The present invention relates to a 3D time-of-flight camera for acquiring information about a scene, in particular for acquiring depth images of a scene, information about phase shifts of a scene or environmental information about the scene. The proposed camera particularly compensates motion artifacts by real-time identification of affected pixels and, preferably, corrects its data before actually calculating the desired scene-related information values from the raw data values obtained from radiation reflected by the scene.

A TFT panel includes (i) a plurality of signal electrodes, (ii) a plurality of scanning electrodes which cross the plurality of signal electrodes, (iii) an active element provided in a vicinity of each intersection at which one of the plurality of signal electrodes and one of the plurality of scanning electrodes cross and connected to the one of the plurality of signal electrodes and the one of the plurality of scanning electrodes, (iv) a pixel electrode driven by the active element, and (v) a counter electrode to which an AC signal is applied, and which faces the pixel electrode. The REVC signal generating circuit generates a counter electrode generating signal, which is to be generated into a counter electrode driving signal by a counter electrode signal generating circuit, in synchronism with a horizontal synchronizing signal in such a manner that the polarity is inverted every horizontal period, and, when one polarity has a length of periods longer than the other polarity during one vertical period, the both polarities of the counter electrode have the same root-mean-square value of voltage during one vertical period by inverting the polarity having the longer period at any timing. With this, it is possible to reduce a low-frequency sound caused by piezoelectricity of a liquid crystal capacitance.

Systems and methods of adjusting a pre-alarm time are provided, including detecting, by a sensor, an entry into a building by a person and generating detection data according to the detected entry. A processor communicatively coupled to the sensor adjusts a pre-alarm time according to the detection data. An alarm is output, by an alarm device communicatively coupled to at least the processor, according to the detection data and the adjusted pre-alarm time.
