Apparatus for judging the order of arrival of racers at a goal in a race and the time taken for the race, having a plurality of line sensor cameras
First Claim
1. An apparatus for judging the order of arrival of racers at a judging criterion line in a race and time taken for the race, said apparatus comprising:
- at least two line sensor cameras disposed opposite to each other over said judging criterion line so as to pick up images of moving objects passing through said judging criterion line;
a memory unit for storing respective video signals supplied from said respective line sensor cameras successively in time series;
an operating unit for specifying ranges of said respective video signals to be stored in said memory unit and specifying ranges of signals to be read out of said respective video signals stored in said memory unit;
readout means for effecting scan conversion on all or a part of video signals specified by said operating unit out of said respective video signals stored in said memory unit and reading out resultant video signals; and
video monitor means for simultaneously displaying said respective video signals from said respective line sensor cameras read out by said readout means.

Abstract
Apparatus for judging the order of arrival of racers at a goal in a race and the time taken for the race, capable of storing, in a memory unit, video signals of a plurality of line sensor cameras disposed so as to be able to pick up images of moving objects from both directions with a judging criterion line between or from such angles that moving objects do not overlap, effecting scan conversion on the stored video signals of the plurality of line sensor cameras, reading resultant video signals, and displaying video signals thus read out respectively singly or simultaneously plurally on a single video monitor.

11. An apparatus for judging the order of arrival of racers at a judging criterion line in a race and time taken for the race, said apparatus comprising:
-
two line sensor cameras disposed opposite each other over said judging criterion line so as to pick up images of moving objects passing through said judging criterion line in mutually different scanning regions from both directions with said judging criterion line; a memory unit for combining two video signals supplied from said two line sensor cameras so as to be housed in the scanning regions and storing the combined video signals respectively successively in a time series; an operating unit for specifying ranges of said video signals to be stored in said memory unit and specifying ranges of signals to be read out of said video signals stored in said memory unit; readout means for effecting scan conversion on said combined video signals existing in the ranges specified by said operating unit out of said combined video signals stored in said memory unit and reading out resultant combined video signals; and a video monitor for displaying the combined video signals read out by said readout means. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. An apparatus for judging the order of arrival of racers at a judging criterion line in a race and time taken for the race, said apparatus comprising:
-
at least two line sensor cameras disposed opposite to each other over said judging criterion line so as to pick up images of moving objects passing over said judging criterion line, each of said at least two line sensor cameras being disposed at about a same distance from at least a predetermined portion of said judging criterion line; a memory unit for storing respective video signals supplied from said respective line sensor cameras successively in time series; an operating unit for specifying ranges of said respective video signals to be stored in said memory unit and specifying ranges of signals to be read out of said respective video signals stored in said memory unit; readout means for effecting scan conversion on all or a part of video signals specified by said operating unit out of said respective video signals stored in said memory unit and reading out resultant video signals; and video monitor means for simultaneously displaying said respective video signals from said respective line sensor cameras read out by said readout means.
