Abstract

PURPOSE:To obtain high resolution by mutually dislocating field picture data to form reading data only by a line number to correspond to an enlarging multiple or a reducing multiple. CONSTITUTION:Until reading data DATAOUT are obtained by writing writing data DATAIN to an image memory 13 and reading the said written picture data, the reading data DATAOUT, which are composed of odd number field picture data A, B... to express an enlarging picture and even number field picture data (a), (b)..., are obtained by overlapping the writing data DATAOUT. A relation between a displaying position in a vertical direction on the display screen of the odd number field picture data A, B... and the displaying position in the vertical direction on the display screen of the even number field picture data (a), (b)... is dislocated only by a line number (m) to correspond to an enlarging multiple (n) of the enlarging image. Thus, the converted picture can be obtained without feeling to be unnatural.
