Abstract

An image display method and an image display system are provided. The image display system is deployed in a vehicle. An external image outside the vehicle is captured through a first image capturing unit, and a specific range image is selected in the external image according to an adjusting signal. The specific range image is displayed in a display unit disposed on a pillar inside the vehicle.

Claims

1. An image display method, for an image display system, wherein the image display system is deployed in a vehicle, the image display method comprising:

capturing an external image outside the vehicle through a first image capturing unit;

selecting a specific range image in the external image according to an adjusting signal; and

displaying the specific range image in a display unit, wherein the display unit is disposed on a pillar in the vehicle.

2. The image display method according to claim 1 further comprising:

capturing a driver image through a second image capturing unit; and

analyzing the driver image to generate the adjusting signal.

3. The image display method according to claim 2, wherein the step of analyzing the driver image to generate the adjusting signal comprises:

identifying a specific position in the driver image; and

obtaining a relative position information with respect to the pillar according to the specific position to generate the adjusting signal.

4. The image display method according to claim 3, wherein the step of analyzing the driver image further comprises:

analyzing at least one of a gazing direction of an eyeball and a height of the eyeball to a datum plane in the driver image.

5. The image display method according to claim 2, wherein the first image capturing unit is disposed outside the vehicle, and the second image capturing unit is disposed inside the vehicle.

6. The image display method according to claim 1, wherein a display range of the external image captured by the first image capturing unit is larger than a display range of the display unit.

7. An image display system, adapted to a vehicle, the image display system comprising:

a first image capturing unit, capturing an external image outside the vehicle;

a display unit, disposed on a pillar in the vehicle; and

an image processing unit, coupled to the first image capturing unit and the display unit, receiving the external image from the first image capturing unit, selecting a specific range image in the external image according to an adjusting signal, and displaying the specific range image in the display unit.

8. The image display system according to claim 7 further comprising:

a second image capturing unit, coupled to the image processing unit, wherein the second image capturing unit captures a driver image, and the image processing unit analyzes the driver image to generate the adjusting signal.

9. The image display system according to claim 8, wherein

the image processing unit identifies a specific position in the driver image and obtains a relative position information with respect to the pillar according to the specific position to generate the adjusting signal.

10. The image display system according to claim 9, wherein the image processing unit analyzes at least one of a gazing direction of an eyeball and a height of the eyeball to a datum plane in the driver image.

11. The image display system according to claim 7, wherein a display range of the external image captured by the first image capturing unit is larger than a display range of the display unit.

12. The image display system according to claim 7, wherein the vehicle has a window, the pillar disposed at one side of the window, a window image is obtained through the window by a driver, and the specific range image and the window image are connected into a continuous image.

13. The image display system according to claim 7, wherein the specific range image is a visual field of the driver blocked by the pillar.
