OPTICAL DEVICE PROVIDED WITH DEVICE FOR DETECTING LINE OF SIGHT

摘要

PURPOSE:To obtain an optical device provided with a device for detecting the line of sight in which the detecting accuracy in detecting the line of sight is enhanced by automatically correcting the detection error of the line of sight caused by the individual difference of the size of the eyeball by using a means for correcting the line of sight, which is appropriately set. CONSTITUTION:This device is provided with the means for correcting the line of sight capable of obtaining line of sight correction data for correcting the detection error caused by the individual difference of the eyeball 16 and changing the number of times of detecting the line of sight by allowing the device for detecting the line of sight to detect the line of sight plural times by using a target displayed on the observation surface of a finder system in the case of detecting the rotational angle of the optical axis of the eyeball 15 of an observer looking in the finder system so that the line of sight of the observer is detected by the device for detecting the line of sight based on the rotational angle.
