| description | A camera device (1) includes an imaging unit (2) which outputs a long exposure signal and a short exposure signal in one field period. A face detection unit (8) detects a face area from an image captured by the imaging unit (2). The weighting processing unit (12) applies a weighting process to luminance data of the long exposure signal in the detected face area using a weighting constant for reducing the luminance level of the long exposure signal. If the luminance level of the weighting-processed long exposure signal rises to a predetermined saturation level or higher, an exposure control unit (15) performs exposure control using the long exposure signal and the short exposure signal. This can suppress occurrence of a noise due to a short exposure signal (flickering) in the face area, thereby improving visibility in the face area. |
