Abstract:
A scanning system converting system for a display unit of a progressive scanning system comprising:a decoder for decoding a coded image data to output a decoded image data and a control data, wherein said coded image data is obtained by coding a first image data, and said control data indicates whether a scanning system of said first image data is a progressive scanning system or an interlace scanning system and whether fields of said first image data are correlated;a transfer section for transferring a second image data to said display unit in response to an effective indication signal;a control section for selectively generating said effective indication signal and first and second control signals based on said control data supplied from said decoder to supply said effective indication signal to said transfer section; anda converting section for selectively outputting, as said second image data, one of a current field of said decoded image data, a previous field of said decoded image data and an interpolated image data for every line based on said first and second control signals supplied from said control section, said interpolated image data being interpolated from said current field of said decoded image data.
