In-vehicle information display apparatus and method of controlling the same

1. A method of controlling an in-vehicle information display apparatus, the method comprising:

upon detecting that an event occurs, determining an image corresponding to the event and an output region, by a controller, among a plurality of regions of a windshield;

correcting, by the controller, the determined image to match the determined output region; and

projecting the corrected image onto the determined output region through a projection unit disposed on a rear surface opposite to a front surface on which a display of a protrusion type information display apparatus is disposed.

2. The method of claim 1 , wherein the projector unit includes:

at least one image projection device; and

a projector driver configured to rotate at least some of the at least one image projection device along at least one axis.

3. The method of claim 2 , wherein projecting the corrected image includes controlling the projector driver to rotate an image projection device corresponding to the determined output region toward the determined output region among the at least one image projection device.

4. The method of claim 2 , wherein correcting the determined image is performed in consideration of at least one of curves of the output region of the windshield, or an angle or a distance between the output region and the image projection device.

5. The method of claim 2 , wherein correcting the determined image is performed with reference to a table provided with respect to a plurality of preset output regions.

6. The method of claim 2 , wherein the at least one image projection device includes a plurality of image projection devices; and

wherein the projector driver is disposed in each of the plurality of image projection devices.

7. The method of claim 6 , wherein horizontal angles at which the image projection devices are respectively directed are different from each other; and

wherein the projector driver independently rotates the plurality of image projection devices in at least a vertical direction.

8. A non-transitory computer readable recording medium containing program instructions executed by a processor, the computer readable medium comprising:

program instructions that, upon detecting that an event occurs, determine an image corresponding to the event and an output region, among a plurality of regions of a windshield;

program instructions that correct the determined image to match the determined output region; and

program instructions that project the corrected image onto the determined output region through a projection unit disposed on a rear surface opposite to a front surface on which a display of a protrusion type information display apparatus is disposed.

9. A protrusion type information display apparatus applied to a vehicle, comprising:

an output region determination unit configured to, upon detecting that an event occurs, determine an image corresponding to the event and an output region, among a plurality of regions of a windshield;

a screen correction unit configured to correct the determined image to match the determined output region; and

a projector unit disposed on a rear surface opposite to a front surface on which a display is disposed and configured to project the corrected image onto the determined output region.

10. The apparatus of claim 9 , wherein the projector unit includes:

at least one image projection device; and

a projector driver configured to rotate at least some of the at least one image projection device along at least one axis.

11. The apparatus of claim 10 , wherein the projector driver rotates an image projection device corresponding to the determined output region toward the determined output region among the at least one image projection device.

12. The apparatus of claim 10 , wherein the screen correction unit performs correction in consideration of at least one of curves of the output region of the windshield, or an angle or a distance between the output region and the image projection device.

13. The apparatus of claim 10 , wherein the screen correction unit performs correction with reference to a table provided with respect to a plurality of preset output regions.

14. The apparatus of claim 13 , wherein horizontal angles at which the image projection devices are respectively directed are different from each other; and

wherein the projector driver independently rotates the plurality of image projection devices in at least a vertical direction.

15. The apparatus of claim 10 , wherein the at least one image projection device includes a plurality of image projection devices; and

wherein the projector driver is disposed in each of the plurality of image projection devices.
