  1. Danke
    zohanji hat auf stefan.macke in Bildgröße berechnen, Adressen   
    1) Du rechnest beides in Bit um:
    Bilder: 20 * 3 * 1.024 * 1.024 * 8 Bit = 503.316.480 Bit
    USB: 480 * 1.000.000 Bit/s = 480.000.000 Bit/s
    Übertragungsdauer: 503.316.480 Bit / 480.000.000 Bit/s = 1,048576 s = 1,05 s
    2) PPI = pixels per inch, also jeweils 600 Pixel pro 2,54 cm.
    Deine Rechnung fortsetzen:
    DIN A4 in Inch:
    21 cm / 2,54 cm/Inch = 8,27 Inch (Achtung: Rundungsfehler bei dir)
    29,7 cm / 2,54 cm/Inch = 11,69 Inch
    Inch in Pixel:
    8,27 Inch * 600 px/Inch = 4.962 px
    11,69 Inch * 600 px/Inch = 7.014 px
    Anzahl Pixel im Bild:
    4.962 * 7.014 px = 34.803.468 px
    Anzahl Bit im Bild:
    34.803.468 px * 16 Bit/px = 556.855.488 Bit
    Bit in MByte (Achtung: Faktor 1.000.000, da MB und nicht MiB angegeben):
    556.855.488 Bit / 8 / 1.000.000 = 69,61 MB
