Abstract: A pulse-width modulated backlight control for a video display restarts the pulse-width modulated pulse train on occurrence of a video refresh pulse. In order to prevent an undesirable momentary increase in brightness in the event that the last pulse of the pre-refresh pulse train occurs too close to the first pulse of the post-refresh pulse train relative to the normal pulse interval, the width of the first pulse following refresh may be reduced from a first value determined by the desired brightness to a second value that bears the same proportion to the first value that the interval between the beginning of the previous pulse and the occurrence of the refresh pulse bore to the normal pulse interval. In that way, the duty cycle during the shortened pulse interval is the same as during a normal pulse interval, avoiding or minimizing perceptible increase in backlight brightness.

Abstract: To provide an input apparatus, a control apparatus, a control system, and a control method that are capable of restricting a movement of a pointer on a screen by a user operation even while the input apparatus is moving. In a state where a movement button is not pressed by a user, an MPU of an input apparatus is not outputting a movement command or is outputting a movement command with a displacement amount set to 0. In other words, even when the user holds the input apparatus and moves it, a pointer does not move on a screen. As a result, a movement of the pointer unintended by the user can be restricted. When the movement button is pressed, that is, when a first operation signal is input via a first switch, the MPU starts outputting the movement command. By receiving the movement command, an MPU of a control apparatus controls display of the pointer so as to start the movement of the pointer that corresponds to the movement command.

Abstract: We present a method for predictive compression of time-consistent 3D mesh sequences supporting and exploiting scalability. The applied method decomposes each frame of a mesh sequence in layers, which provides a time-consistent multi-resolution representation. Following the predictive coding paradigm, local temporal and spatial dependencies between layers and frames are exploited for layer-wise compression. Prediction is performed vertex-wise from coarse to fine layers exploiting the motion of already encoded neighboring vertices for prediction of the current vertex location. Consequently, successive layer-wise decoding allows to reconstruct frames with increasing levels of detail.
