Abstract

PURPOSE:To give interpolation to the lost area based on the addresses of picture elements before and after the interrupted area, by deciding that the supplied data is lost partially and the segment is interrupted. CONSTITUTION:The differential data DELTAY the DELTAX are obtained through arithemtic part I14 between a light pen address register parts I12 and II13. An interpolation deciding part 15 delivers an output to an AND circuit part 18 when DELTAX or DELTAY is equal to the values other than + or -1, and an interpolation request signals is applied to an interpolation control part 17 via a latch part 19. While the address of the picture element to receive an interpolation is calculated at an arithmetic part II16. Based on this arithmetic result, the part 17 supplies the data of the mis-written picture element into a memory part 5. As a result, a monitor is always given to both the address of the picture element supplied newly and the address supplied precedently. Then the picture element is newly interpolated to secure continuation to the picture elements supplied before and after in case a discontinuous point arises.
