摘要： A camera which has a photo-taking lens capable of zooming, and a viewfinder which shows a first photographing range and a display which displays one frame defining a second photographing range smaller than the first photographing range, wherein out of photographing range showing mode is provided. And when the out of photographing range mode is selected, after zooming operation is carried out, the second photographing range is exposed on a film, whereby the visual field in the finder can be enlarged and, provided that a camera has a focus detector, the focus detecting area can be relatively enlarged.

摘要： A display system for displaying information in the viewfinder of a camera, capable of displaying a positive pattern indicating a distance measuring area and a light measuring area on a transparent background so that a photographing field can be seen through the transparent background of the pattern. The display system comprises a liquid crystal display of a guest-host type disposed near the focal plane of the optical system of the viewfinder. The liquid crystal display comprises transparent electrodes provided with a pattern indicating distance measuring areas and light measuring areas, a liquid crystal of a cholesteric-nematic phase transition type having a negative anistropic dielectric property as host, and a dichroic coloring matter having an anisotropic light absorption property as guest. The pattern having a high opacity is displayed on a transparent background in the viewfinder in a satisfactory contrast to the background.

摘要： A camera is capable of switching normal photographing mode and panoramic photographing mode to each other and has a view finder for checking a photographing range. The view finder includes a visual frame display device, a device for varying magnification of the view finder, a control device. The visual frame display device switches a visual frame for displaying the normal photographing mode and a visual frame for displaying the panoramic photographing mode. The control device switches the visual frame display device from the visual frame for displaying the normal photographing mode to the visual frame for displaying the panoramic photographing mode and allows the magnification varying device to increase the magnification of the view finder. Instead of the control device, in switching the normal photographing mode to the panoramic photographing mode, the control device also instructs the magnification varying device to vary the magnification of the view finder so that either an angle of view corresponding to a horizontal direction or in a vertical direction in the panoramic photographing mode is displayed in the visual frame for displaying the normal photographing mode and then, instructs the visual frame display device to switch the visual frame for displaying the normal photographing mode to the visual frame for displaying the panoramic photographing mode, and the view finder magnification varying device to vary the magnification of the view finder.

摘要： Brightness of a central area in a scene to be photographed and brightness of a peripheral area around the central area are measured, and the brightnesses of respective areas are outputted as first and second values. When the second value is larger than the first value, the first value is corrected by a value which has no relation with the respective measured values. Consequently, a proper controlling brightness value is provided for controlling the exposure.
