An apparatus for converting a frame format of a television signal to a display format, comprising:
- scanning format conversion means for converting a scanning format of an input video signal to a progressive scanning type when the scanning format of the input video signal is an interlaced scanning type;
- scanning line conversion means for converting a number of vertical scanning lines of an output video signal from said scanning format conversion means to a number of vertical scanning lines for the display format, said scanning line conversion means including:
- 3:4 line conversion means for converting the number of the vertical scanning lines of the output video signal from said scanning format conversion means to 1050 lines when the output video signal has 787.5 lines;
- 4:3 line conversion means for converting the number of the vertical scanning lines of the video signal from said scanning format conversion means to 787.5 lines when the output video signal has 1050 lines;
- 2:1 line conversion means for converting the number of the vertical scanning lines of the output video signal from said scanning format conversion means to 525 lines when the output video signal has 1050 lines;
- and
- 3:2 line conversion means for converting the number of the vertical scanning lines of the output video signal from said scanning format conversion means to 525 lines when the output video signal has 787.5 lines;
- horizontal pixel conversion means for converting a number of horizontal pixels of an output video signal from said scanning line conversion means to a number of horizontal pixels for the display format, said horizontal pixel conversion means including:
- 3:4 pixel conversion means for converting the number of horizontal pixels of an output video signal from said 3:4 line conversion means in said scanning line conversion means at a ratio of 3:4;
- 4:3 pixel conversion means for converting the number of horizontal pixels of an output video signal from said 4:3 line conversion means in said scanning line conversion means at a ratio of 4:3;
- 2:1 pixel conversion means for converting the number of horizontal pixels of an output video signal from said 2:1 line conversion means in said scanning line conversion means at a ratio of 2:1;
- and
- 3:2 pixel conversion means for converting the number of horizontal pixels of an output video signal from said 3:2 line conversion means in said scanning line conversion means at a ratio of 3:2;
- and
- format control means for controlling said scanning format conversion means, said scanning line conversion means, and said horizontal pixel conversion means to convert a frame format of the input video signal to the display format.
