Title: Semiconductor memory
Inventor: TODA HARUKI
IPC: G11C11/401
Filed: 1992-11-30
Abstract: PURPOSE:To drive a word line in a short time by providing a plurality of memory cells, and selectively outputting a drive signal to a row decoder corresponding to any one set of memory blocks. CONSTITUTION:Memory blocks 31A, 31B respectively have a plurality of memory cells, and are divided into two sets.

Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To provide a preceding-vehicle recognition method in which a plurality of preceding vehicles can be recognized surely even when the plurality of preceding vehicles are imaged so as to be pverlapped. SOLUTION: In a laser radar, a laser beam is scanned in synchronizaiton with a synchronizing signal which is given to a camera (S1). Thereby, a distance up to an object in an image which is imaged by the camera can be grasped in units of pixels. The density histogram of the imaged image is created (S2), and a peak is extracted. The ratio Lav of a horizontal interpeak distance to a vertical interpeak distance is found, and whether the ratio Lav is within a tolerance ΔL or not is judged (S3). When the ratio is smaller than the tolerance ΔL, it is judged that a plurality of preceding vehicles are imaged so as to be overlapped, and distance data on a range surrounding the plurality of preceding vehicles is extracted in every pixel. On the basis of the distance data, the range is divided into ranges in which the respective preceding vehicles are contained respectively (S5).  Regarding the respective divided ranges, a vehicle recognition and processing operation is executed (S6).
