Screen transmission image processing method, vehicle-mounted equipment, storage medium and vehicle

The invention provides a screen transmission image processing method, vehicle-mounted equipment, a storage medium and a vehicle. The method comprises the following steps: receiving a screen transmission image obtained by performing pixel filling on a receiving end by a screen projection end; determining a second display mode of the screen projection end according to the first display mode of the receiving end and the image bitmap corresponding to the screen transmission image; and determining whether to adjust the image bitmap according to the second display mode and the first display mode. The receiving end judges the second display mode of the screen projection end through the screen transmission image, and further adjusts the image bitmap corresponding to the screen transmission image according to the second display mode and the first display mode of the receiving end, so as to obtain a final display picture, thereby ensuring that the actual screen transmission data in the displayed picture occupies a large proportion, and improving the user experience. And the screen transmission image impression of the user is improved.
