Abstract
The present invention provides an image signal processing apparatus and a method thereof which shifts positions of each detected pixel in image signals generated by performing double-speed conversion, wherein a difference value in pixel signal level between a detected pixel in a current field and a detected pixel at the same position in a field which comes one frame behind the current field is calculated, to specify a first field, a motion vector for a field which comes one frame or two frames behind the current field is detected with respect to the detected pixel in the current field, interpolation pixel data for the detected pixel is calculated based on the detected pixel in the current field and the each pixel in the field which comes one frame or two frames behind the current field, the interpolation pixel data is disposed in the pixel position obtained by shifting the position of the detected pixel in the current field in a direction along the motion vector, in a field subsequent to the first field, and the shift amount is sequentially increased every time the field shifts from the first field to the following fields within a range of a vector quantity of the detected motion vector.
