The present invention relates to a lighting control device, the device comprising means for receiving a trigger; and means for switching operation of a lighting device from a continuous mode to a flash mode upon receipt of said trigger; wherein said lighting device comprises at least one light emitting diode; and said flash mode is at a higher brightness than said continuous mode. The invention also relates to a lighting system comprising: a lighting device comprising at least one light emitting diode; and a lighting control device; wherein the lighting control device is operable to switch operation of said lighting device between a continuous mode and a flash mode; wherein the flash is at a higher brightness than said continuous mode.

An image pickup apparatus that is capable of reducing influence of abnormal reflection light at pre-emission upon determination of an emission amount for main photographing. The image pickup apparatus calculates reflection luminances of reflected light from an object at pre-emission of a lighting device, detects a face area from an image, divides the face area into blocks, calculates a face reflection luminance from a weighted average of reflection luminances of the blocks and first weights of the blocks, calculates a face ambient light luminance from a weighted average of ambient light luminances of the object of the blocks and second weights of the blocks, and determines an emission amount of the lighting device for main photographing with using the face reflection luminance and the ambient light luminance. A first weight of an abnormal luminance block is reduced than that of a block other than the abnormal luminance block.

A photographing system which can securely set a manual light amount to an appropriate light emission amount after changing the manual light amount of a strobe according to a photometry result at the time of pre-light emission. In the photographing system, when a light-emission amount automatic adjustment in a metered manual starts in a manual light-emission mode after setting a light emission amount of the light-emitting part in the main light emission within a first range by a user operation in the manual light-emission mode, a main appropriate light emission amount is calculated on a basis of a photometry result before and after the pre-light emission by a photometric circuit, then in a case where the calculated main appropriate light emission amount falls within a second range and is outside the first range, the light emission amount of the light-emitting part in the main light emission is changed to the main appropriate light emission amount, wherein the second range, wherein the second range, including the first range and wider than the first range, is possible to perform automatic light adjustment in the illumination apparatus.
