Abstract: Motion-based control of an electronic device uses an array of at least three reference elements forming a triangle. An image sensor (e.g., a video camera), which may be located on a user-manipulated device, captures an image of the array. The array image has a pattern formed by a nonparallel projection of the reference triangle onto the image sensor. The pattern carries information of the relative position between the image sensor and the reference element array, and changes as the relative position changes. The pattern is identified and used for generating position information, which may express a multidimensional position of the user-manipulated device with respect to three axes describing a translational position, and three rotational axes describing pitch, roll and yaw motions. The control system and method are particularly suitable for videogames.

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.

The LCD panel includes a first substrate having a storage electrode and a pixel electrode, a second substrate having a common electrode, and a liquid crystal layer interposed between the first and second substrates. The LCD panel has an alignment interval during which liquid crystal molecules are transitioned from a splay state to a bend state and a normal operating interval during which an image is displayed in the bend state. The power supply section supplies a first alignment voltage that is higher than the data voltage to the common electrode and supplies a second alignment voltage that is lower than the data voltage to the storage electrode, during the alignment interval. Thus, a transition speed from a transient splay state into a bend state is enhanced, so that an alignment interval may be decreased.
