摘要： A camera acoustic indicating device for indicating, by sound, attainment of an in-focus condition of a camera objective lens and warning possibility of a blur occuring exposure time due to low brightness of an object to be photographed. The sound for the in-focus indication is intermittently generated at a frequency higher than that at which the sound for the blur warning is intermittently generated. When the attainment of an in-focus condition is detected while the blur warning is being made, the warning is interrupted for a given time period during which the attainment of the in-focus condition is indicated for a short time.

摘要： A camera has an exposure control unit and a focus control unit. The exposure control unit selectively provides a programmed exposure control mode, where an aperture value and a shutter speed value are automatically set based on a detection by a light metering sensor and an accordance with a preset program, and a manual exposure control mode where at least either of the aperture value and the shutter speed value is set manually. The focus control unit selectively provides an autofocus mode where a focusing is automatically effected based on a detection by a focus sensor and a manual focus mode where the focusing is effected manually. The invention is characterized by a feature which permits a forcible switchover of the focus control mode from the manual to the auto focus mode in response to a switchover of exposure control mode from the manual to the auto exposure mode.

摘要： A camera accessory such as an exchangeable lens or an electronic flash device, selectively attached to a camera and having a driven member and an encoder for the driven member. The encoder having a pattern for position adjustment and a brush linked with the driven member, the encoder being constructed to produce code data indicative of the position of the brush on the pattern. The camera accessory outputs a signal indicative of a relationship between the driven member and encoder on the basis of the data from the encoder, the signal being used for the position adjustment.

摘要： An exchangeable lens to be mounted on a camera body by the rotation of the lens barrel is provided with a plurality of terminals arranged circularly along the circumference of the lens barrel about the optical axis of the lens barrel and are connected to a CMOS circuit in the lens. The terminals include a power supply terminal and a ground terminal through which electric power is supplied from the camera and a signal terminal through which a signal is transmitted between the camera body and the lens. The power supply terminal and the ground terminal are arranged to come into contact with their corresponding camera terminals in advance of the signal terminals when the lens is rotated to mount it on the camera body.

摘要： A photographic camera having a photographic operating device including a focus detecting circuit, a shutter control circuit, a light measuring circuit and a light emission control circuit, an adjustment data memory for storing adjustment data based on functional characteristics of the respective circuits of the photographic operating device and an adjustment circuit for adjusting the respective circuits by using adjustment data read from the adjustment data memory. The adjustment data memory is consituted by an EEPROM for making it possible to conveniently and readily rewrite the adjustment data. The adjustment data is calculated from a linear function expression established between a design value and an actual value for avoiding trial-and-error preparatory operations for the adjustment.

摘要： A camera system comprises one or more than two intermediate accessories and the number of the attached intermediate accessories is checked. When the intermediate accessories of more than the permitted number are interposed in the camera system, the automatic focusing operation is prohibited. Therefore, a large driving torque does not occur so as to prevent the bad effect on the camera driving system.
