摘要:
An auto focus camera includes a usual zoom lens and provides a pseudo focal length mode, in which the size of focus condition detecting area, to the photographing scene to be printed, is variable. A pseudo focal length is stored and a focus condition is detected in accordance with a ray of light passed through the zoom lens. When the camera is in such a mode as to continuously detect focus condition for keeping an object in focus, or to be operated when the contrast of the object whose focus condition is detected is low, the focal length of the zoom lens and the pseudo focal length are controlled respectively in accordance with the mode.

In a camera having a function or recording a scope of printing (printing scope) in an exposed picture of a film, under a panoramic photography mode, that is, a mode in which the ratio of the horizontal dimension to the vertical dimension of a printing scope is larger than that of a standard picture from a film, an aperture is controlled to be smaller than in standard photography.

A lens driving controller has a driving mechanism for driving a lens along an optical axis, a calculator for obtaining a lens driving amount to an in-focus position, and a detector for detecting a position of the lens. The controller drives the lens in an in-focus direction in accordance with a lens driving amount obtained by the calculator, drives the lens in an opposite direction when the lens reaches a first lens position where a remaining driving amount to the in-focus position is a predetermined value, obtains information on a second lens position when the lens actually starts to move in the opposite direction, obtains a lens movement amount from the first lens position and the second lens position and performs remaining driving to the in-focus position and stop control based on an obtained lens movement amount.

An automatic focusing camera according to the present invention is an automatic focusing camera having a plurality of operation modes, including an information input device for entering a plurality of types of photographing information, an information analyzer for analyzing the photographing information entered by the information input device based on a fuzzy inference, and a mode determining device for determining one of the operation modes based on the result of the analysis of the information analyzer.
摘要:
An apparatus has an automatic focus detection device. The automatic focus detection device detects a focus condition of a taking lens by using a plurality of detection areas. These detection areas are displayed on a finder. The plurality of detection area are displayed on the finder in a specific order according to a situation of the camera by throwing a switch designating a detection area.
摘要:
An electronic appliance having a microcomputer, peripheral devices controlled by the microcomputer, a main battery acting as power source, and a backup battery for outputting signals indicating the presence and absence of the main battery. Checking is made of whether the main battery is loaded in the appliance or not and whether the output voltage of the main battery is above a predetermined voltage or not. When the main battery is not loaded or when its output voltage is below the predetermined voltage, the backup battery is made available for preserving information in the memory inside or outside the microcomputer in good order, with operations of the peripheral devices being restricted at such times. Further, the disclosed electronic appliance provides for limiting malfunctioning of the microcomputer and the peripheral devices when a new main battery has been loaded in the appliance as replacement for an exhausted main battery.
