1. a kind of camera apparatus, comprising:

  • Flash modules, including LED matrix, including multiple LED elements;

    WithLED control unit;

    Determine by by include LED matrix output light spatial intensity distribution, the wherein spatial intensity distribution packet of lightInclude output intensity;

    AndControlling LED matrix output in one or more substantially burst of light of moment has identified spatial-intensity pointThe light of cloth is by making at least the first LED element of the LED matrix export the light of the first intensity and by making the LEDIt is one or more right to irradiate that at least the second LED element output of matrix is different from the light of the second intensity of first intensityAs,Wherein;

    The equipment determines first distance between the first object to be captured in the equipment and in the picture and sets describedSecond distance between the second standby and to be captured in the picture object;

    AndDetermine that the first distance and the second distance, the LED control unit make at least first in response to the equipmentLED element export the light of the first intensity be radiated at the equipment at the first positioning of the first distance described theAn object;

    Wherein the LED control unit make at least the second LED element export the light of second intensity be radiated at it is describedSecond object of the equipment at second positioning different from first positioning of the second distance;

    AndLight wherein from least the first LED element is radiated at first object at first positioning, be simultaneously toThe light of few second LED element is radiated at second object at second positioning.
