摘要:
Method for reversing a video signal having sequences of n elements comprises the steps of writing the n elements of a first sequence into memory locations of a memory in a non-reversed order and reading out the memory locations in a reversed order, and in a subsequent step, writing the n elements of a second sequence into the memory locations in a reversed order and reading out the memory locations in a non-reversed order. The memory locations are readout from the memory in particular one element ahead of the write locations of the memory. A method of this kind can be used in particular in a television camera comprising a lens unit, which is designed for film applications.
