CONTROL OF DATA PROCESSING
First Claim
1. Data processing apparatus arranged to receive successive images from a video camera;
- the apparatus comprising;
means for detecting inter-image motion for selected points in an image region associated with a control function of the data processing apparatus; and
means for executing the control function if inter-image motion is detected in the image region;
in which the detecting means is arranged to select points in an image region of a current image that are validated by selecting test points in a currently received image based upon their correspondence with points in a preceding received image, the points in the preceding received image themselves corresponding with the points originally selected in the currently received image, and deselect points in the current image whose corresponding test points do not to substantially coincide.

Abstract
Data processing apparatus arranged to receive successive images from a video camera comprises means for detecting inter-image motion for selected points in an image region associated with a control function of the data processing apparatus; and means for executing the control function if inter-image motion is detected in the image region; in which the detecting means is arranged to select points in an image region of a current image that are validated by selecting test points in a currently received image based upon their correspondence with points in a preceding received image, the points in the preceding received image themselves corresponding with the points originally selected in the currently received image, and deselect points in the current image whose corresponding test points do not to substantially coincide.

28. A data processing method comprising the steps of:
- receiving successive captured images from a video camera;
detecting inter-image motion for selected points in an image region associated with a control function of the data processing apparatus; and
executing the control function if inter-image motion is detected in the image region;
in which the detecting step comprises;
selecting points in an image region of a current image that are validated by selecting test points in a currently received image based upon their correspondence with points in a preceding received image, the points in the preceding received image themselves corresponding with the points originally selected in the currently received image, and deselecting points in the current image whose corresponding test points do not to substantially coincide. - View Dependent Claims (30)
