Title: Circuit and method for processing digital display signal
Inventor: MATSUDA SEIJI
IPC: G09G3/20
Filed: 2000-06-20
Abstract: PROBLEM TO BE SOLVED: To accurately perform asynchronous sampling to an input digital display signal. SOLUTION: A discriminant circuit 10 makes a comparison between undelayed sampling data obtained by sequentially latching the input digital display signal at the 1st edge of a PLL clock asynchronizing therewith and delayed sampling data obtained by sequentially latching at the 1st edge of an asynchronous clock by delaying the input digital display signal by a short period, and thereby discriminates whether both data coincide with each other.  As a result of the discrimination by this discriminant circuit 10, a selection circuit 30 selects and outputs the sampling data obtained by sequentially latching the input digital display signal at the 1st edge of the PLL clock for the period that the undelayed data coincide with the delayed data, and selects and outputs the sampling data obtained by sequentially latching the input digital display signal at the 2nd edge of the PLL clock for the period that the data do not coincide with each other.

Title: Method and apparatus for recognizing object, recording medium
Inventor: SAGAWA YOSHIE
IPC: G06T1/00
Filed: 2000-07-13
Abstract: PROBLEM TO BE SOLVED: To provide a technique whereby a vehicle running ahead can be appropriately recognized. SOLUTION: Although it is ideal to recognize the vehicle only on the basis of light receiving signals reflected by a reflector at a rear end of the vehicle, it may be considered that the signals are reflected by both the reflector having a relatively large reflecting intensity and a body structure having a relatively small reflecting intensity. If the object is recognized on the basis of all photo detection signals in this state, since data of a large light reception intensity gather to the closer side from one's vehicle and data of a small light reception intensity gather to the farther side, a breadth Aw and a depth Ad of the object A are recognized to be larger than actual values and a distance Az to the object is recognized to be longer than an actual value.  For solving the problem, only data of a relatively large signal intensity is extracted, so that the breadth Aw and the depth Ad of the object A or the distance Az to the object can be caught as values still closer to the actual values.

Title: Data processor
Inventor: SUGIOKA MIKIO
IPC: G01N21/27
Filed: 2000-07-25
Abstract: PROBLEM TO BE SOLVED: To provide a data processor capable of optionally reading not only processed data but original data and data in an intermediate process of a processing and with small required storage capacity. SOLUTION: Data acquired by an analyzer 1 is once stored in a storage device 2, is read, is performed with required arithmetic processing by an arithmetic unit 3 and is outputted by an output device 4. No processed data itself is stored and a tag to indicate the arithmetic processing performed when the processed data is obtained is added in a file of the original data instead. When the processed data is outputted again, it is reproduced by reading the original data and executing the arithmetic processing read from tag information to the original data. Since the data to be stored is only the original data, no storage capacity is wasted and the original data, the processed data or the data in the intermediate process of the processing are optionally outputted.
