In-vehicle rear-view display system and display method

An in-vehicle rear-view display system, comprising:

• a display device comprising a dimming device configured to adjust luminance of light emitted from the display device based on a color change of the dimming device;
• a first controller comprising hardware, the first controller being connected with the dimming device and configured to control the color change of the dimming device in accordance with a luminance change of an ambient light;
• a photosensitive sensor arranged on a display side of the display device and configured to measure luminance of the ambient light;
• a luminance calculator connected with the photosensitive sensor and configured to calculate, in response to determining that the luminance of the ambient light measured by the photosensitive sensor has changed, a luminance change amount of the ambient light and a time period Δt during which the luminance change amount of the ambient light is maintained;
• wherein the first controller is configured to control, in accordance with the calculated luminance change amount and a corresponding relationship between luminance change amounts and color modes of the dimming device, the dimming device to be in a corresponding color mode in response to determining that an absolute value of the luminance change amount being greater than a preset luminance threshold and the time period Δt exceeds a preset time period T, and wherein the color modes of the dimming device are divided according to the luminance of light emitted by the dimming device.
