摘要： A focus detection condition display device suitable for use in a camera provided with an electronic viewfinder. The pattern signal corresponding to a focus detection zone on which focus detection is conducted by a focus detecting system is superimposed on the video signal of the object field and said signal is output to an electronic viewfinder. When the focus detection has become impracticable for such reason as lack of contrast of the object field, or focusing has become impracticable because of the object coming too close to the camera, an alarm is issued by the pattern corresponding to a focus detection zone displayed on the electronic viewfinder displaying in a manner different from that ordinarily used.

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 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.
