PURPOSE:To read accurately the racing numbers with no human mistake and to secure automatically the correspondence between racers and the race time to attain the accurate counting of the race time, by using at least >=2 pairs of optical systems and image sensors. CONSTITUTION:The optical image of an object 201 like a racer, etc. is formed on the photoelectric screens of image sensors 203 and 205 with different angles by optical systems 202 and 204. The optical image information on the photoelectric screens are converted into video signals and sent to signal processing parts 206 and 207 of the next stage. These video signals undergo various types of processes and sent to a discriminating part 208 of the next stage. The part 208 recognizes numeric characters from each signal according to the basic information on the standard character and by means of various recognition methods. The accurate recognition of characters is performed for each result of recognition through various conditions including a comparison for coincidence or dissidence. While digital signals are sent to a time counting device 210 in response to the start and goal signals to secure the correspondence to the race time.
