A single-collapsible-lens reflex camera includes a lens barrel designed such that it is moved forward into shooting position from the camera body when in use and at least its part is collapsed in the camera body when not in use. A shutter release button is provided to shoot a subject when pressed. Electromagnets for controlling the leading and following curtains of a focal plane shutter are deenergized before the shutter release button is pressed and energized when the button is pressed. A mirror drive member raises or lowers a movable reflex mirror when a subject is shot and the lens barrel is collapsed. A shutter charging member moves the focal plan shutter in the direction that charges the focal plane shutter in synchronism with the operation of the mirror driving member to raise the mirror and in the direction that discharges the shutter in synchronism with the operation of the discharges driving member to raise the mirror. A control circuit deenergizes the shutter leading-curtain controlling electromagnet when the mirror is raised, deenergizes the shutter following-curtain electromagnet after a length of time depending on the intensity of light reflected from a subject to be photographed, and keeps the leading-curtain and following-curtain controlling electromagnets deenergized when the mirror is raised to collapse the lens barrel. Thereby, the shutter is shifted to the non-charged state as it is closed when the lens barrel is collapsed.

A light-emitting element is arranged in a camera body to emit light toward part of the face of a user. A light-receiving element receives light reflected by the face. A detection unit detects shaking of the camera body on the basis of a change in photocurrent from the light-receiving element. The light-emitting element and the light-receiving element may be arranged as an eyeball detection unit for detecting the position of the eyeball of the user.

A digital fuzzy inference apparatus performs fuzzy inference by time-divisional control. A latch circuit latches an input signal. A parameter storage circuit stores a plurality of sets of parameters for defining membership functions constituting a plurality of fuzzy rules. A parameter switching circuit sequentially and selectively outputs one of the plurality of sets of parameters from the parameter storage circuit in accordance with a clock pulse. Every time one set of parameters are output from the parameter switching circuit, a single operation circuit performs a fuzzy rule operation with respect to the input signal stored in the latch circuit by using a membership function defined by the parameters, and outputs a degree to which the input signal meets the rule. An operation result storage circuit stores the output from the operation circuit at a storage position designated by the output parameters. A center-of-gravity calculator obtains the center of gravity of values stored in the operation result storage circuit when all the fuzzy operations based on the plurality of sets of parameters are completed.

An instruction for returning to a ROM is written to a position where data is not broken even if a next correction is executed in order not to the content of a register even if an interruption processing for correction and a processing for returning a ROM program are executed. A microcomputer connected through a serial i/O bus, an EEROM, and a correction data writing device comprises a CPU, a RAM, a ROM, a PC comparison register section, a ROM correction processing circuit having a PC value latch section, and a serial i/O section. The CPU sequentially executes an internal sequence control of the microcomputer and a logical operation in accordance with instructions written in the ROM as a program in advance. The RAM temporarily saves intermediate processing data of, e.g. calculation, or saves an adjustment value transferred from the EEPROM when the program is actually executed.

A camera which reduces camera shake by adjusting the shutter timing is characterized in that it has a mode for displaying a camera shake amount to allow a photographer to recognize a camera shake. A shutter timing determining section permits shutter release at a timing at which the camera shake amount becomes a predetermined amount or less during a shutter release operation on the basis of the camera shake amount detected by a camera shake detecting section. When a camera shake learning mode is set through an input section, a camera shake amount is converted into a display amount by a display data converting section through a camera shake mode selecting section. This display amount is displayed on a display section in real time while a shutter release button is depressed. The camera shake selecting section inhibits a shutter driving operation of the shutter timing determining section in the camera shake amount display mode, thus also allowing a photographer to learn how to depress the shutter release button without causing a camera shake.

A digital fuzzy inference system has fuzzy inference processors each of which is provided for each of fuzzy rules and comprises if-part membership function defining circuits, a minimum-value calculation circuit and a then-part membership function defining circuit. Each of if-part inputs is supplied to a corresponding if-part membership function defining circuit in which the if-part membership function is defined in accordance with definition parameters and the membership value is calculated by referring to the defined membership function and the input value. For each of the rules, membership values are entered into the minimum-value calculation circuit to select their minimum value. The minimum value is applied to the then-part membership function defining circuit which defines a then-part membership function in accordance with definition parameters and a then-part input. Then-part membership functions for all the rules are synthesized through maximum-value calculation by a membership function synthesizing circuit. The result of synthesis serves as a fuzzy inferential result. For a fuzzy controller for controlling a controlled object in accordance with the inferential result, the center-of-gravity calculation circuit calculates a value of the center of gravity from the synthesized membership function because the inferential result needs one definite value.

A shake amount detecting section repeatedly detects shaking of a camera in a sampling time interval shorter than a hand shaking cycle. An exposure calculating section calculates a shutter speed based on the sensitivity of a film and the brightness of an object. A data processing section acquires processed data from a product of the shutter speed and the amount of shaking, every time the amount of shaking is detected. A storage section stores the processed data output. A shake amount predicting section receives the processed data and the processed data stored in the storage section to predict the total amount of shaking while the shutter is open, every time the processed data is output from the data processing section. A release switch instructs the beginning of an exposing operation on the film. A shutter enable discriminating section discriminates permission of a shutter release when a latest predicted total amount of shaking during shutter opening, output from the shake amount predicting section, is equal to or smaller than a predetermined amount, every time the release switch is operated and the shake amount predicting section predicts the total amount of shaking. A shutter controller starts opening the shutter based on a signal from the shutter enable discriminating section and controls an exposure time based on the shutter speed.
