Patent ID: 7286160

Claim:
A method for image data print control, comprising: obtaining subject image data which is obtained by capturing an image of a subject formed through a photographic optical system and output by an image-capturing element having a plurality of pixels; obtaining a distance to the subject; obtaining a number of pixels provided at the image-capturing element; obtaining a pixel pitch at the image-capturing element; obtaining a focal length of the photographic optical system; calculating a printing resolution so as to print the image of the subject in a size equal to a size of the subject by using the subject image data, based upon the distance to the subject, the number of pixels at the image-capturing element, the pixel pitch at the image-capturing element and the focal length of the photographic optical system; storing the printing resolution into a storage area together with the subject image data; and selectively displaying the subject image captured by the image-capturing element and a subject image based upon the subject image data stored in the storage area, wherein: a display magnification factor representing a ratio of a size of a display range and a value obtained by dividing the number of pixels by the printing resolution is displayed together with the subject image.
