Abstract
PURPOSE:To increase the degree of freedom as to mask selection in mask processing and also to reduce a mask coefficient storage memory, by generating the unit of each sampling-point sequence for mask generation in the form of relative addresses by use of ROM. CONSTITUTION:The output of counter 2 counting a clock signal from line 510 is used as the address of ROM3 stored with various units of sampling-point sequence with an equal Euclid distance from the center of the mask. Address data at sampling points of the mask are added 4 to the output of absolute address register 1 for mask processing picture elements to be converted into an absolute address, so that the access address of the picture memory can be obtained. Then, data to register 1 are set every time the mask processing of one picture elements ends. Further, coefficient signals of respective sampling points of the mask generated by counter 8, multiplexer 11 and RAM12 are used for arithmetic among picture elements in the mask as coefficients for picture elements by the output address signal of adder 4.
