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： An apparatus and method of adjusting an auto focus are provided. The apparatus includes: an imaging pickup device for generating an image signal by capturing light passing through an imaging lens; a shutter for controlling light exposure of the image pickup device; a focus detector that calculates a contrast value from the image signal and detecting a focus from the contrast value; and a release controller for controlling a release operation constituting a photographing operation of a still image, wherein the release controller includes, as driving modes, a first mode that directs a focus lens included in the imaging lens to be driven while driving the shutter, and a second mode that directs the focus lens not to be driven while driving the shutter. Accordingly, a photographing time is reduced.

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 calculates amount of defocus of an object, and repeatedly calculates the speed of the image plane of the object based on the amount of defocus. When releasing operation of the camera is started, image plane speed of the object at the time of exposure is estimated by using a secondary curve based on the speed of the image plane, and the lens is driven based on the data thereof. Since the image plane speed of the object is estimated by using the secondary curve equation, correction of the amount of defocus can be accurately done regardless of the speed of movement of the object.
