Image capturing apparatus and image capturing method
First Claim
1. An image capturing apparatus comprising:
- an image capturing unit adapted to capture an image of an object and sequentially acquire image data associated with the image capturing;
a storage unit adapted to store model data associated with a first feature quantity calculated from a feature point of the object in a model image;
a calculation unit adapted to calculate a second feature quantity from a feature point of the object in each of the sequentially acquired image data;
a prediction unit adapted to predict, on the basis of (a) a transition of the second feature quantity and (b) the first feature quantity, a timing when a difference between the first feature quantity and the second feature quantity will satisfy a predetermined condition; and
a control unit adapted to store the image data acquired at the predicted timing in an image data storage unit.

Abstract
In an image capturing apparatus, a video input unit (2) captures the image of an object and sequentially acquires image data associated with the image capturing, a model data memory (6) 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 (3) calculates the second feature quantity from a feature point of the object in the acquired image data, a state change estimation unit (4) 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 (7) stores the image data corresponding to the estimated timing in an image recording unit (5). This configuration makes the image capturing apparatus acquire an image in a more proper state without large-capacity memory.
