摘要： Correlation of videos between fields is determined between a difference between an input interlaced signal and a signal that is delayed by one field with respect to the input interlaced signal. Correlation among N-1 sequential fields is compared with a predetermined pattern to determine whether the input interlaced signal is unquestionably a telecine-converted signal, whether it is unquestionably not a telecine-converted signal, or whether it cannot be said to be unquestionably a telecine-converted signal. If a determination of being unquestionably a telecine-converted signal is continued for a predetermined number or more of fields, an instruction signal, which instructs to perform inter-field interpolation on the input interlaced signal, is outputted.

摘要： A method and apparatus for low-delay conversion of 3:2 pulldown video to progressive format with field averaging is disclosed. The method considers 3:2 pulldown interlaced video that represents a four-frame motion picture film sequence as a ten-field interlaced video field sequence of three, two, three, two video fields per motion picture frame respectively for the four-frame sequence. One step of the method is the step of creating a ten-frame progressive video frame sequence, having a delay of approximately one field time with respect to the ten-field interlaced video sequence. This step is achieved by combining at one field time intervals a top field and a bottom field from the ten-field interlaced video sequence, where, at the time of combination, the top field and the bottom field are the most recently available top and bottom fields corresponding to the same motion picture film frame. The method comprises the further step of substituting, for the top field or the bottom field in the combining step, an average of that top or bottom field and the field two fields prior, when that top or bottom field and the field two fields prior correspond to the same motion picture film frame. Apparatus for performing the above method includes a multiplexer that accepts an input video signal, a two-field-time delayed signal, and a signal that represents the average of these two. The multiplexer outputs a send field and a store field that meet the criteria described above. The send field and a one-field-time delayed version of the store field are combined to produce a progressive frame.

摘要： Jagged vertical or diagonal transition artifacts in interlaced to line doubled progressive scan converted television signals are detected and areas of the television picture having such artifacts are subjected to vertical averaging such that the resolution of the jagged transitions is reduced, thereby softening, "greying" or "fuzzing" the jagged transitions and causing them to appear smooth. Thus, highly contrasted lines appearing in a sawtooth pattern, which are extremely perceptible, are replaced with a flash of what might be characterized as "fuzziness," which is not perceptible. The eye no longer perceives the jagged artifacts. Moreover, areas of reduced vertical and horizontal resolution, resulting from the vertical averaging, do not create any new artifacts and are not perceived by the eye. Artifacts are detected by comparing pixels in corresponding positions in the scan lines of the line doubled progressively scanned television signal. The detection scheme looks for sawtooth patterns by determining if there are differences among pixels in more than one set of three adjacent lines. When a sawtooth pattern is detected, the uncorrected signal in the sawtooth region of a scan line is faded to a vertically filtered or averaged signal just prior to the onset of the sawtooth artifact region and then faded back to the uncorrected signal just subsequent to the sawtooth artifact region. The sawtooth correction signal, which controls fading to and from a filtered video signal, is expanded in all directions horizontally and vertically somewhat beyond the region of the detected artifact in order to insure that all of the artifact is suppressed.
摘要翻译：检测到隔行扫描到逐行扫描转换的电视信号的锯齿状垂直或对角线过渡假象，并且对具有这种假象的电视图像的区域进行垂直平均，使得锯齿形转变的分辨率减小，从而软化“变灰”或 “模糊”锯齿状的过渡，使他们看起来顺利。因此，出现在锯齿形图案中的极其可见的高度对比线被被称为“模糊性”的闪光所替代，这是不可察觉的。眼睛不再察觉到锯齿状的文物。此外，由垂直平均所导致的垂直和水平分辨率降低的区域不会产生任何新的伪影，并且不被眼睛感知。通过比较行倍增逐行扫描的电视信号的扫描线中的相应位置的像素来检测伪像。检测方案通过确定多于三组相邻行中的像素之间是否存在差异来寻找锯齿形图案。当检测到锯齿形图案时，扫描线的锯齿区域中未校正的信号刚好在锯齿伪影区域开始之前衰减到垂直滤波或平均的信号，然后在锯齿波之后退回到未校正的信号神器区域。控制衰落到滤波视频信号的滤波器的锯齿波校正信号在水平和垂直方向的所有方向上被扩展到稍微超过检测到的伪影的区域，以确保所有的伪影被抑制。

摘要： A method of and apparatus for displaying an image clip comprising a plurality of image frames on an electronic monitor includes separating each image frame from the next image frame by an overscan period. In this way image frames captured at a first frame rate can be displayed at the first frame rate on a monitor arranged normally to display images at a second frame rate, different to the first frame rate. In practice, the overscan period is created by adjusting driving circuitry for the monitor to increase the number of lines of data output to the monitor during a frame or field period whilst maintaining the line rate constant.

摘要： An input digital video signal representing a series of input frames is processed to produce an output digital video signal representing a series of output frames with an increased motion blur effect. For each output frame at least one intermediate field or frame is produced by motion compensated temporal interpolation between a pair of the input frames. Each output frame is then produced by combining the intermediate field or frame with at least one further intermediate field or frame and/or with one of the respective input frames so that the output frame has an increased motion blur characteristic compared with that of the input frames. Using motion compensated temporal interpolation, a change in frame rate can also be produced as between the input frames and the output frames.

摘要： A video image alteration apparatus is described that separates the vertical and horizontal aspects of image alteration. Pixels relating to an input image derived from a frame of film are sampled at a predetermined rate related to a film scanning speed and a television line standard, and the flow of pixel information is coordinated through a memory section by write control and read control signals. A frame store, which stores image pixel data corresponding to at least one film frame, includes a line output and address inputs for selecting a line start position and a line advance increment. To obtain the aforementioned spatial separation, a line store, which is responsive to the line output of the frame store for storing at least one line of image pixel data, includes a pixel output and address inputs for selecting a pixel start position and a pixel advance increment. Lines and pixels are repeated as necessary for zoom and pan effects by appropriately addressing the frame store for vertical repeats and the line store for horizontal repeats. New image pixels are then generated by a spatial interpolator responsive to the pixel output of the line store.
