摘要： A radar signal processor is disclosed having an observation mechanism for receiving a reflected wave from a target and for outputting a predetermined observation signal. The processor extracts a distance component corresponding to a distance from each observation signal. The processor further collects the respective distance components and computes an estimated value of a corresponding correlation matrix with a forgetting factor as a parameter using a method for estimating correlation matrix with exponential smoothing. The processor further estimates the presence or movement state of the target on the basis of the respective estimated values of the correlation matrices and outputs the computed values.

摘要： In a system, a detecting module cyclically detects positional information of reflection points of received echoes. A sampling module cyclically samples, from the detected reflection points for each cycle, first and second reflection points. The first and second reflection points are expected to be reflection points of the respective first and second reflective portions of a moving object in front of the system. A first determining module determines whether a distance between the first and second reflection points varies over time. A second determining module determines that the first and second reflection points correspond to reflection points of the respective first and second reflective portions of a single moving object when it is determined that the distance between the first reflection point and the second reflection point is substantially invariant over time.

摘要： An image processing apparatus extracts a contour pixel of a binary input image signal in a contour pixel extraction portion, and calculates a line thinning amount from the extracted contour pixel based on a preset parameter in a line thinning amount calculation portion. The apparatus judges whether black pixel areas of the binary input image signal are connected in a finite area including a target pixel in a finite area connectivity judgment portion. The apparatus adds a line thinning amount to the binary input image signal of the target pixel in accordance with the judgment by the finite area connectivity judgment portion and outputs obtained results in a selective correction output portion.

摘要： In an image processing apparatus, such as a digital color/monochromatic copying machine, for reading a color image or a monochromatic image and producing a copy image thereof, an image process section is composed of an arithmetic section which is programmed and operated by software, or image process programs. The image process programs are input from outside via an external interface and loaded in an external RAM. On the basis of input information from an operation panel, an optimal image process program is read out of the external RAM and loaded in an instruction RAM. The arithmetic section executes the image process program in the instruction RAM.
