Abstract: The present disclosure provides an onboard screen casting system, an onboard screen casting method, and a computer-readable storage medium. The onboard screen casting system includes a host system and a virtual machine system; wherein, the virtual machine system is able to receive external bit stream data to be cast and transmit it to the host system; and the host system is able to decode the bit stream data into video stream data, and perform a visibility setting on the video stream data, to display the corresponding video.

Abstract: The present disclosure provides a communicating method for vehicle users, a communicating system for vehicle users, and a computer-readable storage medium. The communicating method includes following steps: establishing a communicating area with respect to the vehicle, and defining a coordinate range of the communicating area; connecting at least one user terminal, and acquiring a personal coordinate from each of the user terminals; and responding to the personal coordinates of user terminals being located in the coordinate range of the communicating area at the same time, to establish information correlation for each user terminal located in the communicating area.

Abstract: The present disclosure provides a processing method, a device and a storage medium for rear view image. The processing method includes following steps: obtaining an original rear view image; obtaining vehicle data to determine at least one basic curvature; obtaining driver information to determine at least one floating curvature; and processing the rear view image according to the at least one basic curvature and the at least one floating curvature. By performing these steps, the processing method can adjust display curvature of the rear view image according to specific driving scenario and user needs, thereby clearly and personalized displaying rear view image with suitable range and display scale on the display screen with limited area, to help the user clearly observe situations on the left, right and rear sides of the vehicle.

Abstract: The present disclosure provides a lens, a photographing device, as well as a processing method, a device and a storage medium for lens humidity. The lens includes a lens body and a humidity sensitive color changing film. The humidity sensitive color changing film is attached to a detection area of a photographing surface of the lens body, and changes color when its humidity is greater than a humidity threshold, to change color of image corresponding to the detection area in a photographed image. By configuring the humidity sensitive color changing film, the present disclosure can efficiently and accurately detect the presence of interference factors, such as water and frost, on surface of the lens at a low cost, thereby facilitating the start and stop control of dewatering/defrosting function, and preventing these external interference factors from adversely affecting the clarity and accuracy of images photographed by an in-vehicle camera.

Abstract: A brightness control method of an illumination device includes: obtaining a brightness of ambient light, determining an amount of supplementary light according to the brightness of the ambient light and target brightness if the brightness of the ambient light is less than the target brightness, and generating a first pulse signal according to the amount of supplementary light to control the illumination device to emit light.

Abstract: An image stitching method includes: receiving a first image and a second image; determining that both the first image and the second image include a target object; obtaining a first brightness value and a second brightness value, the first brightness value being a brightness value of the target object in the first image, and the second brightness value being a brightness value of the target object in the second image; adjusting a brightness value of the first image and a brightness value of the second image according to the first brightness value and the second brightness value, so as to obtain a first image to be stitched and a second image to be stitched; and stitching the first image to be stitched and the second image to be stitched to obtain a first stitched image.

Abstract: An in-vehicle electronic device includes a host, a first camera, and a first driving device. The first camera is moveably connected to the host, and is configured to capture at least one image of an interior of a vehicle. The first driving device is connected to the first camera, and is configured to drive the first camera to slide between an extended position and a retracted position, so that when the first camera is at the extended position, the first camera is located outside the host, and when the first camera is at the retracted position, the first camera is located inside the host.

Abstract: A content display method includes: obtaining target information; determining a target tag according to a first database at a current moment and the target information; obtaining top M pieces of content in the target tag; and displaying the content. The target information includes vehicle state information at the current moment and first information used to characterize a facial expression of a driver in a vehicle at the current moment; and the first database includes a plurality of pieces of historical information corresponding to the driver in a historical period.
