Image pickup device
专利汇可以提供Image pickup device专利检索，专利查询，专利分析的服务。并且PURPOSE: To operate a satisfactory white balance adjustment at the time of a proximity image pickup by providing a correcting means which adds a correction to a white balance adjusting means at the time of detecting the usage of a macro lens or the usage of the macro area of an image pickup lens.
CONSTITUTION: In a macro lens using state, a flicker component F of an outside light is led-through from the output of a light measuring sensor 15, and compared with a reference value F
o . Then, in the case of F o , the flicker component F is defined as a non-flicker light source, and in the case of F≥F
o , it is defined as a flicker light source, that is, a fluorescent lamp. Control voltages R
c and B
c obtained like this are transmitted through a D/A converter 14 to R and B gain controlling parts 5 and 6, each color difference signal level is changed, and the white balance adjustment is satisfactorily operated based on the changed output.
