Abstract

Camera adjustment apparatuses are arranged in an area to be recognized by a camera that captures an image of an object to be recognized, and include: an adjustment mark position detection unit to detect adjustment marks for extracting subject information including a size, a direction, and luminance from an image captured by the camera and detect positions of the detected adjustment marks in the captured image; a subject information extraction unit to extract the subject information from the adjustment marks detected by the adjustment mark position detection unit; and a recognition feasibility determination unit to determine whether each of the adjustment marks detected by the adjustment mark position detection unit can be recognized by comparing the corresponding subject information with a predetermined determination criterion, and generate adjustment information for adjusting the camera based on subject information that corresponds to one of the adjustment marks.
