PROBLEM TO BE SOLVED: To improve picture quality by sampling (n) images for obtaining (n) digital images including (j) image lines as a whole, applying a dither algorithm to each of the (n) digital images, cutting this into (n) strips including the same number of lines and interleaving the strips for constituting an image. SOLUTION: It is desired that (q) arrayed cylindrical lenses are used for forming a horizontal network. A recorded image is constituted of (n) interleaved digital images and has (j) pixel lines. In this case, each of (n) images is sampled in order to obtain (n) digital images 21a-21c including (q) pixel lines as a whole. Then, those images are converted into (n) dither images 22a-22c by a dither algorithm and each image is cut into (q) strips 23a-23c. The size of the strip is set so that the total of the pixel lines should be equal to j/q. |
