摘要： A projection display includes an image display device that displays an image, a projection unit that projects the image displayed by the image display device to a projection surface, a light irradiator that irradiates the projection surface with linear light at an incident angle shallower than an incident angle of projection light, in which the linear light extends along a first direction within the projection surface, an imaging unit that has an optical axis different from an optical axis of the light irradiator, and performs capturing of the projection surface, and a signal processor that performs signal processing on an imaging signal outputted from the imaging unit. The imaging unit performs capturing of the linear light with which the projection surface is irradiated, and the signal processor corrects, on a basis of a captured image of the linear light, a distortion of the projected image.

摘要： 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.

摘要： Setting of an order of sub-frame periods is simplified. A display element array section includes a plurality of arranged display elements in which a gray-scale display is performed in accordance with display data in each frame period that is a display period of one screen. A display control section divides the frame period into a plurality of sub-frame periods and divides the plurality of display elements into a plurality of groups to perform control of a display in each of the plurality of sub-frame periods in each of the plurality of groups. A display data supply section supplies the display data in each of the sub-frame periods to the display element array section by shifting a predetermined delay time in each of the groups and supplies the display data in each of the sub-frame periods to the display element array section on the basis of an order of the sub-frame periods in accordance with the number of the divided groups and the predetermined delay time.
