Un pixel<\/strong> (abr\u00e9viation de \u00ab\u00a0picture element\u00a0\u00bb) est l’unit\u00e9 de base d’une image<\/strong> num\u00e9rique. Chaque pixel<\/strong> repr\u00e9sente un point individuel sur un \u00e9cran ou une image, et contient des informations de couleur. L’ensemble des pixels<\/strong> forme l’image<\/strong> que l’on voit sur un \u00e9cran<\/strong> d’ordinateur, un t\u00e9l\u00e9phone ou dans une photo num\u00e9rique.<\/p>

Les pixels<\/strong> sont g\u00e9n\u00e9ralement organis\u00e9s en une grille, et la densit\u00e9 de pixels (le nombre de pixels par pouce, ou PPI<\/strong>) d\u00e9termine la clart\u00e9 et la r\u00e9solution<\/a><\/strong> de l’image<\/strong>. Plus il y a de pixels<\/strong> dans une image, plus la r\u00e9solution<\/strong> est \u00e9lev\u00e9e et plus l’image<\/strong> appara\u00eet nette.<\/p>

Dans le contexte des \u00e9crans<\/strong>, le nombre total de pixels<\/strong> est souvent exprim\u00e9 par la r\u00e9solution<\/strong>, par exemple 1920×1080 pixels, ce qui signifie qu’un \u00e9cran affiche 1920 pixels en largeur et 1080 pixels en hauteur.<\/p>

En r\u00e9sum\u00e9, un pixel<\/strong> est la plus petite unit\u00e9 d’une image num\u00e9rique, et il joue un r\u00f4le cl\u00e9 dans la qualit\u00e9 et la nettet\u00e9 des images sur les appareils \u00e9lectroniques.<\/p>
