PURPOSE:To form a reconstituted image in an area for video formation rapidly and simply by an aperture synthesizing method by processing digital hologram data by prescribed kernel data to form the reconstituted image. CONSTITUTION:The digital hologram data stored in a cosine buffer 8 and a sine buffer 9 are read into a computer 10 and processed together with the data from the built-in ROM to determine the reconstitued image data. The kernel data are formed by a value of which absolute value is expressed by 2<n> (n: integer) or ''0'' or the data obtained by encoding these values and the digital hologram value is used as it is, inverted at its polarity, shifted at its bit, or substituted by ''0'' in accordance with the kernel value, so that the arithmetic is executed rapidly and simply. Consequently, the reconstituted image in the area for video formation can be formed rapidly and simply by the aperture synthesizing method and can be displayed. |
