Camera arrangement
First Claim
1. A camera arrangement to be mounted to a vehicle to detect a human, the arrangement comprising, a camera to capture a light image, the camera providing an output signal and a processor, wherein the arrangement is adapted to have a first mode of operation when surrounding brightness of the vehicle is above a first predetermined threshold and a second mode of operation when the surrounding brightness of the vehicle is below a second predetermined threshold;
- the processor being operable in the first mode of operation only when ambient light in the field of view of the camera is above the first predetermined threshold, to analyse the output signal to identify any area or areas of the light image which have a specific spectral content representative of human skin, and to determine the position of any so identified area or areas within the light image.

Abstract
A camera arrangement is mounted on a motor vehicle to detect a human within or outside the vehicle. The output from the camera is processed by a processor to identify any area or areas of the captured image which have a specific spectral content representative of human skin. A processor may determine the position of any identified area within the image and may control or modify the actuation of one or more safety devices. The arrangement may be used in a motor vehicle, and the processor may control or modify the deployment of a safety device, such as an air-bag, depending upon the position of a seat occupant or a safety device for a pedestrain.
