PURPOSE:To correctly obtain a correction command to instructing data and to effectively weld by changing the setting of a coefficient set to a convolution integrator. CONSTITUTION:Plural picture element data storing parts 20-1-20-n for storing the data of one picture element of digitized picture data are provided and a picture data storing shift register 20 for fetching the picture data by a shift signal and sequentially shifting is disposed. Coefficient storing parts 30-1-30-n in which the coefficient is set by a digital value the setting of which can be changed disposed correspondingly to the respective picture element data storing parts 20-1-20-n, multipliers 40-1-40-n in which the picture element data stored in the respective picture element data storing parts 20-1-20-n is multiplied by the coefficients set to the corresponding coefficient storing parts 30-1-30-n and an adder 50 for adding the outputs of the respective multipliers are provided. In such a way, a convolution integration is carried out according to a digital processing and the coefficient can be changed. |
