Title: Leak integration average circuit and transmission line clock reproducing circuit
Inventor: SUZUKI NORIO
IPC: H04L25/40
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To simplify a circuit and to reduce circuit scale by constituting the average of an input signal by finding a differential signal, integrating this signal through an integration leakage circuit, finding an integrated value and subtracting it from a phase signal. SOLUTION: In a differential circuit 1, a register 11 outputs an input phase signal X while delaying it just for one clock cycle and a subtracter 12 inputs the input phase signal X and delay signal and inputs a difference E between both the signals to the integration leakage circuit 2. In the integration leak circuit 2, an adder 13 adds the leakage integrated value supplied from a register subtracter 14 and the differential signal E supplied from the differential circuit 1, finds an integrated value Y and supplies it to a subtracter 17. The register subtracter 14 subtracts the delayed integrated value supplied from a register 16 and a leakage value supplied from a leakage coefficient circuit 15 and outputs an integrated value from which the leakage value is subtracted.  The subtracter 17 subtracts the integrated value Y from the input signal X and a fluctuation (namely inclination) averaged phase signal Z is outputted.

IPC: H04N19/167
Filed: 1999-10-07
Abstract: PROBLEM TO BE SOLVED: To provide an image compressor that can reduce the size of data after compression enhancing the compression rate for the entire image than that of a conventional compression rate while minimizing deterioration in image quality due to compression. SOLUTION: The image compressor is provided with an image division section 1 that divides an image into two or more image areas, a frequency component detection section 2 that detects frequency components of each image area, a compression rate control section 3 that decides the compression rate in each image area on the basis of the result of frequency component detection, ad a image coding section 4 that applies wavelet transform coding to each image area with the compression rate decided by the compression rate control section 3. Thus the wavelet transform coding is applied to each image division area with the compression rate considered optimum depending on the frequency components of the area.  Since the image can be compressed with the wavelet transform coding with high compression rate to the image area where deterioration in the image quality is not remarkable and with a low compression rate to the image area where deterioration in the image quality is eminent, the compression rate for the entire image can be enhanced while minimizing the deterioration in the image quality due to compression.
