BUNDLING OF DRIVER ASSISTANCE SYSTEMS
First Claim
1. A method for performing at least one driver assistance function, the method using a computerized system mounted on a moving vehicle, the computerized system including a camera and an image processor, wherein under control of the image processor the camera is adapted for capturing in real time a plurality of image frames of the environment in the field of view of the camera, the method comprising:
- partitioning a first portion of the image frames and a second portion of the image frames;
for said first portion of the image frames, controlling a camera parameter based on ambient lighting conditions in the environment in the field of view of the camera;
based on said camera parameter of said first portion of the image frames, setting a camera parameter of said second portion of the image frames;
capturing the image frames; and
transferring the image frames to the processor for processing of the at least one driver assistance function.

Abstract
A traffic sign recognition system including a detection mechanism adapted for detecting a candidate traffic sign and a recognition mechanism adapted for recognizing the candidate traffic sign as being an electronic traffic sign. A partitioning mechanism may be adapted for partitioning the image frames into a first partition and a second partition. The detection mechanism may use the first portion of the image frames and the recognition mechanism may use the second portion of the image frames. When the candidate traffic sign is detected as an electronic traffic sign, the recognition mechanism may use both the first partition of the image frames and the second portion of the image frames.
