Method and apparatus for an adaptive deinterlacing on the basis of a phase corrected field and recording medium the programs for the execution of the adaptive deinterlacing method stores

摘要

There is disclosed an adaptive de-interlacing method and apparatus based on a phase corrected field of an input interlaced picture signal, and a recording medium storing computer programs for executing the method. The method includes: generating a phase corrected kSUPth /SUPfield by compensating a phase of the kSUPth /SUPfield of the input interlaced picture signal by 1 line frequency; calculating a first motion vector between the phase corrected kSUPth /SUPfield and the (k-1)SUPth /SUPfield of the interlaced picture signal; calculating a second motion vector between the (k-1)SUPth /SUPfield and the (k+1)SUPth /SUPfield of the interlaced picture signal; and determining whether there is motion of the input picture based on the first and second motion vector values, and generating a kSUPth /SUPprogressive frame based on the result and the kSUPth /SUPfield. Thus, a serration phenomenon is minimized after de-interlacing by more exactly detecting the motion information of a corresponding inserted field.
