Abstract

The present application relates to a head-up display apparatus, a control method thereof, and a vehicle. The head-up display apparatus comprises: an image projecting device, a display background detecting device, and a processor. The image projecting device is configured to generate an image and project the image onto a preset area on a reflective surface. The display background detecting device is configured to detect optical information of a background space that a user can see through the preset area, wherein the background space and the user are located at opposite sides of the reflective surface. The processor is configured to determine an image displaying mode of the image projecting device based on the optical information, and to control the image projecting device to project images in the determined image displaying mode.

Claims

1. A head-up display apparatus, comprising:

an image projecting device configured to generate and project an image to be displayed, wherein the image projecting device projects the image onto a preset area on a reflective surface;

a display background detecting device configured to detect optical information of a background space that a user can see through the preset area, wherein the background space and the user are located at opposite sides of the reflective surface;

a color recognition ability device configured to obtain color recognition ability information of the user; and

a processor configured to determine an image displaying mode of the image projecting device based on the obtained color recognition ability information of the user and the optical information, and to control the image projecting device to project images in the determined image displaying mode,

wherein the color recognition ability device comprises;

a color vision analyzer configured to perform a color recognition ability test on the user to obtain a color vision analysis result for the user,

wherein the color recognition ability device is further configured to;

obtain the color vision analysis results by the color vision analyzer, and

utilize the color vision analysis result as the color recognition ability information.

2. The apparatus of claim 1, wherein the optical information comprises at least one of luminance information or color information, and

parameters of the image displaying mode include at least one of image color or image luminance.

3. The apparatus of claim 1, wherein the color recognition ability device further comprises:

a memory configured to store the color vision analysis result for the user in association with the identity information,

wherein the color recognition ability device is further configured to;

obtain the identity information of the user by the identity identifying device,

obtain the color vision analysis result for the user from the memory based on the identity information; and

utilize the color vision analysis result as the color recognition ability information.

4. The apparatus of claim 3, wherein the identity identifying device is further configured to:

collect biometric information of the user, the biometric information including at least one of face information, fingerprint information, or iris information; and

identify the identity information of the user based on the biometric information.

5. The apparatus of claim 1, wherein the display background detecting device is implemented as one or more of a camera, a photosensor, and other electronic device having an image information collecting function.

6. The apparatus of claim 1 wherein the processor is further configured to:

provide a plurality of candidate image displaying modes based on the optical information;

apply the image displaying mode selected by the user from the plurality of candidate image displaying modes to the image projecting device.

12. A vehicle comprising a head-up display apparatus of claim 1.

13. The vehicle of claim 12, wherein the optical information comprises at least one of luminance information or color information, and

parameters of the image displaying mode include at least one of image color or image luminance.

14. The vehicle of claim 12, wherein the color recognition ability device further comprises:

wherein the color recognition ability device is further configured to;

obtain the identity information of the user by the identity identifying device,

obtain the color vision analysis result for the user from the memory based on the identity information; and

utilize the color vision analysis result as the color recognition ability information.

7. A method of controlling a head-up display apparatus comprising an image projecting device configured to generate and project an image to be displayed, wherein the image projecting device projects the image onto a preset area on a reflective surface, the method comprising:

detecting optical information of a background space that a user can see through the preset area, wherein the background space and the user are located at opposite sides of the reflective surface;

obtaining color recognition ability information of the user;

determining an image displaying mode of the image projecting device based on the obtained color recognition ability information of the user and the optical information; and

controlling the image projecting device to project images in the determined image displaying mode,

wherein the step of obtaining the color recognition ability information of the user further comprises;
