Utazzunk vissza az id\u0151ben 2017 egyik legforr\u00f3bb j\u00faliusi napj\u00e1ra, amikor a Tour de France 7. szakasza zajlott. N\u00e9gy ker\u00e9kp\u00e1ros volt sz\u00f6k\u00e9sben, de m\u00e9g 6 kilom\u00e9ter h\u00e1tra volt a versenyb\u0151l. A Nuits-Saint-Georges fel\u00e9 sz\u00e1guldva \u00e9lvezt\u00e9k a menetsz\u00e9l h\u0171v\u00f6s simogat\u00e1s\u00e1t, amikor az utols\u00f3 200 m\u00e9teres szakaszra \u00e9rve \u00fagy l\u00e1tszott, hogy a norv\u00e9g versenyz\u0151 fog nyerni. Azonban hirtelen az \u00e9lre t\u00f6rt a n\u00e9met Marcel Kittel \u00e9s l\u00e1tsz\u00f3lag pontosan egyszerre szelt\u00e9k \u00e1t a c\u00e9lvonalat.<\/p>\n

Az abszol\u00fat holtverseny l\u00e1tszata ellen\u00e9re a Tissot \u00f3ragy\u00e1rt\u00f3 c\u00e9g, aki az id\u0151m\u00e9r\u00e9s\u00e9rt volt felel\u0151s, Kittel gy\u0151zelm\u00e9t hirdette ki: 0,0003 m\u00e1sodperccel \u00e9rt hamarabb c\u00e9lba a n\u00e9met versenyz\u0151, mind\u00f6ssze 6 millim\u00e9terrel hagyva le ellenfel\u00e9t. Ha a verseny n\u00e9h\u00e1ny \u00e9vtizeddel ezel\u0151tt zajlott volna le, akkor val\u00f3sz\u00edn\u0171leg egy 1 km-es d\u00f6nt\u0151ben kellett volna megk\u00fczdeni\u00fck a gy\u0151zelem\u00e9rt. 2017-ben azonban m\u00e1r olyan kamer\u00e1kat haszn\u00e1lt a Tour, amik k\u00e9pesek voltak m\u00e1sodpercenk\u00e9nt 10000 k\u00e9pkocka k\u00e9sz\u00edt\u00e9s\u00e9re, \u00edgy Marcel Kittel \u00fcnnepelhetett aznap.<\/p>\n

A c\u00e9lfot\u00f3 tal\u00e1lm\u00e1ny\u00e1t a l\u00f3versenyek nehezen meghat\u00e1rozhat\u00f3 be\u00e9rkez\u00e9si sorrendj\u00e9nek k\u00f6sz\u00f6nhetj\u00fck.

Azonban ez sokszor csak millim\u00e9ternyi k\u00fcl\u00f6nbs\u00e9geket jelentett, szabad szemmel szinte lehetetlen volt meghat\u00e1rozni, ki lett a gy\u0151ztes. A l\u00f3versenyeken m\u00e1rpedig sok p\u00e9nz forgott kock\u00e1n, nem lehetett bizonytalan az eredm\u00e9ny.<\/p>\n

A legr\u00e9gebbi fennmaradt c\u00e9lfot\u00f3t John Charles Hemment k\u00e9sz\u00edtette 1890-ben. A kamer\u00e1t a c\u00e9l vonal\u00e1ban helyezt\u00e9k el, az expon\u00e1l\u00e1st pedig az els\u0151 l\u00f3 ind\u00edtotta el, azzal, hogy elszak\u00edtotta a p\u00e1ly\u00e1n v\u00e9gigvezetett fonalat. Mivel a kamera egyetlen k\u00e9pet tudott l\u0151ni, a m\u00f3dszer gyakran vallott kudarcot, de j\u00f3 kiindul\u00e1si alapnak bizonyult. 1920 \u00f3ta mozg\u00f3k\u00e9pkamer\u00e1kat haszn\u00e1ltak, ezek azonban t\u00fal alacsony sebess\u00e9ggel rendelkeztek ahhoz, hogy val\u00f3ban seg\u00edts\u00e9k a d\u00f6nt\u00e9st. A Paramount Pictures mozg\u00f3k\u00e9p-m\u00e9rn\u00f6ke, Lorenzo Del Riccio fejlesztett ki egy eszk\u00f6zt, amely kifejezetten mozg\u00f3 t\u00e1rgyak f\u00e9nyk\u00e9pez\u00e9s\u00e9re volt alkalmas. 1937-ben m\u00e1r ezt haszn\u00e1lt\u00e1k a Del Mar Klub verseny\u00e9n. Az \u00e9vek sor\u00e1n folyamatosan tov\u00e1bbgondolt\u00e1k a koncepci\u00f3t, a digit\u00e1lis kamer\u00e1k megjelen\u00e9se azonban mindent megv\u00e1ltoztatott: azonnal \u00e9s egy\u00e9rtelm\u0171en k\u00f6z\u00f6lte a v\u00e9geredm\u00e9nyt.<\/p>\n

Azonban m\u00e9g a modern eszk\u00f6z\u00f6k sem d\u00f6ntenek mindig egy\u00e9rtelm\u0171en: 2010-ben a melbourn-i UCI orsz\u00e1g\u00fati bajnoks\u00e1g 23 \u00e9v alatti koroszt\u00e1ly-verseny\u00e9n legal\u00e1bbis nem ny\u00fajtottak t\u00fal sok seg\u00edts\u00e9get. Amikor Taylor Phinney \u00e9s Guillame Boivin k\u00f6zvetlen\u00fcl a gy\u0151ztes ut\u00e1n szelt\u00e9k \u00e1t a c\u00e9lvonalat, m\u00e9g a Tissot kamera \u00e1ltal k\u00e9sz\u00edtett k\u00e9pek alapj\u00e1n sem lehetett meg\u00e1llap\u00edtani a k\u00fcl\u00f6nbs\u00e9get a k\u00e9t versenyz\u0151 k\u00f6z\u00f6tt. V\u00e9g\u00fcl mindketten bronz\u00e9rmet kaptak. A sport szesz\u00e9lyes j\u00e1t\u00e9k!<\/p>\n","protected":false},"excerpt":{"rendered":"
