<P>PROBLEM TO BE SOLVED: To provide an imaging apparatus which clearly photographs required information of an object to be photographed, regardless of ambient illuminance, a state of the object to be photographed, etc. <P>SOLUTION: An imaging apparatus comprises: at least two imaging systems each including an imaging unit which outputs an output signal corresponding to the quantity of light and exposure, an exposure adjusting unit for adjusting the exposure of the imaging unit, and a detection unit which accumulates the output signal to output a photometric value; and an arithmetic unit for controlling the exposure adjusting unit for each imaging system on the basis of the photometric value, wherein the arithmetic unit includes an exposure calculation means for operating a control value controlling the exposure adjusting unit to converge the photometric value to a predetermined value for each imaging system and an illuminance calculation means for operating object illuminance from the photometric value and the control value of the one imaging system, and the exposure of the imaging unit of the other imaging system is controlled in accordance with the object illuminance. <P>COPYRIGHT: (C)2008,JPO&INPIT |
