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： Decoders A and B decode MPEG-2 bitstreams A and B. A switch (S1) switches from decoded stream A to decoded stream B to achieve a splice. The resulting bitstream is re-encoded in an encoder 4. A new GOP is defined beginning at the splice. The new GOP is defined by picture type decision rules which may the effect of changing the GOP compared to the GOPs of streams A and B. The new GOP provides a prediction of the position in stream B where the occupancy value of stream C should coincide with that of B. A target for the new number of bits in the new GOP is calculated dependent on the difference between the occupancy value of stream C at the splice and a prediction of the occupancy of stream B at the predicted position. The occupancy value of stream C is controlled in accordance with the target so that it tends towards the occupancy value of stream B at the predicted position.

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.

摘要： An image processing apparatus generating output pixel values with respect to pixels of an input image selected in accordance with an image feature direction in the input image and including a comparing mechanism comparing blocks of pixels of the input image, the blocks disposed with respect to a pixel position under test so that a correlation between the blocks would indicate an image feature direction applicable to that pixel position; and a validating mechanism detecting whether an image feature direction may be used to interpolate an output pixel value at the pixel position under test. The validating mechanism: (i) detects whether a detected image feature direction for the pixel position under test meets one or more predetermined directional criteria; and (ii) detects whether pixel values in image regions disposed with respect to the pixel position under test in accordance with possible image feature directions meet one or more predetermined pixel value criteria.

摘要： Data compression apparatus for compressing an input data unit to produce an output data unit in accordance with a desired data quantity of the output data unit, the degree of compression being determined by a compression control variable having a range of possible values. A trial encoder compresses successive sections of the input data unit in accordance with a trial group of two or more values of the compression control variable. A data quantity detector detects the trial data quantities generated by each trial encoding of the sections of the input data unit and selects a base compression control variable applicable to the input data unit on the basis of the detected trial data quantities, in order to comply with the desired data quantity. An allocator allocates a compression control variable for use in final encoding each section of the input data unit to generate the output data unit, the allocator being comparable to determine whether to use the base compression control variable or another possible value of the compression control variable for the current section.
