Three-dimensional input device with displayed legend and shape-changing cursor

An image processing apparatus comprising image displaying means for displaying an image, three-dimensional action detecting means for detecting actions and three-dimensional positions of the hand and the fingers of an operator, cursor generating means for generating operating cursor image data based on the detected result of said three-dimensional action detecting means, processed object generating means for generating image data of a processed object to be operated by an operating cursor displayed based on said operating cursor image data, and display image generating means for synthetically displaying said operating cursor image data and said processed object image data on said image display means, which comprises:

• meaning judging means for judging the meaning of an instruction from the form of action of the hand and the fingers detected by said three-dimensional action detecting means;
• an image memory for storing image data of shape which is shape of operating cursor corresponding to each of processing functions of said image processing means and visually symbolizes each of said functions;
• control changing means for changing the processing function of the image processing apparatus corresponding to the judged result of said meaning judging means;
• cursor changing means for changing the shape of the operating cursor corresponding to the processing function of said image processing means referring to said image data in said image memory;
• legend displaying means for displaying the processing function and plural kinds of operating cursors corresponding to the result of the judgement of said meaning judging means;
• condition setting means for setting a processing operating condition corresponding to each of said operating cursor;
• and
• said processed object generating means generating image data of the processed object corresponding to said processing operating condition.

A method of image processing in which image processing of a processed object is performed by displaying said processed object and an operating cursor on image display means and by operating said operating cursor corresponding to a three-dimensional action of a hand and fingers of an operator. said method comprising steps of:

• storing image data indicative of a plurality of shapes of the operating cursor corresponding to a plurality of processing functions, each of said plurality of shapes visually symbolizing a respective one of said plurality of processing functions;
• judging a meaning of an instruction from a form of action of the hand and fingers detected by a three-dimensional action detecting means;
• changing a processing function of the image processing apparatus corresponding to a judged result of said judging step;
• and
• changing a shape of the operating cursor corresponding to the processing function as changed by said processing function changing step, said shape being changed by referring to said image data;
• and
• displaying a function selecting legend image expressing an image processing function and an operating cursor corresponding to said image processing function.
