摘要： Focusing methods, apparatus, and computer-readable recording media having recorded thereon the focusing methods are disclosed. In an example focusing method, a focus evaluation value is divided into first information and second information. The first information represents a difference between focus evaluation values, which are obtained according to location of a focus lens, to be relatively large, and the second information represents the difference to be relatively small. Then, at least one from among the first information and the second information is provided to a user so that the user may easily and more accurately determine whether a subject is in focus.

摘要： A camera according to the present invention comprises a taking lens whose focal length is variable. A focal length thereof is determined based on a subject distance measured by a distance measuring circuit and a relation between a subject distance and a focal length previously stored in a memory or according to a manual operation. The relation stored in the memory is changed based on a focal length determined.

摘要： An automatic focus adjusting apparatus of a camera comprises three CCD sensors receiving light from an object, a focus detecting apparatus for outputting a focus signal indicative of the focusing state of a photographic lens based on output data from the respective CCD sensors, a calculating apparatus for calculating an amount of driving the photographic lens based on the focus signal, a selector for selecting one of the three CCD sensors, a correcting apparatus for correcting the amount of driving calculated based on the output data from the selected CCD sensor, and a driving apparatus for driving the photographic lens to an in-focus position based on the corrected driving amount. An error in foucs detection incidental to the driving of the lens can be corrected based only on the data from one CCD sensor selected by a selector, so that the focusing error on a moving object can be eliminated in a simple manner.

摘要： An autofocusing camera comprises a focus detecting circuit for repeatedly detecting a foucsing state of an objective lens with respect to a photographic object and outputting a focus adjustment signal, and an object detecting circuit for detecting movement of the object in accordance with a plurality of the focus adjustment signals. The lens is driven during a shutter release operation when the object detecting circuit detects movement of the photographic object. The lens drive is prohibited when the object is moving away from the camera.

摘要： An improved focus detecting apparatus comprises a photographic lens, focus adjusting apparatus for driving the photographic lens which has been placed on an initial focusing position to an in-focus position, an auxiliary light emitting apparatus for emitting an auxiliary light and a switch for selecting whether the focus adjustment should be carried out with the auxiliary light emitted or the focus adjustment should be carried out without the auxiliary light. The initial focusing position of the photographic lens can be switched dependent on whether the auxiliary light is emitted or not.

摘要： In an automatic focus detection device for use in a camera, a focus condition detecting unit detects a focus condition of a photographic lens in a camera based on the output of a light receiving device and calculates the amount of defocus of the photographic lens. An auxiliary light emitting device emits auxiliary light and comparator compares the stored output of memory and the output of the light receiving device under the ambient light; and then the detected defocus amount under the auxiliary light emission is corrected in accordance with the result of comparison so as to eliminate the bad effect of the color aberration of the lens of the camera, whereby a correct focus position can be detected.
