20100091098DISPLAY APPARATUS, DISPLAY METHOD, AND DISPLAY SYSTEM - A display apparatus includes: a video display unit that converts a video signal containing information indicating the magnitude of disparity between left-eye and right-eye video images into video images and displays the video images on a screen; a projection distance detector that detects a projection distance that is the distance between the video display unit and the screen; a display size calculator that calculates the size of the video images displayed on the screen using the projection distance detected by the projection distance detector; a disparity magnitude detector that detects the information indicating the magnitude of disparity from the video signal; and a disparity magnitude adjuster that adjusts the magnitude of disparity using the size of the video images displayed on the screen and the information indicating the magnitude of disparity detected by the disparity magnitude detector.04-15-2010
20100118120TRANSMITTER, RECEIVER, SIGNAL TRANSMISSION SYSTEM, AND SIGNAL TRANSMISSION METHOD - A transmitter is provided. When a three-dimensional image signal including a two-dimensional image signal and depth information of the two-dimensional image signal is transmitted to a receiver using a two signal transmission lines, the three-dimensional image signal including the two-dimensional image signal and the depth information of the two-dimensional image signal is input. Also, signal separation of the two-dimensional image signal is performed. In addition, one signal-separated part of the two-dimensional image signal is transmitted to a first signal transmission line and the other signal-separated part of the two-dimensional image signal is combined with the depth information and then transmitted to a second signal transmission line.05-13-2010
20100157090IMAGING APPARATUS, IMAGING METHOD, RECORDING MEDIUM, AND PROGRAM - An imaging method, a recording medium, and a program which are capable of processing imaging data of a high rate in a manner similar to that of a normal frame rate. Image data captured by a solid-state imaging element capable of performing imaging at a high resolution and a high frame rate is supplied to a memory control unit. The memory control unit, at the same time as writing the imaging data input from the imaging element in a frame memory, reads preceding frames of imaging data that are recorded on the frame memory, and sequentially respectively outputs them in parallel, as video image data items for each frame, to respective camera signal processing units. Then, in the camera signal processing units, a video output unit, a viewfinder output unit, codec units, and recording units, processing similar to that in the case of a frame rate that is ΒΌ the imaging frame rate is executed.06-24-2010

20100295929SYNCHRONIZATION CIRCUITS AND METHODS USABLE IN SHUTTER GLASSES - Described herein are circuits and methods enabling a user to view 3D video using shutter glasses. The shutter glasses can wirelessly receive a video synchronization signal to synchronize the timing of a shutter operation with the timing of displayed video. A self-timing signal can be generated based on a measured period of the video synchronization signal. A low-power mode of operation can be entered for a period of time in which reception of the video synchronization signal is disabled and the shutter operation is controlled based on the self-timing signal.11-25-2010
