Abstract

Disclosed is a display apparatus which considers the speed and traveling mode of a vehicle. The display apparatus includes an information obtaining unit configured to obtain at least one of internal and external information about a vehicle, a control unit configured to process the information obtained by the information obtaining unit into a single image or a plurality of images by using a single image generator and control the image to be changed according to a traveling mode of the vehicle, and a display unit configured to display the image or the plurality of images.

Claims

1. A display apparatus for a vehicle, the display apparatus comprising:

a display comprising a screen;

one or more devices configured to obtain at least one of internal and external information about a vehicle; and

a control unit, comprising at least one processor, configured to;

process the internal and/or external information into a single image or a plurality of images by using an image generator, and control the single image or the plurality of images to be changed according to a traveling mode of the vehicle,

correct distortion of the image according to the traveling mode of the vehicle, or when the traveling mode of the vehicle is the high speed traveling mode, the control unit is configured to control a size of the single image or the plurality of images to be changed to be larger than when the traveling mode of the vehicle is the low speed traveling mode, and

send the single image or the plurality of images to the display;

wherein a resolution of the single image or the plurality of images is higher when the vehicle is a low speed traveling mode than when the vehicle is in a high speed traveling mode,

when the traveling mode of the vehicle is the low speed traveling mode, the plurality of images are sent to the display, with varied projection distances of the plurality of images displayed on the screen of the vehicle for each image, and

when a current vehicle speed is equal to or higher than a predetermined vehicle speed, the control unit is configured to set the traveling mode of the vehicle to the high speed traveling mode, and when the current vehicle speed is lower than a predetermined vehicle speed, the control unit is configured to set the traveling mode of the vehicle to the low speed traveling mode.

2. The display apparatus of claim 1, wherein when the traveling mode of the vehicle is the high speed traveling mode, the control unit is configured to control a number of displayed images to be changed to be smaller than when the traveling mode of the vehicle is the low speed traveling mode.

3. The display apparatus of claim 1, wherein the control unit is configured to control a position of a display area of the single image or the plurality of images to be changed according to the traveling mode of the vehicle.

4. The display apparatus of claim 1, wherein when the traveling mode of the vehicle is the low speed traveling mode, the display varies magnifications of a plurality of images displayed on the screen of the vehicle for each image.

5. The display apparatus of claim 1, wherein the display comprises a head up display (HUD) projecting a virtual image into a visible area of a driver.

6. The display apparatus of claim 5, wherein the HUD comprises a digital light processing (DLP) panel.

7. A display method, comprising:

obtaining internal or external information about a vehicle,

processing the obtained information into a single image or a plurality of images by using an image generator,

correcting distortion of the single image or the plurality of images according to the traveling mode of the vehicle, or when the traveling mode of the vehicle is the high speed traveling mode, changing a size of the single image or the plurality of images to be larger than when the traveling mode of the vehicle is the low speed traveling mode,

changing the single image or the plurality of images according to a traveling mode of the vehicle, and

displaying a changed image according to the traveling mode of the vehicle;

wherein a resolution of the changed image is higher when the travelling mode of the vehicle is a low speed traveling mode than when the travelling mode of the vehicle is a high speed traveling mode,

when the traveling mode of the vehicle is the low speed traveling mode, displaying the plurality of images and varying projection distances of the plurality of images displayed on the screen of the vehicle for each image, and

when a current vehicle speed is equal to or higher than a predetermined vehicle speed, setting the traveling mode of the vehicle to the high speed traveling mode, and when the current vehicle speed is lower than the predetermined vehicle speed, setting the traveling mode of the vehicle to the low speed traveling mode.

8. The display method of claim 7, wherein the processing of the obtained information comprises, when the traveling mode of the vehicle is the high speed traveling mode, changing a number of displayed images to be smaller than when the traveling mode of the vehicle is the low speed traveling mode.

9. The display method of claim 7, wherein the changing of the image comprises changing a position of a display area of the changed image according to the traveling mode of the vehicle.

10. The display method of claim 7, wherein the displaying of the changed image comprises, when the traveling mode of the vehicle is the low speed traveling mode, displaying the plurality of images and varying magnifications of the plurality of images displayed on the screen of the vehicle for each image.

11. The display method of claim 7, wherein a head up display (HUD) projecting a virtual image into a visible area of a driver displays the changed image.

12. The display method of claim 11, wherein a digital light processing (DLP) panel projects the virtual image.
