A video standards converter in which digital persistence is effected by including first and second picture stores (22). First and second coefficient blocks (300, 302) are connected to the first and second stores respectively and the outputs of the blocks added in an adder (301). Coefficients are selected for use in each block to determine the portion of information passed on to the adder. These coefficients may be varied cyclically and/or in dependence on any picture movement to provide variation in the degree of persistence applied. <IMAGE> |
