver or other pedestrians feel dizzy during use. However, sometimes the headlights can be very dazzling to oncoming motor vehicle drivers, such as when a truck has not adjusted the headlight illumination (such as not switching from high beam to low beam in time, Especially when turning right), the light of the high beam is caused by astigmatism caused by rain, snow or nebula, etc. The short-ter...

Problems solved by technology

However, sometimes the headlights will be very dazzling to oncoming motor vehicle drivers, such as a truck when the headlight illumination is not adjusted well (such as not switching from high beam to low beam in time, Especially when turning right), the light of the high beam is caused by astigmatism caused by rain, snow or nebula, etc. The short-term glare caused by this kind of headlight is more likely to cause a car accident, because the glare makes it difficult for the driver to notice other lanes Vehicles on the road, especially the elderly are more prone to dazzle or glare, and it takes longer for the elderly to recover to normal vision after feeling the glare
