摘要

This convertor comprises:… (a) a spatial filtering circuit which is an interpolation circuit (30);… (b) a selection circuit which comprises a first memory (10) delaying the input signal by the duration of one image, a second memory (20) delaying the output from the first memory by the duration of one image, two first and second delay circuits (40 and 50), and a sorting circuit (60) receiving on its three inputs respectively the output signal from the second delay circuit, the output signal from the interpolation circuit, and the output signal from the first delay circuit;… (c) a circuit for reconstructing the final image which comprises a third delay circuit (70) and a multiplexing circuit (80). …IMAGE…
