Lighting apparatus and image pick-up apparatus with lighting

摘要

A lighting apparatus in which plural light emitting devices for illuminating light to an object to be illuminated from the periphery thereof are put to light control, and a control device is provided for controlling light to the light emitting devices on every segment divided isogonally with respect to the lighting center at which the light is focused by a control device, wherein the control device 6 comprises an illuminance distribution setter 7 that sets the illuminance on every segments S1 to S4 individually in accordance with the start position of a vector that represents the lighting direction to the lighting center F on the XY coordinate plane D with the lighting center F being as an origin P0, and a light controller 9 that reads out the illuminance on every segment from the illuminance distribution setter 7 in accordance with the input data from a two dimensional data input device 8 that sets the start position and controls the light.
