摘要： A judder detection apparatus, a de-interlacing apparatus using the judder detection apparatus, and a de-interlacing method. The judder detection apparatus includes a judder detector to detect whether a detected pattern that is similar to a judder pattern occurs using predetermined pixel values of even and odd fields sequentially input, a pattern detector to detect whether an input image has a uniform pixel value in every other line of the even and odd fields and whether consecutive lines of the even and odd fields have a blind pattern having a difference from the uniform pixel that is greater than or equal to a threshold value, and a determiner to determine whether the detected pattern that is similar to the judder pattern is a judder based on whether the blind pattern is detected.

摘要： Disclosed herein is a method to detect and identify 3-2 pulldown patterns in a video sequence. If no 3-2 pulldown pattern is detected, the video remains unmodified. If 3-2 pulldown patterns are found, repeated fields are removed and original frames are reconstructed. Optionally, additional instructions may be generated for a video encoder. Additionally, in accordance with the present invention, repeated fields are removed in a way that does not throw away any information. The method described herein describes a plurality of operations that define one or more metrics or parameters of the video data for use in identifying the repeated fields.

摘要： Methods and systems for determining fields in a video signal are disclosed. Historic field ID values for a received video signal may be stored and subsequently utilized by a summer and/or a correlator in order to estimate a field ID value for a current field. The summer may sum all historic field ID values and, if the sum is within a determined range, for example, the field ID value for a current field may be estimated based on the sum of the historic field ID values. If the sum is not within the determined range, for example, the historic field ID values may be correlated with an expected field ID value or with an inverted expected field ID value. The correlation may then be utilized to estimate the field ID value for the current field.

摘要： A television line doubler (interlaced to progressive scan converter) incorporating the following aspects—an improved field motion detector which does not treat low frequency vertical transitions as motion; a frame motion detector having an improved ability to differentiate motion from subcarrier signal components; a sawtooth artifact detector; a sawtooth artifact detector in combination with a film pattern detector, such that the artifact detector can take the film pattern detector out of film mode earlier than it would if it only were responsive to a break in the film pattern; tandem field motion detectors; an improved field based film detector; film pattern detectors and motion detectors used therewith which operate by performing end-of-field calculations; the combination of a field motion detector and a frame motion detector such that the frame motion detector provides a motion signal used as a verification by the field motion detector; an improved NTSC film detector requiring a minimum number of NTSC film pattern sequences; and an improved PAL film detector employing a minimum motion threshold detector.

摘要： A pattern analyzing portion analyzes a pattern of a detected repeat field and determines whether or not the pattern of the repeat field is continuous. An inverse pull-down controlling portion controls a memory to read video data in such a manner that the repeat field detected by a comparator is removed from input video data in a period that the pattern of the repeat field is continuous. The inverse pull-down controlling portion controls the memory to read video data in such a manner that a repeat field detected by the comparator is not removed from the input video data in a period that the pattern of the repeat field is discontinuous. In other words, an inverse 2:3 pull-down process is controlled corresponding to the continuity of a pattern of a repeat field. In addition, it is determined whether an input original material is a progressive-scanned video material or an interlace-scanned video material corresponding to the continuity of the pattern of the repetitive material.

摘要： Methods and systems for compressing video content are presented. The methods and systems include analyzing a sequence of media frames stored in the memory device and calculating a displacement level of each of the media frames. The displacement level indicates how different each of the media frames is to a previous media frame. The sequence of media frames is divided into a plurality of cuts where each cut ends at a media frame having a substantially high displacement level. Frames to be removed from the sequence of media frames are identified in each cut based upon the frame's displacement level. The identified frames are then removed.

摘要： Some embodiments of the invention provide a media-editing application that performs frame rate conversion detection on a video. For a video that has been converted from one frame rate and format to another frame rate and format, the application detects the conversion method that has been used in the conversion of the video. Some embodiments perform this frame rate conversion detection by detecting patterns of repeating fields and/or frames in a video sequence created by the different conversion processes.Some embodiments compute (i) a frame difference value for each consecutive frames, (ii) a correlation score for the first and second fields of each frame, and (iii) a correlation score for the second field of each frame and the first field of a succeeding frame. Frame difference values are compared with each other to detect repeated frames and correlation scores are compared with each other to detect repeated fields.
