  • Patent number: 8159561
    Abstract: This invention includes an imaging device that photographs a subject image, a first storage device that stores image data output from the imaging device at a first time interval, a display device that reads the image data stored in the first storage device at the first time interval and display the image data, a second storage device that reads the image data stored in the first storage device at a second time interval and stores the image data and a feature extraction device that extracts a feature section of the subject based upon the image data stored in the second storage device. Therefore, image data output from the imaging device for an image display is once stored in the second storage device and the feature section is extracted from the stored image data, so an extraction is not affected by an update of the first storage device.
