摘要： A method of image processing for conversion of an image in a sequence of images comprises the steps of associating pixels of an image with respective motion values indicative of a degree of inter-image motion for each pixel; adjusting the motion value of each pixel based upon the motion value of a secondary pixel found within a first region of a first predetermined size substantially centered upon each respective pixel, said secondary pixel being that whose associated motion value is indicative of the greatest motion of any pixel in the first region; adjusting the motion value of each pixel based upon the motion value of a secondary pixel that lies within a second region of a second predetermined size substantially centered upon each respective pixel, said secondary pixel being that whose associated motion value is indicative of the least motion of any pixel in the second region; categorizing each pixel as a static pixel or a motion pixel according to its respective associated motion value, and then selecting respectively either a first conversion process or a second conversion process for a pixel dependant upon whether that pixel is categorized as a static pixel or a motion pixel.

摘要： An image processing apparatus includes a first motion detector, a second motion detector and a conversion selector. The first motion detector detects motion to a first level of spatial frequency sensitivity. The second motion detector detects motion to a second level of spatial frequency sensitivity greater than the first level of spatial frequency sensitivity to detect smaller amounts of motion than the first motion detector. The conversion selector selects contributions from at least one of a first conversion process and a second conversion process for a given point in an image dependant upon whether motion is detected by the first motion detector at the given point or not. The conversion selector operates independently of the second motion detector if a degree of motion within the image or a part thereof including the given point detected by the first motion detector does not exceed a threshold amount.

摘要： A method of image processing for converting interlaced images to progressive scan images comprises the steps of generating a motion dependent mixing value for determining the extent to which a preceding image field should be mixed with a current intra-field interpolated image field at a given pixel position, comparing the generated mixing value with a preceding historical mixing value, and if the comparison indicates an increase in motion, using the generated mixing value; otherwise, if the comparison indicates a decrease in motion, temporally filtering the generated mixing value prior to use.

摘要： An image processing method for image conversion by combining two or more source values based on a mixing parameter to generate an output pixel value. A metric is calculated for a selected pixel at a given image field based on the directly preceding image field and a spatially interpolated version of the given image field at the selected pixel position. The selected pixel is categorized based on the metric as providing an indeterminate, unreliable, or reliable basis for a determination of motion at that pixel. The mixing parameter for the selected pixel is adjusted based on the categorization of the pixel.
