Abstract
An apparatus and method for processing moving image data so as to obtain stationary image data representative of a desired image frame which is suitable for display on a display device. A moving portion of the image data corresponding to the desired image frame is detected and the image data corresponding to the detected moving portion is interpolated in accordance with a predetermined interpolation technique. A stationary image corresponding to the interpolated image data may be displayed on the display device with relatively high quality. The motion detection and field interpolation processing may eliminate or reduce stripes or the like which may otherwise be present in the displayed stationary image due to a deviation of the image data between the fields of the respective frame. Coefficients utilized for the motion detecting processing may be taken from previously stored values or may be set by an operator.
