Variable camera viewfinder corresponding to variable camera aperture

Abstract

A camera selects one of three or more photograph image sizes to be printed while a viewfinder provides a visual display corresponding to the selected one photograph image size. The camera includes a photographic optical system which focuses a subject on a camera film. A control unit is incorporated within the camera to select first print size information, second print size information, and third print size information. A viewfinder within the camera verifies the field to be printed on the photographic film while a display inside the viewfinder corresponds to the selected photograph image size. Print size selection switches select the print size and the control unit selects the print size information in response thereto. A plurality of aperture blades disposed within the camera define an aperture frame. First and second aperture blades move inwardly to define a horizontally oblong photograph image size and third and fourth aperture blades move inwardly to define a vertically oblong photograph image size. All aperture blades move outwardly to define a standard image size. A plurality of liquid crystal display segments are disposed within the viewfinder to define a variable viewing area corresponding to the selected image sizes. A control unit selects the image size in response to a switch.
