According to preferred embodiments of the present invention, an image signal processing apparatus for converting an interlace signal which creates a frame image by alternately displaying an odd field and an even field on a single screen into a progressive signal, includes a line memory for storing the interlace signal, a writing/reading portion for writing/reading the interlace signal into/from the line memory, a signal generation portion for generating a prescribed signal, a selector for selectively outputting the interlace signal from the line memory or the prescribed signal from the signal generation portion, and a controller for controlling signal selection by the selector. The controller controls the selector such that, when the odd field of the interlace signal is being read from the line memory, the interlace signal is outputted from the line memory to odd lines of a progressive signal to be converted and the prescribed signal is outputted from the signal generation portion to even lines of the progressive signal, and when the even field of the interlace signal is being read from the line memory, the interlace signal is outputted from the line memory to even lines of the progressive signal and the prescribed signal is outputted from the signal generation portion to odd lines of the progressive signal. |
