Abstract:
1. A deinterlacing method for converting an interlaced format into a progressive format, the deinterlacing method comprising: receiving a plurality of previous interlaced video fields; extracting a first previous video field having a field identifier (ID) which is the same as a field ID of a currently input video field from the plurality of previous interlaced video fields; detecting motion by comparing the first previous video field which is extracted with the currently input video field; and interpolating the currently input video field according to a result of the detecting the motion, wherein the deinterlacing is performed without the input of a next field, and only a previous field is referred to for temporal interpolation with respect to the current field, wherein the first previous video field is a video field preceding the previous video field of the currently input video field which is not temporarily adjacent to the currently input video field, and wherein the detecting comprises detecting motion by using motion detection results that have been obtained for previous video fields preceding the first previous video field and a motion detection result for the currently input video field.
