Camera system for a vehicle and method for controlling a camera system
First Claim
1. In combination with a vehicle, a camera system comprising:
- a camera unit mounted on the vehicle for viewing an area outside the vehicle;
an image processing unit operatively connected to said camera unit for receiving image data from said camera unit;
a display unit operatively connected to said image processing unit;
a control unit operatively connected to said display unit, said control unit receiving vehicle operation data including vehicle speed data;
said display unit displaying a screen image generated from the image data provided by said camera unit, said display unit transitioning between a screen image defined by a first viewing angle and a screen image defined by a second viewing angle, the first viewing angle and the second viewing angle extending substantially in a vertical plane, and the first viewing angle being greater than the second viewing angle;
said display unit further displaying, concurrently with the screen image generated from the image data, supplemental information based on the vehicle operation data, the supplemental information including vehicle speed information indicative of a vehicle speed of the vehicle and information indicating a transition behavior of said display unit transitioning between a screen image defined by the first viewing angle and a screen image defined by the second viewing angle, wherein said display unit performs a smooth transition between a screen image defined by the first viewing angle and a screen image defined by the second viewing angle with a transition duration between 0.5 seconds and 2 seconds; and
said control unit controlling said display unit as a function of the vehicle speed data such that said display unit transitions from a screen image defined by the first viewing angle to a screen image defined by the second viewing angle when the vehicle speed falls below a threshold value, wherein said control unit controls said display unit as a function of the vehicle speed data such that said display unit transitions from a screen image defined by the second viewing angle to a screen image defined by the first viewing angle when the vehicle speed rises above a threshold value.

Abstract
A camera system for a vehicle includes a camera unit mounted on the vehicle for viewing an area outside the vehicle. A image processing unit receives image data from the camera unit. A control unit receives vehicle operation data including vehicle speed data. A display unit is configured to transition between a screen image defined by a first viewing angle and a screen image defined by a second viewing angle. The first viewing angle and the second viewing angle extend substantially in a vertical plane, and the first viewing angle is greater than the second viewing angle. The display unit further displays supplemental information based on the vehicle operation data, the supplemental information includes vehicle speed information and information indicating a transition behavior of the display unit configured to transition between the first viewing angle and the second viewing angle. A method for controlling a camera system is also provided.

9. A method for controlling a camera system, the method which comprises:
-
using a camera unit mounted on a vehicle and pointed at an area outside the vehicle for capturing image data; displaying, with a display unit, a screen image generated from the image data provided by the camera unit such that the display unit selectively provides a screen image defined by a first viewing angle and a screen image defined by a second viewing angle, the first viewing angle and the second viewing angle extending substantially in a vertical plane, and the first viewing angle being greater than the second viewing angle; displaying, concurrently with the screen image generated from the image data, supplemental information including at least one of vehicle speed information indicative of a vehicle speed of the vehicle and information indicating a transition behavior of the display unit, which selectively provides a screen image defined by the first viewing angle and a screen image defined by the second viewing angle; and
performing a smooth transition between a screen image defined by the first viewing angle and a screen image defined by the second viewing angle with a transition duration between 0.5 seconds and 2 seconds, wherein the display unit transitions from a screen image defined by the first viewing angle to a screen image defined by the second viewing angle when the vehicle speed falls below a threshold value and transitions from a screen image defined by the second viewing angle to a screen image defined by the first viewing angle when the vehicle speed rises above a threshold value. - View Dependent Claims (10, 11, 12, 13, 14)
