Abstract: PROBLEM TO BE SOLVED: To provide a detecting signal processing circuit for a common rail pressure to detect a fuel injection timing and a fuel injection amount at a low cost with high-precision by effecting analogue processing of a detecting signal for a common rail pressure without being directly digitalized and analogue- processed.

Title: Television receiver
Inventor: SATO KOICHI
IPC: H04N5/44
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To reduce image quality deterioration due to distortion caused at the time decoding by subtracting an output from which horizontal and vertical components in a high pass component in a time direction are separated from an output that receives encoded image data and decodes it. SOLUTION: A decode processing circuit 1 inputs decoded image data, performs MPEG decode processing and outputs base band signals (Y, CR and CB). A decoded base band signal is inputted to frame memory 3 and is delayed by one frame period. A subtracter 7 subtracts an output signal of the memory 3 from the decoded base band signal and outputs a high pass component in a time direction. As for the high pass component, a high pass filter (HV HPF) 9 for horizontal and vertical components separates a high pass component. A subtracter 3 extracts only a distortion component by subtracting the separated high pass component from the decoded base band signal and eliminates it. This reduces distortion where an image edge part sways and block distortion.

Title: Multi-value image data transmission method
Inventor: OOMORI MASATAKE
IPC: H04N19/85
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To send an image with a high image quality even when a coding compression rate is high and a transmission data quantity is small by sending code data of each bit plane of a high-order bit group and code data of each bit plane of a low-order bit group altogether as one set of multi-value image data.

Then a coding decoding circuit 7 applies coding compression to the multi- value data and decodes the multi-value image data subjected to coding compression into original multi-value image data. Then the image of high-order 3-bit in 8-bit original image data is subjected to bit plane coding directly and least significant bit data of the low-order 5-bit data are aborted. Then the remaining other 4-bit data are subjected to dither binarization processing and the obtained low-order bit plane data are used for one bit plane, then a high image quality image is sent even when the coding compression rate is high and the transmission data quantity is small.
