Abstract
An information recording device capable of preventing a deterioration of quality of a display image. Pixel counts in each of a horizontal direction and a vertical direction of an image represented by digital image data generated by a CCD, are greater than in an image for which electronic zoom has been implemented. A zoom rate of the electronic zoom to be applied to the image during execution of dubbing of an image file and/or display by an LCD of an image represented by the image file, is limited to not more than a magnification rate upper limit value, which is determined on the basis of the horizontal and vertical direction pixel counts of the image represented by the digital image data generated by the CCD and pixel counts in the horizontal and vertical directions of the image for which the electron zoom has been implemented.
