摘要： A focus area contains one or more areas, into which an image signal captured by an image sensor (14) is segmented by an image segmentation section (15). The focus area follows movement of an object in accordance with feature point positional information of an image extracted by a feature point extraction section (34) and a feature point positional calculation section (35). Further, after a low-pass filter (36) extracts a low frequency component of a time-series oscillation frequency using the feature point positional information, and a focus area selection section calculates a display position, the focus area is displayed on a display section (17). Therefore, an imaging device, which does not cause discomfort even when the focus area displayed on the display section (17) fluctuates by tracking movement of the object, is provided.
