Abstract

An apparatus that includes a touch panel configured to receive user input, a display configured to show content, a motion quality improvement functionality for the display, at least one sensor configured to detect a pointing device approaching the apparatus, and a control unit configured to selectively activate the motion quality improvement functionality for the display in response to the detection of an approaching pointing device by the sensor.

Claims

1. An apparatus comprising:

a touch panel configured to receive user input,

a display configured to show content,

at least one sensor configured to detect a pointing device approaching the apparatus, and

a control unit configured to selectively instruct activation of a motion quality improvement functionality for the display in response to detection of an approaching pointing device by the at least one sensor and prior to the approaching pointing device touching the touch panel and prior to a moving image being displayed on the display, wherein the motion quality improvement functionality is a functionality to reduce blur on the moving image when the moving image is displayed on the display, wherein the motion quality improvement functionality is initially in a disabled state and the activation of the motion quality improvement functionality comprises bringing up the motion quality improvement functionality, and wherein the control unit is configured to decide whether to activate the motion quality improvement functionality at least on the basis of an application that the approaching pointing device is likely to select and whether said application is likely to need the motion quality improvement functionality because said application is configured to provide a moving image that may blur when displayed on the display.

2. An apparatus of claim 1, wherein the at least one sensor employs proximity sensing technology.

3. An apparatus of claim 1, wherein the touch panel and the display are part of an integrated touch display.

4. An apparatus of claim 1, wherein the at least one sensor is part of the touch panel.

5. An apparatus of claim 1, wherein the at least one sensor and the touch panel are separate components.

6. An apparatus of claim 1, wherein the at least one sensor is configured to detect a movement vector with which the pointing device is approaching the apparatus, and the control unit is configured to decide whether to activate the motion quality improvement functionality at least on the basis of the movement vector.

7. An apparatus of claim 1, wherein the at least one sensor is configured to detect an arrival angle with which the pointing device is approaching the apparatus, and the control unit is configured to decide whether to activate the motion quality improvement functionality at least on the basis of the arrival angle.

8. An apparatus of claim 1, wherein the control unit is configured to determine the gesture the pointing device is likely to make and to decide whether to activate the motion quality improvement functionality at least on the basis of the determined gesture.

9. An apparatus of claim 1, wherein the control unit is configured to decide whether to activate the motion quality improvement functionality at least on the basis of location of the approaching pointing device and the content shown on the display.

10. An apparatus of claim 1, wherein the control unit is configured to decide whether to activate the motion quality improvement functionality at least on the basis of an application that is currently active in the apparatus.

11. An apparatus of claim 1, wherein the control unit is configured to control level of the motion quality improvement functionality in response to the detection of an approaching pointing device and based on speeds and directions of the approaching pointing device versus the touch panel.

12. An apparatus according to claim 1, wherein motion quality improvement functionality is configured to use at least one of:

black frame insertion, backlight blinking, scanning backlight, and pixel overdrive.

13. An apparatus of claim 1, wherein the selectively instructing of activation of the motion quality improvement functionality provides that keeping the motion quality improvement functionality constantly on is avoided to reduce power consumption.

14. An apparatus of claim 1, wherein the selectively instructing of activation of the motion quality improvement functionality provides that the motion quality improvement functionality is fully operational when the pointing device reaches the display.

15. An apparatus of claim 1, wherein the selectively instructing of activation of the motion quality improvement functionality comprises deciding on the basis of the detection of the approaching pointing device whether to activate the motion quality improvement functionality or not.

16. An apparatus of claim 1, wherein the motion quality improvement functionality is selectively disabled.

17. A method comprising:

automatically detecting that a pointing device is approaching an apparatus that comprises a display, and

selectively performing automatic activation of a motion quality improvement functionality for the display in response to the detection of the approaching pointing device, wherein the motion quality improvement functionality is configured to reduce blur on a moving image on the display, wherein the motion quality improvement functionality is activated prior to the approaching pointing device touching the display and prior to the moving image being displayed on the display, wherein the motion quality improvement functionality is initially in a disabled state and the activation of the motion quality improvement functionality comprises bringing up the motion quality improvement functionality, and wherein the motion quality improvement functionality is activated at least on the basis of an application that the approaching pointing device is likely to select and whether said application is likely to need the motion quality improvement functionality because said application is configured to provide a moving image that may blur when displayed on the display.

18. A computer program product comprising a non-transitory computer readable medium having computer executable program code embodied thereon which, when executed by at least one processor of an apparatus that comprises a display, causes the apparatus to:

detect that a pointing device is approaching the apparatus, and

selectively perform activation of a motion quality improvement functionality for the display in response to the detection of the approaching pointing device, wherein the motion quality improvement functionality is configured to reduce blur on a moving image on the display, wherein the motion quality improvement functionality is activated prior to the approaching pointing device touching the display and prior o the moving image being displayed on the display, wherein the motion quality improvement functionality is initially in a disabled state and the activation of the motion quality improvement functionality comprises bringing up the motion quality improvement functionality, and wherein the motion quality improvement functionality is activated at least on the basis of an application that the approaching pointing device is likely to select and whether said application is likely to need the motion quality improvement functionality because said application is configured to provide a moving image that may blur when displayed on the display.
