Title:
【発明の名称】レース時間計測装置
Document Type and Number:
Japanese Patent JP3182691
Kind Code:
B2
Abstract:
The racing time-keeping apparatus of the video-finish type comprises a CCD photosensitive array (5) which can be read at a specified frequency corresponding to the rate of advance (VI) of the picture of the race.
The pictures are recorded and displayed by means of a recorder (22) and a monitor (23), commercially available, at a fixed, standardised scanning frequency. Since the frequency of picture capturing by the array is not synchronous with the display frequency, generation of picture segments is undertaken using buffer memories (19, 20), the picture segments next being stored in a picture memory (21) and then read in discontinuous fashion by skipping picture segments in synchronism with a standard TV scanning.
The apparatus makes it possible to offer a system at low cost price since it uses a recorder and a monitor which are currently available on the market.
