PROBLEM TO BE SOLVED: To accurately detect a line-of-vision by highly accurately compositing eye images at high speed on the basis of a plurality of eye images. SOLUTION: This detector has an optical image forming system for forming a plurality of eye images of the eyes of an observer through an optical finder system, a plurality of light sources for forming Purkinje images and arithmetic means (#301-#317) for extracting the Purkinje images contained in each of a plurality of eye images, compositing a plurality of eye images on the basis of a plurality of Purkinje images and calculating the attention point of the observer from the composite eye image, and the images of coordinates almost equal in the direction orthogonal with the arranging direction of the light sources are extracted from a plurality of eye images as a plurality of Purkinje images. |
