20110175980 | SIGNAL PROCESSING DEVICE - In a signal processing device, a first left eye noise extraction circuit and a first right eye noise extraction circuit perform the same noise extraction process. A second left eye noise extraction circuit and a second right eye noise extraction circuit perform different noise extraction processes. The signal processing control circuit controls a selector so that the selector selects the outputs of the left eye noise extraction circuits for a left eye video signal, and the outputs of the right eye noise extraction circuits for a right eye video signal. The correlation detection circuit detects a correlation between the left and right eye video signals, and controls a selector so that the selector selects the output of the first left or right eye noise extraction circuit when the correlation is high, and the output of the second left or right eye noise extraction circuit when the correlation is low. | 07-21-2011 |

20120140924 | VIDEO INPUT DEVICE AND VIDEO DISPLAY SYSTEM - An input processing circuit decodes a digital video signal selected by an input signal selector. Decryption circuits each decrypt the encryption of a video signal output from the input processing circuit, and generate an authentication key of the encryption. A video signal selector selects and outputs one of the video signals output from the decryption circuits, to a monitor. The decryption circuits each include a pseudo-signal generation circuit which extracts information from the video signal, and based on the extracted information, generates a pseudo-video signal. | 06-07-2012 |
