1. An image processing apparatus comprising:
- extracting means for extracting a feature point from a captured image;
recognizing means for recognizing a position of the feature point;
display control means for performing control, based on the position of the feature point, to display a feature-point pointer indicating the feature point, and a plurality of predetermined user interfaces;
gesture recognizing means for recognizing a grab gesture, wherein a volume of space is enclosed within a user'"'"'s palm, the volume of space corresponding to a volume of space surrounding the feature-point pointer; and
issuing means for issuing, based on the position of the feature point, a command corresponding to the position of the feature point or a motion of the feature point,wherein the display control means displays the plurality of predetermined user interfaces in a predetermined pattern surrounding the feature-point pointer, andwherein the command issued by the issuing means is capable of terminating the display of the plurality of user interfaces, the termination being triggered by detection of a predetermined gesture that results in the feature-point pointer being moved from inside a circular region encompassing the plurality of user interfaces to outside said region.

6. An image processing method for an image processing apparatus configured to extract a feature point from a captured image, the image processing method comprising the steps of:
-
extracting the feature point from the captured image; recognizing a position of the feature point; displaying, based on the position of the feature point, a feature-point pointer indicating the feature point, and a plurality of predetermined user interfaces; recognizing a grab gesture, wherein a volume of space is enclosed within a user'"'"'s palm, the volume of space corresponding to a volume of space surrounding the feature-point pointer; and issuing, based on the position of the feature point, a command corresponding to the position of the feature point or to a motion of the feature point, wherein the plurality of predetermined user interfaces are displayed in a predetermined pattern surrounding the feature-point pointer, and wherein the command issued is capable of terminating the display of the plurality of user interfaces, the termination being triggered by detection of a predetermined gesture that results in the feature-point pointer being moved from inside a circular region encompassing the plurality of user interfaces to outside said region.
