When displaying operational settings and measurements on a pointer type display device, the starting position of the needles is automatically adjusted even when there are battery exchange and needle drive process errors. The display device may be used to display physical quantities using pointers which move above scale plates. Even though the displays may be changed by electric supply loading, battery exchange or a fall in electric supply voltage, the display can be automatically corrected. A memory stores the movement destination position of the pointers, and instructions are generated by a controller which calculates the movement destinations of the pointers after the electrical supply voltage is stabilized properly. The instructions which control operation of a driver for the pointers preferably use a combination of movement to predefined positions and incremental movement. This minimizes the number of instructions when moving automatically, while enabling the pointers to follow movement of operator controls.

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. Further, when the photography command signal is input from the release switch assembly without any substantial time lapse after the preparation for photography signal is input therefrom, the brightness of the object to be photographed is measured and an exposure value is calculated therefrom, the focus adjustment state of the photographic lens is detected, thereafter focus adjustment of the photographic lens is performed, and thereafter exposure of the film is performed according to the exposure value.

A needle-type display device for displaying photographic data in a camera, the display device including a display having indicating needles which move directly from displaying presently displayed values to displaying new values without temporarily returning to an origin position. The display device includes a half-press switch having first and second positions, and a rangefinder and photometric unit which operate when the half-press switch is in the first position. The display displays photographic data measured by the range finder and photometric unit according to an amount of movement from an origin position by the respective indicating needles. When the half-press switch switches to the second position, a hold command unit operates to hold the respective indicating needles for a predetermined period of time at the display position displaying the measured amount. When a new measurement is performed by the rangefinder or photometric unit during the hold period, an update command unit moves the indicating needles directly from their present positions to new positions without returning to their origins. By the indicating needles moving directly to new display positions, the time required for the display needles to move is reduced, and a quick display response to measured photographic data is possible.

A camera is provided with several displays illuminated by several illuminators which are controlled to be turned on and off in dependence upon the operation of several illuminator buttons. Further, the brightness of the illuminators, when turned on, may be determined according to the operation of the illuminator buttons and according to the brightness of the object to be photographed.

An electronic camera includes: a substantially rectangular parallelepiped image-capturing unit main body provided with an image-capturing device for generating an image signal by capturing an optical image formed by a photographic lens unit; a substantially rectangular parallelepiped display unit main body provided with an external display device for displaying an image based upon the image signal generated by the image-capturing device; and a linking portion that links the image-capturing unit main body and the display unit main body in a manner that the image-capturing unit main body and the display unit main body can rotate relative to each other. And, at the display unit main body, a shutter release button is provided and a grip portion is provided near an end surface furthest away from the image-capturing unit main body; and at the image-capturing unit main body, an optical viewfinder unit is provided beside the photographic lens unit.

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).
