Abstract

A method displays information graphically on an image captured by a vehicular optical system. The method includes capturing the image and identifying an object in the image. The method the assigns a priority level to the object based on a predetermined criterion. The object is altered based on its priority level to create an altered object. An altered object may have a changed color, a colored halo surrounding it, or a colored object inside it. Other possible ways to alter the way the object looks are possible. The altered object is displayed in the image in place of the object on a mobile device to alert a person of its presence and the priority level associated therewith.

First claim

We claim:

1. A method for displaying information graphically on an image captured by an optical system used to simulate a mirror system, the method comprising the steps of:
capturing the image;
identifying an object in the image;
defining an outer periphery of the object;
assigning a priority level to the object based on a predetermined criterion;
altering the object based on its priority level to create an altered object by creating a halo disposed outside and adjacent the outer periphery such that the halo has a shape similar to the outer periphery of the object;
transmitting the image with the altered object to a mobile device; and
displaying the altered object in the image in place of the object on a mobile device to be viewed by a person to alert the person of its presence and the priority level associated therewith.

2. A method as set forth in claim 1 including the step of changing the priority level as conditions between the object and the vehicle change.

3. A method as set forth in claim 2 including the step of updating the halo around the object due to changes in the priority level.

4. A method as set forth in claim 3 wherein the step of updating the halo includes changing one or more characteristic parameter of the halo, each characteristic parameter being selected from a group including color, brightness, thickness, transparency, contrast and position of the halo.

5. A method as set forth in claim 3 wherein the step of updating the halo includes periodically switching the halo on and off to represent a pulsating halo.

6. A method as set forth in claim 1 including the step of reverting the altered object back to the object when the priority level of the object is reduced below a predetermined level.

7. A method as set forth in claim 1 wherein the step of identifying the object in the image includes the step of characterizing the object as animate or inanimate prior to the step of creating the altered object.

8. A method as set forth in claim 1 wherein the step of identifying the object in the image includes the step of characterizing the object as another road user prior to the step of creating the altered object.

9. A method as set forth in claim 8 wherein the other road user is selected from a group comprising a motor vehicle, a bicycle, a pedestrian and an animal prior to the step of creating the altered object.

10. A method as set forth in claim 8 wherein the other road user is selected from a group comprising a car, a bus, a truck, a caravan, a police car, an ambulance vehicle prior to the step of creating the altered object.

11. A method as set forth in claim 7 or 8 , wherein the object is altered to create the altered object based upon the characterization of the object.

12. A method as set forth in claim 1 wherein the step of altering the object to create the altered object includes the step of coloring at least a portion of the object.

13. A method as set forth in claim 12 wherein the step of coloring at least a portion of the object includes the step of coloring a geometric shape within the object.

14. A method as set forth in claim 1 wherein the step of assigning a priority level to the object based on a predetermined criterion includes the step of assigning one of a plurality of priority levels to the object based on a set of predetermined criteria.

15. A method as set forth in claim 14 wherein each of the plurality of priority levels relates to a separate degree of alert.

16. A method as set forth in claim 15 including the step of changing the altered object based on a set of external conditions wherein the set of external conditions are selected from a group consisting of ambient light, types of ambient light, temperature, precipitation and road conditions.

17. A method as set forth in claim 15 wherein the set of predetermined criteria are selected from a group consisting of relative distance, relative velocity, and relative acceleration between the vehicle and the object.
