A technique is disclosed for processing touch signals of a touch-operable touchscreen. One aspect of the method comprises detecting a touch signal indicating a touch on the touchscreen, differentiating, on the basis of the detected touch signal, between an input touch for inputting information and/or for control purposes on the one hand and a gripping touch resulting from a user gripping the touchscreen on the other, and rejecting of the detected touch signal as an input touch if the touch signal is attributed to a gripping touch.

Method and apparatus for processing touch signals of a touchscreen

An example apparatus for rendering frames of an image is caused to measure a processing load of the apparatus, and as a function thereof, estimate a target point in time at which the apparatus may render the next frame. The apparatus is caused to identify a frame having an associated point in time at or after the target point in time, and render the identified frame of the plurality of frames. The apparatus of another aspect is caused to receive an indication of a motional touch gesture to move a GUI element, and in response thereto, direct presentation of the GUI element. The apparatus is caused to extrapolate a position for a point in time based on a number of previous touch positions of the touch gesture. And the apparatus is caused to direct presentation of the GUI element at the extrapolated position at the given point in time.

Processing image content for content motion or touch input

A method for obtaining line synchronization information items from a video signal is proposed. The inventive method is based on convolving the relevant part of an analogue video line signal with a pattern function. The result of the convolution operation is further processed to determine the time instants of the occurrence of the horizontal sync signals. The time instants are subsequently filtered to generate horizontal pulses. A video line memory allows to utilize subsequent horizontal sync signals for calculating the horizontal sync pulse of a current video line. The invention also relates to an apparatus for carrying out the method.
