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).
