Abstract

PURPOSE: To obtain a picture of high resolution by sampling again picture elements, sampled in the directions of 2M rows by 2N columns on a screen, in the directions of M by N and by counting the number of changes in information from black to white and from white to black so as to determine whether the information should be outputted.
CONSTITUTION: A two-dimentional picture is stored in one-by-2N per unit memories M1 to M2M by row controller 1 and column controller 2 via multiplexer 3. The picture information stored in the memories is passed through multiplexers 3 and 5 to make four picture elements into one, which is stored in M-by-N memory 4. When information is transferred from 2M-by-2N memories M1 to M2M to small memory 4 over arithmetic, counter 6 counts the total of differences in content between adjacent picture elements. The content of small memory 4 that the largest value is indicated among four counters 6 is extracted from gate 8 under the control of controller 7 to obtain an output picture. Consequently, the output picture of sufficient resolution can be obtained.
