An interlaced image processing module and corresponding method facilitate improved processing of interlaced motion images. In one embodiment, the interlaced image processing module receives image data frames having interlaced first and second fields and produces a reference field and error field. The reference field corresponds to the still image content of the interlaced frame, whereas the error field corresponds to the motion content of the interlaced frame, particularly the motion between fields. Motion between fields is thus represented in the error field, without redundant representation of the still image content provided by the first field. Where there is little motion between fields, the error terms will be small so the predictor preserves the coding efficiency provided by any auto-correlation in the image. Further, the interlaced image processing method does not rely upon pixel group classification, and thus avoids classification errors, and the loss of coding efficiency from still image content in motion classified blocks. Finally, problems presented by relative motion between fields are avoided, as are local artifacts. Another embodiment transforms the interlaced fields into frame data having a high frequency field and a low frequency field.

Techniques and tools for joint coding and decoding of reference field selection information and differential motion vector information are described. For example, a video decoder decodes a variable length code that jointly represents differential motion vector information and a motion vector predictor selection for a motion vector. The decoder then reconstructs the motion vector based at least in part on the differential motion vector information and the motion vector predictor selection. A video encoder performs corresponding processing.

Techniques and tools for signaling the number of reference fields for an interlaced forward-predicted field are described. For example, a video decoder processes a first signal indicating whether an interlaced forward-predicted field has one or two reference fields for motion compensation. If the first signal indicates the interlaced forward-predicted field has one reference field, the decoder processes a second signal identifying the one reference field from among the two reference fields. On the other hand, if the first signal indicates the interlaced forward-predicted field has two reference fields, for each of multiple motion vectors of the interlaced forward-predicted field, the decoder processes a third signal for selecting between the two reference fields. A video encoder performs corresponding signaling.

An apparatus and a method for converting image signals from an interlaced scanning format to a progressive scanning format are disclosed. Additionally, an apparatus and a method for changing a vertical scanning rate of progressively scanned image signals are also disclosed. Field motion estimator estimates field motions between a current field and reference fields to find an optimal reference field. Then a field motion compensator restores a missing line of the current field using information given from the optimal reference if the optimal reference field unevenly matches to the current field. Otherwise, a linear interpolator restores the missing line of the current field by linearly interpolating lines located adjacent to the missing line in the current field. Furthermore, a frame motion estimator estimates frame motions between adjacent frames using the progressively scanned image signals and field motions estimated in the field motions estimator. Finally, a frame motion compensator provides a new composite image between the adjacent frames using the frame motions estimated.

It is determined whether each block (51) including a plurality of pixels extracted from a basic field (30) has an edge or not, and then which state, stationary or non-stationary, each of the pixels forming together the block (51) determined to have an edge is. There is calculated an absolute value of a difference between a pixel determined to be non-stationary and a pixel (91 or 92) in each pixel position in a reference field (40) or pixels (82 to 85) included in the reference field and adjacent to the non-stationary pixel, and a correlation is found between such pixels in consideration according to the calculated difference absolute-value. A motion vector is determined by the block matching method according to results of the determination, and allocated to each of the pixels. Thus, the motion vector of each block is corrected to an accurate one of each of the pixels.
