Abstract
An imaging apparatus is disclosed which comprises a first image signal generation section generating a first image signal in a first exposure time, a second image signal generation section generating a second image signal in a second exposure time, an image combining section combining the first and second image signals into a composite image signal, an integrated value calculation circuit determining the average luminance values of the first and second image signals, a peak value detection circuit detecting the peak values of the first and second image signals, an exposure time control section responsive to the integrated value and the peak value controlling the first and second exposure times, and a gain control circuit controlling the amplitude of each of the first and second image signals to be applied to the image combining section individually.
