Patent JP-H0654293-A (JP)
Title: Video signal processing device
Inventor: YAMAUCHI EIJI
IPC: H04N19/136
Filed: 1992-07-31
Abstract: PURPOSE:To improve the degradation of the picture quality by reducing the quantization error brought about in processes of quantization and inverse quantization used for video signal compression. CONSTITUTION:At the time of recording, 8X8 unit blocks subjected to DCT operation are quantized by first and second quantizers 55 and 57 and are compressed with a variable length code. At the time of reproducing, the signal decoded by a variable length decoder 62 is subjected to inverse operation of quantization by an inverse quantizer 63. Simultaneously, a quantization discriminator 64 determines whether correction is necessary or not in accordance with a quantization condition (class information, color information, quantization step Brn, and area information) supplied from the inverse quantizer 63 and outputs a control signal to a corrector 65. The corrector 65 performs correction by addition/subtraction of a certain value to/from the inversely quantized value based on this control signal. The output signal of the corrector 65 is subjected to IDCT operation and is outputted to an output terminal 68.

Title: Device for highly efficiently coding audio signal
Inventor: NAGAI KIYOTAKA
IPC: H03M7/30
Filed: 1992-07-31
Abstract: PURPOSE:To provide a compact audio signal highly efficiently coding device capable of reducing the operation quantity of a high pass filter(HPF) for remov ing unnecessary information less than the minimum audible frequency and attaining low power consumption and high compression efficiency. CONSTITUTION:A band dividing means 1 divides an audio signal into plural partial bands and outputs plural partial band signals. A thinning means 2 thins the partial band signals in each partial band and outputs thinned signals. The HPF 3 removes a low frequency component from the thinned signal in the minimum frequency partial band and outputs a high pass signal. An orthogonal transformation means 4 executes the orthogonal transformation of the high pass signal and the thinned signals and outputs transformation coefficients. A compression coding means 5 executes the compression coding of these transformation coefficients and outputs a coded signal. Consequently the audio signal highly efficiently coding device capable of reducing the quantity of operation and having high compression efficiency can be attained.

Abstract: PURPOSE:To prevent the breakdown of a laser diode when a supply voltage is varied, by detecting increase or reduction of the supply voltage and controlling a driving circuit of the laser diode in accordance with the detection result. CONSTITUTION:When the plus supply voltage rises, the base potential of a transistor TR Tr21 is raised, and the TR Tr21 is turned on when it exceeds +0.6V, and a TR Tr2 is turned off, and a laser diode LD is turned off. When the plus supply voltage falls, the base potential of the TR Tr2 is reduced, and the voltage between the base and the emitter of a TR Tr1 is reduced to reduce the output of the LD. When the minus supply voltage rises, the base potential of the TR Tr21 is raised, and the TR Tr21 is turned on when it exceeds +0.6V, and the TR Tr2 is turned off, and the LD is turned off. When the minus supply voltage falls, base and emitter potentials of a TR Tr3 are changed, and the voltage between the base and the emitter is not changed, and therefore, the output of the LD is not changed.

Title: Character display circuit
Inventor: KAWADA JUNICHI
IPC: H04N5/445
Filed: 1994-08-30
Abstract: PURPOSE: To clearly maintain the outline of a character, to reduce a cross color and to realize a visible display by adding a second edge signal having a second level between the level of a character signal and a first level between the character signal and a first edge signal. CONSTITUTION: An edge signal having two edge levels BK0 and BK1 is added between a background signal and the character signal in accordance with the two edge signals. The level of BK1 is set to the intermediate luminance level of B0 and a character level (white). In the video output of IC, the rise of BK 0→HARA and BK0→BK1→CHARA becomes slightly smooth by resistance quantity and additional capacity in IC and BK0→BK1→CHARA more smoothly rises compared to BK0→CHARA. Thus, the high frequency component of a luminance signal between an edge and the character becomes low compared to a conventional one. The luminance signal is prevented from being errorneously recognized as a chrominance signal and a cross color component can be suppressed.

Filed: 1993-07-27
Abstract: PURPOSE:To provide a small-sized and lightweight distance measuring device in which the distance can be easily measured even by one person by providing a rotating member connected to a rope body and rotated, and an arithmetic part for calculating the delivering quantity of the rope body on the basis of the data from a magnetic sensor. CONSTITUTION:Since a magnetic sensor 7 generates pulses in the ratio of one per rotation of a rotating member 5, a counter part 10 receives the pulse wave and counts the pulse number N. A calculating part 11 receives the rotating speed N of the rotating member 5 to determine the product of the circumference R of the rotating member 5 with the rotating speed N. Since the product of the circumference R with the rotating speed N is the sum of the quantity obtained by calculating 8 the delivering quantity of a rope body 2 and the rewind quantity, NXR is halved to calculate the actual walking distance. An output part 12 supplies the value of RXN/2 to a display part 3, and the display part 3 continuously displays the walking distance of a man. Thus, a walker can measure the distance while regularly confirming the walking distance.
