1. An image processing apparatus comprising:
- an input portion for entering an image signal from a camera that captures images of surroundings of a vehicle;
an exposure timing determination portion which determines an exposure timing of said camera according to at least one of a plurality of objects to be detected, wherein said at least one of said plurality of objects comprises a lane, a headlight or a taillight of another vehicle, or a brightness of said surroundings;
an output portion which outputs a signal to said camera to expose said camera according to said exposure timing determined by said exposure timing determination portion and outputs a signal to an illumination controller to vary a state of an illumination system installed on said vehicle according to said exposure timing; and
an image analysis portion which analyzes an image signal derived from said camera according to said exposure timing and outputs analysis results to another controller via said output portion.

8. An image processing method comprising the steps of:
-
determining an exposure timing of a camera that acquires images of surroundings of a vehicle, wherein the exposure timing is determined according to at least one of a plurality of objects to be detected, and said at least one of said plurality of objects comprises a lane, a headlight or a taillight of another vehicle, or a brightness of said surroundings; outputting a signal to said camera to expose said camera according to said exposure timing; outputting a signal to an illumination controller to vary a state of an illumination system installed on said vehicle according to said exposure timing; analyzing an image signal acquired by said camera according to said exposure timing; and outputting analysis results to another controller via said output portion.
