An imaging apparatus capable of capturing a moving image with an imaging device is equipped with a first image-processing device that uses hardware to process images captured by the imaging device and a second image-processing device that processes captured images with software. The imaging apparatus includes an image-processing switching device that selectively operates one of either the first image-processing device or the second image-processing device. The imaging apparatus includes a light-detection device that detects the amount of light received by the imaging device and a sensitivity adjustment device that increases the sensitivity of the imaging device as the amount of light decreases. The image-processing switching device operates the first image-processing device when the sensitivity is lower than a predetermined value and operates the second image-processing device when the sensitivity is higher than the predetermined value.
