An image signal processing apparatus and method capable of accurately determining a still image and a moving image irrespective of an image pattern represented by input image signals and performing an interlace-to-progressive conversion process suitable for the image type are provided. First progressive-scheme image signals for one frame are generated by performing interpolation or extrapolation calculation on input interlaced-scheme image signals for each field, and second progressive-scheme image signals for one frame is generated by combining the input image signals of the one and the other fields of two adjacent fields. Next, still image determination is performed to determine whether or not an image for one frame based on the input image signals or an image corresponding to each of display regions divided from the one frame is a still image. When it is determined that the image is a still image and it is determined that the image is not a still image, the first and second progressive-scheme image signals are mixed with each other with different mixing ratios to generate the progressive-scheme image signals.
