Image capturing apparatus and image capturing method

Abstract

In an image capturing apparatus, a video input unit () captures the image of an object and sequentially acquires image data associated with the image capturing, a model data memory () stores model data associated with the first feature quantity calculated from a feature point of the object in a model image, a principal object detection unit () calculates the second feature quantity from a feature point of the object in the acquired image data, a state change estimation unit () estimates, on the basis of the second feature quantity and the model data, the timing when the object satisfies a predetermined condition, and an image input processing control unit () stores the image data corresponding to the estimated timing in an image recording unit (). This configuration makes the image capturing apparatus acquire an image in a more proper state without large-capacity memory.
