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.

Display apparatus

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.

Projection display and image correction method

The image projection system includes a projection-type display apparatus that projects an image onto a projection plane and has a first azimuth detector, the first azimuth detector detecting a projection azimuth; an imaging apparatus that images a projection screen of the image and has a second azimuth detector, the second azimuth detector detecting an imaging azimuth; and a signal processor that performs correction processing of the image. The signal processor includes an estimation unit and a correction unit, the estimation unit estimating an inclination of the projection-type display apparatus to the projection plane on the basis of the projection azimuth detected by the first azimuth detector, the imaging azimuth detected by the second azimuth detector, and the captured image acquired by the imaging apparatus; and the correction unit correcting a shape of the projection screen on the basis of the inclination of the projection-type display apparatus estimated by the estimation unit.

Image projection system and correction method that corrects a shape of a projection plane

This image projection apparatus includes a measurement image that is for measurement of positional displacement between a plurality of colors serving as projection fundamental colors, and a projection section that projects the measurement image toward a projection plane. The measurement image has a plurality of unit images each including graphics of the respective plurality of colors, and the graphics of the respective plurality of colors in each of the unit images have respective barycentric positions that are substantially coincident.

Image projection apparatus, projection imaging system, and correction method

A light source apparatus includes a plurality of light source units, a sensor unit, and an interval control unit. The sensor unit is capable of receiving a plurality of emitted light beams from the plurality of light source units and sampling intensities of the emitted light beams at a predetermined sampling interval. The interval control unit is capable of controlling the predetermined sampling interval on the basis of an output characteristic relating to each of the emitted light beams from the plurality of light source units.

Light source apparatus and image display apparatus

A display device includes: a display unit displaying plural viewpoint images; a light separation unit having plural transmitting portions and separating light from the display unit; and a display control unit controlling the timing of switching either of display positions of respective viewpoint images on the display unit and transmittance of respective transmitting portions of the light separation unit based on correlation information of the viewpoint images between frames.

Display device and display method

Shutter glasses for allowing a user to perceive 3D video includes: a shutter for a right eye and a shutter for a left eye performing open and close operations of shutters in accordance with a timing signal synchronized with 2D video displayed on a display; a detection means for detecting light intensity of linear polarized light; and a shutter control means for controlling ON/OFF for driving the shutter for the right eye and the shutter for the left eye in accordance with the detected light intensity of the linear polarized light.
