Abstract

A vehicle auxiliary display device, which includes a display unit and a processor. The display unit is configured to display according to instructions from the processor. The processor is configured to acquire the current driving speed of the vehicle and, according to the current driving speed, match a display effect of a partial display area of the display unit to the current driving speed so as to enhance the display effect of the partial display area relative to the remaining display area of the display unit.

First claim

The invention claimed is:

1. A vehicle auxiliary display device, comprising a display unit, an image acquiring unit, and a processor, wherein
the processor is configured to acquire a current driving speed of a vehicle and, according to the current driving speed, match a display effect of a partial display area of the display unit to the current driving speed so as to enhance the display effect of the partial display area relative to a remaining display area of the display unit,
the display unit is configured to display images according to instructions from the processor,
the display unit comprises at least a first area and a second area,
the image acquiring unit is configured to acquire first images and send the first images to the processor, and
the processor is further configured to process a first part of the first images to weaken the display effect of the first area when the current driving speed is lower than a first speed threshold,
wherein the processor is further configured to process a second part of the first images in such a way as to enhance the display effect of the second area when the current driving speed is lower than the first speed threshold; and
wherein the processor is further configured to send the processed first images to the display unit, wherein the processor is further configured to process the second part of the first images in such a way as to weaken the display effect of the second area when the current driving speed is higher than the first speed threshold.

2. The display device of claim 1 , wherein
the first area is used to display images of distant scenes which are located at a distance from the vehicle larger than a first distance threshold; and
the second area is used to display images of near scenes which are located at a distance from the vehicle smaller than the first distance threshold.

3. The display device of claim 1 , wherein the display device further comprises a plurality of light sources,
the plurality of light sources are respectively disposed on at least one side of the first area and at least one side of the second area of the display unit, and
the processor is further configured to turn on the light sources on at least one side of the first area or those on at least one side of the second area to enhance the display effect of the first or second area according to the current driving speed.

4. The display device of claim 1 , wherein
the display unit further comprises a third area located between the first area and the second area and used to display a third part of the first images; and
the processor is further configured to process the first part of the first images displayed in the first area, the second part of the first images displayed in the second area, or the third part of the first images displayed in the third area according to the current driving speed so as to enhance the display effect of the first, second, or third area.

5. The display device of claim 4 , wherein
the first area is used to display images of distant scenes which are located at a distance from the vehicle larger than a first distance threshold;
the second area is used to display images of near scenes which are located at a distance from the vehicle smaller than a second distance threshold, the second distance threshold being smaller than the first distance threshold; and
the third area is used to display images of scenes which are located at a distance from the vehicle ranged between the first distance threshold and the second distance threshold.

6. The display device of claim 5 , wherein the processor is further configured to:
process the first part of the first images to enhance the display effect of the first area when the current driving speed is higher than the first speed threshold;
process the second part of the first images to enhance the display effect of the second area when the current driving speed is lower than a second speed threshold; and
process the third part of the first images to enhance the display effect of the third area when the current driving speed is higher than the second speed threshold and lower than the first speed threshold.

7. The display device of claim 6 , wherein the processor is further configured to enhance the display effect of one of the first, second, and third areas, and meanwhile weaken the display effect of the other two areas.

8. The display device of claim 1 , wherein a plurality of light sources included in the display device are respectively disposed on at least one side of the first area, at least one side of the second area, and at least one side of a third area of the display unit, and
the processor is further configured to turn on the light sources around the first area, the second area, or the third area according to the current driving speed so as to enhance the display effect of the first, second, or third area.

9. A vehicle, comprising the vehicle auxiliary display device of claim 1 .

10. The display device of claim 1 , wherein the processor is further configured to process the first part of the first images in such a way as to enhance the display effect of the first area when the current driving speed is higher than the first speed threshold.

11. A display method for a vehicle auxiliary display device, wherein the vehicle auxiliary display device comprises a display unit, an image acquiring unit, and a processor, the display method comprising:
acquiring, by the processor, a current driving speed of a vehicle and, according to the current driving speed, matching a display effect of a partial display area of the display unit to the current driving speed to make it enhanced relative to a remaining display area of the display unit; and
displaying, by the display unit according to instructions from the processor, images,
wherein the display unit comprises at least a first area and a second area,
the image acquiring unit acquires first images and sends the first images to the processor, and
wherein, when the current driving speed is lower than a first speed threshold, the processor processes a first part of the first images to weaken the display effect of the first area,
wherein the display method further comprises: processing, by the processor, a second part of the first images to enhance the display effect of the second area when the current driving speed is lower than the first speed threshold; and
sending the processed first images to the display unit for display,
wherein the display method further comprises: when the current driving speed is higher than the first speed threshold, processing, by the processor, the second part of the first images to weaken the display effect of the second area.

12. The display method of claim 11 , wherein the first area is used to display images of distant scenes which are located at a distance from the vehicle larger than a first distance threshold; and
the second area is used to display images of near scenes which are located at a distance from the vehicle smaller than the first distance threshold.

13. The display method of claim 11 , wherein the display device further comprises a plurality of light sources, and
the plurality of light sources are disposed respectively on at least one side of the first area and at least one side of the second area of the display unit,
the method further comprising: turning on, by the processor, the light sources on at least one side of the first area or those on at least one side of the second area according to the current driving speed to enhance the display effect of the first area or the second area.
