摘要 |
View point detecting apparatus wherein first and subsequent view point data are compared includes state detecting structure for detecting the state of an observer's view point. Circuitry is provided for determining, when amounts of a variation between a first view point information and a subsequent view point information exceed a predetermined value, that the first view point information is effective. Preferably, structure is also provided for adjusting a photo-taking lens on the basis of the first view point information.
