    Default Understanding Camera sensor size

    Hello
    I see alot of cameras with sensor size of 1/2.5"
    What does this mean?
    the sensor is 1" high and 2.5" long? .. this seems like a huge sensor
    I must be reading it wrong

    Pls advise

    Cyrn, I still dont understand,
    does this mean that the vertical is 1" and the horizontal is 2.29" ?
    and the diagonal is 2.5" ? This looks big

    or, the sensor diagonal is 0.4mm ? This looks awfully small

    Most PnS sensors have aspect ratio of 4:3, so Pythagoras theorem would give the diagonal a ratio of 5. The sensor size given as 1/2.5" = 0.4", which means the length is 0.32" and the height is 0.24".

    Yes, these sensors are very small.
