Title: Monitoring method for vehicle
Inventor: NAKAJIMA MASATO
IPC: B60W30/00
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To recognize optical flow quickly by setting a narrow long window as to an aimed single point, which corresponds to a point indicating the photographing direction from a driver's own vehicle, in the radial direction from an infinite point and performing calculation only within the range of this window in the previous image among two frames of images. SOLUTION: An optical flow (velocity vector) appears radially from one point called as FOE (an infinite point or a sublimation point) in an image. The FOE corresponds to a single point indicating the photographing direction which is also the advancing direction of a driver's own vehicle on the image. Firstly, to an aimed single point P in an image at a time (t), a narrow long window is set from the FOE. Secondly, in the image at a time (t+Δt), the sum of absolute values of the luminance difference between luminance in the window at a time (t) and that in the window at a time (t+Δt) is found while the window is shifted one point by one point in the radial direction from the FOE. Then, a shift quantity of the window when the sum is minimized is found as a velocity vector PQ of the aimed simple point P.

Title: Analog signal processing system for bar code reader
Inventor: SATO SHINICHI
IPC: G06K7/00
Filed: 1989-09-20
Abstract: PURPOSE:To set a slice level high at a part where no bar code exists by level- changing a level variable type slice level generating means by the output of a pattern deciding means. CONSTITUTION:When a sensor 11 starts to read the bar code 8, the pattern deciding means 17 discriminates the read of the bar code from the output of a pulse signal generating means 16, and outputs a signal to the level variable type slice level generating means 14, and controls it so as to lower a slice level the slice level generating means 14 generates, and makes the reading sensitivity of the bar code high. Besides, when the part where no bar code exists or the part where a white margin is long is read, the pattern deciding means 17 does not output the signal to the slice level generating means 14, and keeps the slice level the slice level generating means 14 generates a little higher, and reduces the influence of a white level noise. Thus, when the start code of the bar code is recognized, the slice level can be set low, and at the part where no bar code exists, the slice level can be set high.
