A method and apparatus for detecting and correcting motion artifacts in interlaced video signal converted for progressive video display. A correction is applied where interlaced video material is determined to originate from film source, thereby having been converted to video using a process known as 3-2 pulldown. Where the video material is not a result of the 3-2 pulldown process, a check is made for the presence of “pixel motion” so that corrections may be applied to smooth out the pixel motion. To determine 3-2 pulldown or field motion, a video field is compared to the field prior to the previous field to generate field error. Field errors are generated for five consecutive fields and a local minimum error repeated every five fields indicate the origination of the video material from film source using the 3-2 pulldown process. Upon confirmation of 3-2 pulldown, the video material is modified to correct for the mixing of two film frames into one interlaced video frame by assuring that the two fields of the de-interlaced video frame contain data from the same film frame. Where the video material did not originate from a film source, but pixel motion is detected, the pixel motion is smoothed out by an averaging method. The odd and even fields of the resulting video data are subsequently combined to form a progressive video material.

A fluorescent light flicker characteristic of an XY addressing type image pickup device such as a CMOS image pickup device is accurately detected and reliably and sufficiently reduced through a simple signal processing without using an photosensitive element regardless of the level of a video signal of a subject and the type of a fluorescent lamp.

The normalized difference value gn(y) is discrete Fourier transformed to extract a spectrum thereof, and a flicker coefficient Γn(y) is estimated from the extracted spectrum to calculate In′(x,y) / [1+Γn(y)].

Adaptive deinterlacing of interlaced video to generate a progressive frame on a per pixel basis. Two consecutive fields of interlaced video are converted into a frame of progressive video. One of the fields is replicated to generate half the lines in the progressive frame. Each of the pixels in the other half of the progressive frame are generated pixel-by-pixel. For a given output position of the pixel in the other half of the progressive frame, a correlation is estimated between the corresponding pixel in the non-replicated field and at least one vertically adjacent pixel of the replicated field, and optionally one or more vertically adjacent pixels in the non-replicated fields. Also, three consecutive input fields of interlaced video may be converted into two output fields of interlaced video on a per pixel basis taking into consideration differences in the consecutive input fields.
