Display apparatus and method for motion recognition thereof

A method for recognizing an external motion with a display apparatus, the method comprising:

• changing the display apparatus from an overall area motion recognition mode to a partial area motion recognition mode;
• recognizing the external motion that is input in an active area set in the partial area motion recognition mode;
• and
• changing the partial area motion recognition mode to the overall area motion recognition mode in response to the recognized external motion matching a stored disabling motion to disable the partial area motion recognition mode,
• wherein the active area is a relative area in a screen of the display apparatus configured to recognize the external motion that is externally input to the display apparatus through a camera.

A method for recognizing an externally input motion with a display apparatus, the method comprising:

• setting an active area in which the externally input motion is recognizable, wherein the active area corresponds to a portion on a screen of the display apparatus;
• changing the display apparatus from an overall area motion recognition mode to a partial area motion recognition mode, wherein the partial area motion recognition mode comprises a first partial area motion recognition mode in which the partial area motion recognition mode is disabled in response to a first motion being a first disabling motion, and a second partial area motion recognition mode in which the partial area motion recognition mode is maintained in response to the first motion being a second disabling motion;
• recognizing the first motion in the active area;
• entering a second partial area motion recognition mode in which the partial area motion recognition mode is maintained in response to the first motion being the second disabling motion;
• and
• recognizing a second motion in the active area which is in the second partial area motion recognition mode.

A display apparatus comprising:

• a display configured to display multimedia content;
• a camera configured to receive an external motion;
• and
• a controller configured to control the display and the camera,
• wherein the controller is further configured to change a partial area motion recognition mode to an overall area motion recognition mode in response to the external motion being input in an active area through the camera matches a disabling motion configured to disable the partial area motion recognition mode.

A display apparatus comprising:

• a display configured to display multimedia content;
• a camera configured to receive an external motion;
• and
• a controller configured to control the display and the camera,
• wherein the controller is further configured to recognize a user motion that is received only in an active area using the camera when the display apparatus is in a partial area motion recognition mode, and display a user motion recognition result corresponding to the recognized user motion on the display.

A display apparatus comprising:

• an image sensor including a viewing frustum and configured to receive a gesture only from within a sub-portion of the viewing frustum in a partial recognition mode, and configured to receive the gesture anywhere in the viewing frustum in a overall recognition mode;
• and
• a screen that corresponds to the viewing frustum and is configured to display content,
• wherein the sub-portion of the viewing frustum corresponds to an active area on a corresponding portion of the screen.

A display apparatus comprising:

• an image sensor including a field of view and configured to receive a gesture only from within a sub-portion of the field of view in a partial recognition mode, and configured to receive the gesture anywhere in the field of view in a overall recognition mode;
• and
• a screen that corresponds to the field of view and is configured to display content,
• wherein the sub-portion of the field of view corresponds to an active area on a corresponding portion of the screen.
