摘要:
JPEG encoded data are entropy-decoded to quantized DCT coefficients which are sent to a prediction tap extraction circuit (41) and to a class tap extraction circuit (42). The prediction tap extraction circuit (41) and the class tap extraction circuit (42) extract what is needed from the quantized DCT coefficients to form prediction taps and class taps. A classification circuit (43) effects classification based on the class taps. A coefficient table storage unit (44) sends tap coefficients corresponding to the classes resulting from the classification to a sum of products circuit (45), which sum of products circuit (45) then effects linear predictive calculations, using the tap coefficients and the class taps, to generate decoded picture data.

摘要:
In an image signal converting method and an image signal converting apparatus, it is possible to perform a proper classification considering various signal characteristics of input image data and convert low-resolution input image data to high-resolution image data by using not only a classifying means 56 for classifying input images in accordance with the level distribution pattern of the input images but also a classifying means 50 for classifying input images in accordance with the movement of the input images and deciding the final class D32 of input image signals by both CLASS0 and CLASS1 obtained by both classifying means 50 and 56.
摘要:
An input digital image signal (SD signal) is converted into a high resolution digital video signal (HD signal). A considered pixel is categorized as a class corresponding to a one-dimensional, two-dimensional, or three-dimensional level distribution of a plurality of reference pixels of the SD signal. A predicted value of the considered pixel is generated by linear combination of values of a plurality of pixels of the SD signal adjacent to the considered pixel of the HD signal and predicted coefficients that have been learnt. In the learning process, predicted coefficients are determined by linear combination of the values of pixels of the SD signal and the predicted coefficients so that the sum of squares of the predicted value and the true value is minimized. Instead of the predicted coefficients, representative values may be determined for each class. In this case, the representative values are used as predicted values corresponding to the class of the input SD signal. Examples of the representative values are a base value of a block and a value normalized by dynamic range DR.

In an apparatus for judging a hand movement of an image, pixels where absolute values of differences between image data of respective pixels of blocks of a current frame and image data of representative point pixels of blocks of an earlier frame read out from a representative point memory satisfy a predetermined condition are judged by a condition judgment circuit to form a frequency distribution table corresponding to the judged result by a frequency distribution table formation circuit to calculate, on the basis of the frequency distribution table, the number of coordinates having a frequency value greater than a predetermined value in the vicinity of a coordinate designated by a motion vector of an image to judge the motion vector to result from a hand movement when the calculated value is less than a predetermined value.
