ABSTRACT:
There is provided an image signal deinterlacing apparatus for converting an interlaced scanning image into a progressive scanning image. The deinterlacing apparatus includes: an intra-field pixel processing unit for detecting a face area and a to-be-interpolated data within a field by using pixels of a field disposed before two field from a current field; a motion value generating unit for detecting first to third motion values and first and second motion degree values; a history control unit for detecting a history value; a fast image processing unit for detecting a fast motion image; a film image processing unit for detecting a film image and a caption area and determining a to-be-interpolated field data; a still image processing unit for accumulating the first motion value and the second motion degree value to detect a still image; an inter-field noise image processing unit for detecting an adjacent inter-field noise image; a motion boundary maintenance image processing unit for detecting a motion boundary maintenance image; and a synthesizing unit for selectively interpolating the intra-field to-be-interpolated data, the before-one-field inter-field data and the before-three-field inter-field data according to the detection result.
