Abstract
Abstract A system and method for generating timing signals in an electronic imaging device includes a horizontal timing generator with a first programmable memory for storing a set of timing information and a vertical timing generator with a second programmable memory for providing a set of control information which is used to selectively generate the timing signals from the set of timing information in the first programmable memory.
