<p>PROBLEM TO BE SOLVED: To provide a print image that image information contained in the 1st digital image information and lower than the nyquist frequency of that digital image information is visually completely restored. SOLUTION: The information quantity of 1st digital image information 1 is increased by an image processing means 4, and 2nd digital image information 2 is provided by reducing the frequency component, which is contained in the 1st digital image information 1, higher than the nyquist frequency of the 1st digital image information 1. Then, a high-density recording means 5 records the 2nd digital image information 2 with the density higher than that of sampling in the case of providing the 1st digital image 1 from the original.</p> |
