Abstract:
An automatic focus adjusting apparatus comprising:image move-amount detecting means for detecting, for each of a pair of images of a subject divided in a predetermined direction, image positions of the subject in an image-divided direction and in a direction approximately orthogonal with this image-divided direction respectively on photoelectric conversion elements at mutually different first and second times respectively, and for obtaining move amounts of the images of the subject in the image-divided direction based on a result of this detection;image position predicting means for predicting an image position of the subject in an image-divided direction at a third time different from the first and second times, based on an output from the image move-amount detecting means; andcontrol means for carrying out a focus adjustment so that the image of the subject is in focus at the third time, based on an output from the image position predicting means.
