IPC: H04N7/24
Filed: 1991-06-11
Granted: 1998-04-27
Abstract: Disclosed is a method to select data for compressing an d transmitting image signal.  The method comprises steps of signal inputting(S101), data selecting(S102), storing(S103), data detecting(S104), defining(L1) and frame controlling(S106).  In the signal inputting step(S101), an image data of 3 order transform is acquired by LOT(Lapped Orthogonal Transform) and DCT(Discrete Cosine Transform).  In the data selecting step(S102), data whose value is higher than a limit value are selected from the transformed data.  In the storing step(S103), the selected data is temporarily stored for output.  In the data detecting step(S104), the output data stored is detected.  In the defining step(L1), the detected data is compared with a goal data by a defining function.  In the frame controlling step(S106), the threshold values on the signal inputting step(S101) for next frame are varied if the detected data is not accorded with the goal data.

Title: Luminance and chroma signal separation system
Inventor: BANG JUN-WON

Filed: 1991-07-26
Granted: 1994-02-23
Abstract: The system comprises frame and line comb filters for outputting frame and line difference signals of the video signal respectively. A first filter extracts a chrominance signal from the video signal, and a line correlation detector senses the line correlations with respect to the line difference signals. A chrominance signal level senses a level of the output of the first filter. A moving level detector senses a moving level of the video signal based on the frame difference signal. A first operator governs the output of the switch and the moving factor, and a second operator controls the output of the frame comb filter and a value. An adder sums the outputs of the two operators, and a second filter filters the output of the adder to extract a chrominance signal. A third filter filters the output of the adder to output the final chrominance signal.

Abstract: The out sole of the shoe heel, where is the fastest part being deformed by the body weight and working stance, can be utilized more time by changing it with that of the other shoe. The uppers of the leather shoe on the shoe body is bonded with insole, the out sole is bonded with the lower side of the middle sole for the changeable shoe sole.
