Abstract: When a preparation for photography signal is input from a release switch assembly without said photography command signal being input therefrom, the brightness of an object to be photographed is measured and an exposure value is calculated therefrom, the focus adjustment state of the photographic lens is detected, and these values are displayed. At the time point when this display operation has been completed, if and only if the preparation for photography signal is still being input from the release switch assembly, focus adjustment of the photographic lens is performed based upon the detected focus adjustment state.

Abstract: A display apparatus in a camera for displaying photographic information using rotating elements. The display apparatus includes a rotating setting dial to rotatively set photographic information, and a display unit including pointers and pointer scales to display the photographic information set by the rotating setting dial. The pointer rotates about a fixed pointer scale in order to indicate photographic information on the pointer scale as set by the rotating setting dial. The display apparatus further includes a detector to detect a direction of rotation of the rotating setting dial, a drive unit to rotate the pointer, and a control unit to control the drive unit to rotate the pointer in the same direction as the direction of the rotating setting dial detected by the detector. In addition, the display unit may include at least one pointer which is controlled by a stepping motor to rotate the pointer in only one direction, regardless of the direction of rotation of the rotating setting dial.

Abstract: A camera having an automatic flash prevention mode includes an override mechanism allowing a photographer to override the automatic flash prevention mode. The number of flashes and timing of the flashes can be set arbitrarily by the photographer while the shutter remains open, without requiring any cumbersome or difficult operations on the part of the photographer. The camera is especially suited for night photography or underwater photography, in which the shutter release button is pressed once to open the shutter and once again to close the shutter.

Abstract: A display device of a camera is automatically switched from a date display mode to a time display mode for a predetermined amount of time in a case when the photographer inputs exposure correction information, such as geographic area information, which involves a correction to account for time change with no change of date. The photographer may thus readily confirm that the time change correction has been made. The order of arrangement of the month, day, and year in the date display mode may be selected automatically according to the geographic area to conform with prevailing custom. The device may incorporate a correction feature to account for daylight saving time and may display a correction code corresponding to the graphic area and a mark indicating that daylight saving time has been selected.

Abstract: A camera records exposure correction information on a recording medium such as a film. The exposure correction information may be based on calendar information, including date information and time information, and geographic information corresponding to the geographic location of the camera. A printing device effects exposure correction based on the recorded information during printing, thereby obtaining a properly exposed print. In a case when the camera itself effects exposure correction, the camera records exposure correction prohibiting information to prohibit exposure correction from being effected by the printing device.

Abstract: A camera capable of operating in a red-eye prevention mode. The camera has an electronic flash device which is activated by a drive circuit in synchronization with the exposure. The electronic flash device also serve as a pre-light-emission device capable of performing pre-light-emission for the purpose of preventing red-eye effect. When it is judged from the photographing condition that red-eye effect may occur, a controller activates the electronic flash device to effect a pre-light-emission for reducing the size of pupils of eyes of a person to be photographed, before the main flashing which is executed in synchronization with the exposure.

Abstract: A camera provides information to a printer to produce a print in which an image of a photographed object is of a desired size. More particularly, the enlargement magnification of a printer is controlled in accordance with information recorded on a recording medium in a camera. Determination of the enlargement magnification involves various parameters including, for example, a specified desired magnification (requested magnification) and photographing magnification, which may be determined by calculation from object distance and focal length of the photographing lens. Modification data may be produced to accommodate changes in photographing angle that accompany focusing of the photographing lens. Focal length or object distance may be varied as required to provide a print image size as close as possible to that desired (and within limitations of the camera).

Abstract: An auto-focus camera with compensation for object movement along the optic axis of the photo-taking lens determines whether the object speed is greater than a predetermined value. If the result of the determination is negative, normal photography is performed in which a combination of shutter speed and aperture diameter provides a proper exposure in accordance with photometric data. If the result of the determination is affirmative, the aperture is stopped down to a predetermined diameter small enough to provide a large depth of field, and flash photography is performed.

Abstract: A camera is capable of recording plural kinds of data at corresponding positions of each film frame. In a first operating mode a first kind of data is recorded at a first position in the film frame disposed at an exposure location, and film feeding is started. Film feeding is suspended temporarily, and a second kind of data is recorded at a second position of the frame. Then film feeding continues to bring a subsequent frame to the exposure location. If no second kind of data is to be recorded or if no data of any kind is to be recorded, the film feeding is not temporarily suspended. Data recording may occur in the course of film winding or film rewinding. Some or all of the data may be stored before recording, and the order of the recording of kinds of data may be changed, e.g., at the last frame of the film. In some embodiments the film is rewound by a fraction of a frame before recording of a second kind of data.

The apparatus determines the optimum exposure value, referring to various conditions including the season and time of photographs, photographing location, sunrise/sunset times and so on.

Abstract: A camera with a built-in self-timer, flash and autofocus is disclosed. The camera is switchable between normal and self-timer modes. When in the normal mode, the auto focus device measures distance at the beginning of a photographic cycle. In self-timer mode, the auto focus device measures the distance at the beginning of the photographic cycle, and after the self-timer has counted down from its set time. A decision to use the flash is based on the first distance measurement and the scene brightness in the normal mode, and on the second distance measurement and scene brightness in the self-timer mode. If the decision is yes, a checking apparatus checks whether the flash capacitor has sufficient charge, and if not charges the capacitor.
