摘要:
Both a sharp print image and a natural reproduced move image can be obtained from a signal recorded on a recording medium. A recording signal, read from the recording medium, is converted into digital data and is delayed by one field. Data representing the current image in the n-th field and data representing an image in the (n-1)-th field one field ahead of the current image, are applied to a subtracting circuit, to extract a component representing moving image portions. An interpolated image for making movement correction is created from the extracted component representing the moving image portions by an interpolating circuit. Data representing the interpolated image and the data representing the current image in the n-th field are synthesized by a synthesizing circuit, to output composite data as data representing an image which has been subjected to movement correction. Since the image is subjected to the movement correction, a natural reproduced movie image smoothly moving is obtained even when the recording signal is recorded at high shutter speed.
