摘要： A focus detection device includes a focus detector, an object detector, a selector, a divider, and a controller. The focus detector is configured to detect a plurality of focus adjusting states at focus detecting positions in an image plane of an optical system. The object detector is configured to detect image information corresponding to a specified object in an image of the optical system. The selector is configured to select focus adjusting states among the plurality of focus adjusting states based on the image information detected by the object detector. The divider is configured to find variation in the selected focus adjusting states and configured to divide the selected focus adjusting states into a plurality of groups based on the variation. The controller is configured to find a final focus adjusting state based on a pre-final focus adjusting state in a group selected from the plurality of groups.

摘要： An auxiliary light projection apparatus used for focus detection has a laser beam generating device and a diffraction plate for diffracting a laser light from said laser beam generating device. The diffraction plate has micro lenses regularly arranged in vertical and horizontal directions. The curvature of each micro lens in the vertical direction is different from that in the horizontal direction. The pitch of arrangement of the micro lenses in the vertical direction is different from that in the horizontal direction. In addition, the height of the micro lenses is varied cyclically. The auxiliary light projection apparatus projects a diffraction light pattern of the laser light emergent from the diffraction plate to an object to be photographed, as a pattern used for focus detection.

摘要： A can lid of the fully-open type has a disk-shaped panel, a score notched endlessly in a surface of the panel along an outer circumferential edge of the panel, for forming an opening in the panel, and a tab fixed to the panel by a rivet. The tab is attached in a direction substantially perpendicular to an initial tear-off line of the score. The surface of the panel which is concealed from view by the tab is printed with a circular mark representing a rolling direction in which the material of the panel has been rolled. The score is defined such that the rolling direction extends substantially at a right angle to the initial tear-off line of the score. The panel has an auxiliary score defined in the surface thereof near the rivet and positioned across the rivet from the initial tear-off line substantially parallel to the initial tear-off line and separate therefrom.
