Title: Determination unit for delivery route
Inventor: OHATA KOICHI
IPC: G06F19/00
Filed: 1991-04-17
Abstract: PURPOSE:To solve the most efficient traveling delivery sequence, which is an extended traveling salesman problem, when arrival time from a destination is specified with a time range. CONSTITUTION:A program computer is used to set the first traveling destination temporarily to solve a traveling salesman problem. Then, if there is a solution available, it is stored as a temporary solution. This operation is repeated while sequentially changing the first traveling destination. Temporary solutions that were stored after all traveling destinations were set as the first traveling destination are estimated. In such process, a branch table is generated for setting a traveling sequence. When there is no solution for the branch table, or a solution that is found is not better than the preceding solution, the following search is halted to reduce the number of times of calculation, thereby being able to execute a rational operation for a traveling delivery procedure within a very short period of time. The rational calculation can be done within a short period of time before a vehicle starts, thereby trying to reduce the vehicle traveling cost.

Abstract: PROBLEM TO BE SOLVED: To provide an image processor in which reading accuracy of an image is improved through the elimination of a redundant component included in a reflected light of an original by providing a means to correct a read error caused in a thin line area in a white background mainly due to scattering of a light irradiating the original. SOLUTION: This processor is provided with a read error correction section consisting of a thin line area detection section 21, a line width detection section 22 and athin line density conversion section 23, and the correction section converts image signals R, G, B subjected to shading correction and logarithmic correction into R', G', B' and output them to a next stage. The thin line area selection section 21 and the line width detection section 22 detect the image signal G as to whether or not the signal is in existence in a thin line area or detect the line width. The thin line density conversion section 23 decides the correction amount depending on the density and the line width of the thin line area in the case of the thin line area based on the detection result and corrects and output the image signals R, G, B.  When not in the thin line area, the section 23 outputs the image signals R, G, B as they are. Thus, the image processor is obtained, in which image read accuracy is improved.
