PURPOSE:To express information independently of the input/output accuracy of an input and output device, by performing the operation as to a coordinate of a boundary between black dot run and white dot run, converting the result into the coordinate in binary expression and compressing the information of binary pattern. CONSTITUTION:A counter value in a dot counter 7 is incremented by +1 into ''19'', and ''247'' and ''19'' are compared depending on the content of a memory 2. Thus, the operation of two cases in dot change (transition), white dot white dot and black dot black dot, or white dot black dot and black dot white dot, is repeated over all binary patterns, and after the 248-th dot of the 204-th line is read in a dot discriminating circuit 6, a counter of the dot counter 7 is incremented by +1 into ''247'' and it is compared with the value subtracting ''1'' from the content of the memory 2. when the comparison is made coincident, the counter in a line counter 10 is incremented by +1 into ''204'', the content of a memory 3 is compared with ''204'' and when they are coincident, this operation is stopped. |
