摘要： A method and apparatus is provided for the conversion of non-interlaced image data to interlaced image data while reducing flicker effects and simultaneously scaling the image data. A programmable discrete time oscillator (DTO) dynamically determines coefficients that are used in reducing flicker and vertical and horizontal scaling. The two functions are integrated which allow the flicker filter coefficient generated by the DTO to dynamically be modified and take into account desired vertical scaling. A similar DTO is provided to separately perform horizontal scaling using the dynamic coefficients.
