Tak CZ navod hovori toto:
Nastavení automatické úpravy jasu v iPhone: Vyberte Brightness a zapněte nebo
vypněte volbu Auto-Brightness. Pokud je volba Auto-Brightness zapnutá, iPhone
upraví s užitím vnitřního čidla světla prostředí jas obrazovky podle stávajících
světelných podmínek.
O´REILLY-ho "iPhone The Missing Manual (second edition)" hovori toto:
If Auto-Brightness is turned on, then the changes you make here are
relative to the iPhone?s self-chosen brightness. In other words, if you
choose the brightness by 20 percent, the screen will always be 20 percent
brighter than the iPhone would have chosen for itself.
Takze pokial tomu dobre rozumiem tak:
Ak pouzijete Auto-Brightness tak zmeny, ktore tu urobite su podobne tym, ktore si iPhone nastavi sam. Inymi slovami, ak nastavite jas na 20 percent, jas bude vzdy o 20 percent vyssi, ako by si nastavil iPhone sam.
Okrem toho O´Reilly pise:
Dimming the screen - In bright light, the screen brightens (but uses
more battery power). In dim light, it darkens.
This works because of an ambient-light sensor that?s hiding behind the glass
above the earpiece. Apple says that it tried having the light sensor active all the
time, but it was weird to have the screen constantly dimming and brightening
as you used it. So the sensor now samples the ambient light and adjusts the
brightness only once?when you unlock the phone after waking it.
