Abstract
An imaging apparatus having a wide dynamic range, including an imaging unit, an exposure control unit realizing a plurality of the imaging processes on the same object with different sensitivities by controlling the exposure of the imaging unit, a camera signal processing unit generating a video signal by processing the camera signal from the imaging unit, a video synthesis unit synthesizing a plurality of video signals having different sensitivities generated by the processing unit, and an object recognition unit processing the video signals from the processing unit and detecting the object information. The object recognition unit detects the object information for each of the plurality of the video signals. Based on the detected object information, the control unit controls the exposure, the processing unit controls the gamma characteristic of the video signals, and the synthesis unit controls the ratio for synthesizing the plurality of the video signals.
