A camera, such as a video camera or other electrically recordable camera, has scale imprintable capabilities and a method for imprinting a scale onto memory storage media. The camera and method imprints, optically or electrically, a standard scale on memory storage media for the purpose of estimating the size of a subject image. A photographic magnification calculation circuit calculates the photographic magnification based on a subject distance, and a reference scale setting circuit sets a reference scale for the purpose of estimating the size of the subject image on the memory storage media regardless of the magnification during picture taking or print size. An imprinting circuit imprints, optically or electrically, the reference scale onto the memory storage media in accordance with the reference scale setting circuit, and only when needed or wanted. The reference scale can be imprinted in a vertical or horizontal direction in accordance with a mode selection switch. In addition, date, time and other information can also be imprinted onto the memory storage media. Picture taking will not be performed when it is not possible to accurately superimpose the reference scale and warning displays are generated.
