Abstract
An in-vehicle display apparatus in a vehicle includes a region recognition circuit and an image output circuit. The region recognition circuit recognizes a target plane region in scenery ahead of the vehicle; the target plane region corresponds to a continuous region having (i) a flatness equal to or greater than a predetermined threshold value and (ii) an area size equal to or greater than a predetermined threshold value. The image output circuit displays a driving information picture as a virtual image using a liquid crystal panel such that a driver of the vehicle views the virtual image in the target plane region within a displayable region through a windshield of the vehicle.
Claims12
An in-vehicle display apparatus in a vehicle, comprising:
- a virtual image display device to permit a windshield or a combiner to reflect a predetermined light towards an eye of a driver of the vehicle to display a picture, the virtual image display device displaying the picture in a displayable region as a virtual image appearing ahead of the vehicle;
- a region recognition circuit to recognize a target plane region in scenery ahead of the vehicle, the target plane region being a continuous region having (i) a flatness equal to or greater than a predetermined threshold flatness and (ii) an area size equal to or greater than a predetermined threshold area size;
- and
- an image output circuit to cause the virtual image display device to display the virtual image in the displayable region such that a driver of the vehicle views the virtual image in the target plane region recognized by the region recognition circuit.
An in-vehicle display apparatus in a vehicle, comprising:
- a virtual image display device to permit a windshield or a combiner to reflect a predetermined light towards an eye of a driver of the vehicle to display a picture, the virtual image display device displaying the picture in a displayable region as a virtual image appearing ahead of the vehicle;
- a region recognition circuit to recognize a target space region in scenery ahead of the vehicle, the target space region being a continuous region having (i) a distance equal to or greater than a predetermined threshold distance from the vehicle and (ii) an area size equal to or greater than a predetermined threshold area size;
- and
- an image output circuit to cause the virtual image display device to display the virtual image in the displayable region such that a driver of the vehicle views the virtual image in the target space region recognized by the region recognition circuit.
An in-vehicle display apparatus in a vehicle, comprising:
- a virtual image display device to permit a windshield or a combiner to reflect a predetermined light towards an eye of a driver of the vehicle to display a picture, the virtual image display device displaying the picture in a displayable region as a virtual image appearing ahead of the vehicle;
- an image output circuit to cause the virtual image display device to display the virtual image in the displayable region such that a driver of the vehicle views the virtual image in a predetermined target region;
- and
- a region recognition circuit to recognize a monotonous region, which is a continuous region having an identical color tone, within the target region,
- wherein the image output circuit causes the virtual image display device to switch the virtual image into a non-displayed state when a ratio of the monotonous region to the target region is equal to or less than a predetermined threshold ratio.
An in-vehicle display apparatus in a vehicle, comprising:
- a virtual image display device to permit a windshield or a combiner to reflect a predetermined light towards an eye of a driver of the vehicle to display a picture, the virtual image display device displaying the picture in a displayable region as a virtual image appearing ahead of the vehicle;
- an image output circuit to cause the virtual image display device to display the virtual image in the displayable region such that a driver of the vehicle views the virtual image in a predetermined target region;
- and
- a region recognition circuit to recognize a necessary information region, which provides information needed to drive the vehicle, within the target region,
- wherein the image output circuit causes the virtual image display device to switch the virtual image into a non-displayed state when a ratio of the necessary information region to the target region is greater than a predetermined threshold ratio.
