An image analysis device installed on a vehicle for detecting objects that are likely to affect the vehicle. An image processing unit included in the image analysis device sets a seeking area in a left-hand image of the field, and calculates a moving increment for seeking 'Step' using a variable 'n'. A correlation calculation process is sequentially executed in the seeking area set in the left-hand image of the field while moving a reference image stepwise at the moving increment &#x201c;Step&#x201d; so as to obtain a correlation area that gives the highest degree of correlation, and then a new seeking area is set, which consists of the correlation area and horizontally arranged two areas that sandwich the correlation area, and the moving increment &#x201c;Step&#x201d; is decreased in order to reduce the amount of calculation.
